Doximity, the medical website that’s used by more than 80% of U.S. doctors, is now trying to protect its millions of members after a spike in harassment that started during the Covid pandemic.

The 13-year-old company has introduced a free service called DocDefender that can scrub a physician’s personal contact information from the internet. The technology scans dozens of the most common websites where a doctor’s information might reside and automatically initiates the removal process.

Doximity’s platform, which for years was described as LinkedIn for doctors, allows health-care workers to stay current on medical news, manage paperwork, find referrals and carry out telehealth appointments with patients. Since the Covid pandemic broke out in 2020, health-care workers have faced elevated levels of harassment and violence due largely to the politicization of masking, social distancing and vaccine requirements.

Doximity says the new feature is all about giving peace of mind to doctors so they can feel safer in their personal and professional lives and can focus on providing better care.

Dr. Amit Phull, chief physician experience officer at Doximity, said the feature is a service that users wanted. In March, more than 200 doctors traveled to Doximity’s headquarters in San Francisco to help the company workshop new ideas for its platform. When executives presented DocDefender, they received a resounding standing ovation. 

“We’ve gotten positive feedback before,” Phull told CNBC in an interview. “That was a first for us.” 

Two months after the workshopping event, Doximity conducted a survey of more than 2,000 doctors and found that 85% of them worry about whether patients will access their personal information online. That number is higher within certain high-stress specialties like physical medicine and rehabilitation, neurology, emergency medicine and psychiatry.

Phull, who practices as a physician in emergency medicine, said he’s felt concerned about his safety many times throughout his career. He carried out his trauma training in Chicago, where he treated several victims of gang-related violence. Phull said he was often thrust in the middle of complex conflicts that were out of his control, and he worried that people would find him online and retaliate.  

“If you find yourself in one of those high-intensity situations, and outside of the scope of your practice that conflict still persists, that online element can be kind of scary,” he said.  

Since the onset of the pandemic, many patients have a shorter fuse. 

“I’ve been swung at by patients,” he said. “We certainly deal with a lot of hostility.”

Phull said that in testing the technology, he found details like his phone number, his relatives, his past and current addresses — and even a map to his old home on more than 25 websites. Now that he knows that information is being removed, Phull said he and his wife feel a little more comfortable.  

DocDefender users can monitor the removal process directly through Doximity’s interface, and they will receive regular follow-up reports about the status of their online presence. Additional scans will also be carried out periodically to identify any new listings. 

The service will be available to all doctors on Doximity starting Wednesday, and will expand to nurse practitioners and others over time. 

‘Opportunity to think very long term’

In addition to reaching more than 80% of U.S. doctors, Doximity says it’s also used by 50% of nurse practitioners and physician assistants. 

The platform verifies members to ensure that they’re practicing health-care professionals. Approved clinicians can use Doximity for free, as the company primarily generates revenue through its hiring, marketing and telehealth solutions.  

Doximity debuted on the New York Stock Exchange in June 2021, during the peak of the tech bull market. Its market cap climbed to $9.4 billion in its first day of trading, but has since fallen below $4 billion.

CEO Jeff Tangney, who co-founded Doximity in 2010, told CNBC the company is able to offer DocDefender for free in part because of its strong profit margins. 

“We just have the opportunity to think very long term and to invest in things that doctors really want, and that’s what we’re doing here,” he said.

Dr. Azlan Tariq, a physical medicine and rehabilitation doctor and the chief clinical officer at a  physiatry organization called Medrina, had early access to DocDefender.

PM&R physicians often deal with patients suffering chronic pain and are responsible for prescribing — and denying — medications like opioids. Around 96% of PM&R doctors reported feeling concerned about their online privacy in Doximity’s May survey.

Tariq said he’s taken steps to try and protect both his online identity and his physical safety, leaving social media sites like Facebook and taking down personal information elsewhere. He tries not to shop near his clinic to avoid disgruntled patients, and he said he’s always paying attention to his environment.

On one occasion, a patient was waiting for Tariq in the parking lot outside of his clinic. While the patient ultimately meant no harm, Tariq said he had to assume the worst. 

“You just think about exits. How can I get out of this?” he said. “Can I get back in the car? Can I get the door of the clinic and go behind? Those are just the normal behaviors.”

He added that some of his colleagues seriously consider carrying a gun. 

Since testing DocDefender, Tariq said he’s already noticed some of his personal information has been removed online, adding he feels a little more at ease.

Still, DocDefender doesn’t entirely remove the risk of being found. Dr. Jasdeep Gill, a psychiatrist, said there are some databases for Medicare and Medicaid that list doctors’ information, as well as websites that use their specific provider numbers. 

“Within the last two weeks, I’ve had two different people call my cell phone and request care, and I don’t know how they found my cellphone number,” said Gill, commenting that DocDefender is a step in the right direction to guard against this. “Trying to figure out how they got that information left me feeling just kind of uncomfortable.”

Gill works with patients, including some who are incarcerated, dealing with schizophrenia, bipolar disorder, depression and substance abuse. He said he started taking the risks more seriously after a patient made threats against him while he was in residency. 

Gill said he paid $20 a month for an information-removal service, but that process was “clunky” and “cumbersome.” He called Doximity’s tool a “really easy service to use” and sees it as a way for physicians to maintain the boundary between their professional and private lives. 

“Our background history of where we live, who we’re married to, what our cellphone numbers are, are things that are personal and that should be kept separate from the public’s view,” Gill said. “By creating that separation, it allows us to just do our jobs and focus on health care instead of worrying about safety.”

TikTok signs agreement to create new U.S. joint venture, memo says

TikTok signs agreement to create new U.S. joint venture, memo says

TikTok CEO Shou Zi Chew told employees on Thursday that the company’s U.S. operations will be housed in a new joint venture.

