Don't take our word for it. Take the arithmetic.
Three claims, each one checkable. This page grows as real jobs land — what's here is only ever what we can show.
Deterministic
Same inputs, same price, forever. Not “usually” — structurally. Price the same job twice and the answer doesn't move, because nothing in the engine guesses.
Explainable
Every dollar traceable to a physical fact of the job. A price is a breakdown, not a number: labor, distance, access — each line computed from something you can point at.
Calibrating
Outcomes move rates through propose-and-confirm — never silently. When a job runs long, the engine proposes which rate was off; the firm approves it or doesn't. One thing moves without a click, and we say so: for a firm that hasn't entered its own running cost, the fuel part of that cost follows the government's weekly diesel price — read automatically, checked against two publications, and the firm is told when it moves. Every quote keeps the figures it was priced with.
Quoted versus actual — with consent, with the real numbers.
The first quoted-versus-actual pairs from our founding firms will be published here, with their consent, as they land. We'd rather show you a short honest page than a long illustrative one.
Every change to the engine, dated, in public.
We have no customer logos to show you yet, and we are not going to borrow anyone else's. What we can show you is the whole history of the thing that sets your prices — 101 recorded changes, each one dated. Every change is tested against 186 jobs with known prices before it ships. A change that moves any of them is listed and signed off first; every other price must come back exactly as it was — not close to it, the same to the cent.
When a change moves a price, that is a decision somebody made and recorded, not something that happened to you overnight.
