Epic Systems, the largest provider of software for managing medical records, says a venture-backed startup called Particle Health is using patient data in unauthorized and unethical ways that have nothing to do with treatment.
Epic told customers in a notice on Thursday that it cut off its connection to Particle, hindering the company’s ability to tap a system with more than 300 million patient records. Particle is one of several companies that acts as a sort of middleman between Epic and the organizations — typically hospitals and clinics — that need the data.
Patient data is inherently sensitive and valuable, and it’s protected by the Health Insurance Portability and Accountability Act, or HIPAA, a federal law that requires a patient’s consent or knowledge for third-party access. One way Epic’s electronic health records (EHR) are accessed is through an interoperability network called Carequality, which facilitates the exchange of more than 400,000 documents a month, according to its website. Particle is a member of the Carequality network.
To join the network, organizations are vetted and have to agree to abide by clear “Permitted Purposes” for the exchange of patient data. Epic responds to requests for data that fall under the “Treatment” permitted purpose, which means the recipient is providing care to the person whose records they are requesting.
Epic said in its notice on Thursday that it filed a formal dispute with Carequality on March 21, over concerns that Particle and its participant organizations “might be inaccurately representing the purpose associated with their record retrievals.” The company suspended its connection with Particle that day.
“This poses potential security and privacy risks, including the potential for HIPAA Privacy Rule violations,” Epic said in the notice, which was obtained by CNBC.
In a blog post late Friday, Carequality said it takes disputes “very seriously and is committed to maintaining the integrity of the dispute resolution process as well as trusted exchange within the framework.” The organization said it can’t comment about the existence of any disputes or member activities.
Representatives from Epic and Particle didn’t respond to requests for comment. However, Particle published a blog post Friday evening and said it began “addressing this issue immediately” after Epic “stopped responding to data requests from a subset of customers” on March 21. Particle said in the post that a big challenge in such matters is that there is “no standard reference to assess the definition of Treatment.”
“These definitions have become more difficult to delineate as care becomes more complicated with providers, payers, and payviders all merging in various large healthcare conglomerates,” Particle wrote.
Epic, a 45-year-old privately held company based in Wisconsin, isthe largest EHR vendor by hospital market share in the U.S., with 36% of the market, according to a May report from KLAS Research. Oracle is second at 25%, following the software company’s $28 billion purchase of Cerner in 2022.
As of July 2022, Particle had raised a total of $39.3 million from investors including Menlo Ventures, Story Ventures and Pruven Capital, according to a release. The New York-based startup said at the time that its technology “uniquely combines data from 270 million plus patients’ medical records by aggregating and unifying healthcare records from thousands of sources.”
Epic said Particle introduced thousands of new participant connections to Carequality in October, and asserted that they fell under the treatment use case. In the following months, all of Particle’s participant organizations claimed a permitted purpose of treatment for their requests, Epic said.
‘Non-treatment use case’
However, Epic began to notice some red flags. The company said it observed anomalies in the patient record exchange patterns, like requests for large numbers of records within a certain geographical region. Additionally, Epic said that the companies connected to Particle weren’t sending new data back from patients, which “suggests a non-treatment use case.”
Epic and its Care Everywhere Governing Council, consisting of 15 industry representatives, evaluated Particle’s new participant connections and determined that organizations like Integritort, MDPortals and Reveleer, which acquired MDPortals last year, “likely didn’t conform to a Treatment Permitted Purpose,” the notice said.
Epic said it learned that another Carequality member was planning to file a dispute, alleging that Integritort was using the patient data to try and identify potential class action lawsuit participants. On March 28, Epic said it discovered that a participant called Novellia claimed it was requesting records under treatment, despite publicly advertising its product as a “personal health tool.”
Integritort, Reveleer and Novellia didn’t respond to requests for comment.
Epic said it filed a formal dispute with Carequality at the Governing Council’s recommendation. On April 4, Epic asked Particle to provide additional information to illustrate how its participants qualify for the treatment use case, according to the notice.
Michael Marchant, director of interoperability and innovation at University of California Davis Health, serves as the chair of Epic’s Governing Council. He said it’s hard to know exactly why Particle might have provided these organizations with records, or whether it intentionally engaged in wrongdoing. But, he said, companies have to act responsibly even if pressured to deliver financial results.
“If they were selling to things that they knew were not treatment-related organizations in an effort to match VC funding or profit margins or revenue targets or what have you, then that would be really bad,” Marchant told CNBC in an interview.
