Marketing built on proof, not promises™.

Draw a clear line between your marketing investment and real business outcomes.

What drives us

Truth, trust and transparency are at the heart of everything we do.

Success that’s shared with clients and consumers

We’re committed to doing what’s best for all parties. We always choose what works and what’s right over what’s easy and accepted.

Outcome-based performance

We help clients make marketing decisions that build on each other, so they get more out of their data and tech while reaching (and even exceeding) their goals.

Putting real people at the center

We give brands a view of each consumer as an individual—bridging their online and offline identities to deliver marketing experiences they want.

Privacy by design

Privacy has been our priority for more than 50 years. All our solutions are proactively designed with privacy built in.

Performance transparency

Zero in on your business goals and optimize every interaction to reach them. Then get the hard-and-fast results to prove it.

At the core of Publicis Groupe, we're changing the industry.

In 2019, Publicis Groupe acquired Epsilon in one of the largest acquisitions in marketing history. The event put Epsilon at the center of operations for Publicis around the world and set the stage for us to lead the industry in its own transformation.
