This week marks the end of John Giannandrea's advisory role at Apple, concluding his tenure that began in 2018 after his time at Google. His departure coincides with the company's stock award vesting date on April 15, a practice known as “resting and vesting.” Giannandrea will pursue opportunities on company boards and advisory roles in the startup sector.
In December, Apple disclosed Giannandrea's transition from his primary position, where he was responsible for machine learning and AI strategy. Following the announcement, the company's AI structure underwent significant changes, including the appointment of Amar Subramanya as VP of AI, who now reports to Craig Federighi.
Giannandrea lost oversight of the Siri team in March 2025 due to a reported decrease in confidence from Tim Cook. The Siri division is now under the leadership of Mike Rockwell, while other responsibilities have been redistributed among Federighi, Eddy Cue, and Sabih Khan. Major new features for AI and Siri are expected to be unveiled at the upcoming WWDC, tied to the launch of iOS 27.
