The world’s first media agency. Built to challenge the average.
Carat helped establish the practice of media planning and buying. That pioneering spirit still defines us, but our purpose is not to celebrate the tools of media. It is to use the craft of media to engineer lasting brands and create measurable value for clients.
As media becomes more automated, fragmented and shaped by algorithms, brands risk becoming easier to deliver but harder to distinguish. Carat helps brands define and amplify what makes them valuable. We combine human judgement with data, technology, culture and disciplined execution, connecting global capability with local relevance to turn intentional difference into growth.

Difference Engineered. Built on the craft of media.
