Publicis and Microsoft Partner on Agentic Marketing Platform
On April 8, 2026 Microsoft and Publicis Groupe expanded a strategic partnership to build a full-stack 'agentic' marketing platform combining Microsoft Azure, Microsoft 365 Copilot and Copilot-agent tooling with Publicis’ Epsilon identity data layer and Publicis Sapient consultancy services. Publicis will roll out Microsoft 365 Copilot to more than 114,000 employees and named Azure its preferred cloud; Microsoft awarded Publicis the global media agency of record account previously held by Dentsu (reported at $1.2 billion). The platform architecture pairs Sapient’s Slingshot migration framework, an AI agent layer (Copilot Studio, Microsoft Agent 365, Microsoft IQ integrated via Sapient’s Bodhi) and Epsilon’s identity data to enable autonomous audience segmentation, content generation, campaign deployment and spend optimisation under human guardrails. The deal concentrates vendor dependence on Microsoft while Publicis bets its defensibility on Epsilon’s identity assets and Sapient’s transformation capabilities.
Microsoft Shifts Ad Strategy: AI Takes Center Stage
Microsoft may shut down its Xandr DSP early next year, signaling a strategic pivot in its adtech approach. In this AdExchanger Talks episode, Paul Longo, GM of AI in Ads at Microsoft Advertising, explains that sunsetting Xandr represents an evolution from a human-driven internet toward an agent-assisted, and eventually agentic, internet where agents can converse to complete tasks. Microsoft aims to invest in AI-powered elements across its ad tech and rely on the Microsoft Advertising platform as the buying platform to realize this vision. Longo emphasizes that AI is an enabler, not a replacement for people, citing a Microsoft survey that found 80% of respondents report not having enough time or energy for their current workload. In the near term, AI is expected to bring relief to media buyers. The episode also discusses conversational advertising experiences, Microsoft Copilot, and the difference between an AI assistant and an AI companion.
