A New Chapter for European AdTech: Will Harmer Named Global CEO of Utiq

In a move signaling a transition from the "founding" phase to a period of aggressive scaling, Brussels-based advertising identity firm Utiq has officially transitioned its top leadership. On July 1, 2026, Will Harmer, who served as the company’s Chief Product Officer since its inception in 2023, assumed the role of Global CEO. He succeeds Marc Bresseel, the founding executive who was instrumental in transforming a joint-venture concept backed by Europe’s telecommunications giants into a functional, multi-market identity infrastructure.

The leadership change, formally disclosed by the company on June 9, 2026, marks a pivotal moment for one of the most closely watched infrastructure projects in the digital advertising sector. As the industry grapples with the permanent decline of third-party cookies and heightened regulatory scrutiny, Utiq—jointly owned by Deutsche Telekom AG, Orange SA, Telefonica S.A., and Vodafone Group plc—stands as a critical alternative for privacy-compliant audience identification.

The Evolution of Utiq: A Chronology of Growth

To understand the weight of this leadership change, one must look at the rapid maturation of the company under Bresseel’s three-year tenure. Utiq was launched in March 2023 with a singular mission: to leverage telecommunications network signals to create a consented, privacy-first advertising identifier that functions independently of browser-level tracking or device fingerprinting.

• March 2023: Utiq officially launches as a joint venture, entering the market with a focus on Germany, France, and Spain.
• January 2025: The company achieves a significant technical milestone by securing integration partnerships with eleven major supply-side platforms (SSPs), including industry heavyweights such as Magnite, Index Exchange, and PubMatic.
• June 2025: Utiq expands its operational footprint into the United Kingdom, bolstered by strategic partnerships with Virgin Media O2 and Vodafone.
• September 2025: A landmark partnership with Ad Alliance (RTL Deutschland) marks a major penetration into the German market, reaching 4 million users across premium properties.
• November 2025: Utiq hits a major performance benchmark, confirming 70 million consented users across six European markets.
• April 2026: Integration with Snack Media expands Utiq’s reach to an additional 110 million monthly users across a vast network of sports and entertainment properties.
• June 1, 2026: The company announces a high-profile integration with The Trade Desk, arguably its most significant demand-side platform (DSP) partnership to date.
• July 1, 2026: Will Harmer formally succeeds Marc Bresseel as Global CEO, marking the end of the foundational startup phase and the beginning of the "growth and adoption" phase.

The Architect of the New Era: Will Harmer’s Record

Will Harmer arrives in the CEO chair with a deep understanding of Utiq’s technical DNA. As the former Chief Product Officer, he was the primary architect of the company’s public positioning and technical strategy. His background—spanning roles at Vodafone Group, BT Group, and EE—provided him with the unique perspective necessary to bridge the gap between complex telecommunications infrastructure and the fast-paced requirements of the programmatic advertising ecosystem.

Throughout his time as CPO, Harmer emerged as a vocal advocate for Utiq’s "Authentic Audiences" model. He has been particularly outspoken regarding the competitive landscape, frequently criticizing Apple’s App Tracking Transparency (ATT) framework. Harmer famously described Apple’s approach not as a privacy victory, but as a "privilege" issue, arguing that the tech giant "weaponized privacy concerns to gain competitive advantage."

This combative yet calculated approach to regulatory and competitive discourse suggests that under Harmer, Utiq may lean further into its role as a disruptive force against the "walled gardens" of Big Tech. His recent work on the integration with The Trade Desk—which incorporates Germany’s netID framework—demonstrates his focus on interoperability. Harmer has characterized this strategy as a "belief that the future of identity must be open, trusted, and built around meaningful choice."

Supporting Data: The Power of Telco-Identity

The architecture Harmer inherits is structurally distinct from traditional adtech. Utiq relies on two core pillars: consenthub, a centralized portal for user privacy management, and consentpass, the mechanism for real-time signal matching between telcos, publishers, and advertisers.

