Peter Thiel

Peter Andreas Thiel ( ; born 11 October 1967) is a German-American entrepreneur, venture capitalist, and conservative political activist. A co-founder of PayPal, Palantir Technologies, and Founders Fund, he was also the first outside investor in Facebook. As of August 2026, Forbes estimated Thiel's net worth at US$32 billion.

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. In 2005, he launched Founders Fund with PayPal partners Ken Howery and Luke Nosek. He co-founded Valar Ventures in 2010, founded Thiel Capital in 2011, co-founded Mithril Capital in 2012, was investment committee chair in 2012, and was a part-time partner at Y Combinator from 2015 to 2017. 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.

Thiel has been variously portrayed as a conservative libertarian and democracy-skeptic authoritarian, and he has made substantial donations to American right-wing figures and causes. 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".

Peter Andreas Thiel was born in Frankfurt am Main, Hesse on 11 October 1967, to Klaus Friedrich Thiel and Susanne Thiel. The family migrated to the United States when Peter was one year old and lived in Cleveland, Ohio, where his father worked as a chemical engineer. Thiel's biographer Max Chafkin comments that leaving the booming Frankfurt, which was West Germany's financial capital, for Cleveland which was representative of the American countercurrent, had an impact on the family. Klaus worked for various mining companies, which created an itinerant upbringing for Thiel and his younger brother, Patrick Michael Thiel. Thiel and his mother later naturalized as U.S. citizens, whereas his father did not.

Before settling in Foster City, California, in 1977, the Thiel family lived in South Africa and South West Africa (modern-day Namibia) in the time of apartheid. Peter changed elementary schools seven times. He attended a German-language school in Swakopmund for two years that required students to wear uniforms and employed corporal punishment, such as striking students' hands with a ruler. He said this experience instilled a distaste for uniformity and regimentation later reflected in his support for individualism and libertarianism. The German community in Swakopmund was known at the time for its continued glorification of Nazism. Thiel was noted as a smart, but lonely, withdrawn boy, with whom others would not mingle because they knew he would not stay long in the town.

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 and scored 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. When at 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 at Stanford with a "Culture, Ideas and Values" course that addressed diversity and multiculturalism prompted Thiel to co-found The Stanford Review, a conservative and libertarian newspaper, in 1987. The paper received funding from Irving Kristol. Thiel was The Stanford Review's first editor-in-chief until he graduated in 1989. Thiel has maintained his relationship with the paper, consulting with staff and donating to the newspaper. According to Marc Andreessen, Thiel's time at the Review marked the beginning of a career-long strategy: using provocative verbal cues – later delivered through talks, books and mottos – as a way to attract capable individuals to his projects, preferring this method over actively seeking out talent. The Review has spawned a large network of industry leaders, among whom Andrew Granato and the Fortune respectively identify around 300 people who have worked for or received investment from Peter Thiel or Joe Lonsdale, another prominent editor-in-chief and Thiel's mentee. A number of Review alumni have also become public officials, beginning with Jay Bhattacharya and Paula M. Stannard who were editors during Thiel's time as editor-in-chief.

After graduating from Stanford Law School, Thiel was a law clerk to Judge James Larry Edmondson of the U.S. Court of Appeals for the Eleventh Circuit from 1992 to 1993. Thiel then worked as a securities lawyer for Sullivan & Cromwell in New York. He left the law firm in under a year. He then took a job as a derivatives trader in currency options at Credit Suisse in 1993 while also working as a speechwriter for former United States 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 experienced a setback after investing $100,000 in his friend Luke Nosek's unsuccessful web-based calendar project. Soon thereafter, Nosek's friend Max Levchin described to Thiel his cryptography-related company idea, which became their first venture called Fieldlink (later renamed Confinity) in 1998.

Thiel provided the initial $100,000 for Fieldlink in 1998. In February 1999, they raised $500,000 largely from friends and family ($35,000 was from Thiel's parents). By middle 1999, they raised $4.5 million, with Nokia Ventures contributing $3 million.

With Confinity, Thiel realized they could develop software to bridge a gap in making online payments. Although the use of credit cards and expanding automated teller machine networks provided consumers with more payment options, not all merchants had the necessary hardware to accept credit cards. Thus, consumers had to pay with exact cash or check. Thiel wanted to create a type of digital wallet for consumer convenience and security by encrypting data on digital devices, and in 1999 Confinity launched PayPal.

PayPal promised to open up new possibilities for handling money. Thiel viewed PayPal's mission as liberating people from the erosion of the value of their currencies due to inflation.

Thiel is described by different authors and media sources in different ways. He identifies as a libertarian. He has been called an Ayn Rand libertarian, plutocratic reactionary, militarist techno-libertarian, and libertarian authoritarian. His attitude towards democracy has been described as "skeptical", partly antidemocratic, or post-democratic. French economist Yann Algan links Peter Thiel and Elon Musk to the concept of "liquid democracy" and the rise of libertarian AI governance, which Algan defines as "a radically decentralized, algorithm-driven democracy", which "prioritizes efficiency and individual freedom over democratic safeguards".

Thiel's biographer Max Chafkin notes that his thinking is a mix of libertarianism and authoritarianism, but describes what Thiel truly believes and wants as a mystery.

Thiel describes himself as a political atheist. He opines that trying to radically alter the current U.S. government is unrealistic. He also suggests that Curtis Yarvin methods will lead to Xi's China or Putin's Russia. He does not deny the value of statesmanship though, but opines that "people should spend less time trying to change the system than simply creating things outside it".

