John Giannandrea is a Scottish-born software engineer and technology executive who ran artificial intelligence organizations at two of the largest consumer technology companies in the world. He led Google's combined search and AI group between 2016 and 2018, then spent eight years at Apple as senior vice president for Machine Learning and AI Strategy, the executive ultimately responsible for Siri, Core ML, and the model work underneath Apple Intelligence.[1][2]

Before either job he was a startup founder twice over. He was part of the founding team at the voice services company Tellme Networks, and he co-founded Metaweb, whose Freebase database of structured facts became one of the inputs to Google's Knowledge Graph after Google bought the company in 2010.[4][5][9][10][11]

His Apple tenure ended in a public unwinding of the job he had been hired to do. Apple moved Siri out of his organization in March 2025 after the personalized assistant demonstrated at WWDC 2024 slipped by roughly a year, and moved the robotics group away a month later.[18][20] On December 1, 2025 Apple announced that he was stepping down and would retire in spring 2026; he left in April 2026, and what remained of his organization was divided among Craig Federighi, Eddy Cue, and Sabih Khan.[1][26] Later that month he was reported to be taking a part-time advisory role at Cusp AI, a materials discovery startup in Cambridge, England.[27][28]

Early life and education

Giannandrea was born in Bridge of Allan, a town near Stirling in Scotland. An October 2015 Fortune profile gave his age as 50, which places his birth in 1964 or 1965.[4][5] He studied at the University of Strathclyde in Glasgow, where he took a Bachelor of Science with honours in computer science.[6]

Early career

Giannandrea worked as a senior engineer in the 1990s at General Magic, the Apple spinout that built handheld communicators and early software agent technology.[4] Fortune, profiling him in 2015, called the early personal assistant he worked on there his first attempt at humanizing machines.[5] He then moved to Netscape, where he worked as chief technologist of the web browser group.[4]

In 1999 he joined the founding team of Tellme Networks, a company built by Mike McCue and Angus Davis around telephone speech recognition and the VoiceXML standard; Giannandrea served as its chief technology officer.[4][7] Tellme ran a free voice portal reachable at 1-800-555-TELL that answered spoken requests for directory listings, weather, sports scores, and driving directions, and it later sold the same technology to enterprises as a customer service platform. Microsoft announced an agreement to buy the company on March 14, 2007, saying it expected to close in the second quarter and declining to disclose financial terms; Steve Ballmer framed the deal around speech as "a key interface for computing."[8] The purchase price was widely reported afterwards at roughly $800 million.[7]

Metaweb and Freebase

Giannandrea co-founded Metaweb in July 2005 with Danny Hillis and Veda Hlubinka-Cook.[9] The company's product was Freebase, a collaboratively edited database of entities and the relationships between them: films, books, people, companies, places. Where a search engine of the period indexed strings of text, Freebase was an attempt at machine-readable knowledge representation covering the same subject matter.

Google announced its acquisition of Metaweb on July 16, 2010, for an undisclosed sum.[9][10] Freebase went on to power the Knowledge Graph in part, the entity panels Google began showing beside search results after a May 2012 announcement.[11] Google retired Freebase in 2016 and migrated the portions that met notability requirements to Wikidata.[9][11]

Google, 2010 to 2018

Giannandrea arrived at Google through the Metaweb deal and stayed eight years. He worked on the Knowledge Graph and on applying machine learning across Google products, including RankBrain, which incorporated machine learning techniques into search results.[12][15]

In February 2016 Amit Singhal, the senior vice president in charge of Google's search products and its 176th employee when he joined in 2000, announced that his last day would be February 26, and Google said Giannandrea would replace him.[12] Time read the handover as a measure of how central artificial intelligence had become to the company's plans for search, pointing to Giannandrea's work on RankBrain.[12] He ran the combined search and AI organizations until 2018.[14]

He also became one of Google's more visible public voices on the limits of the technology. At a company conference on human-AI interaction in October 2017 he argued that the field's real hazard was algorithmic bias rather than machine superintelligence: "The real safety question, if you want to call it that, is that if we give these systems biased data, they will be biased." He pressed for disclosure of training data and warned against opaque systems in high-stakes settings, saying that "if someone is trying to sell you a black box system for medical decision support, and you don't know how it works or what data was used to train it, then I wouldn't trust it." On existential risk he was blunt: "What I object to is this assumption that we will leap to some kind of super-intelligent system that will then make humans obsolete. ... I just see no technological basis as to why this is imminent at all."[13]

When he left in April 2018, Google split the combined job back into two. Ben Gomes, who had run search engineering, took over all of search, and Jeff Dean added Google's AI organization to his existing leadership of Google Brain.[14]

Apple, 2018 to 2026

Hiring and remit

Apple confirmed the hire on April 3, 2018. Tim Cook announced it in an email to employees that stressed the company's positioning rather than the technology: "Our technology must be infused with the values we all hold dear. John shares our commitment to privacy and our thoughtful approach as we make computers even smarter and more personal." Giannandrea reported directly to Cook.[15]

On December 20, 2018 Apple named him to its executive team as senior vice president of Machine Learning and Artificial Intelligence Strategy. Apple's announcement put strategy for AI and machine learning across all products and services in his remit, along with the development of Core ML and Siri technologies.[2]

The organization he built out was research-heavy and largely invisible to customers. In a 2020 interview with Ars Technica he described machine learning as having become ambient inside Apple's operating systems rather than a discrete feature: "There are increasingly fewer and fewer places in iOS where we're not using machine learning," he said, adding that "it's hard to find a part of the experience where you're not doing some predictive work." He tied that to running models locally on Apple silicon and the Apple Neural Engine, and said the goal was for the intelligence itself to disappear from view.[16] By the time he stepped down, Apple described his teams as responsible for Apple Foundation Models, Search and Knowledge, Machine Learning Research, and AI Infrastructure.[1]

