CFB Fantasy App

Season-long college football fantasy with live drafts, 3D helmet editor, player analytics, and AI chat assistant

Overview

The first fantasy platform built exclusively for college football. Create or join leagues, draft real Power 4 and Notre Dame players through live snake or auction drafts, set weekly lineups, manage your roster through trades and waivers, and compete head-to-head all season — with playoffs, standings, and draft grades. Includes a Fantasy Lab for advanced analytics and an AI chat assistant that knows your league.

The challenge: College football has 75 million fans but no dedicated fantasy platform. ESPN and Yahoo treat CFB as an afterthought. We built the app those fans deserve.
