• Insider is compiling its annual adtech list that honors the companies transforming digital advertising.
• The list focuses on public and private companies that made the biggest impact in the industry.
• Submit your nominations by November 20

We're seeking nominations for Insider's annual list of the hottest adtech companies.

The list focuses on companies that drove the biggest moves in digital advertising this year, from helping companies deal with the death of third-party cookies, capitalizing on the growth in ad-supported streaming TV, and spinning up new retail media networks. 2023 was an especially tough year, as many firms had to consistently prove their value to clients, as it was tough for adtech firms to raise money, and advertisers cut spend due to economic volatility.

As in previous years, we plan to publish a list of the hottest adtech companies that are driving change with publishers, agencies, retailers, and brands and solving problems in new ways.
