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 work from out-of-date code and is not jurisdiction-specific.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.

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.

Submitting tickets takes a lot of time and distracts project managers from higher value work.\n2. Making sure tickets don’t expire is also necessary, so contractors avoid a ‘down day’ (a day where they can’t work, due to an expired 811 request). \n\nWith 43M tickets submitted last year by tens of thousands of contractors, this is not a small problem.\n\nSo we decided to fix it.\n\n### We’ve made handling locates a breeze for contractors\n\nhttps://youtu.be/Y04NyOXGt2o\n\nWe built Clad Locates to make it fast and easy to submit and track 811 tickets.\n\n1. **AI-driven narratives -** We use AI to eliminate the most time consuming part of submitting a ticket, writing a ‘narrative,’ (to describe the path that a contractor will excavate.\n2. **Bulk Submission -** Clad connects with the state 811 systems to submit tickets automatically, 1 ticket at a time or 15 all at once.\n3. **Automated Tracking -** We get data from the state 811 systems to build an automated automated tracker to monitor when areas are ready to dig, and when tickets will be expiring.\n4. **Expiration Notifications** - To prevent ‘down days,’ Clad notifies contractors when tickets are expiring and need to be renewed.

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. I’m building Clad to change this status quo._\n\n_I’m excited to build Clad because today, it remains too hard to build new things.

This is because the vast majority of homes in the US are still heated by burning dinosaurs in a gas furnace. Fortunately, heat pumps are a proven and mature technology to transition buildings to clean, renewable electricity.\n\nA heat pump is like an air conditioner that can run in reverse, both heating and cooling your home. Traditional air conditioners take heat from inside your home, transfer it into refrigerant, and exhaust it outside. Heat pumps have a special valve that allows them to do the opposite, transferring heat from outside your home to inside. They’re able to comfortably heat your home even when it’s incredibly cold outside. Because heat pumps move heat rather than generating it, they are mind bogglingly efficient - with efficiencies up to 400%! Not only are they better for the planet, but they can save you money on your energy bills.\n\nMost homeowners can replace their existing furnace with an efficient heat pump system today. They’re also a great way to add air conditioning to homes that previously didn’t have it.\n\n**Why don’t more homes have them?**\n\nCost is the largest barrier to heat pump adoption. Installing a heat pump system in a typical American home can cost $15-30k! At these prices, gas furnaces (which typically cost dramatically less) sadly remain the default choice.\n\nHowever, heat pumps are extremely common in the rest of the world. In Australia, a homeowner would pay around half the price for a similar system!\n\nMore than half of the cost for a heat pump in the US comes from installation. Fortunately, this is something that we are uniquely positioned to tackle. Helios is installing heat pumps in the US for a fraction of the cost.\n\n![](https://lh4.googleusercontent.com/6v-jet006MWaOi_8RCCUMCvrHgP4cVUol7e9z2qKPGg8Rd2RD3rDo5Ta2r7wAW_NCXZQD7BUcW4781cwNrXn2S6VrHCy_YZRVnQ9nWWSzLCbBM5SsAwtH-8P6lpoCrrWOFu65ClNoYATorVxLTHc2g)\n\n**Who are we?**\n\nJeremy is a repeat Y Combinator founder and spent 10 years designing and building heat pump systems. Shreyas is a former rocket propulsion engineer from Blue Origin and SpaceX, with experience dramatically decreasing the build time of complex rocket engine assemblies. \n\nWe’re applying these skills to the large-scale deployment of low cost heat pumps. We’re simplifying the installation process to enable non-specialized labor (think car mechanics or plumbers) to install these systems.  Prefabrication and kitting mean that the right tools and parts are staged for each part of the installation, and our technicians spend less time at the job site. All of these things translate into dramatically cheaper heat pumps for our customers.\n\n**Our ask**\n\nSign up for a heat pump installation with Helios.

