Sergey Brin co-founded Google alongside Larry Page in 1998, and more than two decades later he’s still one of the most influential — and richest — people in tech. Officially, he stepped back from day-to-day leadership years ago. Unofficially, he’s been increasingly visible again as Alphabet pushes hard into AI with Gemini. Here’s everything on his age, education, career, net worth, and personal life, including his marriages to Anne Wojcicki and Nicole Shanahan. Who Is Sergey Brin? Sergey Brin is a Russian-American computer scientist and entrepreneur best known as the co-founder of Google, now part of Alphabet Inc. He built the company’s original search algorithm, PageRank, together with Larry Page while both were PhD students at Stanford. Brin served as President of Alphabet until 2019, when he and Page stepped back from executive roles, though he’s remained an active board member and, more recently, a hands-on presence in Google’s AI efforts. Sergey Brin’s Age and Early Life Sergey Brin was born on August 21, 1973, in Moscow, in what was then the Soviet Union, making him 52 years old as of 2026. His family emigrated to the United States when he was six, settling in Maryland, partly to escape the antisemitism his father, a mathematician, faced in the Soviet academic system. Brin’s father went on to become a mathematics professor at the University of Maryland, and his mother worked as a researcher at NASA — a household that pushed him toward math and computing from an early age. Sergey Brin’s Education University of Maryland — Bachelor’s degree in computer science and mathematics, graduating with honors in 1993 Stanford University — Enrolled in the PhD program in computer science on a National Science Foundation fellowship. It was at Stanford in 1995 that he met fellow PhD student Larry Page, and the two began collaborating on the research project that became Google. Brin took a leave of absence from the program in 1998 to run Google full-time and never returned to finish the doctorate. Sergey Brin’s Career Building Google 1995–1998 Brin and Page’s Stanford research project focused on ranking web pages by the links pointing to them, an approach that became the PageRank algorithm. They founded Google in a Menlo Park garage in September 1998. Google’s Head of Technology 1998–2011 As Google grew from a startup into the dominant global search engine, Brin held the title of President of Technology, overseeing the company’s engineering and technical strategy through its 2004 IPO and its expansion into products like Gmail, Google Maps, and Android. Director of Special Projects and Google X 2011–2015 In 2011, Brin stepped back from day-to-day technology leadership to focus on “special projects,” including what became Google X now simply X , the company’s moonshot lab responsible for projects like Waymo self-driving cars and Google Glass. President of Alphabet 2015–2019 When Google reorganized under the Alphabet holding company in 2015, Brin became President of Alphabet, a role focused on the company’s long-term, higher-risk bets outside core search and advertising. Stepping Back, Then Stepping Back In 2019–2025 In December 2019, Brin and Page both stepped down from their executive roles, handing the Alphabet CEO title to Sundar Pichai, though both remained board members and controlling shareholders through Alphabet’s dual-class share structure. For several years, Brin kept a low public profile. That changed as AI became Google’s central battleground: Brin has since been reported to be personally involved https://officechai.com/ai/ai-pulled-me-out-of-retirement-google-co-founder-sergey-brin/ in Gemini’s development, has made rare public appearances alongside Google engineers https://officechai.com/ai/google-co-founder-sergey-brin-is-sitting-and-coding-with-gemini-engineers-ceo-sundar-pichai/ , and has spoken publicly about the company’s early AI missteps https://officechai.com/ai/we-fully-intend-that-gemini-be-the-first-agi-google-co-founder-sergey-brin/ and its renewed urgency around the technology. Alphabet Today As of 2026, Brin remains a director of Alphabet and, together with Page, controls the majority of the company’s voting power through Class B shares, even though both own a minority of total equity. He continues to be one of the most closely watched voices in how Google approaches the AI race against OpenAI and other rivals. Sergey Brin’s Net Worth Sergey Brin’s net worth is one of the largest and most-watched in the world, fluctuating daily with Alphabet’s stock price. Forbes’ real-time tracker has placed him in the range of roughly $240–260 billion through much of 2026, consistently ranking him among the world’s three or four richest people, alongside Larry Page, Elon Musk, and Jeff Bezos. His fortune is built almost entirely on his Alphabet shareholding, split across Class A, B, and C stock, plus a smaller allocation of cash, private investments, and philanthropic vehicles. Because it’s tied to a publicly traded stock, this figure moves constantly — treat any specific number as a snapshot rather than a fixed figure. Brin has also given away a significant amount of stock over the years, including large donations toward Parkinson’s disease research through the Sergey Brin Family Foundation — a cause with personal significance, as he carries a genetic mutation linked to elevated Parkinson’s risk. Sergey Brin’s Personal Life: Wives and Relationships Anne Wojcicki married 2007–2015 Brin married Anne Wojcicki, who went on to co-found the genetic testing company 23andMe, in 2007. The couple had two children together, a son and a daughter, before separating in 2013 and finalizing their divorce in 2015. Reporting at the time linked the split to Brin’s relationship with a Google employee, which he has not publicly commented on in detail. Nicole Shanahan married 2018–2022 Brin began seeing attorney and entrepreneur Nicole Shanahan around 2015, and the two married in 2018. They had a daughter together, and their marriage became a significant part of Shanahan’s own public profile before she later became known for her political activities. Brin filed for divorce in 2022, citing irreconcilable differences, and the divorce was finalized that year with the couple sharing custody of their daughter. Media reports at the time linked the split to allegations that Shanahan had a brief relationship with Elon Musk in late 2021 — a claim both Shanahan and Musk have publicly denied, with Shanahan describing the rumors as personally painful and inaccurate. Shanahan later made a foray into politics, and was Robert Kennedy’s running mate in his 2024 presidential campaign. Gerelyn Gilbert-Soto dating since 2023 Since 2023, Brin has been in a relationship with Gerelyn Gilbert-Soto, a wellness influencer and health coach. The relationship became widely publicized in 2026 after the two appeared together at a White House dinner for tech executives, where President Donald Trump referred to her as Brin’s girlfriend. The couple has since been seen together at other high-profile events. Children Brin has three children in total: a son and a daughter from his marriage to Anne Wojcicki, and a daughter from his marriage to Nicole Shanahan. FAQs How old is Sergey Brin?
