About

Sergey Brin is a computer scientist and the co-founder of Google. As a Stanford graduate student he was assigned to show Larry Page around campus in 1995, and the two went on to build a link-based search engine, first called BackRub, that became Google.Source [1]Source [2]

Brin was Google's President and Chairman of the Board from September 1998 to July 2001, President, Technology from 2001 to 2011, and President from May 2011 to October 2015. When Google reorganized under the Alphabet holding company in October 2015 he became Alphabet's President.Source [3]Source [4]

He stepped back from the President role in December 2019, when Sundar Pichai became CEO of both Alphabet and Google. He later returned to Google's offices and has worked with researchers on the company's Gemini AI models, without an executive title according to press reports.Source [5]Source [3]Source [6]Source [7]

He remains an Alphabet director and Executive Committee member and held 25.3% of total voting power as of April 6, 2026; shareholders re-elected him on June 5, 2026.
