With AI, anyone can build anything. The hard part isn't building; it's figuring out what's worth building. And that almost always happens when two co-founders are in the room together, riffing on ideas and reacting to each other in real time. But today's AI coding tools are single-player by design. They've turned the most important moment of a startup into a solo activity with a demo at the end.

We're building a multiplayer workspace where co-founders can shape ideas as fast as they can code them. Explore, build, and decide together in real time, so you get to conviction faster and ship the things actually worth building.

We're currently in preview release with a small group of co-founders. If you'd like to try it, join the waitlist and we'll let you in as we expand.