Journalist Murad Ahmed from Financial Times calls Thiel "philosopher king at the very top of Silicon Valley" (with France 24 using a similar description). German philosopher Peter Sloterdijk also remarks: "Peter Thiel can be seen as more of a philosopher king. He acts very coolly and strategically – a dazzling figure, far outside our left-liberal perception patterns", while Ross Douthat from New York Times describes him as "most influential right-wing intellectual of the last 20 years". Commenting on Douthat's description, Luke Munn of the University of Queensland notes that, "Thiel's influence on politics is at once financial, technical and ideological [...] his potent cocktail of networks, money, strategy and support exerts a rightward force on the political landscape."

In 2025, the author Ijoma Mangold wrote an article for Die Zeit, describing Thiel's theories as obscure and incoherent at first glance, argues he often displays an accurate "intuition", while noting that both the man and his ideas "simultaneously fascinates, repels, and outrages." Subsequently the author René Martens, writing for Mitteldeutscher Rundfunk, criticized Mangold and Die Zeit for masking their admiration with pseudo-criticism and called Thiel a disciple of Nazi-supporter Carl Schmitt.

Thiel carries out most of his philanthropic activities through the Thiel Foundation.

He has advocated for billionaires to withdraw from The Giving Pledge, a commitment to donate at least 50% of one's wealth, promoting instead a form of philanthropy focused on businesses and innovation.

In 2006, Thiel provided $100,000 of matching funds to back the Singularity Challenge donation drive of the Singularity Institute for Artificial Intelligence (now known as the Machine Intelligence Research Institute), a nonprofit organization that promotes the development of friendly artificial intelligence. He provided half of the $400,000 matching funds for the 2007 donation drive, and as of 2013 the Thiel Foundation had donated over $1 million to the institute. Additionally, he has spoken at multiple Singularity Summits. At the 2009 Singularity Summit, he said his greatest concern is the technological singularity not arriving soon enough.

In December 2015, OpenAI, a nonprofit company aimed at the safe development of artificial general intelligence, announced that Thiel was one of its financial backers.

In September 2006, Thiel announced that he would donate $3.5 million to foster anti-aging research through the non-profit Methuselah Mouse Prize foundation. He gave the following reasons for his pledge: "Rapid advances in biological science foretell of a treasure trove of discoveries this century, including dramatically improved health and longevity for all. I'm backing Dr. [Aubrey] de Grey, because I believe that his revolutionary approach to aging research will accelerate this process, allowing many people alive today to enjoy radically longer and healthier lives for themselves and their loved ones." As of February 2017, he had donated over $7 million to the foundation.

Thiel resided in San Francisco, California, until 2018, when he moved to Los Angeles. He had criticized San Francisco for being "intolerant of conservatives, insular and overpriced". Both Thiel Capital and Thiel Foundation followed him to Los Angeles, but the Founders Fund remains in San Francisco. Mithril's headquarters moved to Austin. Thiel owns homes all over the world, with his main residence in Miami.

Thiel married his long-time partner, Matt Danzeisen, in Vienna, Austria, on Thiel's 50th birthday (October 2017), when he was reported to have proposed to Danzeisen. Danzeisen started his career as an investment banker at Bank of America Securities. By 2007, when the couple were dating, Danzeisen was vice president of BlackRock. By 2021, he was chairman of Bridgetown 1 and Bridgetown 2, sponsored by Thiel Capital and Richard Li's Pacific Century Group. Sam Altman also sat on the board. Danzeisen also participates in other Thiel enterprises related to the family of Li Ka-shing (father of Richard Li), such as the Malta-based EUM. In 2017 Danzeisen was working as head of private investments at Thiel Capital, with a primary focus on North America and Asia. Thiel and Danzeisen have two young daughters, aged five and three as of June 2024, born through a surrogate. Adrian Wooldridge from Bloomberg reported in August 2025 that Thiel had four children. In 2023, in an interview with the Atlantic, Thiel noted that Danzeisen had tried to dissuade him from donating money to Republicans.

In 1995, the Independent Institute published The Diversity Myth: Multiculturalism and the Politics of Intolerance at Stanford, which Thiel co-authored along with fellow tech entrepreneur David O. Sacks, and with a foreword by the late Emory University historian Elizabeth Fox-Genovese. The book is critical of political correctness and multiculturalism in higher education and alleges that it has diluted academic rigor. The authors also argue that, "You don't have diversity when you gather people who look different but talk and think alike."

Thiel and Sacks's writings drew criticism from then-Stanford Provost Condoleezza Rice and then-Stanford President Gerhard Casper in describing Thiel and Sacks's view of Stanford as "a cartoon, not a description of our freshman curriculum", and their commentary as "demagoguery, pure and simple".

In 2016, Thiel apologized for two statements involving the rape crisis movement and date rape that he made in the book.

In spring 2012, Thiel taught the class CS 183: Startup at Stanford University. Notes for the course, taken by student Blake Masters, led to a book titled Zero to One: Notes on Startups, or How to Build the Future by Thiel and Masters, which was released in September 2014.

Derek Thompson, writing for The Atlantic, stated Zero to One "might be the best business book I've read". He described it as a "self-help book for entrepreneurs, bursting with bromides" but also as a "lucid and profound articulation of capitalism and success in the 21st century economy."
