TikTok Names ByteDance Finance Chief As New CEO

TikTok has named Shou Zi Chew, chief financial officer of parent company ByteDance Ltd., to lead the buzzy short-form video app, in a reshuffling that attempts to stabilize the leadership ranks of the fast-growing company.

Mr. Chew is stepping in as CEO of TikTok, while also continuing as ByteDance’s finance chief, the company said in a blog post Friday.

He replaces Vanessa Pappas, a former executive of Alphabet Inc.’s YouTube who will shift into an operating chief role at TikTok. She became TikTok’s interim CEO in August after the abrupt resignation of former Walt Disney Co. executive Kevin Mayer. The company said Ms. Pappas will maintain her current responsibilities including managing TikTok’s key operations.

Mr. Chew will steer TikTok at a time of growing influence for the social-media platform, where users can post short videos and scroll endlessly through other viral videos. He joined ByteDance last month after working at Xiaomi Corp. since 2015 and spent most of his tenure with the Beijing-based smartphone maker as finance chief.
