The executive - who is now CEO of both Google and its parent company after the duo decided to step down from their respective roles - has revealed the tech giant will look to the future with the goal of "tackling big challenges through technology".
Taking to social media following this announcement earlier this week, he tweeted: "I'm excited about Alphabet's long term focus on tackling big challenges through technology.
"Thanks to Larry & Sergey, we have a timeless mission, enduring values and a culture of collaboration & exploration - a strong foundation we'll continue to build on."
The pair revealed that they will relinquish their roles as Alphabet's chief executive officer and president respectively but they will remain on the board of Google's parent company
They wrote in a letter to shareholders: "With Alphabet now well-established, and Google and the Other Bets operating effectively as independent companies, it's the natural time to simplify our management structure.
"We've never been ones to hold on to management roles when we think there's a better way to run the company. And Alphabet and Google no longer need two CEOs and a President.
"Going forward, Sundar will be the CEO of both Google and Alphabet. He will be the executive responsible and accountable for leading Google, and managing Alphabet's investment in our portfolio of Other Bets.
"We are deeply committed to Google and Alphabet for the long term, and will remain actively involved as Board members, shareholders and co-founders. In addition, we plan to continue talking with Sundar regularly, especially on topics we're passionate about!
"Sundar brings humility and a deep passion for technology to our users, partners and our employees every day. He's worked closely with us for 15 years, through the formation of Alphabet, as CEO of Google, and a member of the Alphabet Board of Directors.
"He shares our confidence in the value of the Alphabet structure, and the ability it provides us to tackle big challenges through technology. There is no one that we have relied on more since Alphabet was founded, and no better person to lead Google and Alphabet into the future."