The entity is named TikTok USDS Joint Venture LLC, according to a memo sent by Chew and obtained by CNBC. As part of the joint venture, Chew said the company has signed agreements with the three managing investors: Oracle, Silver Lake, and Abu Dhabi-based MGX. He said that the deal’s “closing date” is Jan. 22.

Under a national security law, which the Supreme Court upheld in January, China-based ByteDance was required to divest TikTok’s U.S. operations or face an effective ban in the country. In September, President Donald Trump signed an executive order approving a proposed deal that would keep TikTok operational in the U.S. by meeting the requirements of a law originally signed by former President Joe Biden.

Chew noted that the new TikTok joint venture would be “majority owned by American investors, governed by a new seven-member majority-American board of directors, and subject to terms that protect Americans’ data and U.S. national security.”

The U.S. joint venture will be 50% held by a consortium of new investors, including Oracle, Silver Lake and MGX with 15% each. Just over 30% will be held by affiliates of certain existing investors of ByteDance, and 19.9% will be retained by ByteDance, the memo said.

The TikTok chief said the entity will be responsible for protecting U.S. data, ensuring the security of its prized algorithm, content moderation and “software assurance.” He added that the joint venture will “have the exclusive right and authority to provide assurances that content, software, and data for American users is secure.”

In addition to being an investor, Oracle will serve as the “trusted security partner” in charge of auditing and validating that it complies with “agreed upon National Security Terms,” the memo said. Sensitive U.S. data will be stored in Oracle’s U.S.-based cloud computing data centers, Chew wrote.

The new TikTok entity will also be tasked with retraining the video app’s core content recommendation algorithm “on U.S. user data to ensure the content feed is free from outside manipulation,” the memo said.

Chew noted that TikTok global U.S. entities “will manage global product interoperability and certain commercial activities, including e-commerce, advertising, and marketing.”

Under Trump’s executive order in September, the attorney general was blocked from enforcing the national security law for a 120-day period in order to “permit the contemplated divestiture to be completed,” allowing the deal to finalize by Jan 23.

Google and Nvidia VC arms back vibe coding startup Lovable at $6.6 billion valuation

Google and Nvidia VC arms back vibe coding startup Lovable at .6 billion valuation

The VC arms of Google and Nvidia have invested in Swedish vibe coding startup Lovable’s $330 million Series B at a $6.6 billion valuation, the company announced on Thursday.

The news confirms an earlier story from CNBC, which reported on Tuesday that Lovable had raised at that valuation, trebling its valuation from its previous round in July, and that the investors included U.S. VC firms Accel and Khosla Ventures.

CapitalG, one of Google’s VC divisions, and Menlo Ventures led the round. Alongside Accel and Khosla, Nvidia venture arm NVentures, actor Gwyneth Paltrow’s VC firm Kinship Ventures, Salesforce Ventures, Databricks Ventures, Atlassian Ventures, T.Capital, Hubspot Ventures, DST Global, EQT Global, Creandum and Evantic also participated.

The fresh funds take Lovable’s total raised in 2025 to over $500 million.

"Everyone can be a developer of software," says Lovable CEO

“Lovable has done something rare: built a product that enterprises and founders both love,” said Laela Sturdy, managing partner at CapitalG in a statement accompanying the announcement.

“The demand we’re seeing from Fortune 500 companies signals a fundamental shift in how software gets built.”

Lovable’s platform uses AI models from providers like OpenAI and Anthropic to help users build apps and websites using text prompts, without technical knowledge of coding.

The startup reported $200 million in annual recurring revenue (ARR) in November, just under a year after achieving $1 million in ARR for the first time. It was founded in 2023 by Anton Osika and Fabian Hedin.

Vibe coding startups have seen big interest from VCs in recent times, as investors bet on their promise of drastically reducing the time it takes to create software and apps.

In the U.S., Anysphere, which created coding tool Cursor, raised $2.3 billion at a $29.3 billion valuation in November. In September, Replit hit a $3 billion price tag after picking up $250 million and Vercel closed a $300 million round at a $9.3 billion valuation.

Micron stock pops 15% as AI memory demand soars: 'We are more than sold out'

Micron Technology‘s stock jumped 15% after the company signaled robust demand for its memory chips and blew away fiscal first-quarter estimates.

During an earnings call with analysts, Micron, which makes memory storage used for computers and artificial intelligence servers, said data center needs have fueled greater demand for its products.

Micron said it expects the total addressable market for high-bandwidth memory to hit $100 billion by 2028, growing at a 40% compounded annual growth rate. Management also upped its capital expenditures guidance to $20 billion from $18 billion.

“We are more than sold out,” said business chief Sumit Sadana. “We have a significant amount of unmet demand in our models and this is just consistent with an environment where the demand is substantially higher than supply for the foreseeable future.

Micron topped Wall Street estimates for the fiscal first quarter and issued blowout guidance.

The company reported adjusted earnings of $4.78 per share on $13.64 billion in revenue, surpassing LSEG estimates for earnings of $3.95 per share and $12.84 billion in sales.

Revenues in the current quarter are expected to hit about $18.70 billion, blowing past the $14.20 billion expected by LSEG. Adjusted earnings are forecast to reach $8.42, versus expectations of $4.78 per share.

JPMorgan upped its price target on the stock following the results, citing the favorable pricing setup, while Bank of America upgraded shares to a buy rating.

Morgan Stanley called the results the best revenue and net income upside in the “history of the U.S. semis industry” outside of Nvidia.

“If AI keeps growing as we expect, we believe that the next 12 months are going to have broader coat tails to the AI trade than just the processor names and memory would be the biggest beneficiary,” analysts wrote.