In a statement on LinkedIn Wednesday, Particle founder Troy Bannister said Epic acted unilaterally, and that Particle has not seen “rationale, justification or official claims” surrounding these issues.
Bannister wrote that, to the company’s knowledge, “all of the affected partners directly support treatment.” He said these organizations pull data for care providers and share data back with the Carequality network.
“While we continue maintaining our connection with Carequality, the ability for one implementor to decide, without evidence or even so much as a warning, to disconnect providers at massive scale, jeopardizes clinical operations for hundreds of thousands of patients as well as the trust that is so critical to a trust-based exchange,” Bannister wrote.
Bannister didn’t address Epic’s April 4 request for additional information.
The formal dispute process is still ongoing. Marchant, who also serves as the co-chair of an advisory council at Carequality, said it’s the first time in the network’s history that a complaint has gotten this far.
At the Meta Connect developer conference, Mark Zuckerberg, head of the Facebook group Meta, shows the prototype of computer glasses that can display digital objects in transparent lenses.

Mark Zuckerberg on Wednesday unveiled the $799 Meta Ray-Ban Display glasses, the social media company’s first consumer-ready smart glasses with a built-in display.
The glasses, which costs $799, contain a small digital display that can be controlled via hand gestures through a wristband powered by neural technology, confirming a CNBC report in August. A promotional video of the new smart glasses appeared on Meta’s YouTube page on Monday but was later removed.
Tune in Thursday at 11:00 a.m. ET: Meta Chief Product Officer Chris Cox joins CNBC TV to discuss with Julia Boorstin the highlights of Meta’s annual Connect event, live from the company’s HQ in Menlo Park CA.
The new smart glasses are a bridge between the company’s audio-only Ray-Ban Meta smart glasses and the experimental Orion augmented reality glasses that the company revealed at last year’s Connect event. Orion can overlay 3D visuals over a person’s real-world field of view with the help of a wireless computing puck, but the glasses are expensive to make and not yet available to consumers.
The Meta Ray-Ban Display glasses come with the Meta Neural Band, an EMG wristband that allows users to control the device using hand gestures.
“These are glasses with the classic style that you’d expect from Ray-Ban, but they’re the first AI glasses with a high resolution display and a fully weighted Meta neural band,” Zuckerberg said.
With the new glasses, people can do tasks like watch videos through the display or see and respond to text messages, Zuckerberg said. The display doesn’t block a person’s view, and it disappears when not being used, he said.
The glasses go on sale in the U.S. on Sept. 30.
During a demo, Zuckerberg repeatedly attempted to call Meta tech chief Andrew Bosworth unsuccessfully.
“This is uh — you know, it happens,” Zuckerberg said.
Meta has been developing its smart glasses with eyewear giant EssilorLuxottica since 2019, and last year renewed a long-term partnership agreement to continue making the products.
The company on Wednesday also debuted the Oakley Meta Vanguard smart glasses, intended for athletes who participate in high-intensity sports like snowboarding and mountain biking. The Oakley-branded glasses will cost $499 when they launch on Oct. 21, making it $100 more expensive than the Oakley Meta HSTN glasses that went on sale in June.
The Oakley Meta Vanguard smart glasses have a sportier look than the Oakley Meta HSTN glasses thanks to a wraparound design that extends its colorful lenses around a person’s temples. Unlike the Oakley Meta HSTN glasses, the new model contains a button on the underside of its frames so that athletes who wear helmets can more easily capture photos and videos.
The new sports-centric smart glasses have up to nine hours of battery life, can capture 3K video and contain speakers that are louder than their predecessors. The glasses can connect with Garmin-branded fitness watches to track certain stats like their heart rates using the Meta AI assistant. Preorders start today.
Meta also debuted the Ray-Ban Meta (Gen 2), the latest version of the company’s original smart glasses. The Ray-Ban Meta (Gen 2) costs $379, up from $299 for the version released in 2023. The Ray-Ban Meta (Gen 2) has double the battery life of the previous model, lasting 8 hours on a single charge, and a more powerful camera that can capture 3K Ultra HD video. The new glasses go on sale today.
Zuckerberg also announced Horizon TV, pitching it as a way to watch television shows, sporting events and movies using the company’s Quest VR headsets. Some of Meta’s partners who will be contributing content to the app include Disney and Universal Pictures, Zuckerberg said.

Cybersecurity company Netskope is eying a $7.3 billion valuation after pricing shares at $19 for its upcoming IPO, at the top end of its expected range.
Netskope will start trading on Thursday on the Nasdaq under the ticker symbol “NTSK.” The share sale raised $908.2 million.