The performance metrics released during Bresseel’s tenure underscore why shareholders remain committed to the model. In an Adobe-integrated pilot, Utiq demonstrated:

• 90% impression delivery: Success in non-Chrome browsers using the Utiq identifier.
• 290% uplift: A significant increase in deterministic reach compared to traditional cookie-based methods.
• 61% better re-identification: Enhanced accuracy in automotive sector campaigns conducted with GroupM.

These figures illustrate that the "telco-first" model is not merely a theoretical exercise in privacy but a viable commercial alternative to the status quo. With 70 million consented users and a growing publisher network, the foundation is set for the "next growth phase" that the board of shareholders identified in their transition statement.

Official Stance: A Planned Handover

The corporate messaging regarding the transition has been carefully curated to avoid any perception of instability. Utiq’s statement, released on June 9, emphasized that the decision was a collective agreement between Bresseel and the four parent telcos.

"Together, Marc and the shareholders have agreed that, with these foundations now firmly established, this is the right moment for a leadership transition," the statement read.

By framing the change as the completion of a "founding chapter," the company aims to reassure partners that the strategic roadmap remains unchanged. Notably, while Bresseel has stepped down as CEO, he remains listed as a "Director" on the company’s team page, suggesting a move toward a governance or advisory capacity. This continuity is vital for a joint venture, where the interests of four massive, independent telecommunications entities must be balanced.

Strategic Implications for the Identity Market

The transition of leadership at Utiq has profound implications for the broader European identity resolution market. As a joint venture, Utiq is not beholden to the traditional VC cycle, which often prioritizes rapid, potentially unsustainable growth. Instead, it operates with the backing of shareholders who have a long-term interest in maintaining the integrity of their network signals.

1. The Challenge of Scale

Harmer’s primary challenge will be moving beyond the "early adopter" phase. While 70 million users is a significant number, the challenge lies in achieving ubiquity. He must prove that Utiq’s signals can provide consistent, incremental value within the complex bidding environments of platforms like The Trade Desk.

2. Governance as a Competitive Advantage

Unlike conventional startups, Utiq’s governance structure is a testament to the influence of the telecom sector. Harmer will need to manage the expectations of four distinct corporate shareholders, each of whom has different strategic priorities within their home markets. His ability to maintain this coalition will be a key performance indicator.

3. The "Post-Cookie" Battlefield

The industry is currently in a state of flux as it waits to see how Chrome’s evolving privacy policies will impact the open web. Utiq’s positioning—being "privacy-first" by design—places it in a defensive and offensive posture simultaneously. Harmer’s history of criticizing Big Tech’s "double standards" suggests that Utiq will continue to lobby for a more equitable playing field, likely utilizing his deep regulatory and technical knowledge to advocate for policies that favor telco-based identity over walled-garden solutions.

4. Continuity vs. Innovation

The lack of a named successor for the Chief Product Officer role suggests that the leadership team may be undergoing a broader restructuring. Observers will be watching to see if Harmer maintains a hands-on approach to product development or if he delegates the technical roadmap to focus exclusively on the commercial and regulatory aspects of the CEO role.

Conclusion

As Utiq enters the second half of 2026, the transition from Marc Bresseel to Will Harmer represents the maturation of a bold, ambitious project. The company has successfully navigated the "zero-to-one" phase, building a robust, privacy-centric infrastructure that has the backing of Europe’s most powerful telecommunications providers.

For the advertising industry, the message is clear: Utiq is here to stay. Under Harmer’s leadership, the firm is expected to double down on its integrations with demand-side platforms and continue its expansion into new markets. While the departure of a founding CEO always brings uncertainty, the appointment of an internal successor who has already served as the face of the company’s product strategy provides a clear signal of continuity.

As the digital advertising ecosystem continues its shift toward consented, first-party-adjacent data, Utiq’s telco-powered model is no longer just a "promising alternative"—it is becoming a pillar of the European adtech stack. The next two years under Harmer will determine if that pillar can support the weight of the entire European market.
