London MongoDB User Group

Build in a day. Shape the future of AI Agents. 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 London on May 7th.

AI agents are breaking free from passive chat interfaces and starting to learn, adapt, and grow alongside us as autonomous partners, driven by breakthroughs like OpenClaw’s viral action-taking runtime and Hermes’ self-improving, persistent skills.

Now, we need to architect the next stage: creating the integrations, memory systems, and self-evolution mechanisms that allow agents to build intelligence that embeds seamlessly into our everyday lives.

Build with MongoDB and London’s best hackers to define how agents evolve from chat-bound tools into indispensable, ever-improving intelligence.

Prizes include £15,000 in cash and partner credits, awarded across the top three teams.

Notes:

• This event is fully in-person in London. Space is limited. Maximum team size is four. All attendees must submit an application and be approved to attend.
• In order to be eligible to win, finalists must be available on May 7th to attend MongoDB.local London and present their project.
