As their heads were measured and fitted for custom-made felt cowboy hats, the 100 or so guests assembled in Utah’s scenic Wasatch Mountains in November 2023 had ample reason to feel special. The group of AI executives, venture capitalists, government officials, and policy folks, had been handpicked to attend a secretive three-day retreat focused on the national security implications of artificial intelligence.
Presiding over the confab was Alexandr Wang, the young CEO of data-labeling AI startup Scale AI. Wang’s company was seven years old and already worth $13 billion at the time, but the event at the Montage Deer Valley, cohosted with longtime Scale AI angel investor Nat Friedman, was clearly intended to signal Wang’s status as more than just the latest Silicon Valley wunderkind. Sitting alongside gray-haired Pentagon top brass, the 26-year-old Wang held forth on the U.S.-China AI arms race and other weighty topics.
One attendee recalled Wang as a well-spoken master of ceremonies, but with an agenda to sell. “My impression is that [it] was a bit of a sales event to show off to his investors and government customers that he had a fantastic network,” he told Fortune. Another attendee said Wang was a “generous” host, but added he was unsettled by the “theatrical hawkishness”—what he described as a “fairly transparent effort to ingratiate himself with the national security establishment.”
In an unexpected, dramatic follow-up as attendees flew home from Utah, the day after the event, OpenAI CEO Sam Altman was abruptly fired. Within 48 hours, as chaos unfolded inside OpenAI’s nonprofit boardroom, Wang and Friedman were both quietly approached to serve as interim CEO. Both declined.
By then, however, it was clear: Wang, who was already known in some D.C. circles as Washington’s “AI whisperer,” had come a long way since cofounding Scale AI in 2016 with Lucy Guo, back when he was a 19-year-old MIT dropout building a data-labeling startup for self-driving cars (to help teach AI systems to know the difference between, say, a stray, windblown plastic bag and a pedestrian).
In just a few years, he had transformed Scale AI into a generative AI powerhouse—first by hiring tens of thousands of workers to manually sift through and label massive datasets to help train AI models, then to run model evaluations and fine-tune systems for companies like OpenAI, SAP, and Toyota through techniques like reinforcement learning. In 2021, at just 24, he briefly became the youngest self-made billionaire after a funding round which valued the company north of $7 billion.
But when news emerged this month that Wang was joining Meta to be part of a new “superintelligence” team reporting directly to Mark Zuckerberg, part of a $14.3 billion acqui-hire, industry watchers were still stunned.
The deal, which values Scale AI at $29 billion and Wang’s personal stake at a reported $5 billion, is Meta’s largest outside investment ever. The stakes couldn’t be higher for Meta, as it transitions its business into the rapidly evolving AI era and races against giants like Google and OpenAI to develop all-powerful AGI (artificial general intelligence) and “superintelligence” capabilities. In Wang, and in the 49% stake in Scale AI that Meta is acquiring, Zuckerberg appears to see a secret weapon. There are even rumors that Wang could be crowned the head of Meta’s entire AI operations—rumors that have only added to the consternation among those wondering how a young entrepreneur whose business relies more on manual labor than large language models fits into Meta’s quest for AI supremacy.
Fortune spoke to more than a dozen people close to Wang, including current and former Scale AI employees, investors, acquaintances, and competitors, to trace how the 28-year-old MIT dropout built the business at the center of one of the richest deals in the AI boom, and to understand why Meta is betting so much on it. Meta declined to comment or to make Wang available.
“Alex is a great recruiter, a really savvy commercial person,” said one former Scale AI manager. “Who knows if it’ll work out? Maybe he builds a better AI team into something Herculean, maybe not, but you’re gonna bet on someone to do it. There’s probably a handful of people in the world that you bet on to do it. I think he’s probably one of them.”
When Zuck met Alexandr
Meta’s relationship with Scale AI dates back to 2019, when the social media company began using Scale as a data provider for its AI efforts. In 2024, when Scale AI raised $1 billion in its Series F funding round, Meta was among the investors, scooping up half-a-million shares of the startup’s stock.
