They power power billions of business interactions yearly _(think: lead qualification, customer onboarding, client intake, feedback forms, surveys, event RSVPs, registration forms, compliance, healthcare…the list goes on),_ but most have:\n\n* **Low conversion:** too many users provide half-answers or drop off before completing.\n* **Time drain:** teams waste hours building complex logic, chasing non-responders, hand-holding, and cleaning messy data.\n* **Poor user experience:** even when forms do work, they frustrate users and hurt your brand.\n\nTeams have been forced to tolerate these pain points as there's been no scalable alternative for collecting structured information from people - until now.\n\n---\n\nhttps://www.youtube.com/watch?v=MrchVB7RHmg\n\n\\\n**Solution**\\\nWith RowFlow, we abstract away from the static form structure altogether. It works like this:\n\n1. Say what data you need ([or try our Google Form converter](https://rowflow.ai/)).\n2. RowFlow runs guided AI conversations over text, Slack, email, or embedded chat with automated follow-ups.\n3. You get clean, structured data delivered into your systems.\n\nOur goal is for RowFlow to become the new default way for how organizations collect needed user data in an AI-first world.\n\n---\n\n**Ask:**\n\n1. Do you have a form with low response rate? If so, we’d love to help - [**you can book a call with us here**](https://calendly.com/rowflow/discovery-call)!\n2. If you have to fill out a form in the wild that makes you go 🤬, send a screenshot to [**jack@rowflow.ai**](mailto:jack@rowflow.ai) and we’ll take it from there.\n\n\\\n**About Us:**\n\nJack and Alec met as freshmen at UPenn and we always knew we’d build something together. 12 years later, we are!

Try it at .\n\n> For a limited time, every team chat account also gets free daily access to state of the art open-weights intelligence, GLM 5.2 at high speed, through our partnership with [Wafer.ai](http://Wafer.ai).\n\n\n\n## The problem\n\nThe bottleneck in software has moved. Execution is basically free now: AI agents can write, test, and ship code 24/7. _The new constraint is human decisions and verification_. Whoever surfaces the right decision to the right person at the right moment unlocks 10x throughput. Whoever doesn't watches their agent fleet stall.\n\nIf you've ever tried to keep three coding agents productive at once, you know the feeling. You jump between PR tabs, miss approvals buried in Slack, and find one agent has sat idle for 20 minutes waiting on a one-line decision. It's a fascinating moment to be building software: vastly easier and vastly harder at the same time.\n\n![uploaded image](/media/?type=post&id=103435&key=user_uploads/19683/9019e12e-5088-4b41-9321-28a417dade5a)\n\n## How Linzumi works\n\nConnect your machine, kick off work in chat, and review what every agent is doing from your laptop, your phone, or the coffee line. Works with Codex today, Claude Code coming soon. Your teammates see it all too: agent work is no longer buried in invisible terminals.\n\n\n\nBut the real unlock is underneath. As your team works, Linzumi keeps every decision close to the work itself: what to build, why it changed, who approved it, and what the agents should do next. The decision inbox surfaces only the calls that need a human, so instead of reconstructing context from terminals, PRs, chats, and memory, your team has one shared place to steer the whole fleet.\n\n_Continuous Context Compilation_\n\n\n\n## Backstory\n\nI'm a 3x YC founder. Before Linzumi I was at OpenAI on post-training and alignment research, where I worked on systems for making models follow written specs and produce more reliable reasoning. Working with coding agents on my own projects showed me the same kind of coordination problem at the team level: the agents could execute, but the bottleneck was deciding what should happen next and checking whether the result matched intent.\n\nThe mission now is to make everyone the CEO of their own 1,000-agent company: able to direct more work, make better decisions, and become the best version of themselves as a builder.\n\nWhen you combine that shared context with calibrated decisions, even the smallest form factor can do surprising amounts of work, like shipping a customer feature from your phone on the way to the meeting.\n\n_Hands-free work_\n\n\n\n## What we're asking for\n\nIf you run AI coding agents (or want to), try Linzumi at . It's free to get started and we'd love your feedback.\n\nWe're especially looking for:\n\n• Engineering teams running multiple coding agents who want to scale to dozens (honestly, thousands by end of year)\n\n• Founders who feel like the bottleneck in their own dev cycle\n\n• Anyone curious about better human-agent coordination for company-scale work\n\nDM me on X (@sgrove) or email [sean@linzumi.com](mailto:sean@linzumi.com).
