A two-day in-person hackathon in New York run by MongoDB, aimed at the hardest problem in agentic AI: harnesses that adapt, remember and stay reliable over long tasks. Teams of up to four build with MongoDB Atlas, Vector Search and Agentic Memory tooling, working on persistent agent memory, context held across weeks-long tasks, or agents that rewrite their own guardrails. Three finalist teams share $15,000 in cash prizes and demo live at MongoDB.local New York City on September 30th. Attendance requires an approved application, and finalists must record an on-site demo and present at the .local event.
