Multiplayer Hackathon by Party (SF)

Multiplayer Building is here. Google Docs made documents collaborative.Figma made design collaborative.Now, Party is making building collaborative. At this event, you'll get a glimpse of the future of building with agents: together in the open. We pack the room with founders, engineers, product leaders, hackers, designers, etc and we'll all work with agent teams to build something amazing. Agent teams do the heavy lifting on objectives (not prompts) while everyone in the room steers. You'll leave with something you were part of making (hosted publicly), some new friends, and a totally refreshed outlook on building great products. This event is absolutely free. You’ll join the rest of the group on our community Party space where the tokens are free and you can see/steer everything that’s cooking.
