Sword Health, a startup focused on helping people deal with pain through digital services, is expanding into mental health and has raised additional capital to fuel its growth.
The 10-year-old company is introducing Mind, which uses a combination of artificial intelligence, hardware and human mental health professionals to treat patients with mild depression and anxiety. Sword said Mind will help users access care whenever they need it, rather than during sporadic, hourlong appointments.
“It’s really a breakthrough in terms of how we address mental health, and this is only possible because we have AI,” Sword CEO Virgílio Bento told CNBC in an interview.
Also on Tuesday, Sword announced a $40 million funding round, led by General Catalyst, in a deal that values the company at $4 billion. The fresh cash will support Sword’s efforts to grow through acquisitions, as well as its global expansion and AI model development, the company said.
The round included participation from Khosla Ventures, Comcast Ventures and other firms. Sword had raised a total of more than $450 million as of September, according to PitchBook.
The financing lands as the digital health market shows signs of recovery following a difficult post-Covid stretch, when rising inflation, higher interest rates and a return to in-person activities led to a dramatic retreat in the industry.
Earlier this month, Omada Health, which offers virtual care programs to supports patients with chronic conditions such as diabetes and hypertension, held its Nasdaq debut, though the stock is trading below its initial public offering price. Weeks before that, digital physical therapy provider Hinge Healthhit the New York Stock Exchange. The shares are trading a few dollars above their offer price.
Sword, which was founded in Portugal and is now based in New York, offers tools for digital physical therapy, pelvic health and movement health to help patients manage pain from home and avoid other treatments such as opioids and surgery. Patients can sign up for Sword if it’s supported by their employer or their health plan.
Mind users will receive a wrist wearable called the “M-band” that can measure environmental and physiological signals such as heart rate, sleep and the lighting in a user’s environment. Mind also includes access to an AI Care agent and human mental health professionals, who can deliver services such as traditional talk therapy.
Bento said a human is always involved with a patient’s care, and that AI is not making clinical decisions.
For example, if a patient has an anxiety attack, Sword’s AI will recognize that and could ask a clinician to approve some physical activity for later that day to help with recovery. The clinician would either approve the physical activity that the AI suggested, or override it and propose something else.
“You have an anxiety issue today, and the way you’re going to manage is to talk about it one week from now? That just doesn’t work,” Bento said. “Mental health should be always on, where you have a problem now, and you can have immediate help in the moment.”
Bento said Sword has some clients that have been on a waiting list for Mind, and the startup has been testing the offering with some of its design partners. He said early users have approved of Mind’s personalized approach and convenience.
“We believe that it is really the future of how mental health is going to be delivered in the future, by us and by other companies,” Bento said. “AI plays a very important role, but the use of AI — and I think this is very important — needs to be used in a very smart way.”

Elon Musk on Monday said he does not support a merger between xAI and Tesla, as questions swirl over the future relationship of the electric automaker and artificial intelligence company.
X account @BullStreetBets_ posted an open question to Tesla investors on the social media site asking if they support a merger between Tesla and xAI. Musk responded with “No.”
The statement comes as the tech billionaire contemplates the future relationship between his multiple businesses.
Overnight, Musk suggested that Tesla will hold a shareholder vote at an unspecified time on whether the automaker should invest in xAI, the billionaire’s company that develops the controversial Grok AI chatbot.
Last year, Musk asked his followers in an poll on social media platform X whether Tesla should invest $5 billion into xAI. The majority voted “yes” at the time.
Musk has looked to bring his various businesses closer together. In March, Musk merged xAI and X together in a deal that valued the artificial intelligence company at $80 billion and the social media company at $33 billion.
Musk also said last week that xAI’s chatbot Grok will be available in Tesla vehicles. The chatbot has come under criticism recently, after praising Adolf Hitler and posting a barrage of antisemitic comments.