It uses refrigerant and a compressor to move energy to and from your living spaces. Residential heating makes up 10% of US energy use, and heat pumps are the best option for shifting this segment from fossil fuels. Heat pumps can also save homeowners on their monthly utility bills vs heating with natural gas, propane, fuel oil, and electric resistance. And thanks to the popularity of vapor injection systems, heat pumps now work well even in the cold climates of the Northeast.\n\n### **The Problem**\n\n* The homeowner experience sucks because the integration of thermostat, heat pump equipment and air quality systems is terrible. (Nothing works together well, the best thermostats are not fully compatible with efficient heat pumps.)\n* The process of getting a heat pump is painful, including finding a trustworthy contractor, sorting out financing, and wading through rebates\n* Contractors struggle with installs because of the difficulty of properly sizing the system, and understanding if your duct work is compatible with a heat pump\n\n### **The Solution 🔥**\n\nElectric Air is a full software and hardware solution:\n\n* Smart thermostat with PM2.5 and CO2 monitoring that triggers whole-home HEPA filtration and fresh air intake \n* Thermostat algorithm uses grid, weather and time-of-use rate plan signals to reduce monthly utility bills\n* A more powerful air handler and contractor software allows for more ducted installs\n* A beautiful outdoor condenser means you don’t have to hide this device in an alley\n* Seamless online sales experience - homeowners can order the system from the Electric Air website and get connected with financing, rebates and a trusted contractor\n\n### **Questions?**\n\nShoot me a message at [chris@electricair.io](https://mailto:chris@electricair.io)", "url": "https://www.ycombinator.com/launches/IBA-electric-air-tesla-for-heat-pumps", "votes": 39, "created_at": "2023-03-02T21:07:30.661Z" } ] }, { "id": 28823, "name": "Craftwork", "slug": "craftwork", "former_names": [], "small_logo_thumb_url": "https://bookface-images.s3.amazonaws.com/small_logos/a808b8722de9d2ecbb9fc19cae6ba864f6358f23.png", "website": "https://craftwork.com/", "all_locations": "Charlotte, NC, USA", "long_description": "Craftwork is a full-service home painting company that uses software to dramatically improve the homeowner and operator experience.", "one_liner": "Digital-native home painting franchise", "team_size": 50, "industry": "Real Estate and Construction", "subindustry": "Real Estate and Construction -> Construction", "launched_at": 1689608644, "tags": [ "Proptech", "Home Services", "Home Automation" ], "tags_highlighted": [], "top_company": false, "isHiring": true, "nonprofit": false, "batch": "Summer 2023", "status": "Active", "industries": [ "Real Estate and Construction", "Construction" ], "regions": [ "United States of America", "America / Canada", "Remote", "Partly Remote" ], "stage": "Early", "app_video_public": false, "demo_day_video_public": false, "app_answers": null, "question_answers": null, "url": "https://www.ycombinator.com/companies/craftwork", "api": "https://devasheeshg.github.io/yc-api/batches/summer-2023/craftwork.json", "year_founded": 2023, "city": "Charlotte", "country": "US", "linkedin_url": "https://www.linkedin.com/company/craftworkhome", "x_url": "", "fb_url": "https://www.instagram.com/craftworkpaint/", "cb_url": "https://www.crunchbase.com/organization/craftwork-be22", "github_url": null, "logo_url": "https://bookface-images.s3.amazonaws.com/small_logos/a808b8722de9d2ecbb9fc19cae6ba864f6358f23.png", "app_video_url": null, "dday_video_url": null, "company_photos": [ "https://bookface-images.s3.us-west-2.amazonaws.com/attachments/bb1fa629a28388bfe2035c893893fca712a7f883.png", "https://bookface-images.s3.us-west-2.amazonaws.com/attachments/83c2ef93e35eed99498b6f87c14976dadf6be198.png" ], "primary_partner": { "name": "Gustaf Alstromer", "url": "https://www.ycombinator.com/people/gustaf-alstromer" }, "founders": [ { "user_id": 193855, "full_name": "Tim Griffin", "title": "Founder/CEO", "founder_bio": "Tim is an active angel investor and two-time YC founder.

