Sergey Brin is a computer scientist and entrepreneur. He met Larry Page at Stanford University, and the two created a search engine that would sort web pages based on popularity. Google became the most popular search engine in the world after launching in 1998, its overwhelming success turning the co-founders into billionaires. Brin and Page later became president and CEO of Google's parent company, Alphabet, before they stepped down from their roles in December 2019.
