Facebook has named Adam Mosseri, a 10-year veteran at the company, as the new chief executive of Instagram.
The appointment comes after the photo-sharing app's co-founders resigned last week without giving a clear reason.
Instagram founders Kevin Systrom and Mike Krieger announced Mosseri's appointment on the company blog on Monday.
Mosseri was named as Instagram's head of product in May. He began as a designer at Facebook and most recently led its news feed.
The founders sought to reassure users that he will "hold true" to Instagram's values and community.
