James Prudhomme

James Prudhomme is recognized across the AdTech industry for his work at the intersection of addressability, privacy, and data ethics — a rare combination that has made him a sought-after voice as the industry grapples with the deprecation of third-party cookies and evolving identity solutions. As SVP of Addressability & Data Ethics at Index Exchange, he leads the company's strategy around identity, helping publishers and buyers navigate a fragmented and rapidly changing landscape with both commercial pragmatism and ethical grounding. Prudhomme has built his career at the supply side of programmatic advertising, developing deep expertise in how identity signals, data clean rooms, and privacy-preserving technologies intersect with real-world monetization. His role at Index Exchange places him at the center of industry-wide conversations about sustainable, consent-based advertising infrastructure, and he has been active in contributing to standards and frameworks that extend beyond any single company's interests. He is known for translating complex technical and regulatory concepts — from universal IDs to contextual targeting to seller-defined audiences — into actionable strategies for publishers and the broader ecosystem. His dual focus on commercial addressability and ethical data use reflects a growing industry consensus that long-term viability in AdTech requires both.
