Hacker Houses

SF's iconic hacker house where AI founders and researchers live and build together. Hosts regular AI meetups, demo days, and fireside chats — a central hub of the Cerebral Valley ecosystem.

Operated by the global Entrepreneurs' Organization. Exclusive to proven founders doing $1M+ in annual revenue. Features structured peer learning and mentoring programs with exceptionally high network density and trust.

SF's longest-running hacker house since 2013. Uniquely self-governed by residents with no owner. Famous for its legendary density — 'meet 3 founders and a VC before you brush your teeth.'

A residency program backed by Sam Altman. Intensely ambitious builders gather for short-burst focused projects. Follows a 'Subtraction philosophy' — eliminating variables to focus purely on what matters.

Operated by the Cerebral Valley community. Hosts regular AI hackathons, demo days, and founder dinners. One of the most active event hubs in the SF AI ecosystem.

A community space where ex-big-tech engineers and researchers explore their next chapter. You can join without a clear idea — the exploration itself is supported. Alumni include Aravind Srinivas (Perplexity CEO).

A private membership club at SF's Ferry Building. More co-working + commune than hacker house — a high-density networking space mixing founders, VCs, and creators. Waterfront views and premium F&B.

A Seoul-based hacker house by Team Attention. Bringing the density of SF hacker houses to Korea. A space where AI-native builders live, build, and grow together.
