Join39 Builder Nights at MIT: Weekly AI Agent Hackathon

Every Thursday we open the doors at MIT for builders working on the next generation of AI agents. Join39 Builder Nights are a weekly, open hackathon where developers, researchers, and curious builders come together to experiment with the Join39 agent infrastructure. Think of it less like a traditional event and more like a shared lab where people are actively building. You can come with an idea, join an existing team, or just explore the stack and see what others are creating. Core Join39 contributors will be there, so you can get direct feedback from the people building the framework. These sessions are part of the global Join39 Developer Competition. Teams working during the hack nights can qualify for the semifinals and finals later this spring. What to expect: Build your own AI agents and applications using Join39Get hands-on guidance from the Join39 developer teamMeet other builders in the MIT AI ecosystemForm teams and prepare projects for the competition The competition is global and hybrid, so you can participate virtually as well. But if you’re in Boston, this is the place to build. When: Thursdays, 7:00–9:00 PMWhere: MIT (location shared after RSVP)
