Washington State product studio
Comfortable software, seriously built.
We design and build modern digital products — software, mobile apps, online services and AI — with the craft of a big team and the focus of a small one.

Who we are
A lean studio, end to end
Puffy Slippers Tech LLC is an independent studio. We take ideas from a rough sketch to a shipped, maintained product — without the overhead, the lock-in, or the cut corners.
