Overview The Buff Nation Fan Challenge is a season-long digital game for University of Colorado football fans, run by Thropic with CU Athletics, and its presenting sponsor rides from the weekly email to the Folsom Field video board on home game days. Thropic builds its games on predictions, brackets and trivia with a live leaderboard, and the CU challenge carries a branded trivia question for its sponsor. Colorado's 2026 schedule put six home games at Folsom Field, among them Texas Tech for homecoming, Utah for family weekend and a Friday night against Houston. On site At the stadium the sponsor appears on the video board and in PA reads at every home game, with 30 to 60 in-game placements across a season. Off the field, CU Athletics sends the weekly challenge emails and Thropic serves co-branded posts from CU's own verified handles. The Buffs' live buffalo mascot is Ralphie VII, introduced in September 2025 after Ralphie VI retired. Track record Thropic describes itself as gamification software for fundraising. In 2026 its site listed Colorado among its partners alongside Ole Miss, Syracuse, Texas A and M, St. Jude, NBCUniversal and the College Basketball Crown, and put the average raise across a university season at $184,000. Brand presence The presenting sponsor gets school-delivered media, paid media served by Thropic, in-game placements, prizing, reporting, and athlete-produced NIL content it keeps. The game collects opted-in fan profiles, and the sponsor owns that first-party data at the end of the season.