We then deploy trained, full-time employees to paint our customers’ homes.\n\n**The Problem**\\\nToday, it’s hard for homeowners to locate and hire home service providers, because contractors don’t use technology and rely on outdated employment models to operate their businesses.\n\nAs a result, the process for homeowners to complete any home project is riddled with challenges - from tediously searching for a reputable contractor, to coordinating multiple walkthroughs of their home, reviewing quotes, selecting a provider, agreeing to terms, scheduling the work, and enduring price and timeline changes before the work is finally completed - each step is frustratingly manual, unpredictable, and outdated.\n\n**The Solution**\\\nAt Craftwork, our coupling of a vertically integrated business model with best-in-class software allows us to deliver an unparalleled experience to homeowners.\n\nOur unique approach puts homeowners in control - from getting an estimate online with transparent pricing, to scheduling their projects and exploring our color selection tools, to meeting the team that will paint their homes and understanding what to expect when we arrive - we’re establishing a standard of transparency, accountability, and trust that simply can’t be matched.\n\nAs homeowners we’ve experienced first-hand just how difficult it can be to hire quality contractors.

We’re on a mission to give everyone on a construction project the information they need at their fingertips to deliver a project safely, accurately, and efficiently.\n\n## **🧨 The Problem**\n\n**Construction teams are spending too much time digging through data spread out in many places**\n\nConstruction projects are complex and constant change means a single project will have a huge amount of documentation. 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. We loved supporting the businesses that provide millions of people with exceptional living and workplace experiences and we’re excited to bring our experience to empower today’s builders to construct tomorrow’s communities.\n\nMolly has first-hand experience in the world of construction.

By linking directly to emails and texts, Karmen captures and organizes project updates, letting owners and general contractors automate time-consuming documentation tasks. Project managers can **save around 3 hours per day** from searching through 100s of emails and uploading to multiple construction management tools such as Procore.\n\n### **The Problem: Project Managers Spend Hours on their Emails**\n\nConstruction project managers receive hundreds of emails daily, many from subcontractors. These emails often include:\n\n* **Invoices**: Billing for completed work or materials.\n* **RFIs (Requests for Information)**: Requests for clarification on project details or specifications.\n* **Change Orders**: Requests for modifications that impact project scope, schedule, or cost.\n\nSubcontractors often send emails or texts and are reluctant to adopt construction management software to submit these requests. As a result, project managers spend hours reading emails and entering data into platforms such as Procore.\n\n### **The Solution: Automate these Tedious Tasks with AI**\n\nKarmen lets project managers link their emails and construction management software (e.g. Procore) to do the following:\n\n* **Data Entry**: Automating the manual process of entering details from correspondence, such as invoices.\n* **Project Matching**: Match emails to the relevant project and subcontractor.\n* **Real-time Updates**: Notify project managers of subcontractor updates that may affect the project schedule scope. i.e. a potential change order.\n\n### **Demo**\n\n\n\n### **About Us**\n\n![uploaded image](/media/?type=post&id=85372&key=user_uploads/2190507/ccc2d86b-7c9a-4c1e-9af4-00f660cc63c4)\n\nJonas managed logistics as a **commodity trader at IXM**.

