Hack for Social Impact 2026

Inside the event

🚀Make an impact on real world problems in a single weekend!🚀 HSI is back for our third year in a row! Join Hack for Social Impact once again to tackle real-world challenges. We are teaming up with non-profit partners to present you with important and well-scoped challenges, in partnership with UN Convention to Combat Desertification and 4 local nonprofits. This event is supported by our sponsors: Gemini, Bild.ai, and Wefunder. Developers will receive credits during the hackathon to work on your projects from our sponsors and technology partners. $5000 cash prizes in total for the winners of projects This year, we've teamed up with incredible partners to tackle pressing issues in mental health, climate, justice reform, and art & design: 🌎 Climate: Work with the UN to build an interactive game to enable the community to participate in land planning! Block by Block is a Minecraft-based tool for communities to design their own streets, and has run in 55 countries since 2012. However, it is unsuited to UNCCD's work in real-world land planning: Minecraft has endless resources, arbitrary terrain, and no consequence to player actions. Build a game from real satellite and GIS data showing the impact of land use, to engage the community. 🩷 Mental Health: Boundless Freedom Project can reach people inside with mindfulness and mental health practice through in-person sessions and the Edovo tablets. On release that support falls away, during the 30 days that hit hardest. Build something that keeps familiar practice at hand, holds as little personal information as possible, and assumes no smartphone and no dependable internet. ⚖️ Justice Reform: California's corrections department spends under one percent of its budget on rehabilitation. Transformative Programming Works advocates for them across 120 organizations, but so far can only track process data such as who enrolled and how long a class ran. Join disjoint records such as parole and recidivism data into a framework TPW, and nonprofits generally, can use to track impact. 🎨 Art & Design: BRIDGEGOOD's Oakland studio teaches designers to build with their own communities in mind, through conversations about identity, money and conflict that only work in a small room with a facilitator in it. That room seats a few dozen people a year. Find a way the practice can travel to designers who will never sit in it, without thinning into a slide deck. 🏆 Past winners went to present at UN Climate Conference and build startups that get accepted to YC and raise seed funding!🎯Will your weekend hack be next year's success story? ✨Register your interest and follow us on our LinkedIn for more Partner & Prize announcements ✨ For more information on the event and a recap of last year, visit our website! ✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨ 🤝 Who should sign up?
