AI-powered electrical estimating that hunts its own mistakes.
Most contractors throw a number at it and hope it sticks. We don't guess.
The goal
“Make mistakes mechanically impossible.”
Calibrated against the real job
variance — estimate vs. the real job

We grade and publish our accuracy.
Nobody else in this business will.
We don't just estimate.
We grade ourselves against the real job.
Every job we price, we go back and check the estimate against what the work actually cost — then we publish the result. The wins, and the ones that ran wide.
