Google founders Larry Page and Sergey Brin have handed the day-to-day reins of the company’s largest division to long-time employee Sundar Pichai.

If you don’t know Pichai, an eleven-year Googler and current senior vice president of products, you should get to know him: He’s going to be controlling a business, aptly named Google GOOGL, -1.44% , responsible for more than 98% of future parent company Alphabet’s total revenue.

Deutsche Bank analyst Ross Sandler estimates that the properties under Pichai’s control — including Google’s main Internet businesses, from search and ads to YouTube, Maps, Apps, Android and Play — will generate $59 billion in revenue this year, a 14% year-over-year increase.

That dwarfs revenue from the other Alphabet businesses, such as Google Ventures, Nest Labs and the experimental X division, which Sandler estimates will total $763 million.

Shares of Google were up 4.2% to $691.05 in recent trade after sharply spiking in after-hours trade late Monday following the announcement by Page in a letter to shareholders.

Here are five things you should know about Pichai as he takes on the role of Google CEO:

He is an Ivy Leaguer from India

Pichai, 43, originally from Tamil Nadu, a southeast state in India, had very modest beginnings, having been raised in a two-room apartment that required him and his brother to sleep on the living-room floor, according to a profile in the The Telegraph.

He first attended university in his home country, where he received a degree in technology from the Indian Institute of Technology in Kharagpur. Upon moving to the United States, he obtained a Master of Science from Stanford University and later an MBA from the University of Pennsylvania’s ivy-league-rated Wharton School of Business. At Wharton, he was honored as a Siebel Scholar and a Palmer Scholar, according to reports.

He knows how to navigate corporate politics

The former head of Chrome and Android is well-liked across the company and savvy at managing corporate politics, according to one of his former colleagues, Chris Beckmann, who served as a project manager at Google for several years.

“He avoided making enemies,” Beckmann said in a recent post on Quora. “Google has politics like any other large company, and Sundar navigated those politics to make his team successful while inflicting the least possible damage on any other team.”

He quickly rose through Google’s ranks after launching Chrome

His likability has been one reason for his rapid rise through the ranks at Google. He was initially hired as a product manager, eventually reporting to then-head of product, Marissa Mayer, now CEO of Yahoo Inc. US:YHOO . At the time he was a lead in the launch of Google’s Web browser, Chrome.

Despite a few hiccups in the Chrome launch, he was shortly thereafter promoted to vice president. He was ultimately promoted to senior vice president, taking on increasing oversight over Google products, including Chromebook, Chromecast and Gmail. In 2013, he was additionally handed the reins of Android when Andy Rubin stepped down. For the last year, he was largely viewed as a right-hand man for Page.

“We think Sundar Pichai is extremely capable,” Pacific Crest Securities analyst Evan Wilson said.

He turned down an offer from Twitter four years ago

He has been noticed by other companies as well, including Twitter Inc. TWTR, -0.62% . In 2011, Twitter tried to poach Pichai to oversee products at the microblogging site after then-VP of product Jason Goldman stepped down. According to an AllThingsD article at the time citing unnamed sources, Google gave Pichai a significant pay raise to keep him on board.

His name was recently floated as a potential candidate for the role of CEO at Twitter, and FBR analyst William Bird said his promotion to CEO may have been a tactic by Page and Brin to keep Pichai on staff.

“The new structure offers an important way to promote and retain Sundar Pichai,” Bird said.

In 2014, Pichai was also floated as a potential candidate to fill the CEO role at Microsoft Corp. MSFT, +1.07% after Steve Ballmer stepped down. His leadership skills have been touted by current and former colleagues, including Beckmann, who, in the Quora post, said Pichai was known for his savvy in recruiting, mentoring and retaining talent.

“Sundar’s team of product managers had a reputation as being among the best of the best,” Beckmann said.

He’s been preparing for his promotion for almost a year

In a note to shareholders on Monday, Page said Pichai has “really stepped up since October” 2014, when he took on product and engineering responsibility for Google’s Internet business. “Sergey and I have been super excited about his progress,” Page said.

While the formation of Alphabet has been touted by analysts as a way to increase transparency within Google’s core business, analysts also see Pichai as a fresh-yet-seasoned face to lead the Google core from here. He will report directly to Page.

“With the Alphabet move, GOOG ushers into the spotlight a new cadre of leaders (like Pichai) who will have autonomy over the Internet business,” Cowen analyst John Blackledge wrote in a note to clients.