We free up time for supes to do what matters most: keep projects on time and under budget.\n\n### The Problem: Documentation sucks\n\nImagine spending half your work day doing your actual job…and the other half _just writing down_ what you did. That’s the reality for 210k+ construction superintendents (or supervisors, foremen, PMs, etc.) across the USA. \n\nProject management tools like Procore and ACC have dramatically increased documentation requirements: supes are spending up to 3 hours a day creating documents for compliance, regulation, and to keep various stakeholders informed. This is on top of their actual job, which is to quarterback construction projects and manage safety, quality, timelines, and more.\n\n**Fresco creates documents in minutes, not hours.** By the time supes walk back to their trailers at the end of the day, all of their documents are already waiting for them.\n\n### The Solution: AI scribe\n\nToday, most supes already walk around job sites with their phones, taking photos or brief videos to capture problems or observations on site. But, at the end of the day, they do the very manual work of matching photos with their paper notes to create detailed “punch lists” or logs.\n\nIn Fresco, supes simply narrate over videos they take on site. For example, they might point the camera at a corroded beam and say something like “The beam in the southwest corner of room 134 is corroded and needs replacement by Alex.” Fresco pulls out this action item along with a picture of the beam so Alex can get the job done. **Supes who use Fresco complete their notes, on average, 90% faster.**\n\n![uploaded image](/media/?type=post&id=85005&key=user_uploads/210149/97e3a8cb-bacc-4f5e-847f-63832a6fc08a)\n\nIn this video, you can see how a supe and a project manager voice over a school refit we worked on. **Normally, creating the final report takes 2+ hours. Fresco uses the info captured on the walkthrough and creates the report in less than a minute.**\n\n \n\nFresco offers one-click integrations with Procore and ACC, so if supes need to enter their data there, they can easily do this without ever leaving Fresco. We’ve worked on sites that are using _both_ Procore and ACC, and Fresco saves supes hours they’d otherwise spend double-entering notes.\n\n### About Us\n\n[Arvind](https://www.linkedin.com/in/arvindveluvali/) - I got my BA + MS from Brown, and started my career in synthetic biology at NASA. After starting and selling a political tech company, I dove into the startup world, first in VC, then product, and most recently in sales + ops at an AI company.\n\n[Akhil](https://www.linkedin.com/in/akhil-climate/) - I received my BA + MA from Johns Hopkins, and worked on generative AI “before it was cool” at MIT and various startups.

Traditional BIM tools like Revit or AutoCAD aren’t built for AI-first workflows and often lack customizability that MEP and production homebuilders need to accomplish their workflows.\n\nWe can handle complex nested design options, complex calculations and layouts, and do auto documentation.\n\nFor MEP engineers:\\\n\n\nFor production homebuilders:\\\n\n\n### **😩** The Problem\n\nArchitects & engineers are talented, but the tools they use (like Revit) to draft homes and buildings are from the early 90s. The tools are clunky and slow to iterate in. This means that the iteration process is slowed down and leaves less time for filling in important construction details at the end.\n\n### **👌** The Solution\n\nArchiLabs is building a BIM tool from the ground up built for humans and agents to collaborate. We are starting with large homebuilders and MEP engineers because existing tools underserve these markets.\n\n### **🤠** The Team + Backstory\n\n![](https://lh7-rt.googleusercontent.com/docsz/AD_4nXd4XjIwSrSBtz4Vr7WA4JTko_Rwwz7JtCAeAJ3s4_EMUhcO1NIk790MSpsk54XJ39sF4NblVBJ9YRyqPlOjXleWeA04SewMCO9Q_RZLZ6XZXfv1t_eXhn4yqhnoVFbZlQfniBLBwg?key=sjQEh1jkB355E5fZmtO42GBG)\n\nWilliam graduated with a degree in computer science from Carnegie Mellon, then went on to work at Facebook. He realized his passion was the built world and set out to build homes from scratch in Texas where he experienced this frustration first hand. He then set out to build his own CAD tool.\n\nBrian graduated with a degree in ECE from Carnegie Mellon and went on to run a YC-backed tech-enabled homebuilding factory. He had a lot of frustrations with the architectural back-and-forth, primarily stemming from the limitations of existing tools. He then went on to build and sell an AI transcription startup.\n\nBrian and William met back up, sharing the same vision for reimaging the construction design experience and eventually taking on Autodesk, the $60B industry-leader.\n\n### 🙏 The Ask\n\nMore beta testers!

