Stagwell Media

Stagwell Inc.'s unified global media agency, competing with the media networks of major holding companies across 50+ markets with an AI-platform differentiator

Stagwell Media is the global media agency of Stagwell Inc., launched on 6 October 2026 when the holding company sunset its Assembly brand and relaunched it under the Stagwell Media name. The agency plans and buys media and delivers performance marketing services for major brands including Lenovo, Mastercard, and P&G across more than 50 markets worldwide. The rebranding consolidated Stagwell's media buying capabilities under a single, unified identity more closely aligned with the parent group. At the core of Stagwell Media's offering is Machine OS, Stagwell's proprietary AI-powered marketing platform, which underpins campaign planning, activation, and optimisation across channels. By integrating this technology layer into its media agency operations, Stagwell Media positions itself as a data-driven, AI-enabled alternative to the media agency networks operated by the traditional holding companies such as WPP, Publicis, IPG, and Omnicom. Operating across more than 50 markets, Stagwell Media competes for global media mandates from large enterprise advertisers seeking integrated media planning, buying, and performance marketing under one roof. Its launch reflects a broader industry trend of holding companies consolidating agency brands to reduce complexity and present more coherent, technology-forward propositions to clients.
