A partner at venture capital firm Founders Fund, Thiel was Facebook's first outside investor. In 1998, Thiel co-founded PayPal and served as its chairman and chief executive officer until it was acquired by eBay in 2002. Thiel has also worked at investment bank Credit Suisse and law firm Sullivan & Cromwell.
