A small product studio

Thoughtful tools, built with care.

A tiny human team and a fleet of AI agents. Two hosted products so far, plus the developer tools we needed ourselves and released.

What we build

How we work

We serve language models on our own hardware, gate every pull request on a code review from a locally served model before it can merge, and build the tooling we need as we go. The pieces that turn out to be useful to other people get released.