Earlier this week, Netskope lifted its expected pricing range to between $17 and $19 a share, up from an original range of $15 to $17. The company revealed plans to go public last month.
Netskope’s offering comes amid a hot period for IPO activity after a years-long lull spurred by step inflation and soaring interest rates. The long-overdue resurgence has fueled optimism on Wall Street and in a venture capital industry eager for return on investment.
Ticket reseller StubHub slid 6% it its first day of trading Wednesday, but a lackluster start may not be reason for concern. CoreWeave went public in March and closed flat in its first day, with shares going on to triple.
Swedish buy now, pay later firm Klarna jumped 15% in its debut this month. Peter Thiel-backed cryptocurrency exchangeBullish, design software company Figma and stablecoin issuer Circle have also jumped since their recent market debuts.

The cybersecurity sector is also undergoing a busy stretch for dealmaking fueled by ongoing artificial intelligence advancements and a shifting threat landscape.
Santa Clara, California-based Netskope was founded in 2012 and is led by co-founder and CEO Sanjay Beri. At the end of July, the company said it had 2,910 employees and 4,317 customers across 90 countries.
Annual recurring revenues rose 33% to $707 million at the end of July and revenues reached $328 million for the six months ended July 31. The company also reported a net loss of $170 million during that period.
Some of Netskope’s significant backers include Accel, Iconiq and Lightspeed Venture Partners.

Two years ago, Nscale was a brand new startup in the U.K. that had yet to raise any outside funding or officially announce its existence.
Last year the London-based company came out of stealth, and in December announced that it had raised its Series A fundraising, totaling $155 million.
Now, Nscale finds itself at the center of the action in the hottest market on the planet: artificial intelligence. And it has close to $700 million in fresh capital from Nvidia, the world’s most valuable company.
In press releases on Tuesday, Nscale was named as an AI infrastructure partner for Nvidia, Microsoft and OpenAI, as the companies expand their buildouts in the U.K. Nscale then said it signed a five-year $6.2 billion agreement with Microsoft and Aker to develop “hyperscale AI infrastructure” in Europe, specifically Norway, where Aker is headquartered.
OpenAI made prior headlines with Nscale, announcing plans in July for a data center in Norway for a Stargate-branded AI data center. Nscale agreed to commit $1 billion for the project, with the goal of racking up 100,000 Nvidia graphics processing units (GPUs) at the site before 2027.
It’s a remarkably quick rise for a company that wasn’t even around when OpenAI kicked off the generative AI boom with the launch of ChatGPT in late 2022. At that time, what’s now Nscale was part of Arkon Energy, which was established a year earlier to provide infrastructure for cryptocurrency mining. Nscale was spun out to address soaring demand for data centers capable of handling AI workloads.

Like CoreWeave, which went public this year and now sports a market cap of $58 billion, Nscale is combining data center space, power and lots of GPUs with its own software in order to an provide end-to-end service for AI infrastructure.
CoreWeave, which supplies infrastructure to Microsoft, Google, Nvidia and OpenAI, also has roots in crypto. Founded in 2017, the company built up its initial fleet of Nvidia GPUs for ethereum mining before pivoting to AI.
Nscale didn’t respond to a request for comment following this week’s announcements, but CEO Josh Payne, who previously founded Arkon, told CNBC in late July that the company was targeting two big problems in Europe. One is a lack of sufficient computing capacity and the other is a “very fragmented market.”
“What the continent needs is large AI infrastructure projects deploying compute [power],” Payne said, after the announcement with OpenAI for the Norway buildout. “The ecosystem can consume from the project to build AI products, to generate productivity growth and economic benefit.”
Payne wrote in a LinkedIn post on Wednesday that the agreement with Microsoft and Aker is a “huge win for European-owned AI infrastructure.”
Europe has been pushing the concept of “sovereign AI,” requiring data centers and AI workloads to be located and processed on European soil. Nscale has quickly emerged as an important player in the U.K.’s bid to evolve into a global leader in AI. In January, Britain laid out an AI “action plan,” promising to reduce bureaucracy to help its domestic AI sector thrive.
While Nscale is addressing the European market, many of its early partners are big U.S. AI vendors. They timed their announcements on Tuesday to President Donald Trump’s state visit to the U.K.
On Wednesday, Trump visited Windsor Castle and met with King Charles, Queen Camilla and other members of the royal family. His trip comes at a contentious moment for U.K. Prime Minister Keir Starmer, who is under pressure to bring stability to the country after the exit of Deputy Prime Minister Angela Rayner over a house tax scandal and a major cabinet reshuffle.
