Microsoft is launching its Microsoft 365 Copilot AI assistant to all of Accenture's approximately 743,000 employees, marking the largest enterprise Copilot deployment so far. The move comes as Microsoft's shares have dropped 12% this year due to concerns about the company's AI adoption and growth. The launch of Copilot is significant for Microsoft as only around 3% of its 450 million-plus Microsoft 365 enterprise users currently pay the $30 per month Copilot premium. The success of the Accenture deal is also seen as a blueprint for other large customers considering similar deployments. The commercial success of this rollout also includes the development of Avanade’s D3 platform, a sales intelligence tool developed by Accenture and Microsoft, which uses Copilot to aggregate internal data, industry context, and external sources into a real-time briefing for sales representatives.
