Microsoft and Publicis Groupe have announced an expansion of their long-standing strategic partnership to build a full-stack, AI-powered marketing solution aimed at helping businesses navigate the emerging era of “agentic” artificial intelligence.
The announcement, made on April 8 from Redmond and Paris, comes a decade after the two companies co-developed Marcel, one of the advertising industry’s earliest AI platforms. The renewed collaboration seeks to integrate AI agents, identity-driven data, and cloud infrastructure to deliver more connected and measurable marketing outcomes.
As brands face rapidly evolving consumer behavior and increasing pressure to tie marketing investments directly to business performance, the partnership aims to embed AI across workflows—allowing marketers to shift focus from execution to strategy and creativity.
“Ten years ago with Microsoft we co-created Marcel, marketing’s first AI platform,” said Arthur Sadoun, CEO of Publicis Groupe. “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.”
The companies said the collaboration will address fragmentation in current AI offerings by delivering a more unified transformation model. This includes migrating legacy systems to the cloud through Publicis Sapient’s Slingshot framework, built on Microsoft Azure, to establish scalable foundations for AI adoption.
The partnership will also integrate Microsoft’s AI tools—including Copilot Studio, Agent 365 and Microsoft IQ—into Sapient’s platforms, enabling enterprises to deploy and scale AI agents across marketing, commerce and customer engagement functions. Publicis’ Bodhi platform will support enterprise-grade deployment, linking data, workflows and decision-making.
A key component of the offering is an identity-based data model powered by Epsilon, Publicis Groupe’s data platform. By combining proprietary identity data with Microsoft Fabric, the companies aim to enable AI systems that can autonomously identify audience segments, personalize content, execute campaigns and optimize performance in real time.
“This partnership reflects our belief that AI must do more to serve humanity by empowering creativity and innovation,” said Judson Althoff, CEO of Microsoft’s commercial business. “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.”
As part of the agreement, Publicis Groupe will roll out Microsoft 365 Copilot to its more than 114,000 employees globally and has selected Azure as a preferred cloud platform. The move is expected to enhance personalization capabilities at scale and expand the role of Marcel from a standalone AI tool to a broader enterprise-wide system.
In addition, Publicis Groupe has been named Microsoft’s global media agency of record. The companies said this will enable deeper collaboration in linking audience insights, signals and performance data to improve marketing effectiveness and business outcomes.
