Twitter Inc. co-founder Biz Stone said he’s rejoining the company six years after he left, becoming the second creator to return to help revive the struggling social-media service.

In his new role, Stone will be focused on company culture, and he’s not replacing another executive or filling a vacancy, he said Tuesday in a post on Medium. He was invited back to Twitter by Chief Executive Officer Jack Dorsey, another co-founder, who returned in 2015 after also stepping away for years. Twitter shares jumped on the news.
