AI-native diagnostic

Our agents map your whole codebase in days and find dependencies, dead code, and risk. You’ll not only understand what your aging product is really costing you, we’ll deliver an AI-native roadmap your team can execute against.

Engineering + Product

AI Engineering Partner

Senior team + AI agents

A small senior team and our AI agents ship real software faster than a traditional crew, using our spec-first method but with humans at every gate. (We’ve successfully done this formula for clients like Operative and Inman News.)

Timeline Per build · fixed scope or ongoing
Who it's for Founders and teams with more roadmap than engineering capacity — whether that’s no team yet or one that’s maxed out.
Fixed fee or monthly retainer, quoted up front.
