TikTok’s advertising team is undergoing another big shake-up.

Khartoon Weiss, the lead exec for TikTok’s North American ads business, is exiting the company, four people familiar with the matter told Business Insider.
Weiss, who pitched TikTok’s suite of ad products to marketers onstage at its NewFronts event last month, joined the company almost six years ago from Spotify. She oversaw TikTok’s global agency and accounts teams before being promoted to lead the North America division of the global business solutions team in March 2025, following the departure of advertising head Blake Chandlee.
Digiday first reported on Weiss’ exit.
Weiss’ exit is the latest in a string of advertising and marketing team departures at TikTok.
Zuber Mohammed, TikTok’s global head of consumer marketing, left the company in March. Sofia Hernandez, the global head of business marketing and commercial partnerships, and Rema Vasan, who headed up business marketing in North America, left the company last quarter.
Other teams at TikTok have also seen leadership changes this year, including the company’s content division, which lost its global head of creators, Kim Farrell, in January.
Some of the executive exits have shifted control of North America teams to leaders from Singapore or China. When Chandlee left last year, oversight of the sales team, known as global business solutions, moved to Singapore-based executive Will Liu, for example.
TikTok’s US team restructured in January while forming a new joint venture to transfer certain work, like US user data management, to a separate group that includes Oracle and investment firms MGX and Silver Lake. Its advertising and marketing teams remain under the control of parent company ByteDance.
As part of the structural change, Adam Presser, a trust and safety executive, became CEO of the US joint venture. Presser appeared alongside Weiss at TikTok’s March NewFronts presentation to assure advertisers that the company’s ads experience would not be disrupted amid internal changes.
