We help brands deliver marketing that puts people first.

Epsilon provides the data, technology and services that the world’s top brands need. We help marketers understand consumers, engage them with one harmonized voice across channels, and learn from each interaction—all at an individual level.

Marketing shouldn’t talk at consumers: It should have a conversation with each of them.

We believe every interaction with a brand should have value. That’s why we help brands engage in a conversation with each consumer that’s relevant in the moment and evolves over time. Here’s how it works.

Know what each person wants

Only Epsilon knows what a brands’ potential customers want, what they buy, where to find them and when to engage them.

Be relevant in the moment and stay relevant as each person changes

We help brands understand where and how often to deliver messages to each person (and where not to) and how much to spend based on the likely performance and ultimate potential—in the moment and over time.

Personalize every message across every channel

Powered by AI and person-first identity, our platform recognizes each person in every channel, dynamically creates a relevant message for each one, and captures what a brand learns to inform the next message.

All of this done at incredible scale.

Epsilon solutions support all aspects of marketing and advertising, built on a foundation of consumer identity, AI and creative decisioning at incredible scale.
