Satya Nadella, from computer science student to Microsoft $3T CEO

• Satya Nadella became only Microsoft’s third CEO nearly a decade ago.
• The former engineer reformed corporate culture and fostered growth through innovation and partnerships.
• Microsoft is worth more than $3 trillion, but still trails Apple’s valuation.

When Satya Nadella took over as CEO of Microsoft on February 4, 2014, the company was in trouble.

Windows 8 was a disaster. Microsoft employees were constantly fighting behind the scenes for supremacy. And all the while, consumers and developers alike have lost faith in the company co-founded by Bill Gates.

How times have changed.

In January, as Nadella neared a decade at the helm, Microsoft overtook Apple to become the world’s most valuable public company at more than $3 trillion, though Apple has since regained the crown.
