Is Demis Hassabis still CEO of Google DeepMind?

Google's August 5, 2026 announcement does not say that he is, and does not say that he is not. It says Hassabis will become Chair of GDM and Chief Scientist of Alphabet while continuing to lead Isomorphic Labs, and that Koray Kavukcuoglu will step up as SVP of Google DeepMind, reporting to Sundar Pichai. No sentence in the announcement retires the CEO title or appoints a new holder of it. As of August 11, the About page at deepmind.google still signs its pull quote Co-founder and CEO, Google DeepMind.

Did Jeff Dean leave Google?

Google's announcement never uses leaving, depart, resign, last day or step down, and gives no final date, so no document establishes whether or when he stops being a Google employee. What Pichai's letter says is that Dean wants to try something new after a tenure it puts at 27 years, and that Dean and Sanjay Ghemawat are launching an independent public benefit corporation. Dean confirmed the company, Discovery Loop, on his own verified account the same day.

What is Discovery Loop building, and who founded it?

Wilson Sonsini, the company's counsel, identifies Discovery Loop, Inc. as a Delaware public benefit corporation founded by Jeff Dean, Sanjay Ghemawat, Quoc Le and Oriol Vinyals. The company's site says it is building systems to automate entire experimental loops with frontier models and large-scale compute, starting with machine learning research and engineering, and using those capabilities on its own technology stack first. The site assigns no job titles, including whether Dean is chief executive.

Did Google invest in Discovery Loop, and how much?

Two documents word it differently and both are on the record. Google's own announcement says it will continue working with the founders as a founding investor and Cloud partner. Wilson Sonsini says the initial round is being co-led by Radical Ventures and Khosla Ventures, with Alphabet among the participants. No amount, valuation or Alphabet contribution has been disclosed by any of the four parties, the round has not closed, and Alphabet has not filed an 8-K about it.

Google Named DeepMind's Next Leader SVP, Not CEO

On August 5, 2026, Google said Demis Hassabis will become Chair of GDM and Chief Scientist of Alphabet. The announcement named no new DeepMind CEO, and never named Discovery Loop.

Discovery Loop’s own homepage, as of August 11, does not say that Discovery Loop is a public benefit corporation.

The page contains no instance of public benefit, PBC, corporation, Delaware, investor, funding or Alphabet. Google appears five times, all of them inside a list of what the founders built before: Google Search, Google Ads, Google News, Google Translate, Google File System. The founding-team section names four people and gives none of them a title.

Whether Jeff Dean is the chief executive is not stated on the site at all.

The document that fills in those blanks is a client-highlights post from a law firm. Wilson Sonsini published it on August 5, the day of the launch, and it carries the full roster: “Jeff Dean, Sanjay Ghemawat, Quoc Le, and Oriol Vinyals (alphabetical)”. The same page identifies the company as Discovery Loop, Inc., a Delaware public benefit corporation, and lists the investors. That parenthetical belongs to the firm, which marks the order as alphabetical rather than ranked.

Google’s announcement, published in the same hour, has a gap of its own: the name Discovery Loop never appears in it.

The post at blog.google, titled The next chapter of our AI momentum, carries two letters to employees, one from Sundar Pichai and one from Demis Hassabis. Across the body, Discovery Loop occurs zero times, and so does Loop. The name reached the public through Dean’s own account, six minutes after the blog post went live.

Google DeepMind’s personnel moves had already drawn coverage in late July, which this site examined in The Counter Was Still Running.

Google’s letter names two founders; the law firm names four

Pichai’s letter spends two sentences on the new company. The first puts Dean’s tenure at 27 years and says he wants to try something new, with Google glad to support him. The second says Dean and Google Senior Fellow Sanjay Ghemawat are launching an independent public benefit corporation to accelerate discoveries in ML, science and engineering.

Ghemawat’s title in that sentence is a Google title, not a Google DeepMind one.

Vinyals and Le are absent from the letter, where Vinyals, Oriol and Quoc each occur zero times. The four-name roster came from the founders themselves, in a burst of posts that ran from the Discovery Loop account at 16:00 UTC through Pichai at 16:01, Ghemawat at 16:02, Hassabis at 16:04, Vinyals at 16:05, Dean at 16:06 and Le at 16:07. Vinyals’s post dates his arrival at Google to 13 years earlier, traces a path from Brain to DeepMind to Google DeepMind, and names Google DeepMind as the team he is leaving.

Eight minutes, start to finish.

First-day coverage inherited the gap, with CNBC and The Verge naming only Ghemawat alongside Dean. The Verge’s August 6 follow-up widened that to three top AI researchers going with him.

Parts of the setup predate the announcement: the verified @DiscoLoopAI account was created in July 2026 and had posted once. The company’s Ashby careers page went live on August 4 at 16:50 UTC with one opening, Member of Technical Staff in Palo Alto, onsite, roughly 23 hours before the public launch.

The letter hands day-to-day GDM leadership to an SVP

Pichai’s wording on Hassabis is a single clause: “Demis will become the Chair of GDM and Chief Scientist of Alphabet,” while continuing to lead Isomorphic Labs. Chair, not chairman, and Chairman occurs zero times in the letters.

Hassabis gives his own reason, writing that the moment was right to “hand over my day-to-day operational responsibilities at GDM,” freeing time and space for the big picture. Pichai’s letter adds that Hassabis has described the company as standing in the foothills of the singularity, and has been spending a lot of his time engaging externally.

Koray Kavukcuoglu, GDM’s chief technology officer and Google’s Chief AI Architect, “will step up as SVP of Google DeepMind, reporting to me.” His remit covers Gemini model development, Frontier AI research, and the Gemini app and developer teams. Pichai’s letter puts him at DeepMind for 13 years, starting its deep learning team and leading work on WaveNet and DQN.

