What it is CardAuthentico is a trust-first, AI-native marketplace for trading sports cards. We rebuilt the collector-to-collector experience from scratch around three things eBay and Facebook groups can't offer: verified identity, escrowed money, and intelligent search.
Why we exist The sports-card market is worth billions, but the buying experience hasn't changed in twenty years. Collectors get burned by counterfeit cards, vanishing sellers, payment fraud, and disputes with no clear arbiter. We've all paid for a card that never arrived — or received one that wasn't what was pictured. CardAuthentico was founded in 2024 by collectors who got tired of it.
How it works
- KYC-verified onboarding. Every account — buyer or seller — passes through our identity-verification partner before they can transact. Sellers go through additional screening. If you can't prove you're a real person, you can't list a card.
- AI-powered natural-language search. Describe what you want the way you'd describe it to a friend — "Mahomes rookie autos under $2k" or "1990s basketball inserts in graded condition" — and our AI assistant returns matches across the catalog. No filter pyramids, no boolean queries.
- Stripe escrow checkout. Buyer funds sit in escrow until the card arrives and the 48-hour inspection window passes. Sellers can't disappear with your money. Buyers can't claim non-delivery on a delivered card.
- Tracked shipping + 48-hour buyer protection. Every order ships with tracking. Buyers have 48 hours after delivery to flag a problem before funds release.
- 30-day dispute resolution. If something goes wrong, our team arbitrates — fast and impartially. No black-box reversals, no waiting weeks for a response.
Who it's for
- Buyers who want to know the seller is a real, verified person before sending money.
- Sellers who want their listings to stand out against a sea of unverified accounts.
- Collectors who'd rather describe a card in plain English than navigate 40 filter dropdowns.
- Newcomers who don't know the jargon yet and need search that understands intent.
