I always like looking these folks up on youtube to see if they have any interviews, this guy did talk for Chicago Techweek, and his story starts remarkably similar to another tech dude who was recently charged with fraud... goes something like this:

Also this one is amusing given the context "you win if you're not afraid to break rules and do things the way they're best done in the new reality"