SVP is not CEO.

In the body of the announcement, CEO refers only to Pichai. No sentence says Hassabis is stepping down as chief executive, and no sentence appoints a new one at Google DeepMind. What the announcement fixes is the reporting line, and the fate of the title goes unaddressed.

As of August 11, two Google pages disagree with each other on the title. The byline on the blog post already reads Chair, Google DeepMind and Chief Scientist, Alphabet, while the About page at deepmind.google, on the same date, still signs its pull quote Co-founder and CEO, Google DeepMind, and still describes the merged Brain and DeepMind team as one led by Hassabis as CEO.

Every verb about the transition points forward: effective occurs zero times, the letters say will become and will step up, and no start date appears anywhere.

Outlets did not agree on Dean’s outgoing title either. CNBC called him Google chief scientist, while The Verge called him the chief scientist of Google DeepMind and Google’s 30th employee, and those describe two different levels. Chief Scientist of Alphabet is the new title, and it goes to Hassabis.

No document in the chain carries a dollar figure

Google describes its own position in one clause, saying it will keep working with the founders “as a founding investor and Cloud partner,” and collaborate on a research framework for ML systems and related infrastructure advances.

Wilson Sonsini describes the round differently, writing that the initial funding round is being co-led by Radical Ventures and Khosla Ventures, with participation from Lightspeed, Kleiner Perkins, Doerr Capital and Alphabet.

Both wordings can hold at once, because a founding investor can also sit in the participant list for a round; the two documents chose different emphases, and neither of them gives an amount.

Compute has two versions as well, since Wilson Sonsini writes that Discovery Loop has established “a long-term partnership with Alphabet for cloud and compute resources,” while WIRED describes an arrangement “to provide compute power for the first year.” The time frames differ, and the available sources do not settle whether the two describe the same thing.

Money is a consistent blank. The law firm’s page carries no figure and no instance of valuation, seed or first year, WIRED reported that the founders would not disclose the amount or the valuation, and Quartz wrote that the round had not closed and the startup would not give a valuation. Google’s letter names no sum, and Discovery Loop’s site does not mention funding.

Discovery Loop’s stated first target is machine learning research itself

The site’s problem statement opens on the scientific method and praises it, then puts the bottleneck in execution: repetitive experimental loops that are hard to scale by hand, where you propose an experiment, implement and run it, examine the results, and iterate.

Placement matters here, because the scientific method is the thing being admired rather than the thing being replaced. What the company says it is building is systems to “automate these entire experimental loops,” using frontier models and large-scale compute to propose, run and learn from evaluations quickly.

Two of the site’s three sub-headings narrow it further. The first says the initial focus is automating the process of machine learning research and engineering. The second reads Act as Our Own First Customer, meaning the automated ML capabilities go into the company’s own technology stack before anything else.

The rest is thin by design, since the site calls the team lean and in-person, gives no headcount, and lists a single advertised job, in Palo Alto.

Dean’s own post states the mission more broadly than the site’s first phase, describing it as automating machine learning, science and engineering to accelerate discoveries and progress.

Recursive self-improvement is a reporters’ frame rather than the company’s. TechCrunch’s writer added it as a gloss, “a process known as recursive self-improvement,” and Axios used it in the negative, writing that the industry has yet to achieve it. Neither attributes the phrase to a founder, and recursive occurs zero times in the announcement, on the site and in the job posting.

In 2025 documents, OpenAI and Anthropic placed their science programs inside the company

OpenAI’s program carries a name. A December 2025 post situates the work inside OpenAI for Science, calls it the company’s own effort, and gives it a VP-level lead, Kevin Weil, Vice President of OpenAI for Science. Anthropic launched its AI for Science program in May 2025, offering API credits to researchers, and has written that increasing the rate of scientific progress is a core part of its public benefit mission.

The comparison only reaches so far, because both of those point AI at science while Discovery Loop’s stated first phase points it at machine learning research and engineering, the work that produces the models. With the missions unalike, organizational position is the only clean axis left.

Public benefit status is not the difference, given that OpenAI’s for-profit arm became OpenAI Group PBC in October 2025 and Anthropic is itself a public benefit corporation.

What differs is location.

Discovery Loop is a separate legal entity, formed in 2026, and Google did not relocate an existing internal group to create it. Four founders set up a new company, and Google’s role is investor and cloud partner. Where OpenAI for Science stands has no official answer, because third-party reports say the team was broken up or absorbed around April 2026, while openai.com carries no statement either way and, as of August 11, the science page is still live. The description that can be sourced is the one from launch.

No document gives an effective date, a dollar figure, or a job title

Time comes first: effective occurs zero times in the announcement, and so do leaving, depart, resign, last day and step down. Dean has no published last day at Google, the only fixed date is the announcement itself on August 5, 2026, and who picks up his responsibilities, or whether the role stays, goes unaddressed.

Then the money: no amount comes from Google, from the company, from the law firm or from the investors, the round has not closed, and Alphabet has not filed an 8-K about it. A full-text search of SEC EDGAR limited to July 1 through August 11, 2026 returns no filings mentioning Discovery Loop, while an unrestricted search returns seven, none of them connected to the company. Valuation figures circulating online come from prediction-market estimates.

Then the titles: the site gives no one a title, Dean included, and what Ghemawat, Vinyals and Le will do at Discovery Loop is stated by no source.

One gap sits underneath the other three. Google has never acknowledged that Vinyals and Le left, and the two men’s own words carry unequal weight: Vinyals wrote “I’m saying goodbye to GDM,” while Le’s post confirms the co-founding and mentions no departure. For both of them, the public record is their own posts and a company website that hands out no titles.
