Imogen Coles

Imogen Coles is a senior data and media strategy executive operating within WPP's GroupM network, where she has built a reputation for translating complex data capabilities into actionable media and advertising strategies for major brand clients. Her work sits at the intersection of audience intelligence, programmatic advertising, and data governance — areas that have become increasingly critical as the industry navigates signal loss, privacy regulation, and the deprecation of third-party cookies. Coles has progressed through roles of increasing seniority within the WPP and GroupM ecosystem, developing deep expertise in how data assets can be activated across the programmatic supply chain. She has been involved in shaping how GroupM approaches first-party data strategies, identity resolution, and the application of data clean rooms and privacy-preserving technologies for clients operating at scale. As a practitioner-leader, she is recognized for her ability to work across agency, client, and technology partner relationships, helping to align data strategy with measurable business outcomes. Her influence is primarily felt through client work and internal capability building rather than public-facing thought leadership, though she has contributed to industry conversations around data ethics and responsible media activation.
