Most hackathons end at the demo. This one is built to continue.

The GTransformer AI Buildathon 2026 is a 3-day hybrid buildathon (in person in Milpitas, Bay Area + online) for builders who want to point AI at problems that matter — and leave with a working prototype, not just a pitch deck.

North star: AI for human flourishing. Every project should be able to answer one question: who does this measurably help, and how?

Themes

• Wellbeing — Help people understand, protect and improve their mental and emotional wellbeing before problems become crises: emotional awareness, burnout, access to care, early warning.
• Connection — Move people from isolation or thin digital interaction toward meaningful, safe human connection: belonging, matching, community, and the reason to actually meet.
• Learning & Opportunity — Expand access to education, skills and economic mobility: AI tutors, learning-gap detection, teacher copilots, career pathways, job matching, financial literacy.
• Responsible AI — a requirement across every project, not a separate track. Every team addresses safety, privacy, bias, accessibility, transparency, and potential unintended harm.

Schedule (Pacific Time)

• Fri, Nov 13, 6–8 PM — Kickoff & team formation
• Sat, Nov 14, 9 AM–5 PM — Build day with mentor office hours
• Sun, Nov 15, 9 AM–5 PM — Demos, expert feedback & next steps

Who should join: students, builders, engineers, designers, PMs, researchers, founders and domain experts. No team? No problem — teams form at kickoff.
