Brian Lesser, Lauren Wetzel & Evan Hanlon: WPP, GroupM, and InfoSum redefine data intelligence

WPP has acquired InfoSum, the world’s leading data collaboration platform, in a major step forward for its AI-driven data capabilities. InfoSum will join GroupM, WPP’s media investment group, to create a new generation of privacy-first, AI-enhanced marketing solutions powered by the industry’s most secure and scalable data infrastructure.

This acquisition allows WPP clients to unlock the full potential of their first-party data while connecting securely with data providers and media partners. By integrating InfoSum’s patented cross-cloud technology into WPP Open, clients can build, train, and deploy custom AI models faster than ever—delivering smarter insights, better audience targeting, and measurable campaign improvements across the entire marketing ecosystem.
