Mox

Mox is San Francisco's largest AI safety coworking and community space, occupying four floors and approximately 40,000 square feet at 1680 Mission Street. It was founded in February 2025 by Austin Chen (CEO of Manifund) and Rachel Shu, who serves as Director. The founders observed that most AI safety community hubs were located in Berkeley while the important AI lab work was concentrated in San Francisco, and created Mox to close that gap. In its first year of operation, Mox grew to 183 active members with 50 to 80 people present on typical coworking days. The space offers 15 private offices, numerous hot desks, conference rooms, a gym, and a nap room. Mox operates a Guest Program with 19 partner organizations, giving their team members free drop-in access; public partners include MIRI, FAR.AI, Redwood Research, BlueDot Impact, Palisade, GovAI, EPOCH, AI Impacts, Timaeus, Elicit, Evitable, and MATS. Over its first year, Mox hosted 377 events including major conferences such as the Sentient Futures Summit (350+ attendees), fellowships (FLF Fellowship on AI for Human Reasoning with 30 fellows, PIBBSS Fellowship 2025 with 17 fellows, Seldon Lab Accelerator Batches 1 and 2 with 10 startups total, and the Frame Fellowship for video creators), and recurring community programs including EA SF meetups, Astral Codex Ten SF discussions, and machine learning reading groups. Mox operates as a project of Manifund. Its Year 1 annualized costs were approximately $1.2M, funded through a mix of grants (~$800K from Craig Falls/EAIF and Manifund) and earned revenue (~$600K from memberships, private offices, and fellowship fees). As of early 2026, Mox generates approximately $100K per month in revenue against roughly $130K in monthly expenses, resulting in a net monthly burn of approximately $30K. The organization is fundraising for 2026 with a primary goal of $450K and a stretch goal of $1.2M, supported by a 1:1 donation match up to $100K from an anonymous donor.
