Microsoft's Copilot overhaul

Copilot is Microsoft's big bet on AI across apps like Word and Excel, but things got messy with separate teams working in silos.
This restructure aims to bring everyone together for a clearer direction and better user experience.
Nadella's plan centers on four pillars: how Copilot feels, its platform, integration with Microsoft 365 apps, and smarter AI models.

Andreou's new role and his experience

Andreou joined Microsoft last year from Snap and now takes charge of Copilot's design, product, growth, and engineering across both consumer and business sides.
He'll also work closely with Suleyman as they push to make Copilot more useful: think your go-to digital sidekick in everyday tasks.

Suleyman's shift in focus

After leading consumer Copilot, Suleyman will now focus on building enterprise-ready AI models that power products across the company—a key part of Microsoft's plan to weave AI into everything it does.
