Sergey Brin Insider Information

Insider of Alphabet

Sergey Brin is the co-founder of multinational technology company, Google. 

Together with Larry Page, Brin co-founded Google in 1998 as a college research project, and ultimately grew the search engine into one of the most valuable companies in history. Brin and Page maintain controlling shares of Google’s parent company, Alphabet, and rank among the world’s wealthiest people

When Brin was a child, he and his family emigrated from Russia to escape Jewish persecution. While pursuing his Ph.D in computer science at Stanford University, Brin met Page and the duo teamed up on a project to determine the importance of a research paper based on the number of citations in other papers. Realizing they could do the same for web pages, Brin and Page invented the PageRank algorithm. Applying the algorithm to a preliminary search engine run on a makeshift server in their dorm room, Brin and Page recognized their search engine was better than anything currently available. Google launched in 1996, and the resulting traffic caused issues on Stanford’s network.

Brin and Page incorporated Google in 1998 and attempted to sell the search engine to Internet company, Excite, the following year for $750,000. Excite’s CEO turned the offer down, leaving the pair to double down on growing Google themselves. 

By 2001, the graduate school dropouts were overseeing one of the fastest-growing companies in corporate history. After encouragement from investors to bring in more experienced leadership, Brin and Page hired Eric Schmidt to take over as CEO. 

Following Yahoo’s attempt to acquire Google for $3 billion in 2002, Brin and Page took Google public in 2004 with a valuation of $27 billion. The founders created a super-voting Class B stock that only they and a few other Google executives were granted. The structure guaranteed Brin and Page majority ownership in perpetuity, a model that numerous tech companies copied afterward. 

Brin and Page initiated the key acquisitions of mobile computing developer, Android, for $50 million in 2005 and online video platform, YouTube, for $1.6 billion in 2006. In 2008, Brin and Page hired a number of Mozilla Firefox developers to create a better web browser at the suggestion of future Google CEO, Sundar Pichai. The result, Google Chrome, became the most popular web browser in the world. 

In 2011, Page replaced Schmidt as Google’s CEO. With his newfound leadership flexibility, Brin launched Google X the same year. Google’s “moonshot factory” for experimental hardware and long-term projects debuted Google Glass in 2012 in a famous release in which Brin coordinated skydivers wearing the heads-up display device to land on the roof of the building he was delivering the presentation in. 

By 2015, Brin and Page announced the creation of Alphabet, a move that removed the pair from day-to-day management of Google by making them co-CEOs and co-presidents of the holding company. Both founders stepped down from Alphabet’s leadership in 2019.

Brin remains a board member and majority shareholder of Alphabet. The search engine he helped create in his college dorm room handles over 3 billion queries daily giving Google a 90 percent worldwide market share. 

He holds a master’s degree in computer science from Stanford University and a B.S. in computer science and mathematics from the University of Maryland at College Park. Brin received an honorary M.B.A. from Instituto de Empresa and a National Science Foundation Graduate Fellowship.
