Sergey Brin
Co-Founder at Alphabet / Google
About
Sergey Brin co-founded Google with Larry Page in a Stanford dorm room in 1998, building it from a search engine research project into the most dominant technology company of the internet era. Google's PageRank algorithm — based on Brin and Page's Stanford PhD research — transformed how humanity accessed information. Under their leadership, Alphabet grew to encompass YouTube, Android, Google Cloud, Waymo, DeepMind, and dozens of moonshot projects. Brin led Google X, the company's secretive research lab that developed self-driving cars, Google Glass, and Project Loon.

The Algorithm That Organized the World's Information
Sergey Brin emigrated from the Soviet Union to the United States at age six, earned degrees from Maryland and Stanford, and in 1998 co-founded Google with Larry Page based on their PhD research into web link analysis. PageRank — the algorithm that ranked search results by the number and quality of links pointing to a page — was conceptually simple but transformative: it made the internet navigable for ordinary people, and Google's clean, ad-supported interface made it the default gateway to human knowledge.
Google went public in 2004, reorganized as Alphabet in 2015, and grew into one of the most valuable companies in history. Along the way, it built the world's most popular mobile operating system (Android), video platform (YouTube), email service (Gmail), browser (Chrome), and cloud infrastructure. Brin and Page's original mission — to organize the world's information — proved to be among the most consequential commercial ambitions ever articulated.
Moonshots and the X Factor
While Page focused on Alphabet's core businesses, Brin led Google X (later just X), the company's secretive 'moonshot factory' tasked with inventing radical new technologies. Under his direction, X developed Waymo (self-driving cars), Project Loon (internet-beaming balloons), Google Glass, and early work on delivery drones and life sciences through Verily. Many of these projects failed commercially, but the R&D pipeline kept Alphabet at the frontier of emerging technology.
Brin stepped back from day-to-day management of Alphabet in 2019, but his influence endures in the company's culture of ambitious, research-driven innovation and its willingness to invest in long-term bets that may not pay off for decades. His personal fortune, built almost entirely on Alphabet stock, makes him one of the wealthiest people who has ever lived.
