What is Housecat?

Housecat is the inbox that helps you get real work done.

We build a bespoke email app that connects to your tools, helping you with the real work that happens before and after sending an email.

Connect external tools like your CRM, Slack, Granola or Claude and turn your inbox into a powerful operating system to run your whole business. Update your CRM, start or edit docs, trigger agent research or query your finance system. All without leaving your inbox!

Under the hood, Housecat gives you a dedicated AI agent, private server, and connections hub that you can customize however you want.

Email hasn’t changed in 30 years, and if anything it’s getting worse. There’s too much noise and spam. It’s an unstructured mess where broken promises and forgotten tasks gather dust, and you always feel behind the curve. Worst of all, email acts as your to-do list, trapping tasks in a tool that can’t take action.

That’s why we’re building the future of email. You deserve better!
