HF0 (previously Hacking the Future Observatory) runs a 12-week live-in residency ('hacker monastery') in San Francisco for repeat technical founders. Participants receive $1,000,000 via an uncapped SAFE for 5% of the company (or an alternative $500K + 3% equity). The program is highly intensive, culture-focused, and invite-only. Only experienced startup builders are typically admitted.
Repeat technical founders with prior startup experience; applicants must be ready for an all-in living program in SF and have a strong prototype or traction.
