Ship AI in production with senior operators.

We're a small, senior team shipping AI systems for real customers on real infrastructure. If that sounds like your speed, we'd like to hear from you.

How we work.

No standups that last longer than the work. No decks that replace decisions. Small teams, clear scope, and receipts for every claim we make.

Ship the real thing

We don't do proofs of concept that never ship. Every engagement has production as the goal — and evals to prove it.

Evidence over opinion

We measure what we ship on real data. If the numbers don't move, neither do we.

Founder-led craft

Every engagement is senior. No hand-offs to junior teams, no armies of PMs in the middle.

Distributed + async

Kansas City and Tokyo today. Remote-first, async-first, written-first — the work is the work.

Roles we hire for.

We partner with senior operators on a contractor basis for most engagements, and hire full-time when the load is there. These are the profiles we look for.
