Early Life and Education

Sergey Brin was born on August 21, 1973, in Moscow, in the former Soviet Union. His parents were mathematicians, and his father later became a mathematics professor in the United States.

When Brin was six years old, his family moved to America. He eventually studied mathematics and computer science at the University of Maryland.

Later, he joined Stanford University for graduate studies in computer science. This decision became an important turning point in his life.

At Stanford, Brin met another computer science student, Larry Page. Their meeting eventually led to one of the most valuable partnerships in technology history.

How Sergey Brin Built Google

Brin and Page began exploring better ways to organize information on the growing internet.

Together, they developed PageRank, an algorithm that helped rank web pages based on their links and importance. Their early search project was initially known as BackRub.

In 1997, they registered the Google.com domain. A year later, Google Inc. was officially incorporated.

The company started with a small team and operated from a rented garage in Menlo Park. An early investment included a $100,000 check from Sun Microsystems co-founder Andy Bechtolsheim.

Google then grew rapidly. Its biggest turning point came in 2004, when the company went public. The IPO raised around $1.67 billion and valued Google at approximately $23 billion.

The public offering turned Brin and Page into multibillionaires while they were still very young.

Bonus Point: Sergey Brin became a billionaire at just 30 after Google’s 2004 IPO. The company’s public offering quickly transformed Brin and Larry Page from young entrepreneurs into multibillionaires.
