Sergey Brin Bankrolls Fight Against California Wealth Tax
Google co-founder Sergey Brin seeded a $25 million war chest and joined a tech-elite campaign to defeat California's proposed 5% billionaire wealth tax.

Sergey Brin is an American computer scientist and entrepreneur who co-founded Google, the internet search company that reshaped how the world finds and organizes information. Together with Larry Page, he built one of the most influential technology enterprises of the modern era.
Brin was born in Moscow to a Jewish family that emigrated to the United States when he was six years old, escaping persecution in the Soviet Union. His father became a mathematics professor and his mother a researcher, and Brin grew up in Maryland surrounded by science and computing. He studied mathematics and computer science at the University of Maryland, then pursued graduate study at Stanford University. It was at Stanford that he met Larry Page, and the two doctoral students began collaborating on a research project to analyze the structure of links across the World Wide Web.
Their research produced a search algorithm called PageRank, which ranked web pages by their relevance and the importance of the pages linking to them. This approach proved dramatically more effective than existing search tools, and in 1998 Brin and Page formally founded Google, operating at first out of a rented garage. The company grew rapidly, distinguished by the speed and accuracy of its results and by an advertising model that turned search into an enormously profitable business.
Under Brin and Page's direction, Google expanded far beyond search into email, mapping, mobile operating systems, video, cloud computing, and digital advertising. Brin took particular interest in special projects and emerging technologies, helping to shape the company's culture of ambitious, experimental engineering. Google's 2004 stock market debut made its founders billionaires and established the firm as a defining force of the internet age.
In 2015, Google reorganized into a holding company called Alphabet, with Brin serving as president. The new structure separated the core search and advertising business from more speculative ventures, often called "moonshots," housed in a division known as X. Brin was closely involved with these efforts, which explored areas such as self-driving cars, internet-delivering balloons, and wearable computing, including the early Google Glass project. He also took a personal interest in scientific philanthropy, funding research into neurodegenerative disease after learning he carried a genetic marker associated with elevated risk.
In 2019, Brin stepped back from day-to-day management when he and Page relinquished their executive roles at Alphabet, though both retained controlling influence through their shareholdings and board positions. In subsequent years Brin re-engaged with the company's work in artificial intelligence, a field he has described as one of the most consequential developments of his lifetime.
Beyond Google, Brin has pursued interests ranging from aviation and airship development to gymnastics and adventure travel. Known for an informal, intellectually playful manner, he has consistently championed the idea that technology should tackle large, difficult problems. As one of the architects of modern internet search, he occupies a central place in the history of computing, and his fortune ranks him among the wealthiest people in the world. His legacy is inseparable from the way billions of people now access knowledge every day.
