Twitter officially named Jack Dorsey as permanent CEO

On Monday, the board of directors of Twitter officially appointed its co-founder Jack Dorsey as permanent CEO. He will no longer serve as Chairman, but will remain a member of the company’s Board. He also remains as CEO of Square.

The board of directors said Mr. Dorsey has extensive experience with technology companies, and they believe that he can revive Twitter.

Mr. Dorsey said he will focus on building teams that move fast and learn faster, and they will work forward on making Twitter easy to understand by anyone in the world. He also promised to do whatever it to ensure the company’s growth.

The board of directors also appointed Adam Bain as chief operating officer. Gartner analyst Brian Blau commented that the appointment of Mr. Dorsey as CEO and Mr. Bain as COO may be a good partnership if both executives perform well in their roles.

“If Adam can execute, and Jack can come in and focus on the next thing, the next product—that is a good relationship,” said Blau.

Prince Alwaleed previously criticized the management of Twitter, and he was against Mr. Dorsey replacing Dick Costolo, when he stepped down as CEO in June. The Saudi Prince said Twitter needs a new leader with extensive marketing experience, and Mr. Dorsey should focus on managing Square.
