At first look, the latest machine from PNOĒ seems like one thing a comic-book villain would possibly put on. The masks, which covers the nostril and mouth and straps across the again of the top, bears greater than a passing resemblance to the one worn by Bane, Batman’s hulking nemesis. However its goal is way extra benign; it measures how a lot oxygen you devour and the way a lot carbon dioxide you exhale, then turns that knowledge into recommendation about methods to eat, practice, and, the corporate hopes, dwell longer.
PNOĒ, which relies in Malden, Massachusetts, and has operations in Athens, Greece, is getting ready to launch the PNOĒ 2.0 on October 1. The large change from its present machine is that customers can administer the take a look at themselves. In keeping with co-founder and CEO Apostolos Atsalakis, somebody can stroll right into a health club, “simply put on the masks, push the button, sit down,” and breathe for eight minutes. “That’s it. It’s that straightforward,” he stated not too long ago, speaking with this editor over a Zoom name from the corporate’s Athens location.
That issues as a result of PNOĒ’s present machine requires a skilled operator, which limits the place it may be used. A self-serve model may open the door to health facilities with out devoted workers and doubtlessly even pharmacies, Atsalakis stated.
The science behind PNOĒ isn’t new. Metabolic testing, which analyzes the gases in an individual’s breath to gauge how their physique produces power, has been round for greater than a century. For many years, it has been the gold customary for measuring VO₂ max, the utmost quantity of oxygen the physique can use throughout train and a extensively used measure of cardiorespiratory health. However the checks have historically required cumbersome, costly tools discovered primarily in sports activities labs and hospitals, which is why they’ve largely been the province of elite athletes and govt wellness packages.
What 10-year-old PNOĒ guarantees is identical accuracy in a conveyable package deal, paired with software program that interprets the outcomes into suggestions. “We made it accessible to everybody,” Atsalakis stated.
The corporate says its take a look at captures 23 biomarkers, together with (past measuring VO₂ max) one’s resting metabolic price (what number of energy the physique burns at relaxation), and metabolic flexibility (how properly the physique switches between burning fats and carbohydrates). Atsalakis argues that these metrics reply questions that blood checks can’t, corresponding to what number of energy an individual wants or how they need to practice.
The timing is nice for PNOĒ. VO₂ max has turn into a buzzword amongst longevity fanatics, thanks partly to analysis linking greater cardiorespiratory health to decrease mortality. Atsalakis calls VO₂ max the strongest predictor of human longevity, and he sees his firm’s knowledge as a type of scorecard for the booming wellness business.
The brand new machine is smaller and extra compact than its predecessor, with fewer components, which Atsalakis stated makes it extra dependable. It was designed with Milan-based Design Group Italia over what Atsalakis described as “lots, lots, a lot of iterations,” since a self-administered metabolic testing machine hadn’t been carried out earlier than.
It additionally addresses a query that post-pandemic customers are prone to ask: who wore it final? The reply: it doesn’t matter, because the electronics detach from the silicone masks and straps, so a number of individuals can share the expensive {hardware} whereas every consumer retains their very own masks.
For all its scientific ambitions, PNOĒ is cautious about what it claims. The machine isn’t cleared by the U.S. Meals and Drug Administration, and Atsalakis stated that “we don’t present medical suggestions.” As a substitute, PNOĒ considers itself a wellness machine. “It’s like a physique composition machine, like a scale,” he stated. “A health care provider can not prescribe remedy primarily based on our outcomes.”
That might change down the highway. Researchers have lengthy explored whether or not compounds in human breath can sign ailments corresponding to most cancers, and Atsalakis believes the corporate’s rising trove of information may ultimately assist it flag well being points. However he acknowledged that full diagnoses are “undoubtedly a few years away,” with regulatory hurdles doubtless stretching that timeline additional. “We’re not there but,” he stated.
PNOĒ traces its roots to Atsalakis’s PhD work in sensing applied sciences on the College of Cambridge, when wearables had been taking off and he grew to become fascinated by what the breath may reveal in regards to the physique. He co-founded the corporate with Panos Papadiamantis, a childhood good friend who’s now the corporate’s chief product officer.
The startup went by way of Y Combinator’s Winter 2019 batch, again when “longevity” was not but the business it’s at the moment. It has since raised about $22 million, together with a not too long ago closed $11 million spherical, from traders together with 50 Years and Google Maps co-founder Lars Rasmussen, who’s himself now primarily based in Athens.
PNOĒ sells solely to companies, which then provide the take a look at to their clients. Its shoppers embrace Equinox, the place it’s out there at virtually all golf equipment, stated Atsalakis, in addition to 4 Seasons inns, Crimson Bull, the NBA, the Mount Sinai Well being System, and the med spa chain Restore Hyper Wellness.
About 85% of its enterprise comes from the U.S., which Atsalakis described as “by far essentially the most superior market globally” for longevity. The corporate is now increasing in Europe and, by way of companions, in Latin America and Asia.
Companies pay a subscription starting from $400 a month to greater than $1,000, which covers the {hardware}, software program, coaching, and advertising and marketing supplies, a package deal Atsalakis calls a “enterprise in a field.” PNOĒ additionally hyperlinks its outcomes to the providers a enterprise sells, so a health club or spa can suggest particular choices primarily based on a buyer’s take a look at. Many consumers use the take a look at throughout onboarding, Atsalakis stated, positioning it someplace between a full scientific workup and the estimates individuals get from their smartwatches.
That center floor is more and more crowded. Apple, Garmin, and Whoop all estimate VO₂ max from heart-rate knowledge, whereas shopper units like Lumen analyze breath to gauge fats and carb burning. On the excessive finish, conventional metabolic carts stay the usual in labs and hospitals.
PNOĒ, which employs 110 individuals, says it not too long ago turned worthwhile, whereas rising greater than 100% a yr. Atsalakis stated the corporate plans to boost a Sequence B inside the subsequent six to 12 months because it tries to place its masks — Bane comparisons and all — in entrance of extra faces.
