ATN breaks down the rise of digital health platforms offering personalized blood testing, including Function, Superpower and now, Hims & Hers
We’ve officially entered the blood-testing era, as investors pour money into tech-enabled digital health startups that claim to be at the forefront of a preventive healthcare revolution.
In November, Function Health raised $298 million in a Series B round that valued the company at a staggering $2.5 billion. The round was led by Redpoint Ventures and included other major venture funds, along with pro athletes, celebrities and investors including Matt Damon, Magic Johnson and Roku founder Anthony Wood.
Founded by Dr. Mark Hyman and Jonathan Swerdlin, Function allows users to test more than 100 blood biomarkers and receive personalized insights into their health, with an eye toward detecting and preventing potential health issues before they require serious medical attention.
The company says it can monitor early indicators of thousands of diseases, ranging from cancers to lead and mold toxicity to coronary artery disease.
“Proactive health has long been positioned as a luxury or an afterthought,” Dr. Hyman has told Athletech News. “That needs to change — and it’s exactly why we built Function: to make advanced diagnostics both accessible and actionable for everyone. Everyone deserves the right to know what is happening in their body.”
The new funding will also help fuel what Function is calling “medical intelligence,” an AI-powered system built to capture the deepest possible view of a person’s biology by unifying data from lab tests, imaging, wearables, and medical records, then layering it with research and clinical expertise to spot early warning signals.
“We’ve spent decades waiting until people are sick to act,” said Dr. Daniel Sodickson, a biomedical imaging expert who joined Function as its chief medical scientist and co-director of the company’s medical intelligence lab.
“Function changes that. Medical intelligence connects important signals — from blood to imaging to wearables — creating a continuously learning model of your health,” Dr. Sodickson added. “It’s not AI replacing doctors; it’s clinical expertise amplified by intelligent systems that never stop learning.”
Competitors Are Coming
Function currently leads the booming market for personalized blood testing, but it’s got some serious competition.
Telehealth giant Hims & Hers recently announced the launch of “Labs,” a similar service to Function that offers access to 120-plus lab tests and actionable advice based on those results.
Labs offers two pricing tiers, one that costs $199 per year and provides access to 50 biomarker tests and an advanced plan that offers over 120 biomarker tests and costs $499 annually.
“Lab results are at the center of decision-making in primary care, and we’re making them simpler, more personal and more actionable,” Hims & Hers chief medical officer Dr. Pat Carroll said. “Most chronic conditions are entirely preventable, but develop long before symptoms appear.”
Superpower, meanwhile, raised $30 million in a Series A round in April for its platform that provides users with biannual lab testing spanning over 100 biomarkers, along with an accompanying personalized health strategy.
Originally available for $499 per year, Superpower recently rolled out a $199 annual membership intended to make its preventive health services available to a broader market.
“We’re on a mission to bring the best of health to millions,” Superpower co-founder and president Max Marchione said. “Now we’re one step closer to doing just that. Just as tens of millions subscribe to affordable memberships for everyday essentials, we see a future where that same scale exists for a seminal health membership.”
Another similar platform, Hone Health, offers comprehensive biomarker blood testing, followed by a 45-minute physician consultation and customized treatment plan. The New York-based company closed a $33 million Series A funding round this year, bringing its total funding to $39 million.
“Healthcare is undergoing a generational reset,” Hone Health co-founder and CEO Saad Alam told ATN. “Prevention isn’t abstract anymore — it’s specific, measurable, and increasingly within reach. … Our role is to remove friction, eliminate gatekeeping, and give people a faster path to understanding what’s going on in their bodies.”
Are Wearables & Blood Testing the Next Frontier?
Wearable makers are getting in on the blood-testing game, too.
Whoop launched Whoop Advanced Labs in September, a service that allows people to combine biomarker blood testing results with personalized health insights from wearables.
“Whoop Advanced Labs bridges two worlds: lab diagnostics and 24/7 continuous monitoring,” said Will Ahmed, the founder and CEO of Whoop. “For the first time, our members can see how their blood biomarkers and daily behaviors connect in real time. This is all part of our path to becoming a health operating system that helps our members live better and longer.”
Fitness Brands Embrace Personalized Testing
It’s early days in the blood-testing arms race, but some fitness brands are already getting on board, partnering with health platforms to offer their members preferential access.
Equinox partnered with Function in 2024, initially offering the health platform’s services as part of Equinox Optimize, a $3,000-per-month longevity membership.
Since then, the sides have deepened their relationship. Now, all Equinox members can subscribe to Function for a discounted price of $249 per year. The companies also launched a joint venture in Equinox’s Women’s Health and Performance Initiative, which combines personalized training, advanced diagnostics and community-focused programming to address women’s physiological needs, including menstruation, fertility, postpartum and perimenopause.
Tone House, a popular boutique fitness studio in New York City, entered an exclusive partnership with Hone Health to give its members a 30% discount on a one-year Hone membership.
“We believe this partnership represents a unique and forward-thinking opportunity to create meaningful community engagement through a value-added experience in health and performance optimization,” said Tone House chief operating officer Elvira Yambot.
Expect to see more gyms, clubs and fitness studios follow the lead of Equinox and Tone House in the months and years to come.
