Twitter CEO Leaves Role As UK Director Two Days After Dissolution Of TweetDeck

twitter icon marketing landTwo days after the May 7 dissolution of TweetDeck, Twitter CEO Dick Costolo resigned from his role as UK Director. TweetDeck’s failure to file 2011 accounts led to its forced dissolution by Cardiff-based Companies House, followed by Costolo stepping away from the role of UK Director on May 9.

Dublin-based accountant Laurence O’Brien was selected to takeover Costolo’s UK Director role, and will serve alongside current UK. Directors Alex Macgillivray and Ali Rowghani. Macgillivray also holds the role of Twitter’s general counsel and head of trust, while Rowghani is Twitter’s COO. O’Brien has been with Twitter since 2011 and most recently served as Twitter’s Dublin controller.

Since Twitter’s acquisition of TweetDeck in 2011, Costolo and Macgillivray both served as TweetDeck directors. The dissolution was part of Twitter’s strategy to bring the complementary company further into its fold. According to a May 6 article in the The Guardian, a Twitter spokesperson confirmed, “TweetDeck the product continues to thrive as part of Twitter, but the old company has been dormant for some time, with no outstanding liabilities; hence our agreement with the move to dissolve it.”

Twitter continues to incorporate TweetDeck’s functionality, while developing updated web-based versions of the application.
