Project Prometheus (Bezos)

Prometheus, known until 2026 as Project Prometheus, is an artificial intelligence startup co-founded by Jeff Bezos, who serves as its co-chief executive alongside the scientist Vik Bajaj. The company was first reported by The New York Times on November 17, 2025, which described a venture that had launched with roughly $6.2 billion in funding and a focus on "physical AI" for engineering and manufacturing across sectors such as computers, aerospace, and automobiles ^[1][2]. The venture marks Bezos's most significant operational role at a company since he stepped down as chief executive of Amazon in 2021 ^[2][3]. In May and June 2026 Bezos described its goal publicly for the first time as an "artificial general engineer," a set of AI tools meant to help engineers design and manufacture physical objects, and said the company has "nothing to do with robotics" ^[10][11]. On June 11, 2026, it announced a $12 billion Series B round that valued it at roughly $41 billion ^[11][12].

For its first months Project Prometheus operated with an unusually low public profile for a company of its size, and much of what is known still comes from press reporting that cites anonymous sources rather than from the company itself. The co-chief executives began speaking on the record in mid-2026, but as of those June 2026 interviews the company had not released a product or given a product timeline ^[11][12].

Disambiguation: This article concerns the Bezos-backed AI startup. It is unrelated to Prometheus, the AI data center cluster that Meta is building in Ohio, which is a separate project with a coincidentally identical name ^[4].

Overview

Prometheus is positioned around the idea of applying artificial intelligence to physical engineering and manufacturing rather than to text or imagery alone. Early reporting described the company as pursuing "physical AI," a category in which models learn from real-world experimentation and sensor data instead of relying solely on digital corpora ^[1][2]. This places it in the broader area sometimes called physical AI, and observers compared its likely research direction to that of other physics- and science-oriented labs such as Periodic Labs ^[1]. Bezos later narrowed the description: in a May 2026 interview he called the product "a very, very modern version" of CAD (computer-aided design) software, while cautioning that he was "really oversimplifying" ^[10].

At launch the company was described as one of the best-capitalized early-stage AI ventures in the world, owing to the roughly $6.2 billion it had reportedly raised ^[1][3]. After its June 2026 Series B, The Next Web reported that its total funding exceeded $18 billion ^[18]. It is headquartered in San Francisco, with additional teams in London and Zurich ^[5][12], and in August 2026 it was reported to have leased a 100,000-square-foot industrial site in West Oakland ^[19].

Name

The company was first reported under the name Project Prometheus ^[1][2]. By June 2026 it had dropped "Project" from its name and was presenting itself simply as Prometheus ^[12]. Its LinkedIn page describes its mission as "AI for the physical economy" ^[11].

Founding and leadership

Prometheus is led by two co-founders who share the chief executive role.

Bajaj's earlier work at Google's X has been linked in some reporting to early efforts that became the self-driving car program Waymo: Fortune wrote that he worked closely with Google co-founder Sergey Brin on efforts including the self-driving car that became Waymo ^[3]. The precise extent of that involvement is described differently across accounts and is best treated with caution. His most consistently reported credentials are his physics and chemistry training, his time at X, his co-founding of Verily, and his leadership of Foresite Labs ^[1][6]. Foresite Capital's biography of Bajaj also lists him as a former chief scientific officer of GRAIL, chair of Verily's scientific advisory board, an adjunct associate professor at Stanford, and a co-founder and director of Xaira Therapeutics ^[20]; his Stanford profile lists him as an adjunct professor in the radiology and molecular imaging program ^[21]. Wired reported that Bajaj and Bezos had previously been connected through Bezos's investments in biotech companies Bajaj helped start or run, such as Grail and Xaira ^[14].

Bezos has described his own involvement as starting earlier than the November 2025 reports. Speaking in June 2026, he said he began in late 2024 as a founding investor alongside Bajaj and then "became so impressed by what was happening and the potential that I decided I couldn't sit on the sidelines and I needed to jump in with both feet" ^[12]. He told CNBC that "Prometheus is the bulk of my time," while he also spends time on Blue Origin and on AI at Amazon, where he remains executive chairman ^[11].

For Bezos, the venture represents a return to a hands-on executive seat. The New York Times and subsequent coverage framed his participation as notable precisely because he had largely stepped back from day-to-day company management after handing the Amazon chief executive role to Andy Jassy in 2021 ^[2][3].

Other people publicly linked to the company include Robert Nelsen, co-founder and managing director of ARCH Venture Partners, whom the Financial Times identified as a director of Project Prometheus ^[15]. According to Wired, Ashish Vaswani and Jakob Uszkoreit, two co-authors of the 2017 transformer paper "Attention Is All You Need," became founding advisers to the company while running their own startups, and former Nvidia senior research scientist Kamyar Azizzadenesheli joined in early 2025 ^[14]. In April 2026, AI Magazine, citing the Financial Times, reported that Kyle Kosic, a co-founder of xAI who had later joined OpenAI, had been recruited to work on AI infrastructure at Prometheus ^[8].