This is time-consuming and prone to human error, which can lead to tens of thousands of dollars in losses per project. It bottlenecks builders and suppliers from winning new contracts as they’re bogged down with the tedious process of bidding. There are massive manual estimation and bidding teams in-house and outsourced.\n\n# **Our Solution**\n\nWe're bringing construction blueprints into the present with artificial intelligence. Bild AI ingests blueprint files and applies computer vision models and large language models to calculate detailed material quantity and cost estimates for flooring, doors, hardware and more. Our first clients are using Bild AI to bid on 10x more projects, with confidence in the accuracy of the estimates. This is just one application of blueprint processing that our clients use today, but our vision extends to permitting and architecture checks.\n\n![uploaded image](/media/?type=post&id=87575&key=user_uploads/1759634/96a6ca22-fda3-4175-88f2-e41afa960a10)\n\n# **We are \\[Housing|Software\\] Developers**\n\n[Puneet Sukhija](https://www.linkedin.com/in/puneet-bild/) built his first house at 16 and has since overseen hundreds of construction projects, experiencing firsthand the frustration of working with complex blueprints.

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.

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.

Takeoff is the process of measuring and quantifying materials from concrete plan sheets. Rudus identifies every concrete structure (footings, walls, columns, slabs), pulls in related details, and eliminates hours of manual quantity calculation.\n\n**Ask:** If you know anyone in construction, we would greatly appreciate a warm introduction. Concrete-specific would be even more amazing. We would also love to talk to anyone who has built computer vision models.\n\n**Launch video**\\\n< >\n\n**The problem:**\n\nConcrete subcontractors are the backbone of every building, and their estimating workflow hasn't changed in 20 years . A senior estimator opens a PDF, manually traces every footing and grade beam, then hand-builds an Excel spreadsheet with 300+ line items- volumes, formwork, rebar by bar size with lap splices and development lengths. One bid takes 20 to 40 hours. Most firms have just a few estimators. That means they physically cannot bid on most of the work available to them. \n\nThe software incumbent in this trade hasn’t been updated since 2020. Past that, every AI takeoff tool on the market was built for GCs and treats concrete as one checkbox. None of them expand rebar assemblies. None of them compute development lengths. None of them output quantities the way a concrete estimator actually prices work. We built Rudus for this trade and only this trade. \n\n**Solution**\n\nAn estimator uploads their structural PDFs. Rudus auto-classifies every sheet (foundation plans, section details, footing schedules, frame elevations) and routes each to the right processing pipeline. Computer vision detects concrete elements across the drawing set and follows cross-references across sheets to resolve dimensions and detailing, catching elements that plan-only tools always miss. Each element gets expanded into full assembly line items: concrete, formwork, and rebar with all the calcs an estimator would normally do by hand. A typical foundation package goes from a handful of assemblies to 80-120 priced line items. The estimator reviews, overrides where needed, and exports straight into their existing workflow. We cut takeoff time by 80% and help estimators bid 3-5× more projects without adding headcount. From plan upload to bid package, every part of the workflow gets faster. \n\n**How we got here**\n\nSahil and I were engineers at Amazon and Airbnb respectively. We are both from Cupertino, CA and have been best friends since high school, always talking of starting a company together. Sahil took a construction management class and realized estimation workflows hadn't changed in decades. We started cold calling, walking into offices, showing up at job sites, and everyone told us the same thing: slow estimation is the biggest bottleneck in their business, but every new product they've tried has failed. We quickly realized that the reason those tools failed is a lack of trust. Estimators stake million to billion dollar bids on these numbers, and they won't trade their workflow for a black box. We took a different approach: software that accelerates their current workflows rather than replacing it by forward deploying our product into their current estimation workflow. The response from the industry was overwhelmingly positive, and we now ship weekly to estimators with decades of experience.

