David Rogier

Though MasterClass remains based in the tech hub of San Francisco, Rogier was born and raised in L.A.’s wealthy Brentwood neighborhood, the grandson of Holocaust survivors. By his own account, he struggled in school as a child but ultimately graduated from Stanford GSB, one of the world’s top business schools. MasterClass was founded in 2015 by Rogier and Aaron Rasmussen and has since raised nearly $500 million in venture capital. Today, the company offers 100+ courses from dozens of celeb instructors, thousands of lessons — and a whopping $2.75 billion valuation.
