Most enterprise AI fails not because the model is wrong, but because the choreography between human and machine is left to accident. We treat every workflow as a conversation with a shape — where authority sits, where doubt is surfaced, where a human is asked to lean in and where they are wisely left alone.
Our practice draws from cognitive ergonomics, control theory, and twenty combined years of building interfaces that survive contact with real operators. We ship systems, not slides.
Two weeks of listening. Sitting alongside operators, mapping the actual grain of the work.
2 weeksA written architecture and interaction brief. Diagrams sparse, decisions numbered.
3–4 weeksHands on the keyboard alongside your engineers. Shipping into production behind a feature flag.
12–20 weeksEvaluations, incident review, and gentle refactoring as the model landscape moves.
