In collaboration with Edelman and Treehouse Fabrication & Scenic, Cognition produced a five-day experiential activation for eBay at the National Sports Card Convention in Chicago. The large-scale footprint featured an eBay Live stage, a custom-built pop-a-shot game, interactive touchscreen learning stations, and a gamified scavenger hunt app that sent guests across the convention floor to scan hidden codes and uncover high-value grails or climb the leaderboard. As the official sponsor of the event, eBay’s presence was amplified with a prominent conference center wrap and immersive on-site engagement.
