The Harness Engineering & Model Wrangling Hackathon

MongoDB's next chapter of agentic infrastructure is memory, persistence, and self-evolving systems.

Join us for a hackathon with the MongoDB, as well as our supporting partners — AWS, OpenAI, Fireworks, Vercel, Openrouter, ElevenLabs — 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.

Top judges from across MongoDB's ecosystem will be joining us, and prizes will be announced soon.

Note: This event is fully in-person in NYC. Space is limited. Maximum team size is four. All attendees must submit an application and be approved to attend.

If selected as a finalist we require one person from your team to record a demo on-site September 26th which will then be displayed at .local NYC. To be eligible to win, finalists must also be available on September 30th to attend MongoDB.local NYC and present their project.
