CollX

CollX is a Philadelphia-area startup whose mobile app lets collectors snap a photo of a sports or trading card and instantly identify it and see its current market value. Built around AI visual search trained on a database of more than 17 million cards, CollX has grown from a quick valuation tool into a full collection-management platform and peer-to-peer marketplace where over 3 million users scan, organize, price, buy, sell, and trade cards. The company monetizes through Pro and Gold subscriptions, marketplace commissions, and referral revenue from hobby partners like PSA, Whatnot, and Fanatics.
