Growing up, David's grandmother instilled an important lesson: that the only thing someone can't take away from you is your education. So when a mentor of David's offered to back him as an entrepreneur, he decided to bring the joy back to education and build a school that everyone would want to attend. In 2015, he launched MasterClass, which now provides classes from 100+ of the world’s best practitioners (from Serena Williams to Martin Scorsese). MasterClass has grown into one of the largest online learning platforms in the world and was most recently valued at nearly $3 billion dollars. David shares why a childhood stutter impacted his entrepreneurial ambitions, why starting with the best teachers was critical to his business strategy, and the importance of getting two opinions (and no more) when making a hard decision.
