Jeremy Stoppelman founded Yelp, the online reviewing site, in 2004, after graduating from UIUC’s computer engineering program in 1999. He spent some time at PayPal while attending Harvard Business School, but dropped out to start Yelp.
Stoppelman was the VP of engineering at PayPal and is often mentioned as one of the “PayPal Mafia” members. At PayPal, he also met Max Levchin, who was one of the early investors of Yelp.
Yelp is now publicly traded and had revenue of roughly $232 million in 2013.
