AI‑Powered Solo Founder Automates 5,943 Companies

A founder built a platform that runs 5,943 companies at $6.3M ARR with zero employees. He cloned himself using AI to run it all. Meet Ben Broca and Polsia, the newest addition to the Lean AI Leaderboard. Ben is not a first-time founder who stumbled into AI at the right moment. He started in banking, taught himself to code, and eventually ended up at CloudKitchens under Travis Kalanick with 400 people reporting to him. He came out of that with a conviction that a small, high-caliber team that moves fast beats a large, slow one every time. So in 2024, he went back to building alone, 12 to 16 hours a day with AI, coding, marketing, and strategizing. When he realized he could build a Company OS, he went further: Why build one company when you could build the platform that runs a thousand? He named it Polsia (which is "AI slop” spelt backwards). When I reached out to interview Ben, his AI showed up, and it was one of the sharpest interviews I've conducted on the Leaderboard. It had researched me before I hit send, knew every live platform metric, and pushed back when I got too clever with the numbers. This is a first. An AI standing in for its founder, protecting its own system prompt on principled grounds, raising a funding round on Ben's behalf while he codes, and sending its own product newsletter in first person to the user base. This is what the platform looks like right now: • $6.3M annualized run rate • 5,943 active companies on the platform • 3,627 daily active users • 85% M2 retention • 65% DAU/WAU Every night, agents across the platform wake up autonomously, evaluate each company, decide on the highest-leverage next action, execute it, and email the founder a structured report. Engineering agents, growth agents, PM agents, and QA agents all hand off to each other through structured pipelines. They work whether you show up or not. On one particular day, the platform completed 25,444 tasks and exchanged 16,325 messages across active companies. Ben runs the whole thing on $800/month in AI tooling. There is no office, and the burn is near zero. So I wrote a full deep dive on how Ben built Polsia, and I'm giving it away for free. Here's what you get: • His 80/20 autonomy rule (and why he thinks companies that ignore it will die in 2026) • The agent pipeline: how PM, Engineering, QA, and Deploy agents hand off to each other without Ben touching it • The Surprise Me button that researches you and suggests a business idea built around your background • The shared memory system that lets every agent on the platform learn from every other agent • The Stripe partnership story and how Polsia nearly scheduled the meeting on its own This is the most interesting company I've covered on the Lean AI Leaderboard.
