Sam Yagan knows he’s been lucky. He tells us that one of the luckiest moments of his life was meeting his college roommates. Together, they built a study guide website called SparkNotes. Then, they built an online dating empire. They started the site OKCupid while Yagan was getting his MBA at Stanford. Yagan is now the CEO of ShopRunner, but he’s best known for his 7-year tenure as the head of the Match Group, which includes OkCupid, Match.com, and Tinder. He says it was his Syrian immigrant parents who inspired his drive to be an entrepreneur.
