Build w/ MongoDB & the best hackers in AI at MongoDB's .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, & 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, & business systems to maintain & 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 & the right data at the right time.

Build with MongoDB & 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 money

1 year of Cursor Ultra (~$2,400 value)

Backstage passes for the DJ set (TBA!) at the .local Build Fest After Party

Partner credits, swag, & more!
