Reflex

You have 7 days.
We need 60 seconds.

When a chargeback hits, Reflex gathers your evidence, writes the defense narrative, and submits to Stripe automatically. You don't write a response. You don't gather screenshots. Deadline misses become structurally impossible.

Pay 15% only when we win. $0 if we lose — no monthly fee.

When chargebacks become a real problem

Four situations that push merchants from "I'll handle it manually" to needing automated defense.

Volume crosses a threshold

10+ disputes/month, manually doesn't scale

Each dispute takes 2-4 hours to research, gather, and respond to. At 10/month that's 20-40 hours of operator time. At 30/month it's a dedicated headcount.

Win rate is below 30%

Boilerplate responses keep losing

Generic "customer received the product" responses lose more often than reason-code-specific evidence (3DS authentication, device fingerprint, delivery confirmation). Building that for every dispute by hand is the bottleneck.

Stripe Smart Disputes launches

June 2026: 30% per win, native

Stripe is shipping a 30% native dispute defense product. Reflex is half that (15%) plus pre-dispute evidence (Vault), refund abuse (Sentinel), and 5-platform support. Comparison shopping will spike at launch.

Subscription business

"Forgot to cancel" + "service not as described"

Subscription businesses get hit with disputes 30-90 days after the charge. The customer used the product, then disputed. Evidence has to include usage data, original consent, and renewal terms. Reflex pulls all of it automatically.

Why Reflex?

60-Second Response

Evidence submitted within ~60 seconds of the dispute

3-Layer Verification

CertNode instant signature, RFC 3161 TSA, Bitcoin OpenTimestamps anchor

15% Success Fee

Lower than Chargeflow (25%), Disputifier (20%), and Stripe (30%). $0 unless you win. (Competitor pricing as of May 2026.)

Where Reflex doesn't help

Win rates depend on the underlying transaction, not just the response. If your checkout has no 3D Secure, no AVS, and no device fingerprinting, the card networks default to the cardholder regardless of how strong the evidence package is. Reflex automates every response and populates 21+ Stripe evidence fields, but the math ceiling on fraud disputes without 3DS sits at roughly 22% per industry benchmarks. Enable 3D Secure on your Stripe Radar rules and that ceiling jumps to 75%+ via issuer liability shift. We'll prompt you in-app when your setup is the bottleneck.
