Microsoft CEO Satya Nadella has restructured the senior leadership team that ran Microsoft for decades, replacing it with leaner, startup-style teams built for the AI era. Business Insider reports the SLT is gone, swapped for a five-person corporate group, a 35-strong engineering team and a dedicated Copilot unit. Nadella now reviews AI metrics weekly. Longtime executives including Rajesh Jha, Yusuf Mehdi and Charlie Bell are out as Microsoft’s AI reboot reshapes its power structure.
