Sounds impressive, but I'd like to know if all of the company's schools are private and therefore selective. If so, the students' success doesn't reflect on the company. Those students would have been successful anyway. The best that can be said is that the company doesn't get in the way.
Anybody who wants me to believe he can make educational miracles happen will have to make them happen in public schools, where he won't be allowed to teach only the best and the brightest.
