Ev Williams, a co-founder of Twitter and the social media business’s former chief operating officer, is stepping down from its board of directors effective at the end of the month, according to documents communicated to the U.S. Protection and Exchange Commission on Friday, first reported by CNBC.
In a series of tweets, Williams addressed the news.
” I’m very lucky to have helped on the
@ s> 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, @ s> jack and @ s> biz for starting this crazy corporation with me–and continuing to make it better and better. And to my fellow members of the security council, brand-new and old–some of “the worlds largest” thoughtful people I’ve ever known .”
Williams, the founder and CEO of online publishing platform Medium and co-founder and marriage at Obvious Undertakings, 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 shut up 3 percent Friday, trading at virtually $32 a piece for a market cap of north of $24 billion.
