Microsoft, one of the world's largest companies by market cap, is led by Satya Nadella, who succeeded Steve Ballmer as chief executive.
Microsoft announced Nadella as its third chief executive in February 2014. He joined the company in 1992 and held senior roles in its enterprise and cloud businesses before becoming CEO. His appointment followed Ballmer's tenure, which lasted from 2000 until 2014.
Nadella's leadership is strongly associated with Microsoft's emphasis on cloud computing, especially Azure, as well as subscriptions and enterprise services. Microsoft had already begun building those businesses before he became CEO, but cloud services became a particularly important part of the company's strategy during his tenure.
Nadella is sometimes confused with the leaders of other highly valued technology companies. Sundar Pichai leads Alphabet, Tim Cook leads Apple, and Andy Jassy leads Amazon. A company's chief executive and its largest shareholder are not necessarily the same person, and the CEO role can change even when the company remains among the world's biggest by market value.
