**Discovery Loop** is an American artificial intelligence startup founded by [Jeff Dean](https://aiwiki.ai/wiki/jeff_dean), [Sanjay Ghemawat](https://aiwiki.ai/wiki/sanjay_ghemawat), [Oriol Vinyals](https://aiwiki.ai/wiki/oriol_vinyals), and [Quoc Le](https://aiwiki.ai/wiki/quoc_le), four of the most influential researchers and engineers in the history of [Google](https://aiwiki.ai/wiki/google) and [Google DeepMind](https://aiwiki.ai/wiki/google_deepmind). Announced on August 5, 2026, the company is structured as a public benefit corporation whose stated mission is "to automate machine learning, science, and engineering to accelerate discoveries and progress."[1] Its core technical bet is what the founders call "automating the experimental loop": building AI systems that can propose experiments, implement and run them, evaluate the results, and iterate, executing thousands of such loops in parallel across domains such as [machine learning](https://aiwiki.ai/wiki/machine_learning) research, chip design, biology, drug discovery, and materials.[2][3] Dean, who left Google after roughly 27 years, serves as chief executive.[3][4] The initial funding round was announced as led by [Khosla Ventures](https://aiwiki.ai/wiki/khosla_ventures) and [Radical Ventures](https://aiwiki.ai/wiki/radical_ventures), with participation from [Lightspeed](https://aiwiki.ai/wiki/lightspeed_venture_partners), [Kleiner Perkins](https://aiwiki.ai/wiki/kleiner_perkins), Doerr Capital, and Alphabet; Google is a founding investor and will supply cloud computing for the company's first year.[3][4][5][8] The founders declined to disclose how much they raised or at what valuation.[3][4] Business Insider reported in August 2026 that the company had been in discussions for about $1 billion at a valuation of around $10 billion, and on September 11, 2026 that it was raising again at a valuation of around $50 billion; both reports cited people familiar with the matter and said terms could change.[9][10]

## Background

Discovery Loop emerged from one of the most significant leadership departures in the history of Google's AI organization. On August 5, 2026, Google announced changes to [Google DeepMind](https://aiwiki.ai/wiki/google_deepmind) in a blog post from CEO [Sundar Pichai](https://aiwiki.ai/wiki/sundar_pichai): [Demis Hassabis](https://aiwiki.ai/wiki/demis_hassabis) became Chair of Google DeepMind and Chief Scientist of Alphabet while continuing to lead [Isomorphic Labs](https://aiwiki.ai/wiki/isomorphic_labs), [Koray Kavukcuoglu](https://aiwiki.ai/wiki/koray_kavukcuoglu) stepped up as SVP of Google DeepMind reporting to Pichai, and, in Pichai's words, "after an incredible 27-year run, Jeff Dean is at a moment where he wants to try something new."[5] Pichai wrote that Dean and Google Senior Fellow Sanjay Ghemawat were "launching an independent public benefit corporation to accelerate discoveries in ML, science, and engineering," and that Google would "continue to work with them as a founding investor and Cloud partner, and collaborate on a research framework for ML systems and related infrastructure advances."[5]

The same day, Dean announced the company on X: "along with my longtime friends and collaborators @Sanjay_Ghemawat, @OriolVinyalsML and @quocleix, we are founding Discovery Loop (@DiscoLoopAI), a Public Benefit Corporation whose mission is to automate machine learning, science, and engineering to accelerate discoveries and progress." He noted that the four founders had worked together "for 14 to 30 years."[1]

According to Wired's Steven Levy, who interviewed the founders before launch, the idea came together only weeks before the announcement. Dean said the four "were working on different things, but we were all starting to see the possibility of AI being able to automate scientific and engineering loops."[3] The New York Times reported that Dean, 58, planned to leave Google within days of the announcement, and quoted him describing the thesis: "We think there is opportunity for A.I. to more fully automate what has traditionally been a very human-intensive experimental loop. You will get both a higher quantity and a higher quality of experiments, and that will lead to scientific breakthroughs and advances."[4] Business Insider later described Dean as having resigned as Google's chief scientist in August 2026.[10]

Dean had publicly hinted at the concept before the launch. Speaking at [Y Combinator](https://aiwiki.ai/wiki/y_combinator)'s Startup School in San Francisco on July 25, 2026, he described an automated version of the scientific method, "You propose an experiment, you implement what you need to run the experiment, you evaluate the experiment, and then you get results from that," and said running thousands of such automated loops could unlock advances in science, biology, chip design, and AI models themselves; per Wired, the audience did not know he was describing his own secret startup.[3]

