About
A studio that runs on leverage, not headcount.
Trevillyan Labs is an independent software studio. We build and run our own products, ship software for clients, and advise founders on product and go-to-market execution.
Who's behind it
The studio is run by Bill Trevillyan. He builds and operates Trevillyan Labs' own products alongside select client engagements.
Day to day, the studio is operated with Ren, an AI assistant — Trevillyan Labs runs lean on agentic AI rather than headcount. It's how we move fast and deliver at senior quality without an agency's overhead, and it's the lived proof behind the AI work we advise on.

Meet Bill
The founder behind the studio.
Bill Trevillyan is a product leader and 3x startup founder. He's built and shipped products across early- and mid-stage startups, holds two issued US patents, and now runs Trevillyan Labs — building and operating its own products alongside select client work.
Away from the keyboard, he lives off of good coffee, gets out for backpacking and tennis, and will happily travel (or cook) for cuisines from anywhere in the world. He's based in Mountain View, CA — the heart of Silicon Valley.
Let's build something worth shipping.
