Liz Kennedy is one of the most influential privacy architects in the digital advertising industry, serving as Chief Privacy Officer at IAB Tech Lab where she leads the development of technical standards that enable privacy-compliant advertising across the open web. She is best known for her central role in building the Global Privacy Platform (GPP), a unified framework designed to consolidate and streamline how publishers, advertisers, and technology vendors communicate consumer privacy signals across multiple regulatory jurisdictions including GDPR, CCPA, and emerging U.S. state privacy laws. At IAB Tech Lab, Kennedy works at the intersection of law, policy, and engineering — translating complex and often fragmented regulatory requirements into actionable technical specifications that the entire ad ecosystem can implement. Her work on Consent Management Platforms (CMPs) and the Transparency and Consent Framework (TCF) has been foundational to how the industry operationalizes user consent. She collaborates closely with publishers, DSPs, SSPs, and data companies to ensure that privacy standards are both legally defensible and technically feasible. Kennedy is widely regarded as a bridge between the legal/regulatory world and the technical AdTech community, a rare combination that makes her a sought-after voice on panels, in working groups, and in policy discussions. Her influence extends beyond IAB Tech Lab through her participation in industry coalitions and her contributions to shaping how the ad industry responds to evolving global privacy legislation.
