Founding Story
Mailgent is an open-source, Cloudflare-powered email infrastructure project for AI agents, positioned as an AgentMail alternative. It was created by Ran Aroussi, the developer behind widely used open-source tools like yfinance. The project lets developers give AI agents a real inbox (name@mailgent.dev), an encrypted credential vault, 2FA/TOTP generation, a calendar, a did:web verifiable identity with an Ed25519 keypair, and a funded USDC wallet on the Base blockchain — with no SaaS lock-in or servers to manage.