Wired reported that negotiating the exit was difficult, with Pichai attempting over multiple meetings to persuade the group to stay, before Google ultimately gave the departures "its blessing, along with an investment and an arrangement to provide compute power for the first year."[3] Vinyals told Wired: "In a large organization there is always a lot of inertia you have to overcome to make any radical changes. We want to build something different."[3] Ghemawat, quoted in a Wall Street Journal report summarized by Yahoo Finance, said "We wanted to build something differently than how things are built at Google right now," noting that Google's infrastructure is tailored to massive consumer applications rather than specialized research systems.[6]

## Approach

Discovery Loop's website describes the company as "automating discovery to accelerate science and engineering for the world," a line that also serves as the bio of its X account.[2][17] The site frames scientific discovery as "bottlenecked" by manual, sequential experimental iteration, and describes the company's goal as building systems that automate entire experimental loops: using frontier AI models and large-scale computational infrastructure to "rapidly propose, run, and learn from evaluations," with thousands of experiments executing in parallel.[2]

The company describes a staged plan:

- **Start with machine learning.** The initial focus is automating machine learning research and engineering itself.[2] Le told Wired: "I'm very excited about automating machine learning. It might be that we will discover a different transformer architecture."[3]
- **Act as its own first customer.** Discovery Loop says it will use its automated ML capabilities to optimize its own technology stack before expanding to other domains.[2] Per Wired, the improved software would then become the core of a system applied to chip design, biology, drug discovery, and material design.[3]
- **Grand Challenges.** The company says its approach can address "any learning loop with measurable outcomes" in science and engineering, and that it ultimately aims to take on National Academy of Engineering (NAE) Grand Challenges such as engineering better medicines, advancing health informatics, making solar energy economical, providing access to clean water, securing cyberspace, and engineering the tools of scientific discovery.[2] In his launch thread Dean wrote that the approach "can help with important subproblems in nearly every one of the fourteen NAE Grand Challenge problems."[8]

The New York Times placed the company within a broader Silicon Valley pursuit of [recursive self-improvement](https://aiwiki.ai/wiki/recursive_self-improvement), AI that improves itself with little or no human help, which the founders believe can accelerate AI development and then generalize to hardware design, drug discovery, and new materials.[4] Vinyals addressed that idea directly at Berkeley RDI's Agentic AI Summit 2026, where he appeared on a panel billed as a co-founder of Discovery Loop.[14] Reporting on the talk, The Decoder's Manuel Uth wrote that Vinyals broke self-improvement into a chain of steps, having a promising idea, writing the code that implements it, running experiments, and judging reliably whether the change helped, and that AI is already making progress on the middle two while idea generation and evaluation are where systems still fall short. On that reading, Vinyals considers a sudden, self-accelerating intelligence explosion unlikely, even though he expects AI to speed up some research and engineering tasks by a factor of ten or more.[13]

Vinyals told Wired that a central research problem is idea generation: "One of the things that we'll be obviously very focused on is how these models come up with new ideas to try. That's not something that currently they're super strong at."[3] The founders initially envision human co-development of experimental ideas, with deeper automation as the goal; Wired reported that small teams using Discovery Loop's systems could become customers, and that the startup may also run its own loops to seek and monetize breakthroughs.[3]

At launch the company had not yet hired a team or rented office space, according to Wired.[3] Dean wrote in his launch thread that the founders' immediate order of business was to find office space and hire a founding team over the following weeks.[8] The company describes itself as building "a lean, in-person team,"[2] and as of September 13, 2026 its Ashby careers board still listed a single opening, a Member of Technical Staff role in Palo Alto, California, first posted on August 4, 2026.[7][11] That listing says the company is hiring "across a range of research and engineering roles, including post-training, agents, infrastructure, environments, data, and evaluations," and states the goal of building "AI that acts as a genuinely positive, empowering force for humanity: not just a tool, but a partner in solving the problems that matter most."[11]

## Founding team

The four founders have worked together for between 14 and 30 years.[1] The company states that they collectively represent three of the most-cited researchers in artificial intelligence and two of the most-cited researchers in distributed systems, and credits them with contributions to multiple generations of Google Search, Google Ads, Google Translate, Google File System, MapReduce, BigTable, Spanner, [TensorFlow](https://aiwiki.ai/wiki/tensorflow), [Pathways](https://aiwiki.ai/wiki/pathways), [TPUs](https://aiwiki.ai/wiki/tpu), [AlphaChip](https://aiwiki.ai/wiki/alphachip), [AlphaStar](https://aiwiki.ai/wiki/alphastar), [AlphaCode](https://aiwiki.ai/wiki/alphacode), [AlphaFold](https://aiwiki.ai/wiki/alphafold), [Gemini](https://aiwiki.ai/wiki/gemini), model [distillation](https://aiwiki.ai/wiki/knowledge_distillation), [mixture-of-experts](https://aiwiki.ai/wiki/mixture_of_experts) architectures, [word2vec](https://aiwiki.ai/wiki/word2vec), sequence-to-sequence models, [chain of thought](https://aiwiki.ai/wiki/chain_of_thought) reasoning, and [neural architecture search](https://aiwiki.ai/wiki/neural_architecture_search).[2]