It answers the calls your office misses, books the appointment into your existing schedule, and then keeps following up on new leads, open estimates, and past customers until they book. **More of the leads you already pay for turn into jobs.**\n\n\n\n### **The Problem ❌**\n\n**Home service companies spend heavily to make the phone ring, then lose a chunk of that revenue before a technician ever shows up.**\n\nWhen the office is busy or closed:\n\n* After-hours and overflow calls go to voicemail\n* New leads sit for hours before anyone calls back\n* Open estimates never get a follow-up\n* Past customers are never reactivated\n* CSRs work callback lists by hand\n* Post-job happy calls happen only when someone remembers\n\nThe expensive part, generating demand, already happened. **The hard part is turning it into booked work.**\n\nMost tools fix one piece. Answering services take messages. VAs and extra CSRs add capacity, but they cost a lot to scale and rarely cover 24/7. Generic AI receptionists answer the phone and stop there.\n\n### **Solution ✅**\n\n**Part 1: AI receptionist and after-hours answering, 24/7**\n\nWhen your office can't pick up, CentralComs does. It answers after-d calls, figures out what the customer needs, qualifies the lead,answers routine questions, and **books the appointment into the schedule you already use**. It handles confirmations and reschedules, and it hands off any conversation that needs a human.\n\n![uploaded image](/media/?type=post&id=114503&key=user_uploads/1562583/82afad82-dec9-4460-b4f4-71c18fb5e736)\n\nIt works alongside the systems your team already uses, so you don'tont office gets 24/7 capacity without another hire.\n\n**Part 2: Automated lead follow-up and customer reactivation**\n\nBooking the first call is only the start. CentralComs keeps working customer hangs up:\n\n* **Speed-to-lead** follow-up on new inquiries\n* **Follow-up on estimates** that haven't closed\n* **Intent gauging**: ready to book, still deciding, or no longer inter\n* **Lead nurture** sequences\n* **Appointment reminders** and confirmations\n* Post-job **happy calls**\n* **Past-customer reactivation** and recontact for future service\n\n![uploaded image](/media/?type=post&id=114503&key=user_uploads/1562583/0331287a-0195-4998-ac9a-ef4b065e3052)\n\nNo CSR has to remember every callback, open quote, and old customer the agent more context on your services, business rules, and customers, so it handles more routine communication over time and passes the judgment calls back to your team.\n\n### **Our Team**\n\nWe're Kyle and Kevin, former UC Berkeley students and longtime AI builders. Kyle previously built and scaled an AI facility-management platform to **$600K ARR**, used by teams at **NVIDIA, Cushman & Wakefield, and NASA JPL**. Kev at a venture-backed startup, where he scaled agentic infrastructure to **40,000+ concurrent users** and later built AI video-generation technology that generated **$XX,XXX in its first month**.\n\n# **Our Asks**\n\nIf you are, or know, any of the following, we'd love to hear from you:\n\n**Home service business owners and operators**: especially HVAC, plumbing, electrical, roofing, and other residential service companies with growing technician teams dealing with high call volume, missed or after-hours calls, slow speed-to-lead, overloaded office staff, open estimates, manual follow-up, or plans to hire another CSR.\n\nIf you're evaluating an **AI receptionist, virtual receptionist, or after-hours answering service** for a home service business, we'd especially like to talk.\n\nYou can reach us at [kyle@centralcoms.com](mailto:kyle@centralcoms.com)\n\n![uploaded image](/media/?type=post&id=114503&key=user_uploads/1562583/fd756d59-f73e-44d5-a9b8-c90b721c0a5a)\n\n![uploaded image](/media/?type=post&id=114503&key=user_uploads/1562583/eecee51b-deef-486e-809c-9e783b963a56)\n\n", "url": "https://www.ycombinator.com/launches/Tmp-centralcoms-ai-answering-service-for-the-trades", "votes": 4, "created_at": "2026-09-10T01:51:06.075Z" }, { "id": 102115, "title": "CentralComs: AI Agents for Residential Property Managers", "tagline": "Your 24/7 AI Property Manager, Maintenance Coordinator and Leasing Agents", "body": "# \n\n---\n\nHey everyone 👋\n\nWe’re Kyle and Kevin; co-founders of CentralComs. We’re children of landlords and are building a solution to a problem we saw all throughout our childhoods.