Mediate.ly was built to serve a need that we experienced in the market while working with programmatic vendors at our sister organization, Primacy – a digital-first agency providing best-in-market strategy, creative, and analytics to Fortune 500 companies. Our mission is to address that need by delivering programmatic with greater insights, access to seasoned leaders, and our game-changing fraud-free guarantee. In short, programmatic with a difference.

About – Our Story

Our Story

For years, we tried to procure programmatic for the brands our agency served. What we found was frustration – programmatic just wasn’t being served with the passion and integrity we felt our clients deserved. So we started mediate.ly, determined to excel where others had fallen short. Now you can enjoy programmatic with the mediate.ly difference. One-on-one collaboration. A generous fraud-free guarantee. And some of the best minds in the industry, unearthing powerful insights and helping you strategically navigate all that machine learning has to offer.