**[Jeff Dean](https://aiwiki.ai/wiki/jeff_dean)**, Discovery Loop's CEO, joined Google in 1999 as approximately its 30th employee and, per the New York Times, is "widely regarded as one of the most important figures in the history of the company." With Ghemawat he designed foundational distributed systems including MapReduce, BigTable, and Spanner, which became templates for large-scale computing across the industry. He led the creation of [Google Brain](https://aiwiki.ai/wiki/google_brain) in 2011, and served as chief scientist of Google DeepMind and Google Research and as a technical co-lead of the Gemini model effort.[3][4] When Levy asked who would be CEO, Dean answered: "I think I'm the CEO. Everyone pointed at me."[3]

**[Sanjay Ghemawat](https://aiwiki.ai/wiki/sanjay_ghemawat)** was Dean's close collaborator for more than two decades and co-designed Google's core computing and search infrastructure. He and Dean are the only two Google employees to have been named Senior Fellow, the company's highest technical rank.[4][5]

**[Oriol Vinyals](https://aiwiki.ai/wiki/oriol_vinyals)** was VP of Research at Google DeepMind and a technical lead for Gemini; the New York Times reports that he oversaw the design of Google's chatbot technologies alongside Dean beginning in 2023. An early Google Brain hire, he helped develop the language translation technology that became a milestone on the path to modern AI, and is known for work including sequence-to-sequence learning and AlphaStar.[3][4]

**[Quoc Le](https://aiwiki.ai/wiki/quoc_le)** was a co-founder of Google Brain and, per Wired, the key scientist behind AutoML-Zero, a project using machine learning algorithms to autonomously build AI systems; the New York Times writes that his research "helped inspire the creation of today's A.I. chatbots."[3][4] His published work spans areas the company's own list highlights, including [neural architecture search](https://aiwiki.ai/wiki/neural_architecture_search) and chain-of-thought reasoning.[2]

The pitch deck Dean posted on X drew attention for the founders' track record. Business Insider's Thibault Spirlet reported that one slide listed products the team helped build, including Google Search, Ads, Gmail, Gemini, and TPUs; a second named people the founders had managed or worked with who went on to lead other AI companies, including Anthropic cofounder Dario Amodei, OpenAI and [Safe Superintelligence](https://aiwiki.ai/wiki/safe_superintelligence) cofounder Ilya Sutskever, OpenAI cofounder Wojciech Zaremba, Perplexity CEO Aravind Srinivas, and Mistral cofounder Arthur Mensch; and a third showed Google Scholar rankings placing Dean, Le, and Vinyals among the most highly cited AI researchers. Bilawal Sidhu, a former Google product leader, wrote on X that the deck "will go down in history as one of the most stacked pitch decks ever made."[15]

## Funding and structure

Discovery Loop is incorporated as a public benefit corporation, a for-profit structure with a stated public-good purpose that has also been adopted by [Anthropic](https://aiwiki.ai/wiki/anthropic), [OpenAI](https://aiwiki.ai/wiki/openai), and other AI companies.[4] Dean told the New York Times: "There is a lot of good that can be done in the world if we can distribute scientific discoveries broadly."[4] Business Insider reported that Dean said at a talk the previous month that he and his cofounders "might make decisions that are not in the company's financial interest but are in the broader societal good."[10]

In the launch thread that Radical Ventures republished on August 9, 2026, Dean wrote: "We are delighted to have selected Radical Ventures and Khosla Ventures to lead our initial funding round, along with participation from Lightspeed, Kleiner Perkins, Doerr Capital (John Doerr), and Alphabet (Google). We'll be working with them to close our seed round over the next few weeks."[8] Radical Ventures described its own position in the round as a co-lead.[8] Yahoo Finance, summarizing the Wall Street Journal, likewise described Khosla Ventures and Radical Ventures as co-leads, and Wired referred to "a handful of other firms" alongside Google as a founding investor.[3][5][6] The founders declined to disclose the amount raised or the valuation.[3][4] Radical Ventures managing partner Jordan Jacobs joined the board.[3] Alphabet also agreed to provide the computing power for the startup's AI work for at least its first year, and Pichai said Google would collaborate with the company on a research framework for ML systems and related infrastructure.[4][5]

