AgentMail gives AI agents their own email inboxes, the way Gmail does for humans. YC S25, $6M seed led by General Catalyst, with Paul Graham among the angels. More than 500 companies build on it. We did the brand and website from 0 to 1: a secret agent in a fedora for the mark, monospace type and ASCII skylines, and agent.email, a page written for the agents themselves. Not agents for email. Email for agents.