Zuckerberg and Wang began spending more time together beginning in April, when Zuckerberg reached out and expressed a desire to work more closely, according to a source familiar with the negotiations. The Meta CEO, who had once also held the title of the world’s youngest self-made billionaire, began inviting Wang to powwow with him at his houses in Lake Tahoe and Palo Alto, with Zuckerberg soon coming to trust Wang’s opinion. Advisors say that Zuckerberg would sometimes reference Wang’s views in conversations with them, The Information reported.
The conversations between the two CEOs came at a time when Zuckerberg was growing frustrated with Meta’s struggles keeping up with rival AI labs such as OpenAI, Anthropic, and Google DeepMind. Meta had succeeded in creating a family of successful open-source AI models, called Llama, but never seemed able to stay in front of the pack for long. OpenAI, Anthropic, and Google DeepMind would inevitably surge past Meta with AI models that captured more attention and mindshare among AI developers.
With the release of Llama 4 in April 2025, Meta’s malaise became a crisis. Allegations of possibly inflated performance metrics, a rushed release, and a lack of transparency, along with indications that Meta was failing to keep pace with open-source AI rivals like China’s DeepSeek, led many in the industry to proclaim Meta’s latest AI model a flop. (Meta has called claims that it gamed performance metrics “simply not true,” and ascribed reports of Llama 4’s “mixed performance” at launch to early bugs.)
To regain the edge, Meta has moved aggressively to amass AI talent and realign its efforts. News reports this week have claimed Meta recently held talks to acquire AI firm Perplexity, as well as Safe Superintelligence, the startup founded by former OpenAI chief scientist Ilya Sutskever. According to one source familiar with the matter, Meta is currently in talks to acquire the AI venture capital fund managed by Friedman, the Scale AI investor, and Safe Superintelligence executive Daniel Gross. The discussions with Scale AI appear to have occurred in parallel to many of Meta’s other talks.
Wang resisted Zuckerberg’s initial proposal that he join Meta, saying that if he were to leave his startup, any deal would have to involve an immediate (and worthwhile) outcome for Scale AI’s investors, according to the source familiar with the negotiations. Throughout May, the two CEOs held on-and-off discussions, going from a proposed $5 billion Meta nonvoting investment in Scale AI to the eventual arrangement of Meta investing $14.3 billion for 49% of Scale in nonvoting shares with potential future conversion. (The deal also includes a poison pill provision: If Wang leaves Meta, the shares would convert at a rate of 1.5, creating additional dilution, incentivizing Wang to make a long-term commitment to Meta.)
Some sources close to Wang, whose first name is spelled without the second “e” to give it the eight characters associated with good fortune in Chinese culture, said the deal he reached with Zuckerberg shows his commitment to doing right by his investors and employees rather than abandoning them for his own lucrative exit. Still, the news that Wang was leaving came as a big surprise to many people connected to Scale AI and its CEO.
“It was a total shock,” said the former Scale AI manager, who left the company last month. “I never thought about the idea of Alex leaving Scale, especially when we’d just announced the tender offer at a $25 billion valuation. I think about how fast it all happened.”
Scale AI responded to Fortune’s request for comment by pointing to a blog post from new CEO Jason Droege that affirms the company’s continued independence, its commitment to not favoring any specific AI models, and hinting at upcoming announcements.
A perfectly timed pivot to success
After the deal was publicly announced, Wang addressed Scale AI employees at the company’s South of Market office in San Francisco. He got a standing ovation as he walked down a winding staircase to the office building’s atrium. He cried at times as he spoke to employees about his time at Scale AI and starting the company when he was a freshman in college.
Perhaps Wang was thinking even further back to his childhood, as the son of immigrant parents who were nuclear physicists at Los Alamos National Laboratory in New Mexico, which had served as the top-secret site for developing the first atomic bombs, led by J. Robert Oppenheimer.
“In my town, basically everybody’s parents worked for the National Lab,” he told Fortune in an interview last year. “Every adult around me was a scientist who had made the pledge to use their scientific capability and their powers for enhancing technologies that would ensure the continued security of the United States.”
That upbringing provided the template Wang used to turn Scale AI into a successful business, said Jared Friedman, a group partner at Y Combinator. “He built an extremely talent-dense team and intense culture with people similar to him, other exceptional math and CS [computer science] students,” Friedman said.
