S4 Capital vs SAMY

Agencies Rethink Ownership of Agentic AI and Data

At Programmatic IO in New York, agency leaders debated the future of data and AI tool ownership. Executives from S4 Capital, Horizon Media, Dentsu, and WPP agreed that agencies should avoid owning client data and AI models to maintain neutrality and avoid conflicts of interest. They highlighted a shift from FTE-based compensation to outcome-based pricing and licensing AI tools to clients. The panel also discussed AI's impact on DSPs, with WPP's McAndrew noting a move toward agent-to-agent interactions and increased supply-chain compression. Sorrell warned of Big Tech platforms like Meta becoming end-to-end threats, pushing agencies to become validators. The discussion reflects a broader industry trend away from data ownership, contrasting with Publicis's acquisition of LiveRamp.
