The AI Engineering Partner for mid-market companies.
We help engineering teams ship AI to production, on a method proven over a decade of building and shipping software. Two ways in: a fixed-scope AI Diagnostic that produces a written roadmap, then a full AI Implementation that builds it.
What we do
AI is not a single feature. We work across the three places it creates leverage inside a software company.
AI software development
A team of AI agents managed by human engineers, shipping production software in days, not months.
AI features in your product
AI built into the product itself, the capabilities your customers will expect within twelve months.
Company OS
Agents running the operational, repeatable work inside the company, with humans owning the checkpoints.
Sellito Studio
Sellito Studio is our own AI-native company: a productized website service for veterinarians in Mexico, delivered in seven days. It runs on the same agentic operating model we build for clients. We sell the model because we operate on it.
See it live
A real business running on the agentic model, in production with paying customers.
