Independent software studio

We build software people keep using.

FoundrPrompt designs, builds and operates consumer applications for iOS and the web. We work on a short list of products at a time and run every one of them ourselves.

Hanzi AI

汉字 · 爱

A Chinese learning app built around spaced repetition and the iPhone Lock Screen, so vocabulary reaches you through the day instead of waiting in a queue. Thousands of words with native audio, adaptive review, and daily slang.

The studio

Small team, whole lifecycle.

We handle product design, engineering, content pipelines, analytics and day-to-day operation in house. Nothing is shipped and abandoned — every product we launch is one we keep running and improving.

Our focus is consumer software where everyday usefulness matters more than novelty: tools built to be opened again tomorrow, and the day after that.