Microsoft headlined the U.K. announcements, committing $15.5 billion of new investment to computing equipment. The software giant said it plans to work with Nscale to construct what will become the U.K.’s largest supercomputer in Loughton, a suburban town in the English county of Essex.
The site will initially house 23,040 Nvidia Blackwell GPUs to be delivered in the first quarter of 2027. When it goes live, it will generate 50 megawatts of AI capacity, scalable to 90 megawatts, according to a statement from Nscale.
“No one can make that kind of capital investment unless they’ve got somebody already committed to spend the money once the work is complete, and that’s the role we’re playing,” Microsoft President Brad Smithsaid Tuesday, adding the deal represents a major vote of confidence in Nscale.
OpenAI said it would launch a U.K. version of Stargate through a partnership with Nscale and Nvidia. OpenAI will deploy 8,000 GPUs in the project’s first phase early next year, with the option to expand capacity to approximately 31,000 GPUs over time.
Stargate U.K. will operate across a number of sites in the country — one of the early ones being Cobalt Park, an industrial state in the Northern English city Newcastle. Stargate was initially spawned in the U.S. in January as part of President Trump’s effort to push investments in AI infrastructure.

Nvidia’s announcement on Tuesday included an investment of up to £11 billion ($15 billion) with Nscale and CoreWeave to boost U.K. AI infrastructure.
Nvidia CEO Jensen Huang separately revealed on Wednesday that the chipmaker had made a £500 million ($683 million) equity investment into Nscale.
“We convinced ourselves that Nscale could be a national champion for AI infrastructure in the U.K.,” Huang told journalists at a press conference in London.
Nick Patience, AI practice lead at the Futurum Group, told CNBC that Nscale is “a key part of Nvidia’s push in the U.K. market and an acknowledgment by the government that it has to do something to get the AI infrastructure built here, which has been a long slog.”
Rapid growth
After exiting stealth in May of last year, Nscale’s first public announcement came two months later, when the company partnered with UAE’s Open Innovation AI to deploy 30,000 GPUs. Around the same time, Nscale said it was acquiring Kontena, which was founded in 2018 and specialized in high-performance computing data centers.
The next month, Nscale announced an agreement with Asian telecom company Singtel to offer a “GPU-as-a-Service (GPUaaS),” and serve customers in Europe and Southeast Asia. Initially, Nscale’s infrastructure relied on GPUs from Advanced Micro Devices. Today, the startup promotes various offerings from market leader Nvidia.
Nscale’s big financing landed in December, when the company said it raised $155 million in a round led by Sandton Capital Partners, with participation from Kestrel0x1, Blue Sky Capital Managers and Florence Capital.
Sandton co-founder Rael Nurick said in the press release that with its “unique vertically integrated approach, Nscale is building the hyperscale AI platform to power AI at scale.”
Nscale said at the time that it had grown its AI data center pipeline to 1.3 gigawatts from 300 megawatts the prior year to and that it was aiming to have 350,000 GPUs running by the end of 2027.
By comparison, CoreWeave said at a banking conference last week that its portfolio consists of “about 2.2 gigawatts of capacity that’s coming online.” The company said in its IPO prospectus in March that its 32 data centers were running 250,000 GPUs.
It’s been a whirlwind few years for Payne, Nscale’s founder. While he was serving as executive chairman of Arkon, he was also operating chief at Australia’s Battery Future Acquisition Corp., a blank check company that says it’s “targeting critical battery minerals and related supply chains.”
He’s got a lot of work in front of him.
Building out AI data centers with costly GPUs is a capital intensive process that’s historically required a hefty amount of debt. CoreWeave had raised a total of $12.4 billion in debt through the end of 2024, in addition to well over $1 billion in equity financing before its IPO. It announced a $1.5 billion bond sale in July after a $2 billion debt offering in May.
Nscale was trying to raise $1.8 billion earlier this year through a private credit deal led by bankers at Goldman Sachs, according to Bloomberg.
In the December video tied to Nscale’s equity fundraising, Payne called it “one of the largest Series As raised in U.K., European history.” He said the company would use the cash to deploy up to another 4,000 GPUs in its data center in Norway and to develop up to 180 megawatts of capacity in the company’s portfolio.
The aim, Payne said, was to deploy 50,000 GPUs by the end of 2025 and 150,000 by the end of next year.
“The key challenges that we see in the market is the significant increase in density at the GPU level,” he said. “This funding allows us to scale up materially” he said, and to become “one of the largest players in Europe.”
