However, as these codes become more comprehensive, they become more challenging to manage and meet. Homeowners, developers, architects, engineers, builders, and government officials spend significant amounts of time dissecting and working with the code. \n\nThe code ecosystem is not only incredibly dense but also constantly changing. We host over 5 million code sections and 1,700+ state and city codes, [update over 7,000 sections per month (on average)](https://up.codes/code-accuracy), and host over 160,000 local amendments. Other challenges include the difficulty of working across multiple jurisdictions and maintaining firm-wide code expertise. \n\n# **Current AI tools are limited**\n\nGeneric AI chatbots (like ChatGPT, Google Bard, Bing Chat, etc.) work from out-of-date code and is not jurisdiction-specific. Because the codes change dramatically across adoption cycles and jurisdictions, for many codes, UpCodes is often the only place that is continually integrating local amendments or changes to the code.\n\n# **Introducing UpCodes Copilot**\n\nAt UpCodes, we envision a world where architects, engineers, contractors, and everyone involved in the building compliance lifecycle can work together seamlessly and harness the power of AI to create safer buildings. We’re in the early innings of that future, and it’s why we’re excited to announce UpCodes Copilot. \n\n![uploaded image](/media/?type=post&id=72667&key=user_uploads/147166/5481c27f-f364-4ce9-9449-de817a1bf363)\n\nOur vision is that Copilot becomes an indispensable research assistant for designers, builders, plan reviewers, and plan examiners. Instead of manually parsing through dense code sections, Copilot accelerates code research process by instantly delivering tailored responses to any code query. With Copilot you can: \n\n* **Research faster** – Go beyond manually gathering code sections from various codes and chapters. \n* **Be more efficient** – Catch sections you may have missed and better manage compliance. \n* **Gain insight** – Unlock the ability to parse through massive quantities of code.\n\n# **Who Copilot is for**\n\nUpCodes Copilot is for anyone involved in the code compliance lifecycle. Most architects, engineers, and general contractors already know how cumbersome and difficult it is to gather context and gain insight into what the code is saying. Wherever someone is in the architectural design process, whether they’re designing, building, or managing occupancy, Copilot will accelerate their understanding of the code.\n\n# **How Copilot works**\n\nCopilot builds on our powerful search that surfaces relevant content across our 5+ million code sections by directly answering tough code questions. Its responses are based on analysis across multiple code sections (including tables and charts!) as well as basic calculations. And best yet, Copilot always cites the sections it pulls from so anyone can validate the response and deepen their code expertise.\n\n![uploaded image](/media/?type=post&id=72667&key=user_uploads/147166/1e0ce9d8-73f1-4e6b-9527-6641b8b15322)\n\n([video](https://www.youtube.com/watch?v=695G3xNKk_o))\n\n# **What you can use Copilot for**\n\n* **Ask a code question** – Ask code questions for a specific jurisdiction and adoption cycle and get answers that point out the relevant code sections.\\\n Example: “I have a parking lot with 200 spaces. How many van-accessible spaces do I need?”\n* **Explain a concept or code section** – Get detailed explanations for complex concepts or specific code sections. \\\n Example: “Can you explain what 'fire separation distance' means in the context of building code?\"‍\n* **Find related sections** – Identify code sections that correspond to a specific topic you’re researching. \\\n Example: \"Find all sections related to plumbing codes in a residential building.\"\n* **Perform a calculation** – Provide your project parameters to Copilot and let it calculate the code requirements for you. \\\n Example: “Help me determine the maximum occupancy of a building, given its size…”‍\n* **Summarize what the code is saying** – For lengthy code sections, ask Copilot to give you an overview of the key points.\\\n Example: \"Summarize the key points from Section 101.2 of CBC 2022.\"‍\n* **Generate a checklist for a focus area** – Get a tailored checklist for that specific focus area to help you ensure all requirements are met. \\\n Example: “Provide a checklist for designing a Type 1 grease duct for a fryer in a commercial kitchen. The kitchen is on the ground floor of a 3-story building. Ventilation equipment will be placed on the roof.”\n\n# **Ask**\n\n* If you would like to try Copilot, sign up for an [UpCodes trial](https://upcodes.ai) to test it out for free! \n* If you know of any architecture, engineering, or general contracting firms, we would love to chat!

AI-assistant for construction bidding", "tagline": "Downtobid gives construction estimators an AI-assistant to make bidding faster. ", "body": "# **TLDR**\n\n[Downtobid](https://downtobid.com/) is building AI to understand construction blueprints. Our first product is a modern bidding tool equipped with an AI assistant to make bidding faster.\n\n# **The Problem**\n\nConstruction blueprints are very difficult to read and understand, which makes bidding slow and expensive for construction teams. Bidding is the process of getting a set of blueprints and reaching out to subcontractors to get prices on each scope of work (e.g., drywall, electrical, mechanical), then compiling these quotes into a single estimated price for the project.\n\nFor example, here's a 474-page PDF for a new wellness center (a medium size project). A general contractor needs to understand all the intricate details of this project in order to price it effectively.\n\n![uploaded image](/media/?type=post&id=80238&key=user_uploads/252451/3c08be04-5f62-45ee-aaa4-dae24483c74c)\n\nEvery page contains a lot of information about materials that need to be purchased (e.g., which walls should be added, and specifications for the lighting system).\n\n![uploaded image](/media/?type=post&id=80238&key=user_uploads/252451/6903f0a7-6817-4aef-b5bd-67f30b53f6c6)\n\n# **The Solution**\n\nDowntobid is an all-in-one bidding tool equipped with an AI assistant that streamlines every part of the bidding process for general contractors, from understanding the construction plans to reaching out to vendors.\n\n### _AI to find scope of work_\n\nToday, GCs spend 2-3 hours per project reading large construction documents to figure out what vendors they need to get quotes from. With Downtobid, GCs simply upload a set of plans and AI instantly calls out which scopes of work are required and highlights them on the actual set of plans. Rather than read blueprints raw, GCs get an annotated version with all important info called out.\n\n![uploaded image](/media/?type=post&id=80238&key=user_uploads/252451/9723f21b-081c-4a34-b838-52c113f8c81f)\n\n### _AI to build project-specific subcontractor lists_\n\nToday, GCs need to build custom subcontractor lists based on their project requirements. Not every subcontractor is a good fit for the project (e.g. you wouldn't invite a wood-flooring sub to a building that requires carpet flooring). With Downtobid, AI auto-recommends a list of subs based on their expertise, experience, and project requirements.\n\n![uploaded image](/media/?type=post&id=80238&key=user_uploads/252451/13887d59-73f9-468a-a671-6ab3d3e2a924)\n\n_AI orchestrates the outreach process_\n\nToday, GCs have to send emails, set up Dropbox links (to host their plans), and send follow-up emails. With Downtobid, AI prepares your email campaign and automatically follows up with subcontractors when they don't respond. A GC simply needs to respond to emails in their inbox and wait for proposals to come back.\n\n![uploaded image](/media/?type=post&id=80238&key=user_uploads/252451/44db1129-ebe1-42de-b495-5a7ca8def8cd)\n\n**Long-term vision**\n\nOur long-term plan is to create intelligent AI that can understand and interpret construction blueprints. We started with bidding has the lowest requirements for AI so it's the quickest way to market. As the AI for construction gets more intelligent, we'll be able to handle more and more construction workflows. For example, we’re starting to annotate plans so LLMs can better understand the structure of construction blueprints.\n\n![uploaded image](/media/?type=post&id=80238&key=user_uploads/252451/b4e77874-f0f2-4ee4-b1c9-7acbf773c545)\n\n**Team**\n\nWe spent the last 5 years working together on another bidding product (for subs) called BasisBoard. Previously, Andy worked at Uber on self-driving cars, and Kev worked at Boston Consulting Group as a designer.\n\n![uploaded image](/media/?type=post&id=80238&key=user_uploads/252451/5d7e3304-3d0f-4945-9318-4e0eb226af45)\n\n**Ask**\n\nWe'd love intros to general contractors, especially those who are building retail projects (e.g., Walmart, Lululemon, Dior, McDonald's, etc.).

