Inside the great AI talent war draining startups, powering Big Tech’s ambitions

The global race to dominate artificial intelligence is increasingly defined not just by capital investment or computing power, but by a fierce, escalating battle for a small pool of elite talent.

As Big Tech companies pour billions into AI development, they are aggressively poaching top researchers and engineers from startups and rivals alike, reshaping the competitive landscape and raising questions about the sustainability of emerging “neo labs” that have attracted record funding but struggle to retain key personnel.

Meta deepens hiring push from Murati’s startup

In the latest sign of intensifying competition, Thinking Machines Lab, the startup founded by former OpenAI chief technology officer Mira Murati, has lost another founding member to Meta.

Joshua Gross, a veteran software engineer who built and shipped the company’s flagship product Tinker from “zero-to-one,” recently joined Meta Superintelligence Labs, where he now leads engineering teams, according to his LinkedIn profile.

Gross’s move marks the fifth founding member from the startup to be hired by Meta, which has been aggressively expanding its artificial intelligence capabilities.

Among those who have already departed is cofounder Andrew Tulloch, highlighting the scale of talent attrition at the high-profile startup.

Thinking Machines Lab, despite raising about $2 billion in a record-breaking seed round last year at a valuation of roughly $12 billion, has increasingly become a target for talent poaching rather than a stable hub for innovation.

The company has reportedly been in discussions to raise further funding at a valuation of up to $50 billion, underscoring investor confidence even as it grapples with internal churn.

Talent exodus reflects broader industry trend

The departures from Thinking Machines Lab are part of a wider pattern across the artificial intelligence sector, where newly formed startups are struggling to compete with the financial muscle of established technology giants.

Several founding team members have already left Murati’s venture to return to OpenAI, including Barret Zoph, Luke Metz, and Sam Schoenholz.

OpenAI has also recruited other key employees from the startup, including cybersecurity specialist Jolene Parish.

Similarly, Safe Super Intelligence (SSI), the startup founded by former OpenAI chief scientist Ilya Sutskever, has faced talent losses, with Meta successfully poaching cofounder Daniel Gross to support its “superintelligence” initiatives.

These moves reflect the growing dominance of a handful of major players—Meta, Microsoft, Google, and OpenAI—in the race to build advanced AI systems, as they leverage their financial resources to secure the industry’s most sought-after expertise.

Compensation gap widens between startups and Big Tech

Industry observers say compensation is a key factor driving the talent shift.

While startups such as Thinking Machines Lab can offer equity stakes that may eventually be worth billions, they often struggle to match the immediate financial incentives provided by larger firms.

According to reports, companies including Meta, Google DeepMind, and OpenAI are offering compensation packages in the high six- and seven-figure range, with some deals reportedly reaching hundreds of millions or even billions of dollars for top-tier researchers.

The structure of these packages also gives established firms an advantage.

Public companies can offer stock options with accelerated vesting schedules, allowing employees to convert equity into cash within months.

In contrast, stock options from early-stage startups are seen as riskier, as their long-term value depends on future performance and market conditions.

This imbalance has made it increasingly difficult for “neo labs” to retain talent, even after securing significant funding.

Big Tech strikes unconventional talent deals

The scramble for AI expertise has also led to unconventional hiring arrangements, with major technology companies effectively acquiring talent through strategic partnerships and licensing deals.

In 2024, Microsoft hired Mustafa Suleyman and Karén Simonyan, co-founders of Inflection AI, along with several members of their team.

The deal, which included a reported $650 million payment to the startup, allowed Microsoft to integrate Inflection’s technology while absorbing much of its workforce.

Amazon has pursued a similar strategy, reaching an agreement with AI startup Adept to license its technology and bring in key members of its team, including co-founder and chief executive David Luan.

Although Luan later left Amazon, the deal highlighted the extent to which companies are willing to go to secure both talent and intellectual property.

Companies such as Google and Microsoft have intensified their hiring efforts in recent times.

Google last year secured a deal worth around $2.4 billion to bring in Varun Mohan, co-founder of AI coding startup Windsurf, in what was called a “reverse acquihire” where the company did not buy Windsurf, nor scooped up a stake in it, but paid a hefty fee to license its technology and bring key talent on board.

Microsoft AI also recruited dozens of researchers from Google DeepMind.

Meta has been particularly aggressive, with chief executive Mark Zuckerberg spearheading a major hiring drive to build out the company’s Superintelligence Labs.

The push included a $14 billion investment in Scale AI and the recruitment of its co-founder, Alexander Wang.

Intensifying competition for scarce expertise

At the heart of the talent war is a relatively small group of highly specialised researchers capable of developing advanced large language models and other cutting-edge AI systems.

Estimates suggest there are fewer than 1,000 such individuals globally, making them among the most valuable assets in the technology industry.

The competition for this talent pool has driven compensation to unprecedented levels.

OpenAI chief executive Sam Altman has said that the rivalry has escalated to the point where signing bonuses of up to $100 million have been offered to lure top researchers.

The broader compensation landscape reflects similar trends.

OpenAI’s average stock-based compensation reached about $1.5 million per employee in 2025, one of the highest levels ever recorded for a technology startup.

Challenges for emerging AI labs

For startups like Thinking Machines Lab, the ongoing talent drain poses significant challenges.

While large funding rounds provide the capital needed to build infrastructure and develop products, they do not necessarily guarantee the ability to retain the human expertise required to execute those plans.

The situation underscores a broader tension in the AI ecosystem.

On one hand, venture capital continues to flow into new entrants, reflecting optimism about the transformative potential of artificial intelligence.

On the other hand, the concentration of talent within a handful of dominant firms raises concerns about competition and innovation.

As the industry evolves, the ability to attract and retain top researchers is likely to remain a decisive factor in determining which companies emerge as leaders.