Coincidentally, OpenAI CEO Sam Altman announced early Saturday that there would be an indefinite delay of its first open-source model yet again due to safety concerns. OpenAI did not immediately respond to a CNBC request for comment on Kimi K2.
In its release announcement on social media platforms X and GitHub, Moonshot claimed Kimi K2 surpassed Claude Opus 4 on two benchmarks, and had better overall performance than OpenAI’s coding-focused GPT-4.1 model, based on several industry metrics.
“No doubt [Kimi K2 is] a globally competitive model, and it’s open sourced,” Wei Sun, principal analyst in artificial intelligence at Counterpoint, said in an email Monday.
Cheaper option
“On top of that, it has lower token costs, making it attractive for large-scale or budget-sensitive deployments,” she said.
The new K2 model is available via Kimi’s app and browser interface for free unlike ChatGPT or Claude, which charge monthly subscriptions for their latest AI models.
Kimi is also only charging 15 cents for every 1 million input tokens, and $2.50 per 1 million output tokens, according to its website. Tokens are a way of measuring data for AI model processing.
In contrast, Claude Opus 4 charges 100 times more for input — $15 per million tokens — and 30 times more for output — $75 per million tokens. Meanwhile, for every one million tokens, GPT-4.1 charges $2 for input and $8 for output.
Moonshot AI said on GitHub that developers can use K2 however they wish, with the only requirement that they display “Kimi K2” on the user interface if the commercial product or service has more than 100 million monthly active users, or makes the equivalent of $20 million in monthly revenue.
Hot AI market
Initial reviews of K2 on both English and Chinese social media have largely been positive, although there are some reports of hallucinations, a prevalent issue in generative AI, in which the models make up information.
Still, K2 is “the first model I feel comfortable using in production since Claude 3.5 Sonnet,” Pietro Schirano, founder of startup MagicPath that offers AI tools for design, said in a post on X.
Moonshot has open sourced some of its prior AI models. The company’s chatbot surged in popularity early last year as China’s alternative to ChatGPT, which isn’t officially available in the country. But similar chatbots from ByteDance and Tencent have since crowded the market, while tech giant Baidu has revamped its core search engine with AI tools.
Kimi’s latest AI release comes as investors eye Chinese alternatives to U.S. tech in the global AI competition.
Still, despite the excitement about DeepSeek, the privately-held company has yet to announce a major upgrade to its R1 and V3 model. Meanwhile, Manus AI, a Chinese startup that emerged earlier this year as another DeepSeek-type upstart, has relocated its headquarters to Singapore.
Over in the U.S., OpenAI also has yet to reveal GPT-5.
Work on GPT-5 may be taking up engineering resources, preventing OpenAI from progressing on its open-source model, Counterpoint’s Sun said, adding that it’s challenging to release a powerful open-source model without undermining the competitive advantage of a proprietary model.
“Kimi-Researcher represents a paradigm shift in agentic AI,” said Winston Ma, adjunct professor at NYU School of Law. He was referring to AI’s capability of simultaneously making several decisions on its own to complete a complex task.
“Instead of merely generating fluent responses, it demonstrates autonomous reasoning at an expert level — the kind of complex cognitive work previously missing from LLMs,” Ma said. He is also author of “The Digital War: How China’s Tech Power Shapes the Future of AI, Blockchain and Cyberspace.”

Nvidia CEO Jensen Huang has downplayed U.S. fears that his firm’s chips will aid the Chinese military, days ahead of another trip to the country as he attempts to walk a tightrope between Washington and Beijing.
In an interview with CNN aired Sunday, Huang said “we don’t have to worry about” China’s military using U.S.-made technology because “they simply can’t rely on it.”
“It could be limited at any time; not to mention, there’s plenty of computing capacity in China already,” Huang said. “They don’t need Nvidia’s chips, certainly, or American tech stacks in order to build their military,” he added.
The comments were made in reference to years of bipartisan U.S. policy that placed restrictions on semiconductor companies, prohibiting them from selling their most advanced artificial intelligence chips to clients in China.
Huang also repeated past criticisms of the policies, arguing that the tactic of export controls has been counterproductive to the ultimate goal of U.S. tech leadership.
“We want the American tech stack to be the global standard … in order for us to do that, we have to be in search of all the AI developers in the world,” Huang said, adding that half of the world’s AI developers are in China.
That means for America to be an AI leader, U.S. technology has to be available to all markets, including China, he added.
Washington’s latest restrictions on Nvidia’s sales to China were implemented in April and are expected to result in billions in losses for the company. In May, Huang said chip restrictions had already cut Nvidia’s China market share nearly in half.
Last week, the Nvidia CEO met with U.S. President Donald Trump, and was warned by U.S. lawmakers not to meet with companies connected to China’s military or intelligence bodies, or entities named on America’s restricted export list.
According to Daniel Newman, CEO of tech advisory firm The Futurum Group, Huang’s CNN interview exemplifies how Huang has been threading a needle between Washington and Beijing as it tries to maintain maximum market access.
“He needs to walk a proverbial tightrope to make sure that he doesn’t rattle the Trump administration,” Newman said, adding that he also wants to be in a position for China to invest in Nvidia technology if and when the policy provides a better climate to do so.
But that’s not to say that his downplaying of Washington’s concerns is valid, according to Newman. “I think it’s hard to completely accept the idea that China couldn’t use Nvidia’s most advanced technologies for military use.”
He added that he would expect Nvidia’s technology to be at the core of any country’s AI training, including for use in the development of advanced weaponry.
A U.S. official told Reuters last month that China’s large language model startup DeepSeek — which says it used Nvidia chips to train its models — was supporting China’s military and intelligence operations.
On Sunday, Huang acknowledged there were concerns about DeepSeek’s open-source R1 reasoning model being trained in China but said that there was no evidence that it presents dangers for that reason alone.
Huang complimented the R1 reasoning model, calling it “revolutionary,” and said its open-source nature has empowered startup companies, new industries, and countries to be able to engage in AI.
“The fact of the matter is, [China and the U.S.] are competitors, but we are highly interdependent, and to the extent that we can compete and both aspire to win, it is fine to respect our competitors,” he concluded.
