Alumni Q&A
- How did your company get started? (i.e., How did the founders meet? How did you come up with the idea? How did you decide to be a founder?)
- The three founders met while building Garry's List and were frustrated by having to re-enter API keys and re-explain their work each time they switched between AI tools, none of which supported team use. They built an agent setup with shared memory, skills, and external integrations for themselves and friends, then turned it into gbrain.io, a cloud, multiplayer version that configures itself in one click.
Summarized from the founders' answers on their Y Combinator profile.
