The private community for Y Combinator founders.
Bookface is Y Combinator’s private community for its founders, which YC describes as a combination of Facebook, Quora and LinkedIn, with tools for fundraising, hiring and scheduling. Bookface is for YC founders only, so connecting it takes a YC account.
Connected to a workspace, GBrain can bring what the YC community has shared into the team’s questions, like “what have founders said about hiring a first salesperson?”
GBrain gives Bookface a command line too. From a terminal, a
script or Claude Code,
gbrainio tool help bookface
lists its commands once it is connected.
You sign in on Bookface's own page. No key to copy. Then add it to a workspace, and anyone on the team can ask about it in plain words.