It scores 81.6% on our benchmark — ahead of human estimators (77.6%) and \\~20 points clear of the best frontier model. It runs in \\~2 hours vs. up to a week for a human.\n\n![uploaded image](/media/?type=post&id=106241&key=user_uploads/428748/ccaeb6b3-ba3f-4330-acd0-8e8ff779cca2)\n\n\n**The problem**\n\nBefore a contractor can bid a job, someone has to do a takeoff: read every sheet, count materials trade by trade, measure walls and roofs, cross-reference dimensions that live on different pages. It takes an experienced estimator 8–20 hours per project and years of training to do at all. It's the tax on every bid in a huge, fragmented industry.\n\nYou'd think a frontier model could do this now. It can't. Foundation models today aren't capable of understanding construction drawings to a level that is actually useful for a construction business. So this massive $2 trillion industry still runs on blueprints that are being analyzed by humans pretty much the same way they have been for the last few hundred years.\n\n**What we built**\n\nHandoff has developed H1: an AI model that understands and analyzes blueprints better than a human estimator, thus resolving this manual bottleneck once and for all.\n\n![uploaded image](/media/?type=post&id=106241&key=user_uploads/428748/e3a9fd8f-cdf2-48f1-b4d6-9e30aa807ec5)\n\nH1 has three layers:\n\n* **Scope analysis** — a detailed, trade-by-trade breakdown of what the project actually involves, read straight from the drawings.\n* **Takeoff with quantities** — a complete material quantity list per trade: framing members, sheets, linear and square footage, counts, all with units.\n* **Localized construction costs** — accurate pricing on those quantities, localized to your ZIP code.\n\nAll of it programmatic and autonomous. No human needs to be involved in the process of creating the entire takeoff. You can simply upload plans and get structured scope, quantities, and costed output back.\n\n**The benchmark (TakeoffBench-V1)**\n\nAs part of this, we are also releasing the industry's first takeoff benchmark that enables us and anybody else in the research community to compare models against 15 real, permissioned, PII-stripped residential blueprint sets, each paired with a consensus-validated expert takeoff.\n\n![uploaded image](/media/?type=post&id=106241&key=user_uploads/428748/b4f0b802-c841-403e-8867-5b1ac2e9fcb2)\n\n![uploaded image](/media/?type=post&id=106241&key=user_uploads/428748/abdfeb2b-4ed7-4764-bc47-a6305f6d8ff9)\n\nHere's how we performed on the benchmark:\n\n* Handoff-H1: 81.6%\n* human estimator (with takeoff software): 77.6%\n* best frontier model (Claude Fable): 61.4%\n\nThe rest cluster in the low-to-mid 50s (gpt-5.6, Claude, Kimi) down to 34.7% (DeepSeek-V4-Pro).\n\n**Try it**\n\nH1 is live in the [Handoff](https://handoff.ai) product and on the API. We have one of the world's largest suppliers already using our model in every one of their locations across the country, including thousands of projects every month.\n\nIf you're looking for an intelligence layer to extract detailed structured data from blueprints with construction costs priced out to the nearest cent, hit us up at [api@handoff.ai](mailto:api@handoff.ai)", "url": "https://www.ycombinator.com/launches/RdZ-handoff-h1-a-takeoff-model-that-outperforms-human-estimators", "votes": 7, "created_at": "2026-07-22T20:04:49.600Z" }, { "id": 93974, "title": "Handoff - AI Agent for Residential Contractors", "tagline": "Handoff makes you more money, saves time, and runs your residential contracting business with AI.", "body": "### **The Problem**\n\nThere are 1.2M+ residential contractors (remodelers, home builders, etc.) in the US. They are severely understaffed and overworked:\n\n* 40% of their time goes to paperwork instead of building.\n* They rely on pen & paper or outdated software.\n* The US needs 4.7 million new homes (and contractors need to keep up with that demand).\n\nhttps://www.youtube.com/watch?v=jd85wN1hhBo\n\n### **The Solution: Handoff AI Agent**\n\nHandoff is the AI agent that helps owners of residential construction businesses automate their back office with AI.\n\nHere are some of the things Handoff can do:\n\n* Generate accurate construction estimates from short project descriptions and files (blueprints, photos, videos).\n* Automatically create material shopping lists (with links to purchase).\n* Send invoices, accept payments, and issue consumer loans.\n* Build project schedules, subcontractor bid invites, daily logs, and more.\n\nHandoff takes on the roles of:\n\n1. Cost estimator\n2. Project coordinator\n3. Admin assistant\n\nThis reduces the operational burden of scaling a construction business by $500k+/year, at a price point of just $149/month.\n\n![uploaded image](/media/?type=post&id=93974&key=user_uploads/428748/c2abd311-42d3-4f56-aed6-87253717f18e)\n\n![uploaded image](/media/?type=post&id=93974&key=user_uploads/428748/69f03428-53c5-4f46-9def-875366b532d9)\n\n### **The Secret Sauce**\n\nHow did we build Handoff? In short, we became obsessed with creating the world’s most accurate API for construction costs and a knowledge base of construction logic.\n\nWe work directly with top suppliers like Home Depot and Lowe’s to integrate their catalogs into Handoff, giving our customers real-time pricing and inventory.\n\nWe’ve also trained Handoff on 10,000+ construction cost estimates we completed by hand while running a manual cost estimating service in our early days.\n\n![uploaded image](/media/?type=post&id=93974&key=user_uploads/428748/9349123e-4a79-47c3-a7b6-7cb7d0575a47)\n\n### **Send This to Your Contractor**\n\nAre you getting some remodeling work done?\n\nGet a free account on [Handoff](https://handoff.ai/) and generate an estimate for your project.

