An Eric Schmidt–Chaired Quantum AI Moon Shot Has a Rocky LaunchAI startup SandboxAQ’s success in raising money this month at a $5.6 billion valuation, despite many uncertainties around its business, showed the influence of big name backers in overcoming risks inherent in highly complex technologies.
The Takeaway
• SandboxAQ was valued at $5.6 billion earlier this month
• Sandbox has faced difficulties commercializing its technology
• Some customers said they had stopped using its tech
In October, on a panel at an investor conference in Riyadh, Saudi Arabia, futurist Peter Diamandis congratulated a technology entrepreneur sitting next to him, Jack Hidary, on the success of his startup, SandboxAQ. “I’ve never seen a company scale revenues as quickly as you have,” said Diamandis, founder of the nonprofit XPrize Foundation.
Also on the panel was Eric Schmidt, former CEO of Google, who has similarly shown his enthusiasm for SandboxAQ—which focuses on two buzzy technologies, quantum computing and artificial intelligence—by becoming one of its most prominent financial backers and its executive chair. Earlier this month, Schmidt participated in a $300 million funding round that valued SandboxAQ at a whopping $5.6 billion, almost double its valuation in a 2022 funding round.
But there are reasons to be cautious about the company’s outlook. According to interviews with more than a dozen current and former SandboxAQ employees, Hidary and the startup have embellished some of its success when communicating with investors.
For example, it said in an investor presentation in recent months that by the end of the year it would reach $50 million in annualized sales—its fourth-quarter sales multiplied by four—and had amassed more than $110 million of signed contracts. In the presentation, it displayed the logos of more than two dozen companies and organizations, including the U.S. Air Force, Wells Fargo, Vodafone and Boeing, alongside text that said SandboxAQ sells “to the largest, most impactful enterprises on the planet.”
Another slide said SandboxAQ, which was selling software for cybersecurity, had “renewed 100% of licensed contracts, with many expansions.”
The implication is that all of the companies mentioned in the presentation are currently customers. But a few of the companies contacted by The Information said they were not customers. Vodafone said it had only tested SandboxAQ’s technology, and a Boeing spokesperson said the company had a “collaboration agreement” with SandboxAQ that gave the company access to its flight test platform, but no longer has a commercial relationship with SandboxAQ. Wells Fargo carried out a proof-of-concept test and no longer uses SandboxAQ’s products, former employees said. The bank declined to comment.
Commercial Struggles
SandboxAQ is also facing difficulties commercializing its technology, according to former employees. The firm develops large quantitative models, numeric-focused alternatives to the large language models that power apps like OpenAI’s ChatGPT. Those LQMs can help pharmaceutical companies discover new drugs or governments to invent new materials, such as plating for military vehicles.
But SandboxAQ has struggled to make its LQMs into one-size-fits-all products for customers, according to former employees. Instead, it has had to painstakingly retool them for specific use cases, such as modeling the effects of a new drug for Parkinson’s disease or discovering materials for a new luxury product made by Hermès, the former employees said. This has made it time-consuming to develop its technology, former and current employees said. Recently, SandboxAQ laid off most of its sales staff.
SandboxAQ’s vice president of product, former Amazon executive Nadia Carlsten, left in August to become CEO of the Danish Center for AI Innovation. Before she left, Carlsten complained to staff that Hidary had exaggerated what the company’s existing products could do for customers, former employees said.
Former employees said SandboxAQ’s internal tool for forecasting potential sales was overly optimistic. The former employees said workers regularly flagged their concerns about the internal projections to Hidary and his direct reports. In recent months, the company has revised those projections, former employees said.
Still, the company has notched some notable successes with customers. It told investors that its largest customer—a laboratory at the University of California, San Francisco, focused on neurodegenerative disease—spent $20 million with SandboxAQ this year. The lab could spend up to $25 million more, depending on the achievement of certain milestones, it said in an investor presentation. And SandboxAQ recently renewed a contract with the U.S. Air Force to develop a new kind of GPS technology.
The situation underscores the inherent uncertainty facing investors trying to assess startups in any sphere of the tech industry, where the underlying technology often is highly complex and understood by few. For that reason, investors often put undue weight on the connections founders have with others, including big-name executives. These issues are exacerbated in AI, where many companies are still struggling to turn cutting-edge developments and world-leading theoretical research into commercial products that can generate a profit.
