Twitter appoints Jack Dorsey as permanent CEO, Dick Costolo resigns from board

It’s official: Jack Dorsey is Twitter’s new CEO.

Twitter’s board has decided to strip the ‘interim’ from his title, officially making him the chief executive of the platform effective immediately. Dorsey, who co-founded Twitter in 2006, will also remain as the CEO of e-commerce startup Square. The move comes nearly a week after Recode first reported the news.

Costolo announced that he’s resigning from the board. He called Dorsey a “calm and thoughtful leader” and blasted the months of rumors circulating about the company, tweeting:

Twitter’s stock is up 2 percent in pre-market trading.
