Nadia Sonneveld

Nadia Sonneveld is recognized in the European AdTech ecosystem for her work at the intersection of data privacy law and programmatic advertising infrastructure. As Head of Privacy & Regulatory Affairs at Xandr, the demand-side and supply-side platform now operating under Microsoft Advertising, she leads the organization's compliance posture across GDPR enforcement, the IAB Europe Transparency and Consent Framework, and the emerging regulatory implications of the EU AI Act for ad targeting and algorithmic decision-making. Sonneveld's influence extends beyond internal compliance work through her active participation in industry standards bodies. Her representation of Microsoft at IAB Europe's TCF steering committees positions her as a key voice in shaping the consent and transparency frameworks that govern how hundreds of billions of programmatic ad impressions are transacted across Europe. This standards-setting role gives her outsized influence relative to a single-company role, as TCF policy decisions ripple across the entire European digital advertising supply chain. Her career trajectory reflects the growing importance of privacy-by-design thinking within AdTech platforms, moving from legal and regulatory advisory functions into operational leadership roles that require bridging technical ad infrastructure with evolving EU regulatory requirements. She is regarded as a practitioner who translates complex regulatory obligations into actionable product and operational frameworks for programmatic platforms.
