In 2021, several high-profile successors were announced. Jack Dorsey stepped down as CEO of Twitter, having co-founded the company himself 15 years earlier. He passed the reigns to the relatively unknown Parag Agrawal, although Agrawal has worked at Twitter for 10 years, most recently as Chief Technology Officer. A young successor at 37, but with many years of internal experience and perhaps coaching from Dorsey himself, made Agrawal a 'safe' choice in the eyes of shareholders. The new CEO will continue to deliver on Twitter's previously announced strategy. A low-key, internal successor to continue with an established plan and provide a secure platform for future growth. Agrawal will also need to tackle some tricky political challenges linked to Twitter's policies on moderating controversial content.
