Heartflow stock listing and IPO date draw near: AI-powered medtech aims for $1.3 billion valuation
Heartflow, a California-based medtech company that utilizes AI with imaging and diagnostics software to help evaluate cardiac and coronary diseases, is looking to list shares on the Nasdaq.
In paperwork filed on Friday with the Securities and Exchange Commission (SEC), Heartflow said it plans to offer 12.5 million shares, priced between $15 and $17.
That could potentially raise more than $208 million. According to Reuters, Heartflow's target valuation could be as high as $1.3 billion. The company plans to trade under the ticker 'HTFL.'

Personalized 3D-models of people's hearts
Heartflow uses AI and other technology to scan patients for coronary and cardiac problems, creating three-dimensional models of patients' hearts. The Food and Drug Administration (FDA) gave the software the green light in 2022, and it's now being used in some markets to diagnose patients.
Additionally, the company got a leg up last year when the U.S. Centers for Medicare and Medicaid Services (CMS) expanded Medicare coverage to include platforms that use imaging results to look for signs of coronary disease, and the American Medical Association (AMA) issued a new Category I CPT code for those platforms. That gives doctors and clinics the go-ahead to start using the technology on a broader scale starting next year.
According to the company's SEC filing, Heartflow says that as of the end of March 2025, it's been used to assess more than 400,000 patients.
Revenues are growing but profits are elusive
Heartflow generated $125.8 million in 2024, a 44% increase over the $87.2 million it made the year before, the company says. Revenue likewise grew 39% for the first quarter of 2025 to $37.2 million.
However, the company saw a net loss of $96.4 million in 2024, wider than its net loss of $95.7 million in 2023. It warns in the filing that it expects to incur 'substantial losses in the foreseeable future [and] may not be able to achieve or sustain profitability.'
Bain Capital, Panorama Point Partners, and Capricorn Investment Group are among Heartflow's backers, according to Crunchbase. Bain led its most recent fundraising round, a Series F round in 2023, which raised $215 million.
This is not the first time that Heartflow has attempted to go public. The company had planned to merge with a special purpose acquisition company during the SPAC frenzy of the early pandemic years, but it halted the plan in 2022, citing 'unfavorable market conditions,' as Fierce Biotech reported.
Heartflow's IPO comes on the heels of another growing medtech company's public debut. Carlsmed, which specializes in AI-driven spine surgery technology, recently went public as well, with shares trading on July 23. Since then, the stock is down around 4.5%.
Heartflow has not said when it plans to list its stock. Fast Company reached out for more details on the timeline and will update this post if we hear back.

A cancer diagnosis can cause out-of-pocket costs to surge, study finds
A cancer diagnosis increases privately insured patients' monthly out-of-pocket costs, which also rise as the disease progresses, new research shows. Out-of-pocket costs jumped by $592.53 per month for the six months after a diagnosis, according to a recent report published in JAMA Open Network. The study underscores the financial toll a cancer diagnosis can take on individuals, even for those who are insured but don't yet qualify for Medicare. While cancer tends to strike later in life, when most patients in treatment are receiving Medicare benefits, a cancer diagnosis can pose an undue financial burden on younger people with private insurance, the report found. Those out-of-pocket costs highlight the need for policy reform, the report said. The research "underscores the need for policies such as paid sick leave that address both insurance continuity and financial assistance, especially for patients with more advanced cancer," the report states. Out-of-pocket costs increased based on a patient's cancer progression, the analysis found. Patients with stage 0 cancer saw their costs rise by $462 per month compared to non-cancer patients, while stage 4 cancer cost people with private insurance an additional $719.97 per month in out of pocket costs. Costs rise as the disease progresses because patients typically require more treatment during cancer's later stages, leading to greater medical expenditures. "This result seems straightforward; later-stage disease is associated with more intensive workup and treatment that can drive higher medical expenditures," the report states. Researchers analyzed medical claims records from the Surveillance, Epidemiology, and End Results (SEER) cancer registry to compare the out-of-pocket costs of privately insured individuals under the age of 65 who were diagnosed with breast, colorectal, and lung cancer, to those without cancer. New research from the American Cancer Society shows that as more people aged 45-49 undergo screening for colon cancer, more early stage diagnoses are being made.

