LONDON — Wherever Nvidia CEO Jensen Huang goes, excitement follows — this time, all the way to London Tech Week.

The Nvidia boss — whom Wedbush analyst Daniel Ives dubs the “godfather of AI” — is more like a rockstar these days, given his wide-spanning effect on the AI industry.

“The amount of infrastructure required for AI wouldn’t be possible without that man,” one attendee at London Tech Week said.

“He’s like Iron Man,” the attendee added, referencing the popular Marvel superhero who is a tech billionaire inventor under the name of Tony Stark.

The lines to get into the Olympia auditorium were already building around 40 minutes before Jensen was set to take the stage alongside U.K. Prime Minister Keir Starmer. Not everyone managed to get in — but there were helpfully screens around the venue where people could catch a glimpse of Huang’s talk.

The Nvidia CEO gave his continued bullish assessment of artificial intelligence, calling it an “incredible technology” and saying it should be seen as infrastructure, just like electricity. 

UK gets glowing endorsement from Huang 

There weren’t any multi-billion dollar investments touted at London Tech Week. But the biggest win for Starmer and the U.K. by far was Huang’s lavish praise for the country.

Wearing his trademark leather jacket, Huang called the U.K. the “envy of the world” that is in the midst of a “Goldilocks circumstance,” boasting a vibrant venture capital ecosystem, as well as budding AI entrepreneurs from leading firms including Google DeepMind, Synthesia, Wayve and ElevenLabs.

Speaking alongside Huang, Starmer spoke in an animated manner as he touted Nvidia’s investments in the U.K. Earlier in the day, the U.S. chipmaker announced a new “U.K. sovereign AI industry forum,” as well as commitments from cloud vendors Nscale and Nebius to deploy new facilities containing thousands of its Blackwell GPU chips.

Starmer spoke at length about AI’s promise and the ways in which it could ease the burdens faced by the U.K.’s public sector institutions, from hospitals to schools.

Huang added that the U.K. is “such a great place to invest,” noting that Nvidia plans to partner with the country to upskill tech workers and build out domestic AI infrastructure.

“Infrastructure enables more research — more research, more breakthroughs, more companies,” the Nvidia chief said. “That flywheel will start taking off. It’s already quite large, but we’re just going to get that flywheel going.”

Starmer thanked Huang for his point, commenting that “the confidence it gives when you explain it that way is huge.”

“From our point of view, we’re really pleased to be seen that way,” the U.K. leader said.

The pair shook hands at the end.

Altogether, there was a lot of energy in the room. Huang said he was “excited” for London Tech Week, and he was met with a round of applause from the audience.

Alphabet’s Verily covered up HIPAA violations, whistleblower says in lawsuit

Alphabet's Verily covered up HIPAA violations, whistleblower says in lawsuit

Alphabet’s health tech subsidiary Verily used the health data of more than 25,000 patients without authorization and actively covered up those violations, a former company executive alleges. 

The executive, Ryan Sloan, claims Verily fired him after he discovered breaches of the Health Insurance Portability and Accountability Act, or HIPAA, and reported his concerns to the company’s senior management.

Patient data in the U.S. is protected under HIPAA, which ensures the sensitive information cannot be disclosed without a patient’s consent.

Sloan’s allegations are detailed in a pending lawsuit in federal court in San Francisco. The suit, which was filed late last year, has not been previously reported.

On Monday, the judge overseeing Sloan’s case denied a request by Verily to dismiss his civil complaint, or to send the dispute to arbitration.

Verily believes the allegations and contentions alleged in this employment matter that was commenced in 2023 are completely without merit. Verily will defend itself to the full extent of the law,” a company spokesperson told CNBC in a statement. “Verily is an equal opportunity employer, and takes its responsibility and commitment to abide by all laws and regulations seriously.  As this is an ongoing legal matter, Verily will not be providing further comment at this time.”

Representatives for Sloan did not comment.

Verily started as a moonshot in 2015 within Alphabet’s innovation lab X, formerly known as Google X. It’s Google’s sister company and operates under Alphabet’s “Other Bets” category.

The company hired Sloan in 2020 to serve as the chief commercial officer of its diabetes and hypertension business, Verily Onduo.

In January 2022, Sloan alleged that he and Julia Feldman, Onduo’s general counsel, discovered Verily had improperly used patients’ protected health information in its research, marketing campaigns, press releases and national conferences. The “extensive violations” affected more than 25,000 patients in Onduo’s diabetes program, according to an amended complaint filed in June. 

Sloan and Feldman informed senior Verily leaders of their findings, the filing said, and they repeatedly raised the issue. An internal investigation at Verily confirmed several HIPAA breaches took place, according to the filing.

“Between January and March of 2022, internal investigators at Verily confirmed multiple breaches of fourteen (14) separate HIPAA Business Associate Agreements with large, covered entity clients of Onduo between 2017 and 2021,” the filing said.

Patients who accessed Verily Onduo through these clients – which include Walgreens Boots Alliance, Highmark Health, Quest Diagnostics and Delta Air Lines, among others – may have been affected by the breaches. 

Delta said in a statement that it doesn’t have a comment on the suit, “but our employee’s personal information is important to us.”

