Larry Page and Sergey Brin, co-founders of Google, received a $ 2 billion ($ 2 billion) retirement grant from investors on Wednesday.

Google's founders, Big and Brin, announced their resignation on Tuesday from the daily management of parent company Alphabet, each adding $ 1 billion to his fortune, after the company's shares rose 1.8 percent.

They each own 6% of technology giant Google and control Alphabet through private voting shares, according to Bloomberg.

The gains came as investors welcomed the promotion of Sandar Beshay to Alphabet's CEO, replacing Page. This means that the top three US technology companies are no longer led by their founders.

Paige, who is chief executive of Alphabet, and Brin, chairman of the same company, said yesterday that they would remain on the board and as shareholders.

"We would never have held onto management roles when we thought there was a better way to run the company," Bigg and Brin wrote in a post on Google's blog.

The move comes as the technology giant faces increasing regulatory scrutiny, as lawmakers in the United States and Europe question Google's market size and data privacy practices.
