AgentMail, a San Francisco–based startup developing infrastructure for autonomous artificial intelligence agents, has raised $6 million in seed funding to expand its platform designed to give AI systems their own email capabilities. The round was led by General Catalyst, with participation from Y Combinator, Phosphor Capital, and angel investors including Paul Graham, Dharmesh Shah, Paul Copplestone, and Karim Atiyeh.
Founded by CEO Haakam Aujla, AgentMail provides an API that allows AI agents to create and manage dedicated inboxes capable of handling conversations, threading, labeling, searching, and replying to messages. The platform aims to enable AI systems to interact with existing internet services using email as an identity and communication layer.
Since launching in Y Combinator’s Summer 2025 batch, the company reports attracting tens of thousands of users, hundreds of thousands of agent accounts, and more than 500 enterprise customers, reflecting growing interest in autonomous AI workflows across digital services.
