Who we are:

MasterClass is transforming online education by enabling anyone in the world to learn from the very best.  We are deconstructing what makes an actor able to cry on demand, how an athlete defies gravity, and what it takes to write a bestseller.  Our online learning content is available to students anywhere anytime, which supports our mission to ignite the greatness in others.

We are a quickly growing VC-funded startup based in San Francisco, with additional offices in Los Angeles.  We have created online classes taught by famous masters— Gordon Ramsay, Serena Williams, Neil deGrasse Tyson, Sara Blakely, David Sedaris, Bobbi Brown, Timbaland, Anna Wintour and many more to come.
