Sept 11–12, 2026
Building for SF runs on the organizations that know this city block by block — neighborhood groups, civic orgs, and the people already doing the work teams will build on.
Partners shape what teams work on and make sure what gets built has somewhere to land after the weekend.
Community and civic organizations that name a real problem on their block, so teams build against something concrete instead of a hypothetical.
Firms and groups that lend designers, engineers, planners, and policy staff to circulate during build day and help teams get unstuck.
Space, food, hardware, data access, or printing — the practical support that lets a two-day buildathon actually happen.
Confirmed partners are listed here as they come on board ahead of the weekend.
More organizations are coming on board ahead of the weekend, and they'll be listed here as they're confirmed.
If your organization works on housing, small business, public space, or neighborhood capacity in San Francisco, we'd like to hear from you — whether you bring a problem, mentors, or a room.
