**John Giannandrea’s Exit from Apple: A Fresh Era in AI Leadership**
John Giannandrea, a key player in the technology sector, is officially wrapping up his time at Apple this week. After joining the firm in 2018 following an extensive eight-year spell at Google, Giannandrea took charge of Apple’s machine learning and artificial intelligence (AI) initiatives. His input was crucial in molding the company’s direction regarding AI technologies.
In December of last year, Apple disclosed that Giannandrea would be resigning from his leadership position but would remain an advisor until his complete exit in spring 2026. This transition is coordinated with Apple’s stock vesting timetable, enabling Giannandrea to take advantage of his stock awards prior to his exit.
Mark Gurman, in the latest edition of the *Power On* newsletter, revealed that Giannandrea’s advisory position wraps up this week, timed with Apple’s stock vesting date of April 15. After his exit, Giannandrea intends to participate with various company boards and offer advisory services within the startup landscape.
Giannandrea’s exit occurs amidst considerable shifts within Apple’s AI teams and organizational framework, especially after the debut of Apple Intelligence. Alongside Giannandrea’s departure, Apple appointed Amar Subramanya as the new Vice President of AI, reporting directly to Craig Federighi. Subramanya comes with extensive experience from his prior positions at Google and Microsoft.
Giannandrea’s supervision of the Siri team underwent notable changes in March 2025, as Tim Cook allegedly lost faith in his capacity to effectively drive product development. Currently, Siri’s leadership has shifted to Mike Rockwell, while Giannandrea’s additional duties have been reassigned to Craig Federighi, Eddy Cue, and Sabih Khan.
Looking forward, Apple is set to introduce major new AI and Siri functionalities as part of iOS 27 at the upcoming Worldwide Developers Conference (WWDC) in just two months. These functionalities will signify a new chapter for Siri, especially following Apple’s recent collaboration with Google to incorporate Gemini models into its AI offerings.
As Giannandrea steps into his next chapter, the tech community keenly observes how Apple’s AI strategy adapts under new leadership and what innovations will surface in the fields of machine learning and artificial intelligence.
