Peter Andreas Thiel (born 11 October 1967) is a German-American entrepreneur, venture capitalist, and conservative political activist. He is a co-founder of PayPal, Palantir Technologies, and Founders Fund, and was the first outside investor in Facebook. As of August 2026, Forbes estimated Thiel's net worth at US$32 billion.
Born in Frankfurt am Main, Germany, Thiel moved to the United States as an infant. His family lived in Cleveland, Ohio, and later in South Africa and South West Africa (modern-day Namibia) before settling in Foster City, California, in 1977. He attended Stanford University, where he studied philosophy and co-founded The Stanford Review, a conservative and libertarian newspaper. After graduating from Stanford Law School in 1992, he worked as a law clerk, securities lawyer, speechwriter, and derivatives trader before founding Thiel Capital Management in 1996.
Early Life and Education
Peter Andreas Thiel was born on 11 October 1967 in Frankfurt am Main, Hesse, to Klaus Friedrich Thiel and Susanne Thiel. The family emigrated to the United States when Peter was one year old, settling in Cleveland, Ohio, where his father worked as a chemical engineer. Thiel's biographer Max Chafkin noted that leaving booming Frankfurt for Cleveland, which represented the American countercurrent, had an impact on the family. Klaus worked for various mining companies, leading to an itinerant upbringing for Thiel and his younger brother, Patrick Michael Thiel. Thiel and his mother later became U.S. citizens, while his father did not.
Before settling in Foster City, California, in 1977, the Thiel family lived in South Africa and South West Africa during the apartheid era. Peter changed elementary schools seven times. He attended a German-language school in Swakopmund for two years, which required uniforms and used corporal punishment, such as striking students' hands with a ruler. Thiel later said this experience instilled a distaste for uniformity and regimentation, influencing his support for individualism and libertarianism. The German community in Swakopmund was known at the time for its continued glorification of Nazism. Thiel was described as a smart but lonely and withdrawn boy, with whom others would not mingle because they knew he would not stay long.
Thiel played Dungeons & Dragons and was an avid reader of science fiction, with Isaac Asimov and Robert A. Heinlein among his favorite authors. He is a fan of J. R. R. Tolkien's works, stating as an adult that he had read The Lord of the Rings more than 10 times.
Thiel excelled in mathematics, scoring first in a California-wide mathematics competition while attending Bowditch Middle School in Foster City. At San Mateo High School, he read Ayn Rand and, influenced by his parents, admired Nixon and Reagan. He was valedictorian of his graduating class in 1985. While in high school, he reportedly charged $500 each to take the SAT for underclassmen, knowing this would cost him his spot at Stanford if discovered.
Thiel studied philosophy at Stanford University. The replacement of a "Western Culture" program with a "Culture, Ideas and Values" course that addressed diversity and multiculturalism prompted him to co-found The Stanford Review, a conservative and libertarian newspaper, in 1987. The paper received funding from Irving Kristol. Thiel was its first editor-in-chief until he graduated in 1989. He has maintained his relationship with the paper, consulting with staff and donating to it. According to Marc Andreessen, Thiel's time at the Review marked the beginning of a career-long strategy: using provocative verbal cues to attract capable individuals to his projects. The Review has spawned a large network of industry leaders, with around 300 people having worked for or received investment from Thiel or Joe Lonsdale, another prominent editor-in-chief and Thiel's mentee.
After graduation, Thiel attended Stanford Law School, graduating in 1992 with a Juris Doctor degree. While at Stanford, he met René Girard, whose mimetic theory influenced him.
Early Career
After graduating from Stanford Law School, Thiel served as a law clerk to Judge James Larry Edmondson of the U.S. Court of Appeals for the Eleventh Circuit from 1992 to 1993. He then worked as a securities lawyer for Sullivan & Cromwell in New York, leaving in under a year. In 1993, he took a job as a derivatives trader in currency options at Credit Suisse, while also working as a speechwriter for former U.S. Secretary of Education William Bennett. Thiel returned to California in 1996.
