Independent software, built narrow and built to be checked.

Three products, in three fields with nothing to do with each other.

Replication infrastructure for PostgreSQL fleets. Computer-vision coaching for young athletes. An offline audio player for iPhone.

What they share is a way of working. Each one does a single job all the way to the end rather than many jobs partway. Each says plainly what it does with your data, including the awkward parts. And where a claim can be checked instead of trusted — a replica that has genuinely converged, an app that genuinely holds no account — it is built so you can check it.
