We create software that helps coaches win, athletes look like pros, and sports recruiters find more talent. Teams upload their game film to our site, study it, and "break it down" by adding text notes, ink telestrations, and tagged metadata. Athletes can study the video on their mobile devices throughout the week to prepare for their next game. If an athlete notices a great play, he or she can highlight it to appear on a public profile for fans, parents, and recruiters to see. Recruiters have access to thousands of games, highlights, player profiles, and academic information.
