Google was not spared by this year’s AI talent wars.

The Gemini creator lost employees from its AI and cloud business, even though the company also made significant hires from other Big Tech companies.

Unlike Apple, which mostly lost AI talent to Meta, which splurged big on recruitment this year, most significant departures from Google ended up at Microsoft.

Google DeepMind’s rivalry with Microsoft’s AI unit is one between two DeepMind cofounders who parted ways. Mustafa Suleyman, now steering Microsoft’s consumer AI push, and Demis Hassabis, the current CEO of Google DeepMind, launched DeepMind alongside researcher Shane Legg in 2010. They built a research lab so influential that Google bought it for more than $500 million in 2014.

But a decade later, Suleyman departed Google and founded Inflection AI. He and most of his team were subsequently absorbed by Microsoft in a $650 million “acqui-hire,” which made him the AI lead of the company.

The competition for AI recruitment continues to intensify as hiring cools in the Big Tech job market. Here’s a running list of the AI talent Google has lost this year and where they’ve ended up.

In July, Subramanya left his position as vice president of engineering at Google to join Microsoft as its corporate vice president of AI. He had been with Google for more than 15 years. In December, it was announced that he was joining Apple.

Adam Sadovsky

Sadovsky was a distinguished software engineer and senior director at Google for nearly 18 years before joining Microsoft as the corporate vice president of its AI division in June.

Sonal Gupta

Gupta was a principal engineer at Google DeepMind before leaving for a position as technical staff on Microsoft’s AI team. Prior to Google, Gupta also worked for Meta.

Rothfuss was a research scientist at Google DeepMind before leaving in May to join Microsoft as a member of technical staff on the company’s AI team.

Management and executives

Lee was the senior director of corporate development for Google Cloud and DeepMind.
