Damien Geradin

Damien Geradin is one of the most influential legal voices in AdTech antitrust, widely recognized for his rigorous academic work and active litigation practice targeting anti-competitive conduct in digital advertising markets. His research on Google's dominance across the advertising technology stack — spanning ad servers, ad exchanges, and demand-side platforms — has been extensively cited by regulators, journalists, and policymakers on both sides of the Atlantic. He has played a direct role in shaping the regulatory and enforcement agenda around AdTech competition, including proceedings before the European Commission and in the United States. Geradin is a Founding Partner of Geradin Partners, a competition law boutique, and holds academic appointments that have allowed him to publish influential papers on market structure in programmatic advertising. He represents publishers, advertisers, and competitors challenging the conduct of dominant AdTech platforms, giving his academic work an unusually direct connection to live enforcement matters. His dual role as practitioner and scholar has made him a uniquely credible and prolific commentator on the intersection of competition law and digital advertising. Over a career spanning more than two decades in EU and international competition law, Geradin has built expertise in regulated industries, digital markets, and platform economics. He has testified before legislative bodies, contributed to policy consultations, and authored papers that have become standard references in AdTech antitrust discourse. His work on Google's alleged self-preferencing and conflicts of interest in the ad tech stack has been particularly impactful in framing how enforcers conceptualize structural remedies in the sector.