Tips to help manage your buy now, pay later loans
NEW YORK (AP) — Between rising prices and dwindling job growth, using 'buy now, pay later' on everything from concert tickets to fast food deliveries is becoming increasingly appealing. But greater use could also mean greater trouble, as more people fall behind on repaying these loans. Buy now, pay later loans gained popularity during the pandemic, especially among young people. While these loans can help you make large purchases without paying interest or undergoing a hard inquiry in your credit report, they can also easily be overused. About 4 in 10 Americans under the age of 45 say they've used "buy now, pay later″ services when spending on entertainment or restaurant meals, or when paying for essentials like groceries or medical care, according to a poll from The Associated Press-NORC Center for Public Affairs Research. Buy now, pay later loans were not previously reported to the three major credit reporting bureaus. But consumers will soon see the impact of buy now, pay later loans on their FICO credit scores. Whether you're a first-time or recurring user of buy now, pay later plans, here are some expert recommendations to use this tool responsibly. Focus on needs vs. wants Buy now, pay later plans divide purchases in monthly installments, typically in four payments. These loans are marketed as having low or no interest. Klarna, Afterpay, PayPal Later and Affirm are among the most popular buy now, pay later companies. These loans should ideally be used for large purchases or necessities, said Lauren Bringle, Accredited Financial Counselor at Self Financial. Bringle recommends asking yourself these questions before purchasing: Can I survive without this purchase right now? Do I need it for work, school, or a basic household need? Buy now, pay later is best used when you have a plan for the purchase, not for impulse buys. For example, when you need to buy a computer for school or a new refrigerator for your house, recommended Tyler Horn, head of planning at Origin, a budgeting app. Pause before purchasing Before deciding to take out a buy now, pay later loan, it's a good idea to pause and consider if it's the best financial decision for you, recommended Erika Rasure, Chief Financial Wellness advisor for Beyond Finance. Buy now, pay later plans can be positive budgeting tools when used strategically. However, it's essential you know your spending behaviors before using them, said Rasure. If you're an emotional spender, it might be hard for you to moderate your use of this tool and you could end up adding to your financial stress. 'Buy now, pay later can become a coping mechanism rather than a financial tool that can get you a good deal or improve your cash flow,' said Rasure. If you have other payments due, such as credit card or student loan payments, consider how a buy now, pay later loan will add to your monthly payments, recommended Sarah Rathner, Senior Writer for NerdWallet. Read the fine print Like credit cards, each buy now, pay later loan has terms and conditions that can vary by purchase and providers. It's crucial that you know what you're agreeing to before you sign up, recommended Michael Savino, Chief Lending Officer at Municipal Credit Union. 'Always read the fine print. Understand fees, repayment schedules, and what happens if you miss a payment or go into default,' said Savino. In general, if you miss a buy now, pay later payment, you can face fees, interest, or the possibility of being banned from using the services in the future. Avoid stacking BNPL loans You can easily run into difficulty keeping up with the cost and schedule of your repayments if you're trying to simultaneously pay off two, three or more loans, Savino said. 'Juggling multiple plans creates a blind spot and overall debt load, and multiple repayment dates are hard to manage,' Savino said. "So more loans makes it more difficult to budget.' The best approach: Stay mindful of your overall spending, and limit the number of buy now, pay later loans. Keep track of your loan(s) Whether or not you're paying for multiple buy now, pay later purchases at once, you want to be aware of where your money is going at any given time, recommended Courtney Alev, consumer advocate at Credit Karma. 'Buy now, pay later often requires automatic payments, so you want to make sure that your account is funded so that those payments are processing successfully,' recommended Jennifer Seitz, director of education at Greenlight, a financial literacy app for families. There are many ways to track your loan payments — from setting a reminder on your calendar, to creating an intricate excel spreadsheet or tracking them on an app, said Jesse Mecham, founder of the budgeting app YNAB. Finding the best method that works for you will help you stay on track and avoid late fees. Make buy now, pay later work for you For shoppers with low credit scores or no credit history, buy now, pay later loans can seem like the best, if not the only, loan option. If used moderately and responsibly, these short-term loans can be a positive lending exercise, said Savino. 'It allows you to to establish a baseline (and) get access to other affordable credit options that you can leverage that will ultimately provide financial wellness,' he added. Still, NerdWallet's Rathner emphasized that shoppers using these tools always remember that buy now, pay later is a form of borrowing money. 'It just kind of feels like you're given a little extra time to pay back," Rathner said. "But the reality is, if you miss payments, it can hurt your credit, much like missing payments with any other loan.' —— The Associated Press receives support from Charles Schwab Foundation for educational and explanatory reporting to improve financial literacy.
