AI's Honeymoon With Advertisers Hits Reality Check
Adweek's Tech Advantage column examines how the advertising industry's initial enthusiasm for generative AI is colliding with real-world operational limits, including imperfect performance, limited controls, and unresolved accountability questions. The piece highlights Omnicom's recent decision to transfer more than 460 employees who built and operated its proprietary AI platform, Omni, to third-party contractor Endava. The holding company also cut some product and engineering positions. The move comes just months after Omnicom showcased a revamped version of the platform. The article suggests that as the industry scales AI deployments, companies are moving from experimentation toward managing the less glamorous side of AI, including infrastructure costs, staffing, and defining who is responsible when AI-driven systems fail.
Omnicom, one of the largest agency holding companies, moving 460+ AI platform staff to Endava signals a major shift away from proprietary in-house AI builds toward third-party contractors, highlighting the operational reality check facing AI adoption in advertising.

Agencies’ AI Operating Systems Face Commoditization Risk
Agencies have invested in proprietary AI-powered operating systems (WPP Open, Omnicom’s Omni, Stagwell’s The Machine, Havas Converged, PMG’s Alli, Horizon’s Blu, etc.) to centralize data, planning and creative tools and increase client stickiness. A Gartner research note warned that roughly half of agency-built AI platforms could fail by 2029, citing consolidation, advertisers building bespoke AI or buying from hyperscalers, and shrinking differentiation. Agency and holding-company leaders (e.g., Omnicom’s John Wren, WPP’s Stephan Pretorius) argue scale and negotiated enterprise agreements give them an advantage, while vendors such as Brandtech’s Pencil emphasize transparency about underlying models (Anthropic, OpenAI) and token-costing. The ANA survey flagged principal-media buying is widespread but governance lags. The briefing frames a growing industry debate over AI token economics, vendor transparency and whether hyperscalers will disintermediate agency platforms.
AI Can Build Ads, But It Can't Run Them
The article argues that generative AI has democratized ad creative—making high-quality assets fast and widely accessible—but that the primary performance risks now lie in execution: compliance, targeting precision, delivery, and optimization. AI-produced creative can still fail in-market if it doesn't account for platform policies, regulatory nuance (notably in healthcare, finance, and politics), or channel-specific constraints. The author contends optimization systems require human judgment to balance measurable outcomes with brand intent and compliance. The piece predicts a hybrid model where AI accelerates production and pattern-finding, while humans lead governance, campaign structure, and cross-channel execution. Fyllo is identified as a data and advertising partner focused on regulated industries.
BBDO NY CEO and CCO to Depart
Emma Armstrong, CEO of BBDO New York, and Michael Aimette, Chief Creative Officer, are departing the agency. This follows Omnicom's acquisition of IPG, which led BBDO to absorb creative rival FCB. Chief Client Officer Kelli MacDonald, another FCB alum, is also leaving for a new opportunity. The exits occur just 10 months after Omnicom closed its $13 billion acquisition of IPG, creating the largest agency holding company.
