Publicis Groupe and Microsoft are expanding their strategic partnership to build an AI-powered solution that they claim will not only “unlock creativity, accelerate innovation, and empower customers” but will also go beyond media to drive the next generation of business-wide AI.
The move, which sees the French agency group land Microsoft’s estimated $2bn global media account without a pitch, comes ten years after the two companies co-created the data-driven AI platform Marcel.
Now they plan to join forces to build a full-stack marketing solution that unifies legacy systems, AI agents and identity-based data to accelerate marketing outcomes in the era of agentic AI.
Unlike AI built on public data or siloed models, this partnership is anchored in Publicis’ data division Epsilon which fuses identity, media, marketing and customer intelligence.
It is claimed that AI agents built on Microsoft Fabric and powered by Epsilon will be able to reason, decide and act on trusted, real-world and proprietary data, to deliver impact that extends beyond model performance to sustained business value.
For example, an AI agent can autonomously identify high-value customer segments, generate and personalise content, deploy campaigns across channels, and continuously optimise spend in real time — within guardrails set by marketing leaders.
At a time when companies are moving faster than ever to adapt as customer behaviour shifts and increasingly need to connect their investments directly to revenue and outcomes, AI is being hailed as the technology that fundamentally changes the equation.
Through the partnership, Microsoft and Publicis plan to embed agentic AI across the entire flow of work so marketers can focus on what they do best: strategy, creativity and the pursuit of original ideas.
Publicis is putting Microsoft 365 Copilot in the hands of all 114,000-plus employees worldwide, as part of plans to strengthen its ability to deliver personalisation at scale and expand Marcel’s role from pioneering AI in marketing to powering the next generation of business-wide AI.
Publicis Groupe chief executive Arthur Sadoun (pictured) said: “Ten years ago with Microsoft we co-created Marcel, marketing’s first AI platform. Now we’re partnering again to shape the industry, this time as our clients confront the dynamics of the agentic era.
“Together, we are combining Microsoft’s unmatched technology and AI capabilities with Publicis Sapient’s transformation expertise on top of Epsilon’s industry-leading identity data to deliver agentic solutions that are truly game-changing for clients.
“Both our companies believe that the future of AI requires agents in service of people and humanity, and with this partnership we are creating a unique opportunity for our clients to lead against this ambition.”
Microsoft commercial business chief executive Judson Althoff added: “This partnership reflects our belief that AI must do more to serve humanity by empowering creativity and innovation. By bringing Microsoft’s cloud and AI capabilities together with Publicis Groupe Solutions built on Azure, we are giving creatives and makers the freedom to spend less time on repetitive execution and more time shaping ideas, building brands and driving meaningful growth for our customers.”
