Twitter has announced the appointment of former Google executive Omid Kordestani to its board of directors, serving as executive chairman. Twitter’s co-founder, Jack Dorsey, who returned to the permanent role of CEOlast week, said: “A great chairperson is the first step to continuing to make our board one of the best in the world, and purpose-built to serve Twitter.

Kordestani was chief business officer of Google from August 2014 to August of this year, when the company reorganised under its new umbrella corporation, Alphabet, and the executive was sidelined. He has remained on as “senior advisor.” How Kordestani’s role will differ from Dorsey’s own remains to be seen.

Kordestani has also worked as a vice president at Netscape and Hewlett Packard, previously sat on Spotify’s board of directors and was a non-executive at Vodafone until 2014. He was widely praised for his time at Netscape after revenue increased from $88 million to around $200 million in 18 months. However, he had less success at GO Corporation, which folded in 1994.
