Sanju Bansal

COO of MicroStrategy

“Sanju is very utilitarian. Everything he owns has to have some sort of use—like he won’t wear a watch because his BlackBerry tells the time just fine. He’s got his own look with the black, square-rimmed glasses. His friends call it ‘SB style.’ It’d be a mistake to think he’s a geek, though, because he’s really the opposite. He has an understated confidence that’s always right on the surface.”
