Nominee for Best Marketplace

CollX is a mobile app that combines AI-powered card scanning with real-time pricing and a built-in marketplace. The platform has processed more than 1 billion card scans, from 4 million collectors, reflecting its widespread adoption among collectors who use it to identify, value, and manage their cards.


In 2025, CollX continued to enhance its marketplace tools, allowing users to list cards for sale directly after scanning, make and accept offers, and complete transactions entirely within the app. Its ecosystem supports both raw and graded cards across major sports and trading card games.


By pairing instant recognition technology with an accessible buying and selling experience, CollX has become a leading mobile hub for collectors - bridging the gap between discovery, valuation, and trade.
