Stagwell Merges Its Media Agencies Into a Single 'Stagwell Media' Network
Updated: 6 days ago
TL;DR: Stagwell has folded Assembly Global and ADK into a single global media network, Stagwell Media, spanning more than 50 markets and built around its AI-powered 'Machine OS', pitching itself as the agile alternative to the mega-holdcos.
What Stagwell Announced
Stagwell has consolidated its media capabilities into one global network, Stagwell Media, operating across more than 50 markets. Assembly Global — which spanned North America, Europe, MENA, India and APAC — is merged in, and ADK Global is incorporated to strengthen the APAC footprint, particularly Japan.
At the centre sits Machine OS, Stagwell's AI-powered 'agentic' marketing platform that connects clients' marketing systems, data and workflows. Named clients on the new network include Lenovo, Mastercard and P&G.
The Leadership and the Pitch
Liz Rutgersson, previously chief executive of Assembly Global, has been elevated to lead Stagwell Media as CEO, with Bridget Hopkins as CEO of Stagwell Media Europe and Slavi Samardzija as global chair of media and commerce.
Rutgersson framed the opportunity as a gap in the market: 'There's a perfect white space between that scale at absolute max and a newer, less dynamic agency.' The positioning leans on integrated solutions that combine global scale with specialist agility, stretching beyond media buying into customer experience and media-creative technology.
Marketing Minute's Read: Simplicity as a Sales Pitch
This is the defining agency story of 2026, playing out again. From WPP's restructure to the Omnicom-IPG combination, holding companies are consolidating brands, leading with an AI operating layer and selling simplicity. Stagwell's wager is that mid-scale plus agility plus a usable AI stack beats both the giants and the boutiques.
The risk is in the promise. 'One network, one OS' only wins if the operating system genuinely removes friction for clients rather than adding another logo to the deck. A platform is a promise until someone logs in and it actually saves them a day's work.
Quick FAQ
What is Stagwell Media?

Who leads it?
Liz Rutgersson, previously CEO of Assembly Global, leads Stagwell Media, with Bridget Hopkins as CEO for Europe and Slavi Samardzija as global chair of media and commerce.
Why consolidate now?

Every holding company is telling the same story right now: fewer brands, one AI operating layer, simpler buying. Stagwell's bet is that mid-size plus agility wins. It only works if the 'OS' actually removes friction for clients — a platform is a promise until someone logs in and it saves them a day. — Daniel Nikolla, Founder of Merx Marketing
'One network, one operating system' only wins if the OS removes real friction for clients — otherwise it's a rebrand with extra steps.
