About Company

CatchBack Cards is a mobile app and website platform for maximizing the thrill of collecting Pokemon and Sports cards. We allow collectors to create custom mystery packs with personalized chases and customized odds with cryptographically trusted tooling. Users can rip open digital packs and get physical cards shipped to them, receive buyback offers on cards pulled from their mystery packs sent straight to Venmo and PayPal, and buy/sell cards in our $1 marketplace.

Joseph Zhang

Founder

Hi there! I quit my job to sell Pokemon cards. prev SWE at Nexus, consultant at McKinsey, SWE at AWS, Gates Scholar and ISEF finalist I'm passionate about the intersection of innovative technology, sustainability, and resource allocation/equity. In my free time, I enjoy playing squash, creating pop remixes/mashups, and reading everything from Fantasy to biographies, as well as shamelessly looking up the answers to the New York Times crossword puzzles.
