Jodie Sangster

Jodie Sangster is a globally recognized leader in data strategy, identity resolution, and privacy-compliant marketing, currently serving as Global Head of Data & Identity at GroupM, the world's largest media investment group. In this role, she shapes how one of advertising's most powerful organizations approaches data governance, first-party data strategy, and the post-cookie identity landscape across its global network of agencies including Mindshare, Wavemaker, and EssenceMediacom. Sangster built her reputation over more than a decade as CEO of ADMA (Association for Data-driven Marketing & Advertising) in Australia, where she became a defining force in shaping industry standards around data ethics, consumer privacy, and marketing technology adoption. Under her leadership, ADMA became a leading voice in advocating for responsible data practices and helped shape Australia's evolving privacy regulatory framework. She is widely credited with elevating the conversation around data governance from a compliance checkbox to a strategic business imperative. A sought-after speaker and thought leader, Sangster has represented the advertising and marketing industry at government consultations, international conferences, and cross-industry working groups. Her expertise spans the full spectrum of data-driven marketing — from technical identity solutions and clean rooms to regulatory compliance and consumer trust — making her one of the few executives who can credibly bridge the gap between policy, technology, and commercial strategy.