Upon returning to the Bay Area, Thiel capitalized on the dot-com boom. With financial support from friends and family, he raised $1 million toward the establishment of Thiel Capital Management and embarked on his venture capital career. Early on, he invested $100,000 in his friend Luke Nosek's unsuccessful web-based calendar project. Soon thereafter, Nosek's friend Max Levchin described his cryptography-related company idea, which became their first venture called Fieldlink (later renamed Confinity) in 1998.
PayPal and Founders Fund
Thiel provided the initial $100,000 for Fieldlink in 1998. In February 1999, Confinity launched PayPal, a digital payment service. Thiel served as CEO until the company's sale to eBay in 2002 for $1.5 billion. The sale made Thiel a multimillionaire and established his reputation as a successful entrepreneur.
In 2005, Thiel launched Founders Fund with PayPal partners Ken Howery and Luke Nosek. The venture capital firm has invested in numerous technology companies, including OpenAI and SpaceX. Thiel also co-founded Valar Ventures in 2010, founded Thiel Capital in 2011, and co-founded Mithril Capital in 2012, serving as investment committee chair.
Palantir Technologies
In 2003, Thiel launched Palantir Technologies, a big data analysis company, and has been its chairman since then. Palantir specializes in software that helps organizations analyze large datasets, often for intelligence and defense purposes. The company has grown significantly, with contracts from U.S. government agencies and commercial clients. As of 2026, Palantir remains a major player in the data analytics industry.
Facebook Investment and Other Ventures
In August 2004, Thiel became Facebook's first outside investor by acquiring a 10.2% stake in the company for $500,000. This investment proved highly lucrative, as Facebook (now Meta Platforms) grew into one of the world's largest social media companies. Thiel later sold most of his stake but remained on the board until 2022.
Thiel has also been involved in various other ventures. He was granted New Zealand citizenship in 2011, which became controversial when made public in 2017. Through the Thiel Foundation, he governs the grant-making bodies Breakout Labs and Thiel Fellowship. The Thiel Fellowship, launched in 2011, awards $100,000 to young people to drop out of college and pursue their own ventures.
Political Activism and Views
Thiel has been variously portrayed as a conservative libertarian and democracy-skeptic authoritarian. He has made substantial donations to American right-wing figures and causes, including support for Donald Trump's presidential campaigns. Commentators and scholars frequently examine his views, particularly his political and ideological positions. He has been described as "a political theologian operating at the heart of the Silicon Valley" and the "intellectual architect of Silicon Valley's contemporary ethos".
Thiel's political philosophy is influenced by his reading of René Girard and his libertarian beliefs. He has expressed skepticism about democracy and has advocated for a more hierarchical society. His views on AI and technology are often intertwined with his political ideology, as he sees technological innovation as a means to escape political stagnation.
AI Investments and Influence
Thiel has been an active investor in artificial intelligence companies. Through Founders Fund and personal investments, he has backed firms such as OpenAI, DeepMind (before its acquisition by Google), and various AI startups. His interest in AI aligns with his broader vision of technological progress as a driver of human freedom and prosperity.
Thiel has also funded research and development in AI through the Thiel Foundation, supporting projects that explore the societal implications of advanced technologies. His influence extends to policy discussions, where he has advocated for a more proactive approach to AI development and regulation.
Legacy and Impact
Peter Thiel's impact on technology and venture capital is profound. He co-founded PayPal, which spawned a cohort of successful entrepreneurs known as the "PayPal Mafia," including Elon Musk, Reid Hoffman, and others. His early investment in Facebook demonstrated his ability to identify transformative companies. Palantir has become a key player in government and corporate data analysis.
Thiel's political activism and controversial views have made him a polarizing figure. Nevertheless, his contributions to the tech industry and his role in shaping Silicon Valley's culture are widely recognized. As of 2026, he continues to be an influential voice in technology and politics.
