Our Story

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. We are driven every day to deliver a better quality of life – for our clients, for consumers, and for one another.

Through omnichannel advertising, powered by AI and smart marketers, today we deliver and optimize all media based on how consumers consume it. Our people are curious marketers, passionate learners and humble in their approach. Smoke and mirrors don’t exist here. This is marketing, reimagined.