Developers can use our API to access up-to-date information on construction costs for workflows like construction estimating, procurement, and loan/insurance underwriting. The API can be either queried with GraphQL or easily integrated into any application with one line of HTML.**\n\n📚 **Backstory**\n\nAs wild as it sounds, the construction industry still uses actual books that are published once a year to track construction market pricing. I previously ran the data science team at CloudKitchens where I needed an API for tracking live construction pricing data--but instead of an API I had to deal with these cost books.\n\n![](https://t4207102.p.clickup-attachments.com/t4207102/24e83b10-e8f3-4b04-b043-a050c01c2eb1/image.png)\n\n📊 **Problem**\n\nConstruction costs have been extremely volatile over the last several years. For example, lumber prices skyrocketed 400% and then crashed in 2021. At the same time, the construction tech space is booming ($5B+ is invested annually), but it still lacks its own \"Plaid\" for mission-critical market pricing data.\n\n🛠️ **Our solution**\n\n1build has an easy-to-use API as well as a JavaScript embed widget that gives you access to live pricing data on 68 million construction materials, labor, and equipment anywhere in the US.\n\n🚀 **How it works**\n\nYou can either use our GraphQL API ([docs](https://developer.1build.com/1build-api-reference)) or JavaScript embed widget ([docs](https://developer.1build.com/1build-widget-reference/)) to integrate construction pricing data into your application. Sign up [here](https://app2.1build.com/public/register?signupType=SOFTWARE_DEVELOPER) to get your API key.\n\nHere are just some of the use cases for our data:\n\n* Your contractor sent you an estimate and you want to validate their quote vs market rates.\n* You're serving bank underwriters who need to check whether their client's construction loan application has an accurate budget.\n* You're working with insurance brokers who need to approve a quote for home repairs.\n\n![uploaded image](/media/?type=post&id=70854&key=user_uploads/428748/7736013a-63ee-4a2c-ae3e-72873fb8f515)\n\n**Features**\n\n⚫ Search or browse our catalog of 68 million construction items and assemblies localized to your project.

When I was younger, my mom worked at a telco. I’d regularly hear stories about projects that were delayed or over budget because of miscommunications or errors with contractors. Last year I met two friends in telco who were complaining about the same problems as my mom. Hearing that, I dug in to learn more, and was shocked to learn that not much had changed in the decades since then.

Today that takes months and a surveyor.

That documentation is still done by hand: schedule a surveyor, drive out, measure with a tape or a GPS rover, write it on paper, go back to the office and draw it. Then the next contractor does the same thing again, for their own pipe, in the same trench.\n\nOur average customer **waits 6 months** for documentation and spends around **$4M a year per German city** on it.\n\nAnd once the trench is backfilled, nobody can check whether the numbers were right. One person's reading, one moment, unrepeatable. That is why crews keep hitting lines that \"aren't there\".\n\n![uploaded image](/media/?type=post&id=114663&key=user_uploads/1260577/f446f4ae-943d-4c83-ba7e-c48b9220eca7)\n\n### **Solution ✅**\n\nThe crew films the open trench with a phone for about 10 minutes. Then:\n\n**Our SLAM engine** builds a metric 3D model from that video — no surveyor, no scanner, and it works without GPS in basements and house connections\n\n**Our vision engine** recognises the components — pipe types, diameters, fittings, couplings — and attributes them\n\n**Our agent** produces what the customer actually files: CAD/BIM, GIS, quantities, and invoice-ready numbers\n\n![uploaded image](/media/?type=post&id=114663&key=user_uploads/1260577/bbaddb8c-abbf-43ad-8866-025cde7bb93b)\n\nThe crew also talks while filming, and that goes into the record:\n\n> _\"There was a gas pipe crossing, so we had to lay this pipe approximately\\\n> 50 cm below it.\"_\n\nNo point cloud and no plan ever captures the _reason_ for a deviation — and once the trench is closed, it is gone for good. That sentence, anchored to the exact position in 3D, is the part nobody else has.\n\n**Where we are:** seven paid pilots in three months, the first converted to an annual contract, working with utilities and contractors on district heating in Germany.\n\n**Why now:** phones do metric 3D capture, reconstruction got cheap, and vision-language models read attributes rather than just detecting boxes. And the long game: construction robots are coming, and nobody holds the training data for what is underground.

Get in touch at [founders@line.build](mailto:founders@line.build)\n\n### **The Problem**\n\nWith buildings accounting for almost 40% of US GHG emissions, retrofitting for efficiency is essential to reduce emissions and load on the grid, but expensive. Over $80B of rebates, incentives and financing is available but hyper-fragmented across utilities, federal funds, grants, and green lending programs. Contractors are often responsible for helping consumers navigate this fragmented landscape - not only does their consumer demand it, but many sources of funding require it. This is leading to an increase in overhead, as they hire Ops teams and consultants to meet demand. Contractors that do not provide this service are seeing their conversion impacted, as consumers look to maximize savings. \n\n### **Our Solution**\n\nLine is a single source of truth for all available funding options. By providing a few pieces of information, such as project address and scope, contractors can easily access all available incentives and financing options available to their customer. Requirements are consolidated and distilled in a simple manner and we make suggestions that help contractors maximize savings for their customers. Maximized savings, means maximized conversion!\n\nOnce the customer is ready to proceed with the project, the contractor can leverage a common application to apply for all eligible programs. We remove the hassle of navigating multiple websites, printing documents, or mailing applications.\n\nOur platform is designed to be user-friendly, available in multiple languages, and accessible on both web and mobile devices. Additionally, we provide an API that seamlessly integrates with existing quoting tools, enhancing efficiency and convenience.\n\n![uploaded image](/media/?type=post&id=72550&key=user_uploads/1432654/02e79c39-4134-4f77-bff2-286ca21bbd57)\n\n### **Our Backstory**\n\nDasha and Steph have worked on payments and risk management for the last 10+ years at companies such as Airbnb, Plaid, Stripe, Asana, Gusto, and Google. We couldn’t think of a bigger risk than climate change, and wanted to find ways to help accelerate the transition to a greener and more energy efficient economy. We learned that cost is a big barrier to deploying technology such as heat pumps. We knew that funds such as utility rebates were available, but were surprised at how hard the process of discovering and applying for them is – so we decided to help solve that! \n\n![uploaded image](/media/?type=post&id=72550&key=user_uploads/1432654/96e73cbe-5f05-4084-b4bc-890df449174a)\n\n### **Ask: How you can help**\n\n* Connect us to contractors such as HVAC installers, residential solar companies, electricians or whole home electrification contractors to try out our pilot\n * _quick blurb to copy & paste:_ [Line](https://www.line.build/?utm_source=YCLaunch&utm_medium=post) is a new tool that creates a single source of truth for all available funding options for home energy efficiency projects.

