Bring Your Playbook To Life

The World’s First Holographic Training Platform for Football

PRE-GAME PREP with HoloReps is the next level of immersive, interactive training and game day preparation for professional and college football teams. Players don’t just study and memorize the playbook–they experience it anytime, anywhere.

Whether it is the Digital Walkthrough projection system designed for team practices or the mixed reality HoloReps system that merges holographic players with the practice field, players from any position can step through their playbook or prep for upcoming opponents, gaining mental reps as well as the muscle memory of in-person training.


Football teams never have enough time to get all the necessary reps of hard-to-recreate gameday scenarios.

PRE-GAME PREP is the solution.

Coaches design plays in seconds using their own playbook for formations, defensive fronts, and coverages – and customize them for any opponent. Players can then experience the plays from any angle and in rapid succession – all in a controlled, non-contact environment. No injuries. No wasted training time.

PRE-GAME PREP creates gameday results. Players achieve mastery of the playbook well before kickoff–so when something unexpected happens, they can make quick decisions, and dominate the competition.


  • Experience the game from any player’s perspective
  • Players can practice anywhere, anytime with built-in coaches’ notes
  • Create an unlimited number of fully customizable plays
  • Project life-sized players for walkthroughs
  • Interactive installs and immersive quizzes to accelerate learning
  • Quarterbacks can get full-speed reps with no risk of injury
  • Next Gen Stats (NGS) integration