Whether SandboxAQ can fulfill its ambitions depends largely on Hidary, a well-connected, energetic founder who has dabbled in politics and first made a name for himself during the dot-com boom of the late ’90s. He eventually incubated what became SandboxHQ inside a Google research lab, where he clashed with other staffers, according to people who worked there at the time.
Still, that friction didn’t hurt his relationship with Schmidt, who has stumped for Hidary with prospective investors in recent months. That has helped Hidary attract an all-star list of financial backers including Salesforce CEO Marc Benioff, early Facebook investor Jim Breyer and Meta Platforms AI chief scientist Yann LeCun.
In a video interview earlier this year, Schmidt raved about Hidary. “I’ve been fortunate in my life to work with people much smarter than I—and when I find them I collect them,” he said. “One of them is Jack Hidary.”
In a statement, Breyer said he was “proud to be backing SandboxAQ and its impressive accomplishments,” adding that the startup “is the pacesetter in quantitative AI which impacts large sectors of the economy."
Cutting deals, and spending freely to win them, seems to be another focus for Hidary. His travel and entertainment spending, including bills to wine and dine prospective investors and commercial clients, has been one of the largest items of expenditure at the company, according to former employees and people familiar with the company’s expenses.
Hidary’s willingness to exaggerate SandboxAQ’s successes isn’t uncommon among tech founders, among whom a fake-it-till-you-make-it ethos is commonplace.
“That’s how the deep tech environment often works—you get your narrative out there, make people believe it, raise enough capital to solve enough problems and do that before the chickens come home to roost,” Tanveer Kathawalla, managing partner of Pioneer1890, a venture capital firm that invests in companies catering to government clients.
Representatives for SandboxAQ, Hidary and Schmidt declined to provide comment on the record. A spokesperson for Alphabet, the parent company of Google, declined to comment on the record.
A Mayoral Run
Hidary has said he dropped out early from Columbia University after winning a Stanley Fellowship in Clinical Neuroscience at the National Institutes of Health. A former lab chief for the NIH, Dr David Pickar, said in a statement that while “we usually focus on medical students for this position, we were very pleased to grant this fellowship to Jack.”
Afterwards, Hidary made a dramatic entrance on the technology scene. In 1998, he took EarthWeb, the early internet company he co-founded, public in one of the first and most spectacular listings of that frothy era. But EarthWeb floundered after the dot-com bubble burst in 2000. Hidary sold off an array of the company’s assets and in 2001 agreed to step aside as CEO.
He quickly launched his next venture: Vista Research, a financial research company connecting experts with investors, which McGraw-Hill, a division of Standard & Poor’s, bought in 2005 for a reported $40 million. The company sold the entity at a loss a few years later.
In 2001, Hidary also established a charitable organization, the Jack D. Hidary Foundation, which initially focused on worldwide economic development, according to an archived webpage for the charity, and was later described as having a focus on medical oncology research, according to more recent mentions of the charity by Hidary.
However, a minority of its grants went to cancer-affiliated groups or medical causes over two decades, regulatory filings show. The foundation also ended up giving money to numerous groups associated with Hidary, including $400,000 to OpinionSource, an online opinion aggregation service Hidary founded in 2004.
It also made a $25,000 loan to iAmplify Inc., a now-defunct web-based content publishing company started by Hidary and his brother Murray in 2005. Hidary’s foundation wrote off the loan in 2016, six years after making it, filings show. The foundation, to which Hidary contributed a total of over $2 million over two-plus decades, has reported holding less than $10,000 in assets in each of the past seven years.
In 2013, Hidary parlayed his entrepreneurial reputation and wealth into a run for New York City mayor, with a promise to encourage startup investments in the city. Celebrity economist Nouriel Roubini hosted a penthouse fundraiser for his campaign. One of Hidary’s tongue-in-cheek pledges was to give every New York citizen a pair of Google Glasses, the early smart eyewear from the company, if and when he was elected.
That didn’t happen. Hidary won only around 3,400 votes, coming in fifth place behind the winner, Bill de Blasio.
Moon Shots
Hidary met Schmidt, then Google’s CEO, through their mutual involvement with Diamandis’ XPrize Foundation, a nonprofit that hosts public invention competitions.