For commercial real estate subcontractors, Trayd generates back office efficiencies with a platform that manages workforce attendance and payroll. For workers, Trayd offers instant access to their earned wages. Win-Win.\n\nWe are Anna Berger and Cara Kessler, the team behind @Trayd and we are on a mission to digitize construction payroll in order to power a better financial future for subcontractors and their workers.\n\n![uploaded image](/media/?type=post&id=73344&key=user_uploads/1435469/811e72a1-0fc1-4b73-ab24-27b7ed95567f)\n\n### 🚨**Problem**🚨\n\nWithin commercial real estate, demand for work is at an all-time high. In the last year, total construction spend in New York City reached $86BN and it keeps on climbing. That said, construction subcontractors are ill-equipped to handle the influx of work, with only 17% of them using digital tools to manage their back office. This lack of tech adoption is leading to work stoppages and high attrition, resulting in major revenue loss.\n\nTo make matters worse, construction employment still lags behind pre-covid levels. Of those that remain, highly skilled workers are choosing to leave the trades in search of more control over their cash flow, for example, gig economy jobs that allow them to work when they want and get paid instantly.\n\n### **🏗️ Our Solution** 🏗️\n\nTrayd is new type of construction payroll platform, designed to incentivize all key players. Through a closed loop system, Trayd tracks workers’ daily attendance in order to power real-time payroll automation. By merging time and payroll data into one system, subcontractors save tens of hours a week on manual back office work. As an added bonus, because Trayd authenticates attendance in real-time, Trayd can offer instant payment options to the workforce.\n\n![uploaded image](/media/?type=post&id=73344&key=user_uploads/1435469/5ed2d168-f70d-4752-b949-09d093ba8d81)\n\n![uploaded image](/media/?type=post&id=73344&key=user_uploads/1435469/92cdb561-b705-4aca-9ce1-c33f875435b9)\n\n### 📖 **The Backstory** 📖\n\nBorn into a construction family and close to the problems that plague subcontractors and workers on a daily basis, our team is excited to modernize construction back office operations while simultaneously offering financial tools and opportunities to subcontractors and workers.\n\n### **Asks 🙏**\n\n* Know anyone in the construction industry?

Take the San Francisco team we’re working with that just finished a major 3-year project. By the end of the project, they had a 2000-page plan that had changed hundreds of times, 2300 change orders, and thousands of bids, RFIs, and submittals going back and forth between the general contractor, developer, architect, engineers, and 93 specialty contractors. The team spent hours each week trying to find information across email, Procore, chat conversations, and document management systems.\n\nLook at all the folders one of our customers has for just 1 project!\n\n![uploaded image](/media/?type=post&id=73724&key=user_uploads/1393936/d805b330-519c-4775-a2c5-c6699a58a99c)\n\n**Not finding accurate information quickly can be detrimental to a project**\n\nMany teams waste time and hire additional people to sort through data and search for the answers they need, yet still mistakenly use outdated or incorrect information. A [**study**](https://www.constructiondive.com/news/contractors-lost-18-trillion-globally-in-2020-due-to-bad-data-new-report/606939/) by FMI found that “bad data” – including data that is inaccessible, inconsistent, or untimely  – **cost the global construction industry $1.85 trillion** in 2020. Operating off of outdated plans or missing information can lead to costly delays, expensive re-work, and in the worst cases can cause dangerous conditions for the crews on the ground.\n\n## **✨ Our Solution**\n\nConstructable is the central place to find any information and get questions answered about a construction project. We aggregate documents and communication from file management systems like OneDrive and Dropbox, construction management software like Procore and Autodesk, email, and chat apps and make it quick for teams to answer any question and find the relevant documentation.\n\n![uploaded image](/media/?type=post&id=73724&key=user_uploads/1393936/9318d182-f037-4d41-a7cd-f6f4a7a90581)\n\nConstructable makes it easy to:\n\n* Compare bids from multiple specialty contractors and see if they are missing key components in their bid\n* Find the most recent steel plan and highlight what has changed since the last revision\n* See RFIs that have been outstanding for more than 2 weeks and the contact information of the requestee\n* Find the change order that involved adding an additional wall to the lobby, link to the before and after plans, and list the difference in takeoffs because of the change\n* Get the schedule of all specialty contractors working the following week and which supplies are still on backorder for each contractor\n* Get data from the appliance manuals needed for maintenance teams once the project is delivered\n\n## **The Team**\n\n![uploaded image](/media/?type=post&id=73724&key=user_uploads/1393936/05c0d913-f492-43de-babd-97f415d5c860)\n\nWe spent the past 10 years working together at Appfolio (Nasdaq: APPF), where Emma was a VP of Product, John was a VP of Engineering, and Molly was a product growth leader.

It unifies jobsite capture, 3D building scans, estimates, and field documentation in one simple app.\n\nWe’ve grown to over 200 paying customers on the web over the last few months, and are now launching the mobile app so field teams can use the full product on site.\n\nZayne and Shelby are construction software veterans with a combined 10+ years building computer vision and spatial AI tools.\n\n**Meet Feldy:**\n\n\n\n**The Problem:**\n\nThe biggest problem in residential home services in 2026 is still remarkably simple: estimates do not go out fast enough to homeowners.\n\nAn estimate is the quote a homeowner receives explaining what work will be done and how much it will cost. Yet, if you call a window contractor, or painter, it can still take two or three days, often longer, to receive one. Over the last 8 months, my home became a test bed for remodeling projects, and this is one of the few truths that persisted. This problem appears in nearly every trade we encountered.\n\n_So why so long?_\n\nThe surprising part is that many of these estimates are not inherently complicated.\n\nConsider a typical window and door contractor. A sales representative drives to the property, walks through the home, identifies every window and door, photographs existing conditions, and asks discovery questions:\n\n* Do you want to replace the trim?\n* Should the opening change?\n\nCapturing this information can easily consume most of a one- or two-hour appointment. By the time the rep understands the property and records everything the office needs, there is _very little time left_ to actually sell the project. This is the primary reason quotes arrive days later, or require a second visit.\n\nFurthermore, existing software makes the problem worse.\n\nMost contractor tools have always been structured like digital forms. The software records what the estimator has already figured out, but it does very little to help figure out the job.\n\nThis is what led us to ask: what does this contractor world look like if the software recorded and figured out the job at once? Well, that’s Feldy.\n\n![uploaded image](/media/?type=post&id=110395&key=user_uploads/1494934/6bdd00aa-4517-41c6-897e-517110044d2b)\n\n**So how do we solve this?**\n\nInstead of requiring the person in the field to manually observe and organize everything, Feldy uses in-house computer vision and vision-language models to perform much of this _low-value work_: necessary technical work that consumes the majority of the job visit time, but creates little visible value for the homeowner.\n\nThe contractor _captures_ the property via photos/videos, lidar scans, or job walkthroughs (video and audio are combined). Feldy then interprets the capture and helps turn it into an estimate amongst a host of other workflow items such as inspection reports, proposals, materials lists, etc.\n\nThe entire thesis behind Feldy can be summed up as:\n\n_How do we remove the time-consuming thinking required from the estimator that creates little visible value for the homeowner?_\n\n![uploaded image](/media/?type=post&id=110395&key=user_uploads/1494934/060ca1ad-5038-40a5-868f-fb14eb04b164)\n\n**The Scale of the bottleneck**\n\nAngi’s list has estimated that American households undertake more than 700 million home projects annually.\n\nUsing 600 million estimates (aggressive case):\n\n* 600M estimates \\* 3.5 hours = 2.1 billion total labor hours\n* 50% spent on measuring, documenting, takeoff, and estimate construction = 1.05 billion hours\n* At $45–50 fully loaded cost = $47–53 billion in annual labor capacity tied up in that work\n\nIf Feldy reclaims 1–1.25 hours per estimate:\n\n* 750 million hours returned\n* Roughly $27–37 billion in productive capacity per year.\n\nFor the average home-services company, this is equivalent to reclaiming $50,000–$100,000+ in capacity each year, capacity that can be converted directly into more estimates, lower overhead, and higher revenue.\n\n**The Team**\n\nZayne and Shelby met at UC Berkeley’s engineering school nearly 10 years ago. For the last three years, they have worked side by side building technology for the construction and home-services industries.\n\nTogether, they previously took a construction-software company from zero to $500k ARR in months. \n\nThe pair is more excited than ever to build the next generation of software for home-service businesses.\n\n**The ask**\n\nIf you know anyone who works in home services, tell them about Feldy and ask them to download the app!\n\nSearch Feldy AI on [IOS ](https://apps.apple.com/us/app/feldy-ai/id6780327228)and [Android ](https://play.google.com/store/apps/details?id=com.feldy.app)app stores.\n\n* You can reach us directly at [**zayne@feldy.ai**](mailto:zayne@feldy.ai)\n* To learn more about Feldy visit us at our [feldy ai](https://feldy.ai/?utm_source=yc&utm_medium=launch&utm_campaign=feldy_launch_campaign_2026&utm_content=first_launch_post) website", "url": "https://www.ycombinator.com/launches/SiZ-feldy-field-first-ai-for-home-services-and-contractors", "votes": 22, "created_at": "2026-08-13T14:55:04.664Z" }, { "id": 79053, "title": "Aether - AI platform for rooftop solar", "tagline": "Aether is AI design and workflow software for solar installers.", "body": "**TL;DR**\n\n[Aether](https://aetherenergie.com/) offers an AI-powered end-to-end platform for rooftop solar installers.

