Snapchat’s head of content has stepped down from the position after five years to “take some time off to recharge” before moving on.

Nick Bell, Snapchat’s VP of content, called time on his tenure with the multimedia messaging app in a memo sent to staff, seen by The Hollywood Reporter. He will leave at the end of the year.

With Bell’s departure, Snapchat’s newly-appointed chief strategy officer Jared Grusd will take charge of the content division. Grusd, most recently the CEO of HuffPost, was recruited to replace Imran Khan last month. Meanwhile, Sean Mills, head of original content, and David Brinker, head of content business and corporate development, will continue in their current roles.

Bell joined Snap during early days in order to help build out its Discover section. He was tasked with helping media partners produce original content for the platform. However, it’s not known how well the Discover section does within the app and Bell never gave an indication as to why he has chosen to leave.

“We have built Discover into a world-leading media platform,” said Bell in the Memo. “We have established vertical video as the industry standard, built hugely successful partnerships with some of the world’s best media companies and storytellers, produced incredible stories, launched a fantastic slate of Original Shows and built a robust advertising business. This experience has been incredibly rewarding and an absolute blast. I leave now with amazing memories, many lifelong friendships, and a huge amount of excitement for the future of Snap.”
