Jess Lis is a key operational leader at the Media Rating Council (MRC), the industry body responsible for setting and enforcing measurement standards across digital and traditional advertising. As Managing Director, she oversees the accreditation process that validates measurement services used by advertisers, agencies, and media companies, making her a central figure in ensuring the integrity and reliability of advertising metrics across the ecosystem. Her work at the MRC places her at the intersection of some of the most consequential debates in modern AdTech, including cross-platform measurement, attention-based metrics, and privacy-compliant audience measurement in a post-cookie environment. She collaborates with a broad range of industry stakeholders to develop technical and operational standards that govern how impressions, viewability, and audience data are reported and verified. Lis represents the MRC's operational continuity and institutional knowledge, working alongside industry leadership to navigate the rapid evolution of measurement methodologies.
