Execs and AI researchers who have left Apple — and the one company that’s snapped many of them up

• Apple has lost over a dozen executives and researchers this year, with others announcing their retirement.
• Meta hired nine of these former Apple employees.
• Others left for AI startups, OpenAI, or simply retired.

They're not called the AI talent wars for nothing.

With Big Tech firms scrambling to attract top talent, executives and artificial intelligence researchers have done a lot of job-hopping this year, and Apple employees were no exception.

The company has lost over a dozen employees who worked on its AI projects, from executives to scientists to engineers, and even its AI chief, John Giannandrea, who announced this week he was stepping down from the role.

One competing tech company has been the biggest beneficiary of the departures at Apple: Meta.

Nine of the former Apple employees listed below have landed at Meta, where CEO Mark Zuckerberg has been offering notoriously large pay packages and incentives to attract AI talent from across the industry.

Other ex-Applers jumped ship to join OpenAI.

To be sure, Apple has done some of its own recruiting too; its new vice president of AI is Amar Subramanya, who left Google in June to join Microsoft, only to join Apple several months later. Meta's top lawyer, Jennifer Newstead, is departing to become Apple's general counsel.

Here's a running list of the AI talent Apple has lost this year and where they've ended up.
