An introduction to Parag Agrawal, Twitter’s new CEO

Twitter has a new CEO: Parag Agrawal, who’ll be taking over for Twitter co-founder Jack Dorsey, the longest-serving chief executive in the company’s 15-plus-year history.

Agrawal isn’t the most well-known of names either inside or outside of Twitter. He’s been with the company for over a decade, though, working his way up from an engineer to become its top executive (and a close friend of Dorsey’s).