Wang, who competed in national math competitions in high school, dropped out of MIT after one year to pursue the startup dream, teaming up with Lucy Guo, a product designer at Quora, who had herself dropped out of Carnegie Mellon to pursue a Thiel Fellowship and had been Snap’s first female designer. The duo originally planned to create tech for a doctors’ concierge service, but after joining startup accelerator Y Combinator in the summer of 2016, they eventually pivoted to data labeling.
“They were originally working on completely different ideas and spent most of the first summer just figuring out what to build,” recalls Friedman, who served as Wang and Guo’s partner at Y Combinator in 2016.
Once it pivoted to data labeling, Scale AI found the perfect customer base in the rapidly expanding, and well-funded, group of startups working to build self-driving vehicles.
Wang embodied the company credo of “Ambition shapes reality,” said an early employee who left in 2022. “Alex himself would get deeply involved in customer engagements when needed, including deep-diving into both technical challenges and helping to network and negotiate with higher-ups on the business side to help us win customers and new business.”
Another source, the former Scale AI manager, described two-hour-long daily meetings “where we would review every single account.” The routine was not universally enjoyed inside the ranks, the person said, “but honestly, in retrospect it forced everyone to be very rigorous.”
Tensions between the two cofounders soon surfaced as the company grew. Guo had recruited Wang, and she was the original CEO. But the two founders could not get along, clashing over how they each deemed their counterpart was handling their duties, according to a source familiar with the matter. The board sided with Wang, who became CEO, and Guo left the company in 2018, according to this person’s account. Guo told Fortune that when Wang proposed taking on the CEO role after the Series A, believing “he’d be better as the face of an API company,” she agreed. “I wasn’t title-centric and was fine with it,” she said in an email. Guo received $750 million as a result of the Meta deal. She did not comment on the current state of her relationship with Wang.
In recent years, Scale AI has run into concerns over its labor practices with the estimated tens of thousands of contractors it employs around the world to manually label data and review images. A Department of Labor investigation was opened in 2024 and closed in May regarding the company’s adherence to the Fair Labor Standards Act, particularly around fair pay and worker classification. There are currently two labor lawsuits against Scale AI that are ongoing. Glenn Danas, partner at Clarkson Law Firm—which brought those cases against the company—estimates Scale AI’s contractor workforce could amount to roughly 60,000 people.
‘He’s not just a salesperson’
One thing that makes the Meta/Scale AI deal notable is that Wang had always emphasized that he is not a researcher, and that Scale AI was not building AI models. Instead, it wanted to provide the entire generative AI ecosystem with high-quality data to train its models.
“We’re not out there developing a leading large language model,” Wang told Fortune last year. “But we do serve the entire ecosystem. Nearly every major large language model is built on top of our data foundry.”
Scale AI was also agnostic when it came to working with customers. It did some of the earliest experiments on reinforcement learning from human feedback (RLHF), with OpenAI in 2019, with the team that later became Anthropic. Scale AI continued collaborating with both AI startups. “We’re both neutral across the entire ecosystem, and we’re able to have very strong relations with every relevant company in the AI ecosystem across the stack,” Wang said.
Scale AI has said it will continue to operate as an independent company (with Wang as chairman), serving other customers. Under the terms of the deal, Meta will spend a minimum of $500 million a year for Scale AI data over the next five years, according to the source familiar with the negotiations. But the perception of neutrality now looks all but dead. Following the announcement, news reports said that both Google and OpenAI were planning to end their relationship with Scale AI. Some industry observers speculate that Meta’s real strategy all along was a data land grab, a move to secure a major source of one of the vital components for building AI models—and to deprive others of it.
But several industry insiders whom Fortune spoke to were skeptical of the theory. Ryan Kolln, CEO of Scale AI competitor Appen, said he doubts the Meta/Scale deal is about consolidating data vendors or starving competitors seeking data. There’s a risk in doing that because there’s a strong benefit to having diversity in data, with vendors that have different specialties and expertise, he said.
So what is the key thing Zuckerberg is getting for his $14.3 billion?
