Without PayPal, there may not have been Palantir. Or YouTube. Or SpaceX, LinkedIn, and Yelp.
The payments company - launched as Confinity in 1998 by Peter Thiel, Max Levchin, and Luke Nosek - grew to become a Silicon Valley giant. It was acquired by eBay in 2002 for $1.5 billion in a deal that altered Silicon Valley history and helped spawn the careers of some of tech's most famous names.
The PayPal Mafia, as its early employees came to be known, have gone on to become venture capitalists, tech founders, and even a US ambassador.
Here are the tech companies that may not have gotten their start without the success of PayPal.

When it came time for YouTube to sell, the team intentionally chose a price of $1.65 billion — 10% more than what eBay sold for.
