WPP has acquired InfoSum, the world’s leading data collaboration platform, in a move to enhance its AI-powered marketing capabilities. The acquisition will integrate InfoSum into GroupM, WPP’s media investment arm, paving the way for the next generation of secure, AI-driven marketing solutions built on the industry’s most advanced data infrastructure.
This strategic move gives WPP and its clients immediate access to the largest privacy-safe, cross-platform dataset available today—revolutionizing marketing intelligence, audience targeting, and AI model development. By combining InfoSum’s patented cross-cloud collaboration technology with WPP Open, WPP’s intelligent marketing operating system, clients will be able to connect disparate data sources without moving or exposing sensitive information.
“Bringing InfoSum into WPP is a major step forward for our data capabilities and the results we can deliver for our clients,” said Mark Read, CEO of WPP. “It allows clients to stay in complete control of their first-party data, while accessing vastly greater quantities of high-quality, privacy-compliant data.”
Brian Lesser, CEO of GroupM, emphasized the transformational potential: “This is about more than just identity. It’s about building intelligence beyond identity—leveraging all the available data to train AI models at scale. Every new campaign will benefit from exponential network effects as our solutions learn and evolve.”
Lauren Wetzel, CEO of InfoSum, will remain at the helm of the company and also assume the role of Chief Solutions Officer at GroupM. “As privacy and security become non-negotiables, and AI reshapes marketing, our mission to power impactful, secure collaboration has never been more vital,” said Wetzel. “Joining WPP and GroupM enables us to accelerate this mission globally.”
InfoSum’s interoperable infrastructure ensures existing partners and clients can continue to collaborate securely while accessing next-gen AI solutions. The acquisition signals WPP’s commitment to delivering unparalleled data intelligence in the AI era, setting a new benchmark for marketing innovation.
