We measure savings against your own baseline. We show the math. If we don't find at least 3× our annual fee in verifiable savings in your first 90 days, we'll refund the unused portion.
What we promise
Each item is verifiable. Click the verification link where applicable.
3× annual fee or refund
Within 90 days of pilot kick-off, if the verified savings are < 3× the prorated CARTIE annual fee, we refund the unused portion. No fight, no clawback gymnastics.
Open-math savings ledger
Every dollar of attributed savings carries the input, the assumption, and the engine that produced it — downloadable as a signed JSON ledger. You can re-derive every line yourself.
Algorithm correctness, in public
Our core engines (Shapley K8s, Cost-Bisect, Causal Bot) are validated against mathematical ground truth in a public test manifest. Verifiable in one click.