Our fundamental mission is to make rooftop solar energy accessible and cheap throughout the world.\n\n![uploaded image](/media/?type=post&id=79053&key=user_uploads/1527633/561a67f7-4f40-419e-af7f-2ff7557ac5b7)\n\nFor rooftop solar to be deployed, it’s really up to solar installers. To us, the people who run these companies are our heroes. Last year we spoke to hundreds of solar installers and one thing is clear - they don’t have the tools to make them successful. We reimagined rooftop solar software from the ground up for them.\n\nAether _automates the boring stuff for solar installers using AI_.\n\n## **❌** The Problem:\n\nThe biggest problem in US rooftop solar is still solar soft costs. These are non-hardware costs associated with a solar project, and they amount to north of 60% of the total solar cost of an installed system! If you reduce this you create more demand for rooftop solar in the market = better outcome for our planet.\n\n**Contributors to high soft costs:**\n\n* **PV CAD Design teams still manually build rooftop PV site designs**. This is time-consuming and prone to lots of errors. Mistakes here mean re-doing plansets and permitting which can cost $1k - $2k extra.\n* **Almost all solar design tools are inaccurate in production and consumption modeling**. This is what tells rooftop owners “Is this the right investment for me?” Most solar tools were built as a sidekick for sales reps, with just enough basic estimates to sell a solar proposal. Consumers are smarter now and recent legal litigations are forcing better modeling to be done when selling solar.\n* **Dependency on multiple platforms:** Most solar companies use a software stack of 6 - 10 point solutions. Collectively the solution is dumb and creates chaotic workflows where deals get lost and project delays happen a lot. This is very expensive.\n* **Lack of project visibility across teams** causing lost sales deals, and project delays\n\nWe estimate $5k to $ 7k added soft costs for a typical rooftop project occurring because of the above.\n\n## **✅** Solution:\n\n**Aether is built to streamline the rooftop solar workflow end to end. Think Procore or Veeva but for Solar with an AI twist.**\n\nWith Aether, solar companies can rapidly generate PV site designs, sell using a beautiful PV proposal, and then manage it to installation in one simplified workflow.\n\nAether is made up of hubs that help specific roles in a solar installation company do their job, but more importantly, collaborate with other teams as needed with the help of AI.\n\n**Our two core innovations:**\n\n* We built an in-house computer vision model.\n* We also decided to build a mini fine-tuned model for solar.

Bidflow is an AI copilot that helps electrician companies sift through tedious documents and automate the repetitive work that goes into quoting a job.\n\nAsk: Do you know any electrical contractors? If so, introduce us at [founders@tryghostship.dev](mailto:founders@tryghostship.dev) or [book a demo with us](https://calendly.com/jessechoe10/demo-with-bidflow).\n\n# The Problem\n\nElectrical estimating - the process of figuring out how much an electrical construction project will cost is super tedious and can take anywhere from a few hours to months. Imagine reading through 500-page PDFs, counting hundreds of small symbols per page on 50 pages of complicated circuits, and manually entering thousands of numbers on slow, legacy software.\n\nElectrical estimators do this process everyday but manually, and most of the time, they lose the job by a small margin. Estimating is the only way electrical contractors make revenue, and they do it manually because one mistake can cost thousands of dollars and they need to be careful!\n\n# Our Solution\n\nBecause estimating is such a careful process, electrical contractors still do everything manually, especially because AI is hard to trust. That’s why we built Bidflow - an AI copilot for electrical estimating that serves as an assistant not a replacement.\n\nBidflow is designed with context to think like an electrician and most importantly, show the estimator “proof of work”, turning the estimators job more into reviewing the AI’s mistakes. We’re able to process all of your project documents and save you time in reading through hundreds of pages of fine print.\n\nBidflow also has the same features as the legacy softwares these estimators use, but it combines everything together, making it an all-in-one platform that also saves estimators time switching between the softwares.\n\n\n\n### Our Team\n\nWe decided to target electrical contractors because we both have family in the industry who’ve complained about how slow work has been. We then decided to go door-to-door in the Bay Area and got our first design partner.\n\nJesse (CEO, right) - **Top 1%** competitive coder in the US; **Jane Street** extern.

New data centers are being built left and right, meaning there’s a lot of electrical construction projects in the market.

