Give AI agents real email inboxes to receive and respond to messages independently.

Give your AI agent a @yourcompany address. Shipped the domain part this week and it's free We've been building email for AI agents. The idea is that an agent gets a real inbox, not a webhook, so it can receive things and answer in thread like anyone else on your team. The piece that was missing until this week was the address itself. Every agent lived on our domain, which is fine for a demo and wrong for anything real, because a domain where anyone can grab a free address in ten seconds loo

New JD for software engineers: Loop Engineering Boris Cherny, who built Claude Code, said: "I don't prompt Claude anymore. I have loops running that prompt Claude and figuring out what to do. My job is to write loops." Straight out of latest newsletter, another good summary of how engineers' roles are shifting... The ultimate automation of engineers' job and any operations job using AI loops is a good answer to mangers, investors and shareholders. Especially in the async organization like Babylon Labs, where I have colleagues in 10+ time zones.

Thank you to everyone who joined our "map your TAM from the terminal" session with last week. We built live in the terminal using Claude Code and the MCP. I wrote up the whole thing afterwards. The seven stages, why each one exists, what to do with the list once you have it, and the outreach half we covered at the end. The recording is linked inside. The skill is public too, so you can run it on your closed-won book. You bring your own accounts; the engine does the expansion, scoring, and contact-finding. Comment "TAM" and I'll send you both skill and guide.
