HF0 is a highly selective twelve-week residency for repeat and technical founders, run by Dave Fontenot. It has taken batches since 2021. HF0 covers living expenses during the residency, allowing founders to focus entirely on building their startups. Its last published terms were $1M uncapped for 5% equity; HF0 removed the figure from its site in late 2025. The program was inspired by Fontenot's earlier work founding MHacks (the world's largest hackathon) and HackMatch. HF0's demo days are notoriously oversubscribed.
