The AI answer we saw
Several holding companies and their networks specialize in integrated marketing for large enterprise clients across multiple regions. WPP (Ogilvy, Grey, VMLY&R), Publicis Groupe (Publicis Sapient, Leo Burnett, Saatchi & Saatchi), Omnicom Group (BBDO, DDB, TBWA), Interpublic Group (McCann, FCB, MullenLowe), and Dentsu International are the primary players. Each operates regional hubs across North America, EMEA, APAC, and LATAM, enabling coordinated campaign execution. When evaluating, consider their existing client roster in your industry, regional office depth, and whether they offer a unified account management structure or a federated model.