Funding

The figure most often associated with Project Prometheus is approximately $6.2 billion raised at or around its launch. This number originated with The New York Times report of November 17, 2025, which attributed it to people familiar with the matter; Fortune characterized the funding as including "some from Bezos himself," without specifying the precise share contributed by Bezos or the identities of other backers ^[1][2][3]. In February 2026 the Financial Times reported that this raise had valued the company at $30 billion ^[15], and GeekWire later described Bezos as the largest backer of what it called the company's $6.2 billion Series A ^[12].

Later reporting pointed to a substantially larger follow-on raise. On April 21, 2026, the Financial Times reported, and Bloomberg relayed, that Project Prometheus was close to finalizing a roughly $10 billion funding round that would value the company at about $38 billion, with JPMorgan and BlackRock named among the investors; the round had not been finalized at the time ^[7][8]. Bloomberg subsequently reported that the company had closed a $10 billion round at a $38 billion valuation ^[10]; Pulse 2.0, summarizing that report, said the round had no lead investor and brought total funding to more than $16 billion ^[17].

On June 11, 2026, Prometheus announced that it had raised $12 billion in Series B funding at a valuation of roughly $41 billion ^[11][12]. Investors in the round included JPMorgan, BlackRock, Goldman Sachs, DST Global, and ARCH Venture Partners, according to Axios as cited by GeekWire, and Bezos said he had participated in the round as well ^[11][12]. The Next Web described the $41 billion figure as the final close of the round that had been reported in April at $38 billion ^[18]. Bezos said a large part of the new money would go to compute, explaining that "what we're doing is very compute intensive and we need to, you know, create that data" ^[11]. Asked about an eventual initial public offering, he said it was "too early to think about that" ^[12].

The 2025 and April 2026 amounts come from press accounts citing unnamed sources rather than from official company disclosures, so they should be read as reported figures. The June 2026 round was announced by the company and discussed on the record by Bezos, but the full investor list was not disclosed, and the coverage did not specify whether the valuation was pre-money or post-money ^[11][12].

Proposed acquisition vehicle

Separately from the lab's own funding, Bezos and Bajaj have been reported to be raising money for a vehicle that would buy industrial companies. In February 2026 the Financial Times reported that Project Prometheus was raising "tens of billions of dollars" to buy businesses disrupted by AI and then use the technology to improve their margins, and two people interviewed by the newspaper described Project Prometheus as a "manufacturing transformation vehicle" ^[15]. In March 2026 The Wall Street Journal reported that Bezos was in talks to raise $100 billion for a fund to acquire manufacturing companies and infuse them with AI, and that he had met large asset managers, including on trips to the Middle East and Singapore ^[16].

In the June 2026 interviews, the co-chief executives declined to discuss this second part of their plan in detail ^[13]. Addressing the reports, Bezos said Prometheus may buy parts of companies that could benefit from its technology and help them improve their manufacturing processes ^[12].

Focus

Project Prometheus was first reported to be building AI products for engineering and manufacturing, with named target sectors including computers, aerospace, and automobiles ^[1][2][3]. The unifying theme across early reporting was "physical AI": systems intended to understand and act in the physical world, trained on multimodal data gathered from real-world interactions rather than on text alone ^[5].

Bezos gave the first on-record description of the work in a CNBC interview on May 20, 2026. When the interviewer described the company as being about AI robotics, he replied: "we have nothing to do with robotics." He said Prometheus was developing an "artificial general engineer" and building next-generation tools for designing physical objects, and that those tools would "help companies like Blue immensely," referring to Blue Origin, while arguing that the company deserved its own focus rather than being housed inside Amazon or Blue Origin ^[10]. GeekWire noted that much earlier outside reporting had characterized the company as focused on robotics and manufacturing automation, partly from analysis of its hires' LinkedIn profiles ^[10].

In a second CNBC interview on June 11, 2026, the two co-chief executives said Prometheus is building AI tools to help engineers design and manufacture physical products more easily and quickly, and Bezos described the goal as speeding up the "invention loop" ^[11]. CNBC reported that the company works on AI models for physical tasks including engineering, manufacturing, and drug design ^[11]. Bajaj used the example of a jet engine, which takes teams of engineers a decade or more to design, prototype, and manufacture, and said that "what has changed in the last few years is the ability to formulate even something as complicated as that, from design to manufacturing, as an end-to-end AI problem" ^[12]. According to The Wall Street Journal, as relayed by PYMNTS, Bajaj said the company aims to build AI systems that cover the whole engineering process, from designing products and predicting their performance to manufacturing them ^[22].

