Like many college students, Brandon Pitts, now 32, spent much of his time in undergrad playing Madden and NBA 2K. Unlike most of his peers, though, he managed to turn his avocation into a burgeoning e-sports empire. Since 2011, the entrepreneur has hosted local tournaments, where everyday players bet money on themselves in hopes of winning a grand prize. Last month, his company introduced software called 1/0S that allows anyone to host a tournament to benefit their own local club or organization through his company's Tournament Partner Program.
