As of December 2024, Brin is the 7th-richest person in the world, with an estimated net worth of $164 billion, according to the Bloomberg Billionaires Index and Forbes.

He earned his bachelor's degree at the University of Maryland, College Park, following in his father's and grandfather's [4][5] footsteps by studying mathematics as well as computer science.

The program became popular at Stanford, and he discontinued his PhD studies to start up Google in Susan Wojcicki's garage in Menlo Park.

[9] His father is a retired mathematics professor at the University of Maryland, and his mother is a researcher at NASA's Goddard Space Flight Center.

[10][11] The Brin family lived in a three-room apartment in central Moscow, which they also shared with Sergey's paternal grandmother.

[10] In 1977, after his father returned from a mathematics conference in Warsaw, Poland, Mikhail Brin announced that it was time for the family to emigrate.

For the next eight months, without any steady income, they were forced to take on temporary jobs as they waited, afraid their request would be denied as it was for many refuseniks.

[10][12] Brin attended elementary school at Paint Branch Montessori School in Adelphi, Maryland, but he received further education at home; his father, a professor in the department of mathematics at the University of Maryland, encouraged him to learn mathematics and his family helped him retain his Russian-language skills.

[19] Combining their ideas, they began utilizing Page's dormitory room as a machine laboratory, and extracted spare parts from inexpensive computers to create a device that they used to connect the nascent search engine with Stanford's broadband campus network.

As their search engine grew in popularity among Stanford users, it required additional servers to process the queries.

The technology allowed for books and manuscripts‍—‌originally replicated by hand‍—‌to be printed at a much faster rate, thus spreading knowledge and helping to usher in the European Renaissance ... Google has done a similar job.

[29] In October 2023, LTA's 124-meter long flagship, Pathfinder 1, became the largest airship since the Hindenburg to receive clearance for flight testing, permitted over the boundaries of Moffett Field and neighboring Palo Alto Airport’s airspaces, at a height of up to 460 meters.

[31][better source needed] In May 2007, Brin married biotech analyst and entrepreneur Anne Wojcicki in the Bahamas.

[41] The Wall Street Journal reported that a reason for the breakup was a "brief affair" in 2021 between Shanahan and Elon Musk.

[12] Brin is a donor to Democratic Party candidates and organizations, having donated $5,000 to Barack Obama's reelection campaign and $30,800 to the DNC.
