- AgentMail: email inboxes for AI agents. My own agents run their email on it, and their new AgentID gives an agent its own sign-in instead of borrowing mine. (I use it, and I’m an investor.)
- Daytona: sandboxes where my agents run code and browsers without touching my machine. (I use it, and I’m an investor.)
- T3 Code: the harness my long-running agents live in; it’s how the ones you read about here actually work day to day.
- Claude Code and Codex: the two coding agents I use most, Anthropic’s and OpenAI’s.
- Grok Bot: xAI’s agent, which I use like a mini employee for repeatable workflows. (Grok Bot has been a paid sponsor of this newsletter.)
- Railway: where my apps get deployed. I give my agents API access and the hosting just gets handled.
