Former senior Google executive Omid Kordestani has been appointed as the new executive chairman of Twitter.
Omid Kordestani, 53, joined Google in 1999 and held various senior roles before leaving a decade later.
He returned last year as Chief Business Officer to advise on Google’s rebranding to Alphabet.
“It’s rare you get to be at a company with an amazing business that’s also transforming the world,” he tweeted. “I’ve had good fortune to be at three: Netscape, @google, and now @twitter.”
“A great chairperson is the first step towards continuing to make our board one of the best in the world, and purpose-built to serve Twitter,” he tweeted.
Twitter had said it would seek an external appointment as chairman in a bid to allay concerns about Jack Dorsey’s dual role as Twitter boss and chief executive of Square, the mobile payments company he founded.
Twitter co-founder Jack Dorsey replaced Dick Costolo, who stepped down in July after five years in the role amid pressure to increase growth.
It is his second stint as Twitter boss, having held the position between May 2007 and October 2008.
Twitter shares rose 0.7% to $29.26 following the announcement.
However, the shares are still down almost 30% from the level at which it floated in late 2013.
Tehran-born Omid Kordestani’s appointment comes a day after Twitter said it was cutting 336 jobs, or about 8% of its global workforce, as part of a restructuring to cut costs.