Vinod Khosla, who met the founders at his Sand Hill Road office on a Saturday to preserve secrecy, told Wired: "With this team, I wouldn't need to know what they were doing before I backed them. It's the ultimate superstar team," adding, "Humans have been using AI to do research, not using AI to be a researcher. The fundamental thing [in Discovery Loop] is that AI is the researcher."[3] In a post quoted by Business Insider, Khosla compared the company to his early investment in OpenAI and wrote: "This team can redefine how research in engineering and science is done. If successful, the impact won't be measured in software features, or benchmarks but in new science to improve billions of lives."[10]

## Reported funding talks

Both of the dollar figures reported for Discovery Loop's fundraising come from Business Insider, which attributed each of them to people familiar with the matter.

On August 13, 2026, Business Insider's Katie Roof and Ben Bergman reported that Dean "has been in discussions for $1 billion in financing at a valuation of around $10 billion" for Discovery Loop. The article said "details of the round could change" and that a representative for Dean declined to comment. It also cited a Discovery Loop press release dated August 5 as the source for the investor list: the round led by Radical Ventures and Khosla Ventures with participation from Lightspeed, Kleiner Perkins, and Doerr Capital.[9]

On September 11, 2026, Business Insider's Ben Bergman reported that Dean "is raising again for his new AI startup, Discovery Loop, this time seeking a valuation of around $50 billion." The article noted that "terms of the deal could change, and there is no guarantee Discovery Loop will be able to raise a round of funding at that valuation," that a Discovery Loop spokesperson declined to comment, and that Dean did not respond to a request for comment.[10] Bergman placed the jump in the context of other research-heavy labs that raised large sums before shipping products, writing that "other new AI labs, such as Safe Superintelligence and [Thinking Machines Lab](https://aiwiki.ai/wiki/thinking_machines_lab), have raised staggering sums at eyepopping valuations before they had products," something he said would have seemed inconceivable in earlier fundraising cycles but now "reflects investors' conviction that a small number of elite technical teams could become the next generation of frontier AI companies."[10]

Discovery Loop has not itself confirmed either report. As of September 13, 2026 the Discovery Loop website carried no funding announcement, and the company's X account, @DiscoLoopAI, had posted once since it was created in July 2026.[2][17] A search of the US Securities and Exchange Commission's EDGAR full-text search and company database on the same date returned no Form D or other filing under the Discovery Loop name.[16]

## Reception and context

Coverage of the launch centered on what the departures mean for Google. Wired's Steven Levy called the exit "a devastating blow" to Google even with its investment in the company, likening Dean and Ghemawat leaving to "Mick Jagger and Keith Richards ditching the Rolling Stones to start a new band," and framed the startup's bar for success with a question: "Will the work they do as a startup be as significant as the talent gap they're creating by leaving Google?"[3] Alphabet shares fell as much as 5.4 percent to a session low on the day of the announcement, according to Yahoo Finance.[6]

The New York Times' Cade Metz wrote that the move "exposes the changing power structure inside Google and shows there is still plenty of venture money willing to back new A.I. ideas," and placed it in a string of research departures from Google over the prior year, including former research head Peter Norvig's move to the startup Recursive Superintelligence and Gemini co-lead Noam Shazeer's departure for OpenAI less than two months earlier.[4] Metz also noted that Discovery Loop joins a growing list of prominent startups chasing a goal that has obsessed Silicon Valley researchers for decades, with the startup betting that its founders' track record will let it deliver working systems.[4] Levy made the same point, writing that "just about every major figure in AI" has claimed AI will solve problems humans cannot crack alone, and that this team is wagering its knowledge and skills will prevail in actually building such a system.[3]

Reuters reported on August 12, 2026 that Dean and Vinyals, Gemini's original technical co-leads, had left as part of the shakeup, and that staff reporting to some of the departing leaders "had held a rare degree of agency to conduct research not directly related to training Gemini," according to three sources. In the wake of the departures, Reuters wrote, Google did not immediately share plans for the fate of those teams or projects, "making some anxious that the lab's bulwark against commercial interests would further erode."[12]

Business Insider situated Discovery Loop in a run of Google alumni raising large sums for new research labs, naming [Ineffable Intelligence](https://aiwiki.ai/wiki/ineffable_intelligence), founded by former DeepMind researcher David Silver, [Reflection AI](https://aiwiki.ai/wiki/reflection_ai), founded by former DeepMind researchers Misha Laskin and Ioannis Antonoglou, [Periodic Labs](https://aiwiki.ai/wiki/periodic_labs), and [Sakana AI](https://aiwiki.ai/wiki/sakana_ai).[9]
