About Evertune

Brian, Ed and Poul started Evertune after years of working together building technology at the intersection of AI and marketing. Ed and Poul first met at AdBrain, where they built a leading edge identity graph using advanced machine learning techniques.

The Trade Desk, where Brian led the commercial and partnerships teams for 11 years, acquired AdBrain in 2017 to power its identity solutions, bringing Ed, Poul and Brian together for the first time. We launched Evertune in April 2024 because we believe that AI is in the early stages of revolutionizing marketing and advertising, and we’re building a company to power that future.
