Social Rocket
The international agency business is being reshuffled: Stagwell is bundling its media business under one brand, Havas is building international reach with Horizon, and Carat is positioning its planning more strongly around consulting and measurable impact. For brands, this creates a wider choice beyond the traditional large networks. What matters, however, is what technology, data access and accountability actually sit behind an agency presentation.
Stagwell turns scattered media units into one offering
On 6 October 2026 Stagwell introduced the new brand Stagwell Media. The previous assembly structure is thereby being converted into a joint international offering. According to the company, the new organisation is present in more than 50 markets.
The technical umbrella is called The Media Machine. Stagwell had already presented the system in June as a AI-powered media platform with more than 20 specialised agents. These are meant to support planning, optimisation and analysis, for example. For clients, what matters more is which tasks are automated and how results can be verified themselves.
We have already described the operational reorganisation in detail under Stagwell Media and the Media Machine. The bigger trend: numerous individual offerings are meant to become a service that is simple to buy.
Havas buys reach not only through acquisitions
Havas is taking a different route. The 2025 announced partnership with Horizon Media is meant to reach international clients through a shared network. Horizon Global was described at the announcement as having around 20 billion US dollars in media billings and a presence in 100 countries. The two partners remain independent companies.
Havas is growing in parallel through acquisitions. According to the results of 14 October 2026, net revenue rose by 7,2 percent in the third quarter, of which 2,4 percent organic. The group is also expanding its offering in Germany. Where the growth comes from is shown in our analysis of Havas's quarterly figures.
For international social campaigns, the mix can be interesting: one central point of contact, but specialised teams for local markets and channels.
Carat sells a difference, not just reach
At Dentsu, Carat places greater emphasis on the claim of distinguishing media planning from standardised booking processes. The agency explained its Difference Engineered concept in the October interview on the campaign. Behind this is the question of which media contacts actually contribute and how audiences can be reached beyond mere reach optimisation.
Especially in the paid social business, where platforms already automate numerous optimisation decisions, an agency must show its added value in data interpretation, creative strategy and experimentation. We examined the limits of fully automated buying using the example of Carat and Tinuiti.
Three questions for your next agency pitch
Anyone awarding media, creator or social mandates should not be swayed solely by network size and AI demos. Three pieces of evidence help with the selection: What raw data and measurement methods does the brand receive? Who approves changes to budget, targeting and creatives? And what concrete result does the agency contractually owe?
This also makes compensation negotiable. Our analysis of the WFA study on agency fees shows why defined services and output models are gaining ground over pure hourly billing.
The real competition among agency groups now takes place between working models: who can connect international campaigns, deliver local relevance and transparently demonstrate their value creation?
