Simple pricing.
Pay only for results.
One proof engine, five storefronts. The flagship — chargeback defense — has no monthly fee: you pay 15% only when we win.
Chargeback defense
We gather the evidence, build the defense package, and submit it. You pay only when we win the dispute back.
Reflex
Done-for-you dispute defense
No monthly fee. Cryptographic evidence captured before the dispute, packaged to the FRE 902(13)/(14) self-authenticating standard, and submitted automatically. Half the rate of Stripe Smart Disputes (30%) and Chargeflow (25%+).
- ✓ Evidence package + legal framework per dispute
- ✓ Stripe live; Shopify, PayPal, Square, WooCommerce in beta
- ✓ No win, no fee — ever
The same pay-on-win model covers AI-agent purchases and returns & warranty disputes.
Capture & monitor
Seal the facts at checkout. Defend them later. These feed dispute defense and catch abuse before it hits.
Evidence Vault
Captures up to six evidence points — 3DS, AVS, CVC, device fingerprint, IP, authentication result — sealed with a 2-layer cryptographic timestamp before any dispute exists.

The same engine, as an API: sign critical events — an AI output, an agent action, a document — and verify them anywhere, without trusting the original system. Sign up, get a key, pay by usage.
