Horizon Media & Intent IQ Tackle the ID-less Advertising Puzzle

NEW YORK, NY – February 06, 2026 – In a significant move to address the advertising industry's most pressing challenge, Horizon Media has integrated Intent IQ's identity resolution technology into its newly launched marketing platform, HorizonOS. The partnership aims to give marketers a powerful new toolkit for reaching and measuring audiences in the rapidly expanding 'ID-less' digital landscape, which includes environments like Apple's iOS, Connected TV (CTV), and cookieless browsers such as Safari and Firefox.

This collaboration is not just a technical integration but a strategic response to the fragmentation of digital identity. As third-party cookies are phased out and privacy regulations tighten, advertisers have struggled to maintain campaign performance and scale. The alliance between Horizon Media, the largest independent media agency in the U.S., and identity technology leader Intent IQ signals a concerted effort to build a viable, privacy-first future for digital marketing.

The New Frontier of Digital Identity

The digital advertising ecosystem is in the midst of a seismic shift. For years, the third-party cookie was the linchpin of audience targeting, retargeting, and measurement. Its deprecation, coupled with Apple’s App Tracking Transparency (ATT) framework that requires user opt-in for tracking on iOS, has rendered a vast portion of the digital world opaque to traditional methods. These so-called ID-less environments now represent more than 50% of all digital touchpoints for U.S. users, creating a critical blind spot for marketers.

This challenge is particularly acute in high-value channels. CTV, for instance, operates in a largely cookieless environment, making it difficult to connect ad viewership to consumer actions on other devices. Similarly, users on Safari, Firefox, and soon Chrome, are becoming increasingly unaddressable through legacy tracking. This has left advertisers scrambling for solutions that can bridge the identity gap without compromising user privacy, a void this new partnership seeks to fill.

Horizon's Open Ecosystem Strategy

At the heart of this initiative is HorizonOS, which the agency bills as the industry’s first open and interoperable marketing operating system. Rather than building a closed, proprietary system—a common strategy among large agency holding companies—Horizon Media is fostering an ecosystem of best-in-class technology partners. This approach is designed to provide clients with greater flexibility, transparency, and access to cutting-edge innovation.

HorizonOS is built on what the company calls an "intelligence triad": the Blu platform for data-driven insights and activation, a suite of AI tools for automation and analysis, and the continued emphasis on human expertise and strategic oversight. By integrating partners like Intent IQ directly into this framework, Horizon aims to create a unified workflow for planning, activation, and measurement that functions seamlessly across all digital environments, including those without identifiers.

“Intent IQ represents the type of partner we look to bring into the HorizonOS ecosystem—a market leading company whose innovative technology is helping to drive real performance across today’s fragmented media landscape,” said John Koenigsberg, EVP & Head of Product Partnerships at Horizon Media. “Their identity technology will help us to extend reach and improve outcomes, especially across ID-less environments and supports our goal of building solutions that deliver flexibility, scale, and growth for our clients.”

Unlocking Reach with Privacy-First Technology

Intent IQ's technology provides the crucial link for HorizonOS to navigate the ID-less web. Backed by an extensive patent portfolio from its parent company, AlmondNet Group, Intent IQ has developed a next-generation identity graph that resolves user identity across devices and platforms without relying on traditional cookies or mobile ad IDs (MAIDs). It leverages a proprietary blend of deterministic and probabilistic signals in a privacy-compliant manner to connect user touchpoints.

Through this integration, HorizonOS gains a suite of powerful capabilities, including:

• Audience Amplification: Marketers can now extend their prospecting campaigns to find new customers on iOS mobile web, in-app environments, CTV, and cookieless desktop browsers, effectively doubling their potential reach.
• ID-less Retargeting: The technology enables re-engagement campaigns in environments where it was previously impossible. A user who browses a product on a Safari browser can be reached again on a different device, all without cookies.
• Performance CTV: It closes the loop between television and digital action. Advertisers can retarget viewers exposed to a CTV ad on their mobile phones or laptops, driving them down the purchase funnel and making CTV a more measurable performance channel.

“HorizonOS pioneers an open media ecosystem, giving marketers de-risked access to best-of-breed media infrastructure that drives immediate and lasting results,” stated Fabrice Beer-Gabel, Senior Vice President of Strategy & Partnerships at Intent IQ. “With this partnership we’re empowering marketers to activate ID-less audiences as a core part of their media strategies, with the potential to double reach while exceeding performance goals”.

The Untapped Value of ID-less Audiences

The ability to effectively target these previously unaddressable users unlocks significant economic advantages. According to Intent IQ, ID-less audiences are often associated with higher average household incomes and exist in less cluttered media environments, making them a highly desirable demographic for many brands. Because these audiences are harder to reach, the programmatic bidding dynamics can be less competitive, potentially leading to lower CPM clearing prices for advertisers who possess the technology to access them.

By accurately identifying and reaching these users, marketers can reduce wasted ad spend and deliver more relevant messaging, driving stronger performance across the entire marketing funnel. The partnership promises tangible improvements in key metrics, including higher conversion rates, lower cost-per-lead (CPL), and ultimately, a better return on ad spend (ROAS). This transforms the challenge of ID-less environments into a strategic opportunity for growth and efficiency.

This focus on performance in a privacy-first context positions the HorizonOS and Intent IQ solution as a compelling alternative to other industry initiatives. While universal IDs and Google's Privacy Sandbox offer partial solutions, this integration provides a comprehensive framework that works today across the full spectrum of ID-constrained channels. It suggests a future where effective advertising is not dependent on a single identifier but on a sophisticated, multi-faceted understanding of digital identity.