Later, Hidary came to know Google co-founder Sergey Brin, who named Hidary as an external adviser in 2016 to help a group of researchers inside X—the Alphabet lab it also refers to as its moon-shot factory—examine the intersection of AI and quantum technologies. Two years later, Alphabet formally hired Hidary to lead what became known as Sandbox@Alphabet, a collection of theoretical experts looking at ways to turn cutting-edge quantum research into products, according to former Google employees.
But Sandbox@Alphabet didn’t quite fit in with the rest of the teams at X. Hidary butted heads with X director Astro Teller over the direction of Sandbox, former employees said.
Sandbox’s interest in working with government entities to develop quantum and cryptography products also put it at odds with the rest of X’s staff, who viewed such military work with suspicion, the former employees said.
Teller didn’t respond to requests for comment.
A former X employee said some members of the Sandbox@Alphabet team were frustrated by the lack of resources coming from Alphabet for Sandbox’s projects. They added that the group also lacked a cohesive plan or strategy, delving into disparate fields such as quantum navigation, drug discovery and chemistry.
One senior X researcher at the time, Guifré Vidal, complained to Hidary about what he saw as Sandbox@Alphabet’s tendency to rush toward creating products before nailing down the science underpinning its projects, two former X employees said.
After several years of overseeing experimentation and research inside X, the frictions inside the group eventually prompted Hidary to strike out on his own. In 2022, he recruited several dozen researchers from Sandbox@Alphabet to join him in a new venture, SandboxAQ. He raised more than $450 million for his startup, a corporate filing shows, valuing it at nearly $3 billion.
Alphabet didn’t invest in the new company, and many employees didn’t follow him to it. But Hidary corralled investments from a coterie of powerful figures, including Schmidt, Breyer and Benioff. T. Rowe Price, its highest-profile institutional investor, put in a relatively small amount of money, a person close to SandboxAQ said.
‘AI or Die’
At SandboxAQ, Hidary has preached a consistent message as he has tried to win business for the company: Even if powerful quantum computers are years away from practical use, it’s not too early for governments and businesses to adopt related technologies.
At the moment, quantum computers are still experimental technologies, but some of the companies investing in the technology are making progress, most notably Alphabet, which announced earlier this month that Willow, its quantum computing chip, had made a significant breakthrough.
Even without yet having quantum computers, SandboxAQ says it uses technologies derived from quantum computing on existing hardware, including chips from Nvidia. Hidary himself has sought to become a public authority on the technologies by writing a textbook on the practical applications of quantum computing in 2019 and a new book, “AI or Die.”
There are signs that SandboxAQ has been overoptimistic in its view of how eager investors are for a piece of the company. While the $300 million it raised was a tidy sum for a young startup, Hidary had originally sought to raise $500 million this year, according to an October update to the company’s corporate charter. Among the new investors in the company was asset manager Fred Alger Management, T. Rowe Price and the sovereign wealth fund of Bahrain.
The $5.6 billion valuation made Hidary—who owns more than 20% of SandboxAQ, a corporate filing indicates—a likely billionaire, at least on paper. The funding round valued SandboxAQ at more than 100 times what it has told investors this year’s annualized sales will be. Its valuation is higher than the combined market capitalizations of Recursion and Schrödinger, two larger, publicly held drug discovery firms.
Current and former employees said poor oversight contributed to a lack of focus at SandboxAQ. They cite a brief effort by researchers—at Hidary’s instigation—to contemplate new lines of work involving AI robotics, which were not the researchers’ areas of expertise and didn’t end up going anywhere. There were other side projects, like AI-powered management tools for distribution of emergency supplies, which former employees said was directed at Covid-19–era health supplies well after the pandemic had subsided.
While Schmidt is chair of the company, its board’s only other members are Hidary and his longtime accountant. That’s a smaller lineup than for other companies that have attained a similar valuation. SandboxAQ also has an advisory board stacked with influential individuals such as Larry Summers and Blythe Masters.
The company appears to have taken steps to keep a tighter lid on costs. In September, SandboxAQ hired Andrew McLaughlin, a former global public policy executive at Google, as its first chief operations officer. One of his first acts was to lay off roughly 10% of SandboxAQ’s staff. That included around 20 employees and leaders focused on securing contracts with government and commercial entities, who represented most of its sales team, according to current and former employees.
