Born in Germany, Thiel moved to the US with his parents when he was an infant. In 1971, his family moved to South African-occupied Namibia, before moving back to the US in 1977. After graduating from Stanford University, Thiel worked as a clerk, a securities lawyer, a speechwriter, and a derivatives trader at Credit Suisse. He founded Thiel Capital Management in 1996 and co-founded PayPal with Max Levchin and Luke Nosek in 1998. He was PayPal's chief executive officer until its sale to eBay in 2002 for $1.5 billion.
Thiel then founded Clarium Capital, a global macro hedge fund based in San Francisco. He launched Palantir in 2003, a big data analysis company, and has been its chairman since then. In August 2004, Thiel became Facebook's first outside investor by acquiring a 10.2% stake in the company for $500,000.
