Twitter COO Ali Rowghani Exits

Ali Rowghani has resigned as chief operating officer of Twitter, about eight months after the social-media company went public.

Rowghani will continue to be a Twitter employee, acting as a strategic adviser to CEO Dick Costolo, the company said in a filing with the Securities and Exchange Commission Thursday. Twitter said it does not intend to hire a replacement for Rowghani, with all of his duties to be assumed by other execs.

Twitter’s shares shot up 73% when the company launched its IPO in November, but since then the stock has dropped about 21%. The company has posted revenue gains but Wall Street has been concerned that Twitter’s user growth is slower than expected.

Rowghani joined Twitter in March 2010 after nine years with Pixar Animation Studios, where was CFO and SVP of strategic planning for Pixar, Disney Animation Studios and Disney Toon Studios.

“Goodbye Twitter. It’s been an amazing ride, and I will cherish the memories,” Rowghani tweeted Thursday morning.

Rowghani’s departure comes after SVP of engineering Chris Fry stepped down last month and VP of product Michael Sippey resigned in January.
