Ev Wiliams, a co-founder of Twitter and the social media business’s former chief executive officer, is stepping down from its board of directors effective at the end of the month, according to documents submitted to the U.S. Securities and Exchange Commission on Friday, first reported by CNBC.
“I’m very lucky to have served on the
@Twitter board for 12 years (ever since there was a board),” he wrote. “It’s been overwhelmingly interesting, educational—and, at times, challenging… Thank you, @jack and @biz for starting this crazy company with me—and continuing to make it better and better. And to my fellow board members, new and old—some of the most thoughtful people I’ve ever known.”
Wiliams, the founder and CEO of online publishing platform Medium and co-founder and partner at Obvious Ventures, served as Twitter’s chief executive from 2008 to 2010 following Jack Dorsey’s, Twitter’s current CEO, original stint as CEO. Williams was succeeded by Dick Costolo, who after a five-year stint at the helm, relinquished the throne back to Dorsey.
Twitter’s stock closed up 3 percent Friday, trading at nearly $32 a piece for a market cap of north of $24 billion.
