Future and InfoSum partner to scale privacy-first predictive audience targeting.

Future and InfoSum partner to scale privacy-first predictive audience targeting. 05/11/2026 Future, the global media company behind brands like Tom's Guide, TechRadar, PC Gamer, and Who What Wear, has partnered with InfoSum, a WPP company and the leading data collaboration platform, to provide advertiser and agency planners with privacy-first, real-time access to high-intent publisher audiences within their existing workflows. As part of the integration, Future's first-party audience capabilities will be available within Open Intelligence, WPP's shared intelligence layer inside WPP Open, giving WPP Media planners access to richer content consumption and intent signals to inform planning and activation for client campaigns. Future and InfoSum partner. The integration connects Future's industry-leading predictive audience intelligence engine, Aperture, with InfoSum's privacy-first infrastructure, enabling planners to access, analyse, and activate Future's audience segments in real time within existing environments. Planners can securely match client and Future first-party data to target existing and prospective customers, expand reach to new audiences with similar interests and intent, and apply those insights to broader campaign planning, including experiential and offline activations. Aperture uses Future's first-party behavioural signals across its portfolio of more than 170 media brands to build predictive intent segments. Its data science behind the platform uncovers both expected and unexpected audience intersections, revealing signals that traditional targeting may overlook. For example, a brief for a fashion retailer identified expected fashion and beauty audiences alongside less obvious, high-intent segments such as coupon seekers and tennis enthusiasts. Across recent retail, tech and fashion campaigns, Aperture has delivered double-digit increases in click-through rates, improved Return on Ad Spend (ROAS) and reduced Cost Per Acquisition (CPA). Through InfoSum's data collaboration infrastructure, advertisers can plan and activate media using high-intent consumer signals without moving, centralising, or exposing sensitive information, or compromising data security. The partnership supports Future's broader strategy to scale its first-party audience intelligence across major agency and advertiser workflows as demand grows for privacy-first, high-intent publisher data. By making Aperture accessible closer to the point of planning and activation, Future is reducing friction between publisher intelligence and media investment decisions. Mike Peralta, Global CRO at Future, said: "Agencies need seamless access to high-intent publisher data directly within the tools they use every day. By bringing Aperture into WPP Open Intelligence via InfoSum, Mediashotz is removing friction for planners and making it easier to leverage its rich, intent-driven audience intelligence at scale. "This partnership ensures advertisers can identify and activate high-performing predictive audiences across our portfolio of trusted, authoritative brands with maximum precision." Nick Henthorn, Global Head of InfoSum, Data and Technology Solutions, WPP said: Rich publisher intelligence becomes significantly more valuable when planners can access it where they already work, without requiring the underlying data to move or be centralised. "Partnering with Future enables us to make its actionable audience signals available directly within agency workflows while preserving data privacy and control. It's a powerful example of how decentralised data collaboration can make first-party intelligence more accessible and actionable at scale."

Eyeota partners with InfoSum to unlock privacy-safe B2B and B2C audience solutions for U.S. Advertisers.

Eyeota partners with InfoSum to unlock privacy-safe B2B and B2C audience solutions for U.S. Advertisers. Sep 22, 2026 2 Minutes Read The partnership makes Dun & Bradstreet and Eyeota B2B and B2C taxonomies, along with the D&B ID Graph, available to InfoSum clients to support activation, analytics, measurement, and offline data enrichment. NEW YORK (September 22, 2026) - Eyeota, a Dun & Bradstreet company and global provider of B2B and B2C audience solutions, today announced a partnership with InfoSum, a WPP company and the leading data collaboration platform. Dun & Bradstreet and Eyeota-owned-and-operated digital audience taxonomy, along with the D&B ID Graph, combined with InfoSum's privacy-safe data collaboration technology, enables advertisers to reach more precise B2B and B2C audiences, build smarter models, and measure performance without moving or exposing underlying data. Advertisers need data solutions that are both actionable and built for today's privacy requirements. As signal loss, data fragmentation, and regulatory scrutiny continue to reshape marketing, the ability to connect trusted audience and identity assets within secure collaboration environments has become a practical requirement for responsible audience strategy. This is particularly important in B2B marketing, where audiences move between professional and consumer contexts, making it difficult to build a connected understanding of their needs and behaviors. This partnership directly addresses that gap by making Dun & Bradstreet and Eyeota B2B and B2C data available through InfoSum for privacy-safe use across planning, activation and measurement workflows. "Marketers want to use data in ways that are both effective and responsible, but the industry has not always made that easy," said Marc Fanelli, SVP, Global Digital Audiences & Operations at Dun & Bradstreet. "They need to understand real audiences, reach the right customers, and prove what is working, while respecting clear boundaries around how data is handled. This partnership helps close that gap by making trusted audience and identity signals usable in a secure environment where privacy is built into the workflow from the start." By making Eyeota and Dun & Bradstreet's global audience and identity assets available through InfoSum's patented cross-cloud technology, advertisers can activate audiences across programmatic, social, and other channels in global markets. For marketers, the value is straightforward: they can bring audience planning, activation, and measurement closer together in a secure environment, without adding more complexity to how data is handled. "Data collaboration only works when every party in the ecosystem can trust the infrastructure it runs on," said Valerie Mercurio, Global Head of Data Enablement at WPP. "Eyeota and Dun & Bradstreet bring some of the most trusted audience and identity assets in the market. Making these assets available through InfoSum means advertisers can access that critical B2B and B2C intelligence in a way that is both effective and privacy-safe." With this partnership, advertisers gain a more connected and responsible path to B2B and B2C audience intelligence, one built for the realities of today's privacy landscape without sacrificing the performance outcomes that matter most.
