The Persistent Context Sprint Hackathon | Live at MongoDB .Local Build Fest

Build in Less than a Day. Showcase on a Global Stage. The next generation of AI apps are built on systems that can remember, retrieve context, and take action over real application data. In this sprint hackathon, build AI applications powered by agent memory, where models work with databases, APIs, documents, code, and business systems to maintain and improve context over time. Whether you are creating autonomous developer tools, adaptive copilots, or entirely new AI experiences, explore what becomes possible when intelligence is grounded in persistent memory and the right data at the right time. Build with MongoDB and the best hackers in AI on-site at MongoDB’s .local Build Fest in San Francisco. Participants will join us on-site at Build Fest for a dedicated ~5-hour hacking block. A panel of first-round judges will select finalists, who'll then demo their projects on stage in front of the full conference reception before a winner is crowned. Winners will receive a truly unique prize package, including: $15,000 in total prize money1 year of Cursor Ultra (~$2,400 value)Backstage passes for the DJ set (TBA!) at the .local Build Fest After PartyPartner credits, swag, and more!