“We are looking into this and will make sure any impact to our people is appropriately addressed,” the company said.

Quest said in a statement that, “We are not familiar with the allegations and have no further comment.”

Highmark declined to comment. Walgreens did not respond to CNBC’s requests for comment.

Under HIPAA, companies like Verily are supposed to notify impacted parties no later than 60 days after discovering a breach. Verily “decided to delay the decision of notifying the covered entities,” according to the filing, and the company engaged in negotiations to renew many of those contracts “without revealing that a HIPAA breach had recently occurred.” 

“During a contract negotiation between Verily and Highmark Health in August of 2022, Verily represented that it was in compliance with HIPAA at all times, while knowingly concealing that a HIPAA breach had occurred,” the filing said. 

That same month, Verily terminated Feldman and another employee who was aware of the breaches.

When Sloan reiterated his concerns about the breaches to Lisa Greenbaum, Verily’s then chief revenue officer, in October 2022, she allegedly defended the company’s decision not to disclose them and said that doing so would negatively affect public relations, the filing said.

Greenbaum joined Doximity, another health-care technology company, as chief commercial officer in January 2024, according to her LinkedIn. 

Doximity did not immediately respond to request for comment.

In November 2022, Verily allegedly suppressed a press release out of concern that it would draw attention to previous marketing studies that violated its HIPAA Business Associate Agreements. The company removed the press release from its website and instructed employees not to mention it again, according to the filing. 

Sloan was officially terminated from Verily in January of 2023, while on protected leave to care for his “critically ill mother,” the filing said. 

The lawsuit marks the latest in a series of stumbles at Verily, which, despite raising more than $1 billion from investors, has struggled to latch onto a winning product. Verily is reportedly transitioning from a Limited Liability Company, or an LLC, to an investor-friendly C-corp structure to prepare for a fresh round of funding, according to a report from Business Insider on Wednesday.

Verily originally developed hardware like continuous glucose monitors before pivoting to pandemic response when Covid-19 broke out in 2020, then switched directions again to focus on precision health in 2022. 

The company introduced a new artificial intelligence-powered chronic care solution called Verily Lightpath last year, and announced it was selling its stop-loss insurance subsidiary, Granular Insurance Company, in February.

Opendoor stock soars 60% after company names new CEO

OpenDoor is disrupting the real estate market with its new model. It buys homes and sells them on its platform.

Opendoor

Opendoor stock rocketed 60% higher on Thursday after the retail favorite named Shopify executive Kaz Nejatian as CEO and co-founder Keith Rabois as chairman.

The meme stock hit a 52-week high and continued a stunning run this year, with shares up more than 400% so far.

Former CEO Carrie Wheeler resigned last month following a pressure campaign from investors that included critical comments from Rabois and hedge fund manager Eric Jackson, who has been a key part of the stock’s resurgence this year.

Jackson built a massive following on X in part thanks to his successful bet on Carvana, and then turned his attention to cheering a turnaround at Opendoor.

Opendoor said Wednesday it was “going into founder mode” by bringing Rabois and Eric Wu, who served as the company’s first CEO before stepping down in 2023, back to the board.

The company went public through a special purpose acquisition company in 2020. Opendoor’s business involves using technology to buy and sell homes, pocketing the gains.

Nejatian said the company will use artificial intelligence to make the process of buying and selling a home “radically simpler, faster and more certain.”

Shares of Opendoor traded below $1 earlier this year, and the company was in danger of being delisted from the Nasdaq.

Opendoor taps new CEO and names Keith Rabois chairman, boosting stock 30%

Opendoor, the online real estate platform that’s seen a surge of retail investor interest in recent months, said Wednesday that it’s tapped former Shopify executive Kaz Nejatian as CEO and named co-founder Keith Rabois as chairman.

The stock popped 30% in extended trading, and is now up more than fifteenfold since hitting its record low in June.

Rabois, a partner at Khosla Ventures, helped launch Opendoor in 2014, along with a group that included Eric Wu, who served as the first CEO before stepping down in 2023. Wu is rejoining the board as part of Wednesday’s announcement.

The moves come after Carrie Wheeler last month resigned as Opendoor’s CEO following an intense pressure campaign from investors. Rabois and hedge fund manager Eric Jackson were among those who were vocal critics of Wheeler and called for her departure.

The company was at risk of being delisted from the Nasdaq in May due to its stock price being below $1. Weeks later, Opendoor attracted a surge in interest from retail investors, earning it “meme stock” status, after Jackson began touting the company.

With the after-hours pop, Opendoor now has a market cap of close to $6 billion, up from less than $400 million less than three months ago.

Nejatian spent six years at Shopify and oversaw the Canadian e-commerce company’s product division in addition to serving as its COO. Nejatian’s last day at Shopify will be Sept. 12, and the company’s executive team will “assume Kaz’s responsibilities,” Shopify said in a regulatory filing.

“Literally there was only one choice for the job: Kaz,” Rabois said in a statement. “I am thrilled that he will be serving as CEO of Opendoor.”

Opendoor went public through a special purpose acquisition company in 2020. The company’s business involves using technology to buy and sell homes, pocketing the gains.
