Sean Reardon

Chief Executive Officer

As CEO, I am responsible for defining and driving the vision, strategy, and execution of Epsilon’s leading technology, data and services so that we consistently deliver business results for both our clients and our company. It is my duty to galvanize and motivate Epsilon’s global team of over 8,000 who leverage technology, data and services to help the world’s top brands harmonize customer engagement across paid, owned and earned marketing channels.

With over two decades of leadership experience in advertising and marketing technology, expertise across numerous client categories, and high comfort working with Connected Media peers and across Publicis Groupe, I am confident Epsilon can shape the industry and reach new heights both as a company and as a critical ingredient in Publicis Groupe’s leading suite of capabilities.

My Philosophy: Embrace change as the inevitable, an opportunity to keep shaping, defining, and redefining ourselves and the industry around us.

By leveraging all of Epsilon’s capabilities and solutions, we help our OEM and dealer clients more effectively manage their customer relationship and deliver a strong ROI on marketing dollars spent.

My philosophy: I’m a straight shooter and I believe our clients desire full transparency with “no surprises”. Client engagements boil down to personal relationships and trust. Our clients trust us to do a job, and, in turn, we must do everything in our power to do it flawlessly.
