Sept 11–12, 2026 · San Francisco
A civic buildathon for people who want San Francisco to work better — designers, engineers, policy nerds, and anyone with a fix worth prototyping. Teams form around real civic problems and ship a working project in a weekend.
Ever walked past an empty lot or vacant storefront and thought, what if this became something incredible? Or wondered how you’d redesign your neighborhood for abundance? This is your chance to build real things: policy proposals, prototypes, and advocacy tools to design the SF we actually want to live in.
Meet your team, hear from people working on SF's toughest civic problems, and get oriented for the weekend.
A full day to design, build, and iterate, with mentors circulating to help teams get unstuck.
Every team demos what they built. Projects get published here afterward for the city to see.
Kickoff night features practitioners already doing this work across the city.
Full details, including mentor office hours and demo format, are on the schedule page.
RSVP takes about thirty seconds — no application, no essay, no cost. Tell us what you're good at and we'll match you onto a team by skill and district before the doors open. Show up Friday, ship something by Saturday.
