In yesterday’s earnings call, Microsoft shared that Microsoft 365 Copilot has surpassed 30 million paid seats, with net seat adds more than doubling quarter over quarter. This milestone signals a broader shift as AI moves from assistant to active participant, with organizations redesigning workflows and employees directing agents to take on tasks. New data from Microsoft 365 Copilot telemetry signals, along with customer and internal examples, demonstrate this transformation in three ways: how deeply people use AI, what AI makes possible, and how organizations tailor it to specific roles. A new kind of AI product has emerged: a model wrapped in an agentic harness that can close its own feedback loop. This approach enabled Copilot Cowork, which became generally available in June, taking on multi-step work and returning completed results. Testing showed Cowork was 30% to 40% cheaper compared to a single model option. Microsoft also introduced its first autopilot agent, Microsoft Scout, which stays active in the background with its own identity and permissions. The core Cowork team grew from three engineers at the start to just nine when the product became generally available, with remarkable speed-to-market from inception to preview to use.
