CardAuthentico

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

1. 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.
2. 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.
3. 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.
