Gain Theory

NEW YORK — Gain Theory, the global marketing foresight consultancy, today announced the appointment of Earl Potter to Senior Partner, Client Development Lead and Jayne Oh to Client Engagement Director, effective immediately.

In his new role, Potter will be responsible for directing and overseeing work with key clients ensuring that the consultancy is building and delivering high value actionable insights.

Potter comes to Gain Theory from Maxus, where he led data & analytics for North America. He was instrumental in setting up data marts for the agency’s largest clients and for heading up advanced analytic projects including media mix and attribution studies. He also developed the first geo-spatial analytic methodology designed to provide better overlap between where customers live and where media is being served. Prior to Maxus, Potter held Analytic and Technology leadership roles within Mediabrands, Roundy’s Supermarkets, and Bon Ton Department Stores. He holds a PhD in physical chemistry as well as a master’s degree in management of technology from The Wharton School at the University of Pennsylvania.

“Earl is a true industry pioneer – having implemented data-driven marketing initiatives long before the rest of the industry understood the power of data, much less how to harness it,” said Jason Harrison, worldwide CEO, Gain Theory. “His eclectic background includes stints in military analytics, human resources research, entrepreneurship and physical chemistry which makes him an incredibly unique and valuable talent.”

As Client Engagement Director, Jayne Oh will head up the delivery of all ongoing data management and technology components for Diageo in North America. She will also help to lead Gain Theory’s data and tech strategies.

Oh joins Gain Theory from Maxus where she was responsible for guiding clients on how to maximize their data assets as well as for building out the agency’s reporting and visualization capabilities. She began her career at Accenture, working in various technical roles focused on systems implementation. Oh then joined GroupM where she led a variety of global programs delivering tech solutions to both clients and agency teams as Global Program Director.

“Jayne has unique, much sought-after experience helping some of the largest brands manage, organize and maximize the efficiency of multiple data sets. The right ongoing data management is the foundation from which to deliver the best possible intelligence for faster, smarter decisions and Jayne’s demonstrated skill in this area make her a rare and strategic asset to us and to our clients,” observed Harrison.


Gain Theory is a global marketing foresight consultancy that brings together data, analytics, technology solutions and consumer-insight capabilities. An independent practice within GroupM, it combines WPP’s intellectual capital in media, marketing, data and technology to create a consultancy that helps brands make smarter, faster, predictive business decisions.