\n\n**TL;DR**\n\nWe run property management workflows such as **leasing, back office, and maintenance coordination workflows from start to finish,** so PM teams run smoother and earn more with the same team size.\n\n\n\n### **The Problem**\n\nProperty management operations are relentless, high-stakes, hands-on work built on relationships with owners, tenants, and vendors that take years to earn and seconds to lose.\n\nIt's overwhelmingly manual: **roughly 90% of the work is still manual** and extremely labor-intensive with **89% of property management companies outsourcing work** to teams overseas.\n\nAbout half of leasing inquiries come in at night and on weekends, when no one's answering. **Conversion drops 7x after the first hour**.\n\nUnresolved work orders are a top reason tenants don't renew, and **every lost renewal costs thousands** once you count turn and vacancy.\n\nThe work is rules-based and repetitive, but it demands constant attention, and missing any single step breaks the chain. That's why these roles scale so badly with headcount— you're paying for someone to be awake at the right moment to do menial tasks.\n\n---\n\n## **Our Solution**\n\n**Maintenance Coordination Agent** Takes a maintenance request from submission to resolution:\n\n* **Intake across any channel** — captures requests from email, SMS, and tenant portals, normalizing them into a single queue\n* **Intelligent triage** — applies a proprietary relative and objective scoring algorithm to prioritize and triage issues in real time as conditions change\n* **Smart dispatch** — routes to the right vendor based on trade, availability, and cost, sends the dispatch, and tracks confirmation\n* **Persistent follow-up** — chases vendors, tenants, and owners intelligently until the job is on track and on schedule\n* **Repair verification** — confirms work was actually completed via tenant sign-off, photo evidence, and vendor confirmation before closing the loop\n* **Invoice processing** — validates invoices against the scope of work and approved estimates, flags discrepancies, and routes for payment approval\n* **Owner & tenant updates** — keeps all parties informed at each milestone without manual outreach\n\n**Leasing Agent** Takes a prospect from first inquiry to complete application:\n\n* **Cross channel intake** — captures leads from listing syndication, email, SMS, web forms, and phone, normalizing them into a single queue\n* **Intelligent qualification** — applies a proprietary relative and objective scoring algorithm to qualify and prioritize prospects in real time as new information comes in\n* **Smart routing** — matches each lead to the right unit, schedules the tour, sends the application, and tracks completion\n* **Document analysis** — reviews submitted IDs, pay stubs, and bank statements, flagging income, completeness, and inconsistencies against your criteria\n* **Verification & screening** — runs identity verification and background/credit screening, then compiles a clean, decision-ready file\n* **Persistent follow-up** — chases prospects intelligently until they're marked qualified\n\n**What makes us different than traditional PMS systems?**\n\n* We handle can handle edge cases proactively, asking for more information, reading documents, and determining the best course of action\n* We don’t automate reply drafts, we send out messages, dispatch calls, retrieve missing information, and push stalled work-orders or application processes to completion.\n\n---\n\n## **Our Ask**\n\n**If you answer \"yes\" to any of these, we'd love your help:**\n\n* Do you know any residential property management operators whose teams are stretched thin, managing multiple systems just to keep up with maintenance and leasing?\n* Do you know any property management companies looking to scale operations without increased labor cost?\n\n**Contact**\n\nReach us at [**founders@centralcoms.com**](mailto:founders@centralcoms.com) or schedule a demo

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.

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" } ] } ]
