Dave Brown Leaves Amazon, Dave Treadwell Takes Over AWS Leadership Position
Dave Brown is leaving Amazon after 19 years, with Dave Treadwell set to lead AWS. Brown's departure and Treadwell's appointment were announced on July 15, 2026. Treadwell takes over the leadership role at Amazon Web Services.
AMZN is undergoing a leadership change atop its cloud division. Dave Brown, who spent nearly 19 years at the company and most recently led AWS's Compute and Machine Learning Services group, is departing. Dave Treadwell, an Amazon veteran who has run the company's eCommerce Foundation since joining in 2016 after 27 years at Microsoft, has been named to take over Brown's responsibilities.
The reshuffle touches one of AWS's most consequential leadership seats, since Compute and Machine Learning Services oversees EC2 along with the Bedrock and SageMaker platforms central to Amazon's AI infrastructure push. Brown is expected to remain with the company through the transition period before moving to a new role outside Amazon. Shares of Amazon rallied more than 3% as investors weighed the announcement, though the move likely reflects broader market sentiment as much as the specific personnel change.
For AWS, the succession could be read either as a routine executive transition after nearly two decades of institutional knowledge concentrated in one leader, or as a moment of some uncertainty as a new executive steps into a technically demanding role. How smoothly Treadwell absorbs those responsibilities, and whether AWS's cloud and AI momentum continues uninterrupted, could shape investor perception of Amazon's cloud leadership bench over the coming quarters.
