Proof
The pattern, on real work.
Two things stand behind the promise: the person who builds it, and the first system running in a real business.
The person
Kevin McNamee
Founder, Mainline Systems
Kevin runs an engineering organization of more than 150 at FanDuel across pricing, trading, and risk, where an automation mistake costs real money in real time. He has led that organization's adoption of agentic AI across the full development lifecycle and has watched automation succeed and fail at scale. It fails when it skips the record and the review gate. It succeeds when a person owns the number.
Before that he built and scaled engineering teams from early stage to that size across several industries, including as VP of Engineering at Bowery Farming. He builds with his own production AI tooling every day. Mainline's systems are the same pattern, built for businesses that price, schedule, and promise custom work.
The first build
A senior estimator's judgment, as rules plus a model, behind a review gate.
The first Mainline system is an estimating system for a custom fabrication shop that quotes from renders and site photos. A render goes in. A structured list of components comes out. The estimator confirms the parts and dimensions. Rules classify materials and methods, a model handles the remainder, a take-off prices every line from the shop's own cost memory with a reason on each one, and the estimator approves the estimate before it is frozen.
It runs on the shop's real work. Its first live run misclassified one material. The fix became a rule and a test that the next client inherits. That loop, a mistake becoming infrastructure, is the whole method.
The case study, with the client's numbers, lands when their next phase does. Until then this page carries the pattern and not the figures.
The proof you can see now is on your own data
Every Blueprint ends with three to five of your real past inputs run through a thin slice of your top-ranked workflow, next to what your business actually did. You do not have to take our word for it, or the pilot's.