Miss one item, and budgets blow up — every year, it costs the small European country of Sweden over $11 billion (according to the government itself) and the global industry _hundreds of billions_ every year. Estimators and PMs are the heroes who keep projects on track, but today they’re buried in manual work.\n\n**How Brickanta helps**\\\nOur AI reads and organizes project docs, flags missing items & compliance risks, and supports cost analysis, tendering, and planning. It’s trained on standardized building protocols (starting with the Swedish versions of the Eurocodes, soon more countries) and integrates the systems that construction already runs on, like MS SharePoint, Outlook, and Teams — helping teams work faster, catch risks earlier, and protect margins.\n\n🎥 YC Launch Video:\n\nhttps://www.youtube.com/watch?v=za8Ya5GxMRE\n\n\\*\\*Excited to support?\\*\\*\\\n👷‍♂️🛠️👷‍♀️ We’re officially launching this week with exclusive media interviews, first public customer story, new brand + website, and more.

This process is slow, tedious, and unreliable.\n\nErrors that are missed become exponentially more expensive to correct once construction is underway, causing massive project delays and budget overruns.\n\n---\n\n### **⚙️ The Solution**\n\nStructured AI is the **AI Quality Assurance platform.**\n\n1. **Proprietary Vision & Agents:** We trained a foundational vision model on **thousands** of engineering symbols to read plans like an expert.\n2. **100x Faster, 150% More Errors:** Our AI checks 100-page blueprints against 2,000 pages of building codes **in minutes.**\n3. **Cross-trade Checks:** Learns firm standards to detect inconsistencies across documents, drawings and Revit models, reducing cross-trade clashes before they occur.\n\n ![uploaded image](/media/?type=post&id=94607&key=user_uploads/1527607/252c0ccd-bd5b-4118-b05f-1f9767d981a6)\n\n\n---\n\n### **👷‍♀️ The Team**\n\nThe team is made up of **Oxford University–trained AI researchers** with deep experience building software tools for AEC and enterprise automation, having developed and scaled in-house AI tools at **Syska Hennessy Group**, a top US MEP (mechanical, electrical, plumbing) engineering firm. \n\n* **Brandon (CTO):** Authored papers for **NeurIPS** and **ChromaDB** (reviewed by Stanford's AI Lab) and created the first open-source **RAG chunking evaluation** framework.\n* **Raymond (CEO):** Built automation at **Goldman Sachs** and the **London Stock Exchange**; implemented an AI system at a £1B VC that increased deal flow 20×.\n* **Issy (COO):** First undergrad Director at Oxford's VC Fund, led investments later backed by a16z and Tim Draper; previously investment banking at **Greenhill.**\n\n### **🏗️ Why Construction Engineering?**\n\nBrandon started coding and making games when he was 12. At 17, a YouTube video he made demonstrating a fighter jet trained with deep reinforcement learning to dodge missiles went viral. This led to him being scouted by a US construction contractor to apply that same algorithm to MEP pipe routing optimization. He then spent the next six years, throughout high school and university, contracting and building AI tools for the construction and engineering industry. He later led innovation and scaled AI tools in-house at a top US engineering firm, ultimately spinning out with his team to form Structured AI.\n\nRaymond initially pursued architecture and engineering, but was talked out of the profession during an internship. Junior architects warned him about the extensive manual \"grunt work\" that defined their roles, a prospect that deterred him so much he switched his studies to Maths & Stats at Oxford. He now views his work freeing engineers from these very tasks as a full-circle moment, allowing them to focus on their passions.\n\n![uploaded image](/media/?type=post&id=94607&key=user_uploads/1527607/1e2f9415-f8f3-419c-92d8-0e007f9919b9)\n\n---\n\n### **🙏 Our Ask**\n\nIf you lead **mechanical, electrical, civil, or structural design teams** and want to automate documentation or QA workflows, we’d love to show you Structured AI.\n\n👉 Book a call: https://www.getstructured.ai/ \n\n📩 Contact: [info@getstructured.ai](mailto:info@getstructured.ai) ", "url": "https://www.ycombinator.com/launches/Obv-structured-ai-agentic-workforce-for-construction-design-engineering", "votes": 212, "created_at": "2025-10-14T19:17:28.011Z" } ] }, { "id": 30911, "name": "Helonic", "slug": "helonic", "former_names": [ "Articulate" ], "small_logo_thumb_url": "https://bookface-images.s3.amazonaws.com/small_logos/336d43aeb77b236c25b003848175a054e780ccbc.png", "website": "https://helonic.com", "all_locations": "New York City, NY, USA", "long_description": "We help construction teams eliminate rework, delays, and drawing confusion before construction starts.

Across solar farms, data centers, and beyond.", "body": "Hey everyone 👋 We're Jermaine and Yaojing, co-founders of Libra Robotics. **We'll present & demo at YC's F26 Demo Day!** If you're attending, we'd love to connect.\n\n**TL;DR:** Infrastructure faces rapid expansion and labor shortages. Today, robots struggle to scale to meet customers’ high-mix work needs. Libra builds AI that engineers robots for new tasks across embodiments. We go from each new infra task to field-deployable robots 10x faster. Today, our robots are working on solar farms and piloting in data centers. Contractors pay for completed work as a service, not robots.\n\n\n\n\\[A simplified walkthrough of how Libra’s AI takes a real data center customer's task from initial requirements to robotic deployment - autonomously designing, simulating, testing, and improving along the way.\\]\n\n**The Problem**\n\nInfrastructure has a labor shortage. Robotics has a scalability problem.\n\nUnlike factories, infrastructure work is high-mix: tasks, designs, and environments constantly change. Single-task robots need custom engineering per task; general-purpose robots need enormous data to become reliable. **Neither scales to thousands of changing tasks.**\n\n**Our Approach**\n\nInstead of building one robot that does everything, we build **reusable robotic capabilities and AI that engineers them into new tasks.**\n\nMany infrastructure tasks share the same physical challenges: handling heavy components, precise positioning, alignment, and fastening. We've built a common set of robotic capabilities around these operations, designed to work across different robots and installation tasks.\n\nOur hardware-agnostic AI selects the right robot configuration and tooling, reuses existing skills, and engineers what is missing for each new task, reducing the need for custom engineering.\n\nIt validates solutions in simulation, then autonomously designs and runs physical experiments on our in-house robotic testbeds, stress-testing solutions against real-world variability (such as unexpected obstacles, changing environmental conditions, etc.). When a test fails, the system **diagnoses the failure, recovers, and iterates autonomously** - without human engineers in the loop. Through **recursive self-improvement (RSI)**, it continuously refines its approach toward field-ready performance.\n\n**Every task adds reusable knowledge, making the next one faster and cheaper to automate.**\n\n**GTM & Traction**\n\n**We deploy AI-powered robot crews to perform infrastructure work**, starting with solar installation and data center electrical work, including prefab MEP and busway installation. \n\n**We're already beyond the lab:**\n\n→ **Robots already deployed** on real solar construction sites\n\n→ **Signed commercial agreements** for solar installation\n\n→ **Data center pilots underway** for MEP automation\n\nWe land with one high-value task, then expand into more work for the same customer. Our goal is to achieve 100 million hours of robotic work annually by 2031.\n\n![uploaded image](/media/?type=post&id=122276&key=user_uploads/3178817/7e72e897-d6d4-4ed6-a547-0f5889a68de0)\n\n\\[Libra’s robots in action on solar farms\\]\n\n**Who We Are**\n\nYaojing did her Stanford PhD on the exact problem Libra solves: one shared robotic platform with reusable skills that generalizes across construction tasks. She has worked with 40+ contractors and construction robotics companies.\n\nJermaine previously led a team to build and deploy autonomous agricultural harvesting robots from the ground up, tackling complex manipulation, precision harvesting, and multi-robot coordination in unstructured real-world environments. He brings end-to-end experience turning robotics research into reliable, field-deployed systems.\n\n**Our Ask**\n\nWe're looking for introductions to:\n\n* **Data center GCs, EPCs & Prefab contractors** interested in deploying robots for prefab MEP installation, busway installation, and other electrical fit-out tasks.\n* **Solar EPCs & installers** with upcoming utility-scale projects interested in robotic installation.\n* **Robotics engineers & researchers** working on sim-to-real, autonomous robot engineering, and multi-embodiment learning who want to build with us.\n* **Investors** who are interested in backing the robot workforce companies for AI era.\n\nKnow someone we should talk to?

