Who are we?

We step in when the problem stops being purely technical: architecture, code, organization and business constraints tangle together, and adding more tools stops helping.

Our first job is to make the system legible: separate what needs to evolve independently, find what’s common beneath the symptoms, and identify the few principles that explain the essential. We then build, with your teams, the simplest structure that holds.
