Bob Lord Urges Agency Transparency and AI Reinvention
Bob Lord, president of Horizon Media Holdings, delivered a keynote at the Advertising Research Foundation’s Audience X Science conference arguing that traditional agency business models are antiquated and lack transparency. Lord said agencies must redesign around performance alignment, clear disclosure of platform and data fees, and explainability in AI models; Horizon discloses technology fees and charges a Blu fee for its AI platform. Forrester’s Jay Pattisall warned that emerging agentic media buying could increase opacity even as it reduces intermediary hops and fees. A separate report from Keen Decision Systems found 44% of advertisers plan to in-house more media planning, and that brands are testing advertising within generative-AI interfaces. The briefing also notes industry product and funding news: Dentsu launched a Global Media Planner (powered by Lumen), and new AI-native agency Multiply raised $9.5 million.
Agency business-model change and AI-driven transparency affect media-buying economics, fee structures, and client-agency relationships; agentic buying and in-housing trends could shift programmatic flows and intermediary fees.

Agency 'Black Box' Is Breaking, Says Horizon's Bob Lord
Bob Lord, president of Horizon Media and former CEO of Razorfish who led digital transformation at IBM, argues that many agencies are focused narrowly on cost-cutting with AI rather than using AI to drive advertiser growth. Lord says supply-chain opacity, siloed tech stacks and hidden programmatic costs persist, and that transparency, open-source approaches and performance-based compensation models can help agencies become true growth partners. At Horizon, Lord says the agency is shifting toward payment tied to client business outcomes and is pushing for transparent contracts that pass publisher discounts to clients. He calls for systems that let clients self-serve campaign insights and for tighter integration of creative and media to deliver measurable business impact.
CMOs Should Demand Control in the AI Era
An opinion piece published during Cannes Lions 2026 argues that chief marketing officers must insist on transparency, data ownership, and flexible operating models from agency partners as AI transforms marketing. The authors — Bob Lord (CEO) and Renata Spackova (COO) of Horizon Global — say many agency platforms have become opaque, lock clients into technology and profit models that misalign with brand needs, and resemble 'agency walled gardens.' They cite a 3C Ventures whitepaper, What Are You Buying?, which finds platform-language uniformity and weak governance drive marketer confusion. Horizon Global, a joint venture between Horizon Media and Havas Media Network launched in late 2025, promotes its BluConverged platform, single-P&L structure, and explicit client data ownership as solutions to these challenges. The article urges marketers to treat agency partners as growth builders who enable client control rather than gatekeepers.
Agencies Discuss Adapting to AI at Marketecture Live
At Marketecture Live in New York City, a panel led by Bob Lord (President, Horizon Media), Obele Brown-West (President, Colle McVoy) and Mike Shields (Founder, Next in Media) examined how advertising agencies must adapt to rapid AI adoption. Panelists said AI brings both confusion and opportunity, but legacy technology stacks and siloed systems are the main barriers to progress. They argued the future will be platform-based, not siloed, and that AI will scale execution rather than replace human creativity. The discussion stressed upskilling existing talent over wholesale replacement, evolving agency business models, rising legal and transparency concerns, and the reconvergence of creative and media capabilities.
