Stagwell Media Launches as Global Media Agency
Stagwell, the challenger agency network, has launched a new global media agency, Stagwell Media, which will be built on the foundation of its existing performance marketing agency Assembly. The new agency will be led by Liz Rutgersson, who recently joined as Assembly's CEO. Rutgersson emphasized that Stagwell Media is not an umbrella brand and that other Stagwell agencies like Crispin and Gale will continue to operate independently. The launch comes as competitors like WPP have consolidated their media offerings into umbrella brands. Rutgersson stated the new agency aims to fill a gap between traditional, complex agency models and fragmented specialist providers, with a strong focus on agentic AI and speaking to machines, not just human audiences. The announcement was made during Advertising Week New York.
Stagwell Media launch signals a shift in agency models, emphasizing differentiation and AI-driven future, potentially influencing how media agencies structure themselves and compete.

Liz Rutgersson Named CEO of Stagwell's Assembly
Stagwell-owned agency Assembly has appointed Liz Rutgersson as its new CEO, with a global and North American remit.

Stagwell launches Curate inventory marketplace
Stagwell has launched Stagwell Curate, an inventory marketplace aimed at giving the agency holding company more control over where client media dollars flow. Matt Adams, global CEO of Stagwell Media Platform, told Digiday the offering is not intended to replace existing ad tech like DSPs but to improve execution within programmatic inventory. The article frames the move as part of a broader tug-of-war: DSPs, SSPs and agency holdcos are all vying to replicate parts of the programmatic supply chain, with consolidation in the middle layer expected as AI and new technologies reshape how inventory is curated and sold.
Stagwell launches AI media curation marketplace
Stagwell is building and set to launch 'Stagwell Curate', an AI-driven media curation platform that aggregates curated CTV, online video, display and audio inventory from publishers and adtech partners into a central reservoir. The system uses AI agents (built with Claude) and data from The Trade Desk’s OpenSincera to perform a "domain health check" that evaluates ad- and supply-chain quality and web technical performance, then assembles bespoke inventory packages for clients. Stagwell says the platform aims to reduce reliance on third‑party DSP/SSP marketplace tooling, lower tech fees, increase transparency and speed for media buyers, while still using DSPs to execute bids. The effort leverages publisher relationships with Magnite and Freewheel and follows other agency and holding-company moves to bring curation upstream.
