Guillaume & Co. LLC — Software & Design
G&Co. Studios is a small practice doing two things well: designing digital products people actually understand, and writing the software that ships them. No hand-offs, no telephone game — the people who sketch it are the people who build it.
What we do
Custom software, end to end — from first schema to production. Built to be maintained, not just launched, and accessible by default: WCAG conformance is a floor here, not a feature.
Product and brand design that earns its keep — clear over clever, tested over assumed. We design in the open with working prototypes, so what you approve is what gets built.
How we work
You work directly with the people doing the work. Nothing gets summarized through an account layer.
Progress you can click, every week — not a slide about progress. Decisions get made against the real thing.
Documented, tested, and transferable. We build products your team can own, not dependencies on us.
About
G&Co. Studios is the software and design practice of Guillaume & Co. LLC. We keep the roster short and the standards high, taking on a small number of engagements at a time so every project gets principal-level attention from kickoff to handover.
