Build in a Day. Showcase on a Global Stage.

This hackathon isn’t simply a one-day sprint; it’s an accelerator for your idea. Finalists will demo their projects LIVE at MongoDB.local New York City on September 30th.

The next chapter of agentic infrastructure is memory, persistence, and self-evolving systems. Join us for a hackathon with the MongoDB team focused on solving the hardest problem in agentic AI: building harnesses that can adapt, remember, and operate reliably over the long haul.

We're looking for impactful projects built with MongoDB Atlas, Vector Search, and Agentic Memory tooling. Whether you're building agents that rewrite their own guardrails, systems that hold context across weeks-long tasks, or entirely new approaches to persistent agent memory, this is your opportunity to build the infrastructure the next generation of agents will run on.

🥇 Prizes

$15,000 in cash prizes will be awarded across the three final teams, and more prizes will be announced!

📝 Judges

Top judges from MongoDB, our partners, and the NYC ecosystem will be joining us. Stay tuned for the full lineup.