Nobody in the industry wants another platform — they want what they already have brought together in one place. Alloovium is that unifying layer: it reads everything the project produces from the tools you already use, and turns it into cited answers you can trust and the documentation that moves the job forward — compliant with the builder's own management system, every answer cited to its source sentence, a human sign-off on anything AI-drafted.\n\n[**https://youtu.be/wVPJL3o8PzM**](https://youtu.be/wVPJL3o8PzM)\n\n**🚧 The problem**\n\nOn major projects, the record keeps losing: 80% of megaprojects blow their budget or schedule, and sums in dispute average a third of contract budgets. We think the root cause is hiding in plain sight — in the paperwork.\n\n**The root cause:** paperwork is a state in time — every document a snapshot of a project thats moving daily. The documents aren't a pile, they're a web: the safety plan leans on procedures; procedures lean on templates, registers and licences; and the tender made promises all of them have to keep true. Across every company delivering the job. People spend their days dragging the paper back to reality instead of moving the job forward.\n\n**The consequence:** one change means five documents to amend, and nobody catches the missed one until an auditor, regulator or client's lawyer does. In some jurisdictions: up to 25 years jail for directors and a $20M fine for the GC.\n\n**The cost of coping:** engineers who trained for years to build spend their days chasing paper instead. One tier-1 team is spending $2.5M and 40–50 people on a single 400-page submission of management plans — and that's before the project even starts.\n\n**The unlock:** a sleepless project sentinel, keeping watch on the documented rules, unlocking the experts to focus on the build.\n\n**🔨 What Alloovium does**\n\n* **Documents, Apps, Correspondence and Conversations centralised in the Project.** A singular place where the project becomes a reality.\n\n![uploaded image](/media/?type=post&id=105028&key=user_uploads/3047254/69afa2af-4a4e-4376-ad5e-186084b42ee4)\n\n* **Cited answers over every project document.** Click the citation, land on the exact source sentence.\n\n![uploaded image](/media/?type=post&id=105028&key=user_uploads/3047254/6687ff2d-1620-404b-b4a9-a6f8a8fd5aae)\n\n* **Routines.** Build repeatable workflows that are triggered by on-site events to always stay ahead of the game on your paperwork.\n\n![uploaded image](/media/?type=post&id=105028&key=user_uploads/3047254/ec46815c-e232-43eb-a583-ec74c80f25ff)\n\n* **Drafting from the project itself.** Call transcript to a formatted and actionable document in minutes, with AI-authorship tracking, a human still refines and reviews it.\n\n![uploaded image](/media/?type=post&id=105028&key=user_uploads/3047254/503df904-c919-46e3-9e31-c3e2c768db67)\n\n* **Continual compliance sweeps** against the builder's own IMS, clause by clause.

We’re David and Michael, co-founders of FlowManual.\n\n**What FlowManual is**: AI preconstruction for General and MEP contractors, executing projects while cutting risk. \n\n**TL;DR:** Construction contractors waste hundreds of hours monthly on manual tasks, sifting through 500-page PDFs only to miss fine print that can cost tens of thousands. FlowManual automates the back-office work before and during construction, so teams can reliably secure and complete projects faster than ever before.\n\n\\\n\\\n**The Problem:**\n\nMeet Jeremy. He’s a project manager at a mid-sized contractor, and his job is to secure projects and then make sure the company doesn’t lose money on already thin margins.\n\nA bid invite lands in his inbox. To put together one number his firm can send in, Jeremy has to read thousands of pages. A 400-page project manual, drawings, insurance, spec sections, and so much more. Buried somewhere inside all this print is a line that can ultimately decide whether this job makes or loses money. From a liquidated-damages clause to a scope item sneakily handed to the mechanical contractor, if Jeremy misses it, it’s a $5K-$10K mistake.\n\nJeremy’s got one week, three other bids on his desk, and no way to read all of it as carefully as he’d like. So he reads what he can and sends in a number.\n\nSay he wins. A change in the signed contract by the General Contractor or a sneaky difference in vendor pricing costs the company thousands after the fact. Every step of the way requires hundreds of pages of reading and referencing done under a deadline. And Jeremy does this for every job.\n\n**The Solution:**\\\nFlowManual automates these historical workflows that contractors run on, allowing teams to submit bids and complete projects faster than ever before. Here’s a couple major features:\n\n* AI Takeoffs from drawings\n* Drawing comparisons / overlay\n* Bid leveling\n* Contract Review\n\nOur software doesn’t do the job for you, but it works alongside you to reduce time spent and mistakes made.\n\n**About Us:**\\\nMichael and David were college roommates and engineers at Harvard. When renovations for a heater in our dorm took 6 weeks, we poked at the problem, realizing it stems from a larger issue. Through hundreds of conversations with professionals, we found an industry that ran on file cabinets, Excel, and page-by-page manual review.\\\n\\\n**Our Ask:**\n\n* **Know anyone in construction?** Connections to anyone in the industry, including on the legal and tech side, is greatly appreciated.

