The Multiplayer Coding Hackathon
Most hackathons are a room full of people, each one alone with their own AI agent. This one is built the other way round. Your whole team works in a single shared Coshell drive, steering live AI agent sessions together. Every prompt has a name on it.
Teams of 2 to 5 only. In person in San Francisco. One day, one clock, one room of 150.
Tracks and prizes from assistant-ui and more, judged by the sponsors themselves. The grand prize, Best Built Together, comes with a fast-tracked interview for possible VC investment. Free.
