about this event
Hack for Social Impact (HSI), in partnership with leading Bay Area nonprofits and supported by sponsors including Google and Bild AI, is a two-day hackathon bringing together talented engineers and data scientists to develop technical solutions for pressing social challenges.
Held on October 24–25, 2026 at Wefunder, San Francisco, the event mobilizes Silicon Valley's technical community to build deployable data and software solutions for mission-oriented organizations. This year's hackathon features five partner organizations: Transformative Programming Works, Boundless Freedom Project, the East Bay Permaculture Guild, BRIDGEGOOD, and the United Nations Convention to Combat Desertification (UNCCD). Together, they work across critical areas such as criminal justice reform, reentry, community regeneration, design education, and land restoration.
In addition to cash prizes and project grants, participants have the opportunity to continue collaborating with partner organizations to bring their solutions to impact. Previous HSI winners have presented at the UN Climate Conference and launched startups accepted into Y Combinator.