Apple Intelligence and the Siri delay

Apple announced Apple Intelligence on June 10, 2024 for iOS 18, iPadOS 18, and macOS Sequoia, pairing on-device generative models with Private Cloud Compute, a server tier running on Apple silicon that the company said would not retain user data and could be inspected by outside researchers.[17] The demonstration included a rebuilt Siri with onscreen awareness, personal context drawn from a user's own device data, and the ability to chain actions across apps.[17]

Those specific Siri capabilities did not ship on schedule. In March 2025 Apple said the smarter version of Siri was not ready and announced a delay of about a year, and the slip became the defining event of Giannandrea's Apple tenure.[18][25]

The consequences arrived in stages:

DateChangeSource of report
March 20, 2025Siri moved to Mike Rockwell, who had led the Apple Vision Pro group, reporting to software chief Craig Federighi; Paul Meade took over the Vision Products GroupBloomberg[18][19]
April 24, 2025Apple's robotics team, led by Kevin Lynch, moved to hardware engineering head John TernusBloomberg[20]
July 7, 2025Ruoming Pang, who ran the team that trained the foundation models behind Apple Intelligence, left for MetaBloomberg[22]
October 10, 2025Apple reported to be searching for a replacement for GiannandreaBloomberg[23]
December 1, 2025Apple announces he is stepping down and will retire in spring 2026Apple[1]

Bloomberg's reporting on the March 2025 change said Cook had lost confidence in Giannandrea's ability to execute on product development, while leaving him in charge of AI research more broadly.[18][19] Not all of the work stalled: at WWDC in June 2025 Apple opened its on-device foundation model to third-party developers through a Foundation Models framework accessible from Swift, which Federighi presented as giving developers "direct access to the on-device foundation model" at no inference cost.[21]

Retirement and the breakup of the organization

Apple's December 1, 2025 announcement said Giannandrea was stepping down and would serve as an advisor before retiring in the spring of 2026. Apple credited him with "building a world-class team and leading them to develop and deploy critical AI technologies."[1]

He was not replaced at the same level. Amar Subramanya joined as vice president of AI reporting to Federighi, taking what Apple called "critical areas, including Apple Foundation Models, ML research, and AI Safety and Evaluation." Subramanya had been corporate vice president of AI at Microsoft and spent 16 years at Google, where he was head of engineering for the Gemini assistant. Apple said "the balance of Giannandrea's organization will shift to Sabih Khan and Eddy Cue to align closer with similar organizations"; press reporting identified AI Infrastructure and Search and Knowledge as the units involved. Cook's statement in the release credited Federighi with "overseeing our work to bring a more personalized Siri to users next year."[1][24]

Apple removed Giannandrea from its executive leadership page two days later.[3][25] Bloomberg's Mark Gurman reported on April 13, 2026 that Giannandrea's final days at the company had arrived, keyed to Apple's next stock vesting date of April 15; Gurman described the intervening advisory months as resting and vesting, meaning remaining on the payroll until stock grants vest. The responsibilities Giannandrea still held, covering foundation models, AI testing, and other functions, were split among Federighi, Cue, and Khan.[26] Apple's leadership page lists no executive with an AI title.[3]

Reception

Assessments of Giannandrea's Apple years tend to separate the research organization from the product outcome. The teams under him produced the on-device models, the Neural Engine software stack, and the on-device AI infrastructure that Apple ships across its operating systems, and Apple's own farewell statement pointed to that record.[1][16] The voice assistant he was hired to fix in 2018 was still being rebuilt when he left in 2026.

Reporting on why has pointed in two directions. More than half a dozen former members of Apple's AI team told The Information that the Siri problems stemmed from poor leadership, stringent privacy practices, conflicting personalities, and indecision.[25] Gurman offered a structural reading, arguing that the top of Apple is run by a small group of decision makers that an outsider cannot easily join, which limited how much any hired-in AI chief could change.[26] Attrition compounded the problem: alongside Pang's move to Meta AI, Gurman reported in October 2025 that four more staff had left in September for Meta, OpenAI, and Anthropic.[22][23]

The revamped assistant appeared after his departure. At WWDC in June 2026 Apple announced a new Siri for iOS 27, presented by Rockwell as a more capable assistant with a dedicated Siri app, and built on a second-generation on-device model with onscreen awareness and a collaboration with Google's Gemini. It was scheduled to reach customers in beta later in 2026, initially in English and not in the European Union or China.[30]

After Apple

On April 27, 2026, shortly after he left Apple, Upstarts Media reported that Giannandrea was joining Cusp AI, a Cambridge, England company that uses machine learning to search for new materials. The role was described as part-time advisory work with no formal title, focused on opening a Bay Area office and recruiting AI staff for the company's United States operations; he was reported to be planning to split his time across several AI startups rather than take a full-time job. Both Giannandrea and the company declined to comment.[27][28]

Cusp AI was co-founded by chief executive Chad Edwards and machine learning researcher Max Welling. It raised a $30 million seed round in 2024 and a Series A of more than $100 million announced on September 10, 2025, co-led by New Enterprise Associates and Temasek with participation from NVIDIA's and Samsung's venture arms; at the time of the Upstarts report it was said to be raising $200 million or more at a valuation above $1 billion.[27] The company markets an "AI Materials Foundry" aimed at semiconductors, energy storage, coatings, catalysts, and batteries.[29]
