TikTok for Business has partnered with ADWEEK to present the 2026 Fastest Growing Agencies list.
As the inaugural presenting sponsor of the Fastest Growing Agencies list, TikTok for Business will partner with ADWEEK to host a curated event during ADWEEK House: Advertising HQ on Monday, Oct. 5 at 5 p.m. ET.
The event, taking place at Gary’s Loft in New York City, will feature two panels. The first will showcase some of ADWEEK’s 2026 Fastest Growing Agencies, and the second will host TikTok’s top media buying agencies, judged as part of the company’s TikTok Media Buying Excellence Awards.
The event will conclude with a cocktail reception with an open bar and light bites.
The Fastest Growing Agencies list recognizes global agencies large and small whose industry presence is on the rise. These agencies stand out among their competitors by achieving notable growth over the past three years.
This year, there are 72 agencies on the Fastest Growing Agencies list. Nashville-based independent agency The Mayor tops the rankings, with 650% year-over-year revenue growth, followed by digital agencies Stitch (601%) and Siberia (316%).
