Twitter co-founder Biz Stone said Tuesday that he’s returning to the tech firm to guide the company’s culture.
In a blog post published on Medium, Stone said he’s not replacing any employee at Twitter but he’ll play a role in helping the company move forward.
“It’s important that everyone understands the whole story of Twitter and each of our roles in that story. I’ll shape the experience internally so it’s also felt outside the company,” he wrote.
Stone worked at Twitter for about six years before leaving the San Francisco company in 2011 to start blogging site Medium with Evan Williams, another Twitter co-founder.
He then went on to found Jelly, a search engine that lets users ask questions and crowdsource answers.
In March, visual bookmarking site Pinterest said that it was acquiring Stone’s company for an undisclosed amount. He then joined Pinterest as a special adviser to co-founder and Chief Product Officer Evan Sharp.
Stone is the second co-founder to return to the struggling tech firm, which has faced layoffs and a string of executive departures. Twitter co-founder Jack Dorsey is running the social media firm as its CEO while also leading mobile payment company Square.
“There’s something about the personality of a company that comes from the folks who start it. There’s a special feeling they bring with them. Jack coming back was a big step forward,” Stone wrote.
Twitter stock is up 2 percent to $19.65 after the news.
