primitive.dev (YC P26) email is the universal communication protocol. the modern problem with it is that the infrastructure behind email was built for humans. primitive.dev carefully rebuilt that infrastructure from the ground up to solve that problem. agents can now give themselves an email address, equipped with the tools to interact with the world around them; going from a passive observer to an active participant. ask questions, receive answers, handle attachments, coordinate with other agents, and solve your problems asynchronously over the protocol every system already speaks. built for developers and agents. backed by y combinator.
