• TikTok advertising executive Khartoon Weiss is leaving the company.
• Weiss, who spent almost six years at TikTok, oversaw its North America ads business for the past year.
• Weiss is one of several advertising and marketing execs to leave TikTok this year.

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.

Pump problems

Surging gas prices are already wreaking havoc on the economy.

The Iran war has sent oil prices skyrocketing, with the impact being acutely felt at the pump. The average price of gasoline jumped to $3.63 a gallon on Friday, according to AAA, up from $2.93 last month before Middle East tensions escalated.

Gas is now above $3 a gallon in every US state for the first time since 2023. (BI's Dan DeFrancesco and Joe Ciolli broke down what happens next for oil prices in a recent live Q&A).

What started as oil-market jitters is now hampering household budgets and impacting everything from gig work to office attendance.

Uber and Lyft drivers told us they're getting more selective about which rides they accept as gas prices rise. That's because Uber and Lyft control fares, meaning drivers can't raise prices when their operating costs go up. Some gig drivers are rejecting shorter, lower-paying trips that burn fuel and instead are chasing longer fares that make the math work.

Meanwhile, EV drivers are having a moment. As gas-powered drivers wince at the pump, electric vehicle owners are taking what some have called a "victory lap." Charging costs haven't surged in step with oil prices. This is giving EV drivers, including those on rideshare platforms, a meaningful cost advantage.

Higher gas prices are also playing a role in the return-to-office debate. For people who drive to work, pricier fill-ups mean less money in their pockets for everything else.

"When gas prices spike, commuting effectively becomes a pay cut," one chief operating officer told us.

While a few employers say they're softening their RTO stances amid rising gas prices, the vast majority are unlikely to change their in-office requirements, particularly in a cooling job market where many workers lack the leverage to push back.

Still, average gas prices are a far cry from their record high above $5 a gallon in June 2022, months after the Russia-Ukraine war began.

But the latest increase is a reminder of how quickly surging gas prices can ripple through the economy.
