Everyone thinks they know who the largest marketing companies in the world are, and I’m sure you know some of the famous agencies like BBDO, Havas or Grey. But would you be surprised if I told you those agencies don’t even crack our top 10?
The landscape of global agencies has become crowded and confusing over the last 10 years. While huge agency networks and holding companies are the vanguard, there has been a convergence of consulting firms and tech giants entering the frame to compete as well as in-house agencies. All of this continues to blur the line between what is considered an agency and who is best suited to help your global marketing, advertising, and digital initiatives.
To bring some clarity to the global agency marketplace, Agency Spotter has put together the 50 largest marketing agencies according to estimated yearly revenue. This list represents the 50 biggest agencies and not the agency networks or groups like WPP, Publicis Group, Dentsu Inc, Interpublic, and Omnicom Group. If you’re looking to find your next marketing partner, keep in mind that the most helpful agency may not be the biggest or most well-known one your budget can afford you… Thankfully, Agency Spotter allows you to search for an agency by size.
