About CollX & Card Dealer Pro

CollX is changing the face of card collecting, bringing computer vision, machine learning, and other technology to the Hobby. We began by solving a very simple and age-old problem: helping collectors figure out what their cards are worth. The CollX app, launched in early 2022, enables anyone to snap a photo of a trading card, instantly ID it, and get the current market value. From there you can scan your collection, follow your friends, and buy, sell or trade with others. The app has quickly grown to more than 2.5 million users, with 1 million cards added daily.

Card Dealer Pro is another piece of software we built for professional dealers that allows them to rapidly document and price their cards and sell them across multiple marketplaces. This software can enable a store to not only sell online, but to sell in massive numbers. Our customers have reported that CDP has helped them to double their available inventory and revenue!
