Who became head of Instagram on October 1, 2018?

Adam Mosseri became head of Instagram on October 1, 2018. Facebook announced his appointment shortly after Instagram co-founders Kevin Systrom and Mike Krieger said they were stepping down in September 2018.

Mosseri was an experienced Facebook executive rather than one of Instagram’s founders. He joined Facebook in 2008, worked in product design, later oversaw the News Feed, and became a vice president of product. He had also been named Instagram’s vice president of product in May 2018, making the move to the top role a transition within Facebook’s management structure.

Facebook generally reserved the title “CEO” for founders, so Mosseri was described as Instagram’s head rather than its chief executive. His appointment also marked a major leadership change after Facebook’s 2012 acquisition of Instagram. Sheryl Sandberg, Andrew Bosworth, and Chris Cox were senior Facebook or Meta executives, but none became Instagram’s head on that date.
