What FCB/SIX does
FCB/SIX was a full-service marketing and technology consultancy agency headquartered in New York, founded in 2016 and operating with 101-250 employees. It was structured as a subsidiary brand of Interpublic Group until December 2, 2025, when Omnicom Group completed its $9 billion acquisition of Interpublic Group, making Omnicom the world's largest agency group by revenue with approximately 105,000 employees post-restructuring. As part of the integration, Omnicom announced a sweeping restructuring that includes axing the FCB brand (alongside DDB and MullenLowe) and consolidating operations into three global creative networks (BBDO, TBWA, McCann) organized around nine 'Connected Capabilities' spanning advertising, branding, commerce, experiential, health, media, precision marketing, production, and public relations.
At the holding-company level, the technology stack is anchored by the Omni AI-driven marketing intelligence platform, which is positioned to unify creativity, media, data, and AI across the consolidated agencies. Omni's documented architectural features include Central Orchestration (a unified cross-agency workflow), Personalized Production at Scale (AI-powered content creation), Predictive Intelligence (forecasting-driven decisioning), a Unified Intelligence Backbone (single source of truth), Outcome-Driven Activation (outcome-linked media buying), and Localized Optimization (global scale with local precision). No proprietary technology, patents, or AI capabilities are attributed to FCB/SIX as a standalone entity in the available source material, and FCB/SIX's own product or service portfolio is not separately documented.
The business model operates as professional services revenue generated through project-based and retainer arrangements with enterprise clients, executed via large-scale enterprise field sales teams and inside sales organizations serving the world's leading brands. Channel partnerships include first-mover media agreements with NBCUniversal (connected TV advertising) and Paramount+ (dynamic ad units in streaming premieres), both announced at Cannes Lions 2026. FCB/SIX's operating status is effectively closed as a distinct brand following the December 2025 restructuring announcement, with its client relationships and operations absorbed into Omnicom's consolidated creative network structure.