On data, the founders told Semafor that they had assembled a dataset drawn from established laws of physics and from testing results supplied by manufacturing companies they declined to name. "We create that data for the most part ourselves, but we also obtain it where we can from other sources," Bajaj said ^[13]. Semafor reported that the company operates a large GPU cluster for internal use and also buys compute from other providers ^[13]. Bezos told CNBC that Prometheus gets compute "from a multitude of sources," Bajaj added "including AWS," and Bezos said the company would remain "at arm's length" from Amazon ^[11]. The co-chief executives declined to give a product timeline, saying only that early rollouts were coming ^[12].

As part of assembling its capabilities, Project Prometheus acquired General Agents, a startup founded by Sherjil Ozair, who had previously held senior research roles at DeepMind and Tesla ^[14]. Wired reported in November 2025 that Delaware corporate filings showed Bajaj forming an entity to acquire General Agents in June 2025, the morning after a San Francisco dinner that Ozair attended, and that the entity merged with the startup four days later; the terms were not disclosed ^[14]. General Agents had released Ace, which it described as "a real-time computer pilot," in April 2025: a computer-use agent that takes over a computer and carries out actions based on a user's prompts ^[14]. Its co-founder William Guss, a former OpenAI research scientist, also joined Prometheus ^[14]. How Ace fits into Prometheus's plans was not explained ^[14].

The work draws on talent recruited from established AI organizations. By late 2025, reporting described a team approaching 100 people, with researchers drawn from firms including OpenAI, Google DeepMind, and Meta's AI efforts; later accounts placed the headcount above 120 ^[1][6][5]. In June 2026 Bezos said the company had about 150 employees, and CNBC reported that it had also recruited from Nvidia ^[11].

Facilities

The company is based in San Francisco, where CNBC interviewed the co-chief executives at its headquarters in June 2026, and it has teams in London and Zurich ^[11][12]. In August 2026 The Real Deal, citing the San Francisco Business Times, reported that Prometheus had signed a lease for 100,000 square feet at the former American Steel Blocks site at 1960 Mandela Parkway in West Oakland, after earlier leasing roughly 30,000 square feet of offices at 101 Mission Street in San Francisco and searching for an industrial facility ^[19]. The property's marketing materials advertise 8,000 amps of power ^[19].

What is known and what is not

Project Prometheus has been characterized as secretive, and for much of its first year it had no conventional public website and operated largely in stealth ^[5][10]. When asked about this in June 2026, Bezos said: "We're not being secretive, right? We're just being heads down and trying to do the work" ^[11]. The clearest, most consistently corroborated facts are the dual leadership of Bezos and Bajaj, the rough $6.2 billion launch funding, the $12 billion Series B announced in June 2026, the engineering-and-manufacturing focus, and the November 2025 timing of the first report ^{[1][2][3][11][12]}.

Several details remain comparatively thin or single-sourced and warrant caution. These include the full investor list, the exact scope of products under development, the company's specific technical roadmap, the size and status of the proposed acquisition vehicle, and the finer points of Bajaj's earlier project history. Bezos said in June 2026 that it was still "premature" to disclose what the company had accomplished ^[11].

Significance

The venture drew attention chiefly because of who is behind it and how it is structured. Bezos taking a co-chief-executive title represents an unusual re-entry into operational leadership by one of the most prominent figures in technology, and it did so in service of physical-world AI rather than the consumer software or cloud businesses with which he is most associated ^[2][3]. The scale of the funding, both the initial round and the much larger follow-on, also placed Project Prometheus among the most heavily capitalized young AI companies, intensifying discussion about the amount of capital flowing into frontier AI ventures ^[3][7].

Coverage has also noted skepticism. Semafor wrote that the limited details about the lab's work leave Bezos open to critics who say the venture may amount to using his clout to draw institutional money into AI, and recalled that Elon Musk had called Bezos a "copycat" in a post on X after news of the venture leaked in 2025 ^[13]. Pulse 2.0 observed in April 2026 that the company had reached its valuation without having released products, published research, or generated revenue ^[17].

Context

Project Prometheus emerged during a period of rapid capital formation around AI for the physical world, including robotics, world models, and laboratory automation, in which several well-funded labs sought to extend machine learning beyond language and images into manufacturing, science, and engineering. Its emphasis on learning from real-world experimentation situates it alongside other efforts exploring world models, even though Bezos has said the company itself is not building robots ^[10]. Bezos has separately invested in robotics companies, including Physical Intelligence and Generalist AI ^[22]. The episode also fed a wider conversation, which Bezos himself addressed in 2025 remarks at Italian Tech Week describing an "industrial bubble" in AI investment, about whether the surge of funding into such companies was sustainable ^[3].