Engineers send it work the way they'd message a teammate, and it works across every workflow and tool the firm runs on, from CAD design and calculations, to reports and full plan sets. Firms using it today have decreased average project times by more than 75%.\n\n\n\n### How Gradon Works\n\n* Message it like a teammate. Type or talk to it, or share your screen and walk it through a problem. It takes the task from there.\n* It works the firm's way. Before Gradon ever touches a project, a firm brain is built, that learns the firm's past work and standards, so everything comes out just the way their team would do it.\n* It works inside their tools, from CAD design, to analysis software, and anything in between. No new system to move into.\n* Engineers stay in charge. Every deliverable comes back for review, and nothing changes until the engineer approves it.\n* Every discipline. Civil, structural, MEP, architecture and more.\n\nWe're also each firm's AI partner, not just another piece of software. We fly out and work one-on-one with each firm's engineers until they're getting the most out of it. After that, we continuously host office hours, lunch-and-learns and more, to make sure firms always stay on the frontier.\n\n### Why Now\n\nAI is the biggest change to engineering since CAD. The demand to build has never been higher, and the number of engineers can't keep up. The next great engineering firms will be the ones where every engineer has Gradon behind them.\n\n### Who We Are\n\nWe've known each other since kindergarten.\n\n* Nour (CEO) studied Mechanical Engineering at Berkeley and worked as a mechanical design engineer. Before startups, he played professional academy soccer for the San Jose Earthquakes for 7 years.\n* Yousef (CTO) graduated high school at 15, then earned a Bachelor's in EECS from Berkeley and a Master's from Stanford. He previously built FPGA infrastructure at Apple and worked on chip design at AMD.\n\n### Our Ask\n\n* If you run an engineering firm, book a demo today to see how Gradon can transform your firm to become AI-native.\n* Intros to owners and principals at civil, structural, MEP or architecture firms.

A step change is needed. Marengo is needed.\n\nTo customers, we’re **_the engineering firm for accelerated data center development_.** Internally, we have developed AI-native tooling designed for in-house use by professionals. These tools are:\n\n* **Physics-informed** - grounded in reality\n* **Deterministic** - the same specs will produce the same designs)\n* **Validated** - validated by our professional in-house engineers\n* **Data-driven** - we parallelise concept design generation, producing a virtually unlimited number of variations; we then run simulations to determine the best fit\n* **AI-native** - AI agents act as junior engineers accelerating manual processes so our professional engineers can focus on validation\n\n**How it works:**\n\nA customer gives us their plot of land; we leverage their heritage and requirements to deliver validated designs in **half the time** and **half the cost.**\n\n**Who We Are:**\n\n**Emil Ares** - Founded first company at 16, making six figures.

We’re proving the technology today by building large-scale infrastructure on Earth – utility-scale solar farms and hyperscale data centers. Our first machine, Cosmic-1, has already installed tens of thousands of solar panels in the field and more than doubled the productivity of traditional crews.\n\n \n\n**❌ The problem**\n\nAfter working at NASA JPL, SpaceX, and Relativity Space, we believe rockets are no longer the limiting factor to space exploration and that the first humans will land on Mars by 2034. **The new bottleneck is construction**. We won't be sending thousands of construction workers to Mars to build the energy, compute, and housing needed to sustain even a small city. **It has to be built by robots that don't exist yet**.\n\nOn Earth we have a similar problem - **we’ve lost the ability to build**. Construction productivity has declined for 50 years while manufacturing and agriculture became 10-15x more productive through automation. **The missing technology is robotic manipulation for the tasks still done by hand**: lifting, placing, fastening.\n\nMeanwhile, there is a generational infrastructure buildout happening right now. **$7 trillion** is going into AI data centers, power, and compute over the next six years, **more than the Apollo Program, Manhattan Project, and Interstate Highway System combined**. 40% of US data center projects are running behind schedule, and the skilled labor shortage is the #1 cause. \n\n**🤖 What we've built**\n\nCosmic-1 is a 10,000 lb autonomous robot capable of heavy-lift manipulation. In solar, it picks up 90 lb panels and places them onto racking with millimeter precision in any environment: 100-degree heat, freezing rain, snow, and dust. It seamlessly integrates into existing construction processes. Across tens of thousands of cycles it has more than doubled the labor productivity of solar installation, on some of the largest solar projects in the US.\n\n![uploaded image](/media/?type=post&id=106899&key=user_uploads/522502/bb5f86ec-a23b-4ffd-a173-87f36ce6fb1c)\n\n**👬 The Team**\n\nWe come at this problem from two angles. James (CEO) grew up on construction sites, then spent his career bringing robots to the field with Built Robotics and Autodesk Research. He learned you don't change the oldest industry in the world by disrupting it; you earn your way in by giving crews better tools.\n\nLewis' (CTO) life ambition is to build a city on Mars. His work at NASA, SpaceX, and Relativity Space spans rocket engines, launch vehicles, satellites, space stations, and, yes, Martian robots. When it became clear the space industry was well on its way to Mars, he went looking for the construction robots. When he didn't find them, we started Cosmic.\n\nWe’ve brought together a team of industry experts with experience building robots, rockets, drones, self-driving cars, humanoids, and nuclear reactor operations. We know what it takes to get a machine to show up day-in-day-out on the jobsite.\n\n![uploaded image](/media/?type=post&id=106899&key=user_uploads/522502/87f30a8e-6f83-490e-8bef-04225d1a525e)\n\n**🚀 What's next**\n\nWe're scaling in solar, taking Cosmic-1 into data center construction, and working with NASA on lunar construction robotics.

Of the $2.2T in annual US construction spending, $150B is wasted due to a lack of subsurface knowledge. All construction starts from the ground up, and more often than not, unexpected assets underneath the surface will hold a construction project back. Whether it's an unknown utility line, unexpected rock layer, or old foundation that wasn’t on any design map, the costs of delays from underground conflicts quickly add up. \n\nTake utility strikes, when an excavator hits an active utility line. For every dollar spent on the explicit repair cost of that utility line itself, the contractor loses an additional $30 per repair-dollar in project delays, insurance claims, idle work crews, and increased insurance premiums. For a hyperscale project such as data center construction, a single day of delay can cost the cloud-provider up to $14 million dollars for that single day.\n\nIn metropolitan areas, maps are incomplete at best and none create a unified picture of critical infrastructure, making excavation especially dangerous when natural gas or electric lines are broken.\n\nEnter SubVysion. We’ve built a fleet of autonomous rovers carrying ground-penetrating radar and other sensors that create a centimeter-accurate map of subsurface infrastructure. Our hardware is the first and the best to map the entirety of US infrastructure. Using our rovers, we comprehensively map construction sites, city streets, and even larger indoor buildings, at 100x better granularity and 10x the speed (with a single rover) compared to our competitors. We process vast amounts of data using machine learning and agents, and output that data into an easy-to-understand 3D scene. \n\nWho are we? Maxwell Stone was an early ML engineer at Roboflow (YC S20), and Wenson Tang built the world’s smallest and cheapest LiDAR-capable drone for adverse environments. We both studied computer science at the University of Pennsylvania. Together, we’re building SubVysion to map the entirety of America’s subsurface infrastructure.\n\nWe’re currently on job sites in Philadelphia and Texas, helping our first market of utility contractors save hundreds of thousands of dollars every year. We’re soon to expand our mapping services to municipalities and energy providers as we scale up our rover fleet and capacity!\n\nIf you’re in the energy, infrastructure, or hyperscale construction world, we’d love to hear from you at [founders@subvysion.com](mailto:founders@subvysion.com)!", "url": "https://www.ycombinator.com/launches/Sys-subvysion-preventing-150b-is-wasted-construction-spending", "votes": 7, "created_at": "2026-08-19T23:30:02.157Z" } ] } ]
