Microsoft confirmed Oct. 1 that Ryan Roslansky will leave the company by the end of 2026. He ran LinkedIn for six years and spent nearly 18 years at Microsoft overall1. Peter Lee, the 16-year veteran who led Microsoft Research and most recently ran Microsoft Science, departs the same week2. Both exits fit a pattern Satya Nadella has repeated through 2026. He keeps trading people who built Microsoft's last decade for people who arrived at the company within the past year or two. The clearest example already sits atop Copilot, the product every one of these departures ultimately serves. It shows what the chief executive is betting the trade buys him.
Copilot sits at the center of that bet for a simple reason. Microsoft has staked its AI story on it in every earnings call since 2023. The product now reaches inboxes, spreadsheets, code editors and the Windows taskbar. That reach means the person running it effectively runs Microsoft's answer to the entire AI moment. Nadella picked someone with a year of tenure for that job. The choice says as much about what he thinks the job requires as any memo could.
A 33-year-old now answers for Copilot
Jacob Andreou joined Microsoft from Snap a year before Nadella put him in charge of Copilot in March35. The job carries oversight of more than 11,000 employees. Only 4.5 percent of Microsoft's 450 million Microsoft 365 customers pay for Copilot features5. That conversion rate explains why Nadella reached past the company's own bench for a fix. Andreou frames the job as a sprint that keeps restarting. "Because the technology is moving so quickly, the reality is a six to twelve month roadmap doesn't really exist in the way it used to," he said3. He added that the moment demands constant motion: "This is one of the most intensely competitive environments tech has seen in the last 20 years"3. A roadmap that dissolves every six months rewards someone who built his career assuming motion. That is a fair description of a 33-year-old eleven months into the job. Khalid Karim, a longtime friend who partnered with Andreou at hackathons before either worked in tech, pointed to a specific kind of focus. "There's definitely a portion of his brain that's constantly engaged in thinking about technical problems," Karim said5. That read fits a company that wants an engineer's instinct applied to a sales and marketing problem, which is closer to what Copilot's low conversion rate actually is.

Wall Street still calls the product a problem
Jefferies analyst Brent Thill told Fortune that Microsoft carries "the best distribution in software and tech." He added a blunter verdict on how customers rate what Andreou inherited: "it stinks"3. Chad Morganlander, a senior portfolio manager, read the reorganization as a cure rather than a symptom. He credited it for "getting rid of multiple levels of bureaucracy and becoming more focused on the end product and the user"3. Both readings can be true in the same quarter. A product can carry weak reviews and a faster org chart at once. Microsoft is betting the second fixes the first before shareholders lose patience with either.
Sharma's promotion follows the same shape
Asha Sharma arrived from Instacart and Meta in February to replace Phil Spencer atop Microsoft Gaming. The swap left her résumé thin on games experience and thick on marketplace and consumer-product management instead4. She used her first message to staff to draw a line Andreou's own memos skip entirely: "we will not chase short-term efficiency or flood our ecosystem with soulless AI slop. Games are and always will be art, crafted by humans, and created with the most innovative technology provided by us," Sharma wrote4. The promise reads as a hedge against the very tool her new boss is racing to ship everywhere else at Microsoft. Gaming gets a guardrail in writing. Copilot, under Andreou, gets a deadline instead. Spencer had run Microsoft's gaming division for more than a decade. His tenure spanned the Activision Blizzard acquisition and the launch of Xbox Game Pass as a subscription business. Sharma inherited that portfolio roughly seven months into her time at Microsoft.
What leaves when Lee leaves
Lee spent 16 years at Microsoft and ran a research division of roughly 1,500 scientists at its peak2. He used that organization to push AI work in biology, medicine and the physical sciences. His own account of why he is going keeps every complaint about Microsoft out of the record entirely. "A once-in-a-lifetime opportunity to join an elite team, fulfilling a dream I've had since childhood," is how he described the move. He called it "a major detour from what I've been doing over the past 2+ decades"2. Taken at face value, a scientist chose adventure over tenure. Set beside the calendar, Lee is also the fourth senior leader this year to leave, after Spencer, Rajesh Jha and now Roslansky. Microsoft's chief executive keeps describing the moment as one demanding speed above all else. People positioned to judge that bet better than almost anyone keep opting to watch its outcome from somewhere else.
Jha's own exit traced a quieter version of the same arc. He spent more than 35 years at Microsoft, rising to run the Experiences and Devices group that covered Windows and Microsoft 3656. Retirement came July 1, and his responsibilities split among four newer executives at once. Lee's research organization and Jha's product empire each took decades to build the judgment each man eventually exercised. Microsoft is replacing both of them with people who have held their new jobs for months. The bet is that judgment built over decades costs more time than the market will lend the company.

What each side would need to be true
Nadella's case rests on urgency paying for itself. "With Copilot, we are executing rapidly against our vision to build a new OS for work that spans every model," he said of the Oct. 1 changes1. He credited Roslansky's near two decades for building "how people around the world find opportunity," even while moving that work to others. For Nadella's case to hold, Andreou's sprint has to convert Copilot's 4.5 percent into something that justifies the churn. Sharma's gaming guardrail also has to coexist with Andreou's software urgency rather than contradict it. Lee's quiet exit makes the opposite case in a tone that stays level throughout. The people who spent decades building Microsoft's research and talent bench are choosing somewhere else, on their own terms, rather than staying to learn if the bet pays off. Jha's retirement adds a third data point to Lee's two. Three veteran leaders chose an exit on their own schedule rather than a seat at the table for whatever Andreou and Sharma build next.
By the numbers
- 16 years: Peter Lee's tenure at Microsoft before his Oct. 1 departure, after running Microsoft Research2.
- Nearly 18 years: Ryan Roslansky's combined tenure at LinkedIn and Microsoft before his own Oct. 1 exit1.
- 33: Jacob Andreou's age when Nadella handed him Copilot in March, after one year at the company3.
- 11,000: employees who now report up through Andreou's organization3.
- 4.5 percent: the share of Microsoft's 450 million Microsoft 365 customers who pay for Copilot features5.
- Four: senior Microsoft leaders, Spencer, Jha, Lee and Roslansky, who left or were reassigned in 202626.
- 1,500: scientists who once reported through Lee's research organization at its peak2.
- 35-plus years: Rajesh Jha's tenure at Microsoft before retiring July 1 and splitting his portfolio among four executives6.
What to watch
Watch who Microsoft names to fill Roslansky's combined LinkedIn and Office portfolio, and whether that successor comes from inside the company or outside it, the same way Sharma and Andreou did. Copilot's paid conversion rate is the clearest scoreboard for Andreou's bet; a meaningful rise above 4.5 percent by Microsoft's next earnings call would support Nadella's case, and a flat line would support Lee's quiet exit as the smarter read. Whether Lee's "elite team" ever becomes public will also show whether institutional memory left Microsoft for a rival or for something the AI race has yet to name.
