Epsilon Integration Central to Publicis Groupe Growth Strategy

Publicis Groupe has significantly advanced the integration of Epsilon, a data and marketing company acquired just over a year ago. The Epsilon PeopleCloud product suite is now utilized in more than half of Publicis Groupe's top 30 client accounts, including major brands such as Kraft Heinz and McDonald's.

The integration has seen Epsilon's technology successfully combined with the Groupe's existing infrastructure. This synergy has reportedly supported the company's new business momentum, contributing to significant wins with clients like Novartis and Disney. Epsilon has also been linked with Publicis Sapient's digital business transformation strategies and Publicis Health's data solutions.

Epsilon's CORE ID technology, built on over 200 million consumer profiles, is positioned as a key asset for marketers navigating the deprecation of third-party cookies and evolving privacy regulations. The company has previously been recognized for its identity resolution capabilities by Forrester Research.

Arthur Sadoun, Chairman and CEO of Publicis Groupe, stated that Epsilon's central role enables the company to help clients build first-party data and regain control over customer relationships. Epsilon PeopleCloud provides proven data and technology platforms for managing and connecting client data assets.
