Microsoft and Publicis Groupe have expanded their decade-long partnership to develop a full-stack marketing platform built around agentic AI, integrating cloud infrastructure, identity-based data and AI agents across core business workflows to link marketing activity directly to revenue and measurable performance outcomes.

According to Edtech Innovation Hub, the agreement builds on planned components including migrating legacy systems to Microsoft Azure, embedding AI agents into business processes through Copilot Studio and Agent 365, and using Microsoft Fabric alongside Publicis' Epsilon data platform to support decision-making based on identity-level data.

The partnership represents a deliberate shift away from fragmented AI adoption toward connected systems where agents can operate across workflows, from campaign planning through to execution and optimisation. AI agents deployed under the agreement will be capable of identifying audience segments, generating and personalising content, deploying campaigns and optimising performance in real time within defined parameters.

As part of the arrangement, Publicis will roll out Microsoft 365 Copilot to more than 114,000 employees and deepen its use of Microsoft Azure as a preferred cloud platform. Publicis will also act as Microsoft's global media agency of record, extending the partnership beyond technology into media and performance.

For the broader digital transformation sector, the development underscores how enterprise AI is rapidly evolving from isolated tools into integrated, agent-based systems designed to drive operational outcomes at scale.

"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," said Arthur Sadoun, chief executive officer of Publicis Groupe.
