PNOĒ, a Massachusetts-based health tech company, is launching a self-administered breath testing device on 1 October. The PNOĒ 2.0 mask measures oxygen consumption and carbon dioxide exhalation to provide insights on metabolism, fitness, and longevity. The new device eliminates the need for trained operators, potentially expanding access to gyms and pharmacies. It analyses 23 biomarkers, including VO₂ max and resting metabolic rate, through an eight-minute breathing test. The 10-year-old startup recently raised $11 million, bringing total funding to $22 million. Investors include 50 Years and Google Maps co-founder Lars Rasmussen. The company sells subscriptions to businesses like Equinox and Four Seasons for $400 to over $1,000 monthly. PNOĒ employs 110 people and says it recently became profitable whilst growing over 100% annually. The company plans a Series B funding round within six to 12 months.