Several sources close to the companies said they had heard that Wang is being considered as a potential leader for Meta’s entire AI organization—a far more powerful remit than the “superintelligence” team, which some news reports have said will consist of 50 people and be helmed by Wang.
Erik Meijer, a former engineering leader at Meta, said he would not be surprised by a move to make Wang a “chief AI officer” of all of Meta. “Heaping everything into a single org makes sense,” he said. “In fact I would be surprised if Mark [Zuckerberg] would make such a big investment and then not do a full-on reorg putting all AI efforts in one place.”
Meta’s sprawling AI kingdom includes the product-focused generative AI team, the AGI Foundations unit focused on further Llama development, as well as FAIR (Fundamental AI Research), which was founded by Yann LeCun, the AI “godfather” who remains Meta’s chief AI scientist. There is also a stand-alone Business AI product team helmed by former Salesforce AI head Clara Shih.
That said, Wang would be an unorthodox choice for the top role, given that he is not a computer scientist. Whether the PhDs and other AI researchers working at Meta would accept Wang as their leader is hardly a sure thing. “Nope,” one current Meta AI researcher said flatly. Wang is a businessman without a strong record working with AI models, the Meta researcher said. A former Meta AI researcher who worked in Meta’s FAIR group concurred: “He is not going to be accepted easily.”
It’s a warning Zuckerberg may well heed, given that Meta’s research lab is already bleeding talent—11 of the original 14 Llama authors have left to join competitors. On the other hand, Wang’s defenders point out that while not a computer scientist, he is more than capable of getting in the AI weeds.
“We forget sometimes he is a very technically capable guy,” said the former Scale AI manager. “He’s not just a salesperson. He’s incredible at it, but he’s not just a salesperson.”
Navigating an unpredictable platform shift
With more than $164 billion in annual revenue, Meta knows all too well that it takes something truly unique to move the needle in its business. And in paying up for Wang and Scale AI, Zuckerberg is likely betting that the real value transcends any simple categories.
One source close to Wang told Fortune that the surprise and confusion stems from the fact that Wang does not fit into the typical tech-world archetypes. “Silicon Valley is good at putting people into boxes. They like to say, ‘This person is a technical person, this person is a businessperson,’” he said. “Alex is truly a man of one.” And that kind of asset is especially valuable as the landscape changes.
If AI proves as game-changing as some expect, it will be far more consequential than any of the previous platform shifts that have rocked the tech industry, bringing hard-to-predict risks and opportunities. The advent of AI is already thawing the massive military contract market that Silicon Valley companies were once largely frozen out of, with Meta forging ties with drone-maker Anduril while rivals like OpenAI clinch Pentagon deals of their own.
“My very, very deep sense is that Meta is actively exploring, maybe even advanced in terms of actively exploring, wanting to play a significant leadership role in the national security of the United States,” said one former Department of Defense official.
As Wang demonstrated at the Utah confab in 2023, and in Scale AI’s full-page Washington Post ad in January (“Dear President Trump, America must win the AI War”), Meta’s new investment is well-positioned on that front. It has also not gone unnoticed that Michael Kratsios, the Trump administration’s director of the Office of Science and Technology Policy and science advisor to the president, worked at Scale AI in between the two Trump terms.
“He’s been very smart and extremely clever,” the former DOD official said of Wang. “He seemed to lean into something that a lot of people have a little bit of a revulsion against, which is, engage in the politics of Washington. I think Alex, whether it’s by generation or personality, or whatever, he really got that that needed to happen—he seemed to have a real sixth sense.”
But while Meta could use all the help it can get in D.C. (“No one loves to hate anyone more than Washington loves to hate Zuckerberg; it’s kind of a pastime for some people,” a Beltway insider said), Wang will ultimately need to deliver more than the services of a lobbyist for the partnership with Zuckerberg to be successful. To Wang’s fans, including one source who has known Wang for about a decade, his versatility will help Meta open doors and navigate whatever challenges lie ahead: “He’s better at the point of contact on any problem more than anyone I’ve ever seen.”
Zoom out for a longer-term view, and this person echoed a common sentiment, that Wang is just getting started. “He may start another company, or maybe a bunch of companies,” the person said. “Over time, he has a chance of being a main character in Silicon Valley at the highest levels for the next 30 years.”
