HFO

HF0 is a 12-week residency in San Francisco where ten teams of engineer-founders relocate into a house to focus exclusively on building their next venture , run by Dave Fontenot and Evan Stites-Clayton . This launch is a short documentary that pulls back the curtain on a recent batch, intercutting candid demo-day numbers with footage of teams sleeping in warehouses, flying experimental airships, and confronting their weekly KPIs in front of peers. It is timed to the opening of interviews for the next cohort. The film makes the case that the program now works for companies well past the idea stage. Featured residents include Float (logistics), Ultrapi (described in the video as working on superintelligence), a rigid-airship startup, an AI agent project from a founder introduced as Richie, and a European healthcare company that the founder claims went from zero to a $250M annualized run rate during the residency. One participant references coming in at $90M after signing a $15M contract, and the launch tweet notes that five of the ten teams crossed $10M annualized by demo day, which is the central point HF0 is making with this release: four of ten teams break $3M in revenue by demo day, four of ten break $2M, and the top team breaks $10M . The throughline is the "one thing" philosophy, the idea that each founder picks a single weekly KPI and is held accountable to it in front of the room. For repeat founders weighing whether to step back into a structured environment, the documentary functions as both a recruiting artifact and a public update on what the program now selects for, which is operators looking to compress a year of progress into a quarter rather than first-time builders searching for product-market fit.
