The "PayPal Mafia" is a group of former PayPal employees and founders who have since founded and developed additional technology companies[1] such as Tesla, Inc., LinkedIn, Palantir Technologies, SpaceX, Affirm, Slide, Kiva, YouTube, Yelp, and Yammer.[2] Most of the members attended Stanford University or University of Illinois at Urbana–Champaign at some point in their studies.
