Introduction: From Lab Bench to Gym Floor
On October 1, PNOĒ will roll out the PNOĒ 2.0, a self‑serve metabolic testing device that translates laboratory‑grade breath analysis into a consumer‑friendly experience. The company, founded by Apostolos Atsalakis and Panos Papadiamantis, has already secured high‑profile B2B clients such as Equinox, Four Seasons, Red Bull, the NBA, and Mount Sinai Health System. With a fresh $11 million infusion and a total funding tally of roughly $22 million, the startup is poised to redefine how fitness facilities, pharmacies, and wellness centers assess cardiorespiratory fitness and metabolic health.
The launch is more than a product announcement; it signals a shift in the wellness industry toward data‑driven personalization. By allowing users to “wear the mask, push the button, sit down,” PNOĒ 2.0 eliminates the need for trained technicians, opening the door for scalable, on‑demand health insights.
Why It Matters: The Value of Portable Metabolic Data
Bridging the Gap Between Clinical and Consumer
Traditional metabolic testing requires bulky gas‑exchange analyzers, trained operators, and a controlled environment—factors that keep the technology confined to research labs and elite sports facilities. PNOĒ 2.0 compresses that capability into an eight‑minute, self‑administered test that can be performed in a gym locker room or a pharmacy consultation area.
- Accessibility: The device is classified as a “wellness” product, similar to a smart scale, meaning it can be offered without FDA clearance. This lowers regulatory barriers and speeds time‑to‑market.
- Actionable Insights: By delivering VO₂ max, resting metabolic rate (RMR), and metabolic flexibility metrics, the device equips trainers and nutritionists with concrete data to tailor programs.
- Engagement: Users receive immediate, personalized recommendations for diet and training, increasing adherence to wellness plans.
Health Implications
VO₂ max is a well‑established predictor of longevity, while metabolic flexibility indicates how efficiently the body switches between fat and carbohydrate oxidation—a key factor in weight management and metabolic disease prevention. Providing these metrics at scale could help identify early signs of insulin resistance or cardiovascular risk, prompting preventive interventions before clinical symptoms emerge.
Technical Breakdown: Inside the PNOĒ 2.0
Core Sensor Architecture
PNOĒ 2.0 measures oxygen consumption (VO₂) and carbon dioxide production (VCO₂) using a dual‑sensor flow‑through system. The hardware, designed by Design Group Italia, features:
- Compact Flow Cell: Reduced internal volume compared to the original model, improving response time and reliability.
- Silicone Mask & Straps: Individually assigned to users for hygiene; the electronic module detaches for cleaning.
- Modular Electronics: A single shared processing unit connects to interchangeable masks, simplifying inventory management for B2B clients.
Data Capture & Processing
The device records 23 biomarkers, but the headline metrics are:
| Biomarker | What It Indicates |
|---|---|
| VO₂ max | Maximal aerobic capacity; linked to mortality risk |
| Resting Metabolic Rate (RMR) | Basal calorie expenditure; informs diet planning |
| Metabolic Flexibility | Ability to shift fuel sources; marker of metabolic health |
Raw gas‑exchange data are streamed to an onboard microcontroller, then uploaded via Wi‑Fi to PNOĒ’s cloud platform. The software applies proprietary algorithms to convert breath data into the three headline metrics plus secondary insights (e.g., respiratory exchange ratio). Users receive a digital report with:
- Performance Scorecard – visual ranking of fitness level.
- Training Recommendations – intensity zones, interval suggestions.
- Nutrition Guidance – macronutrient ratios aligned with metabolic flexibility.
Hardware Design Considerations
The move to a self‑serve model demanded a redesign focused on durability and ease of use:
- Fewer Moving Parts: Reduces mechanical failure rates in high‑traffic environments.
- Hygiene‑First Architecture: Detachable mask eliminates cross‑contamination risk, a crucial factor for gyms and clinics.
- Power Management: Battery life supports multiple daily tests; the device can be docked for rapid charging during off‑hours.

Industry Impact: Disrupting Fitness, Wellness, and Healthcare
B2B Subscription Model
PNOĒ 2.0 is sold as a “Business in a Box” subscription ranging from $400 to over $1,000 per month. The fee bundles hardware, software, staff training, and marketing collateral. This model mirrors the SaaS approach that has transformed enterprise software, providing predictable revenue streams while lowering upfront capital expenditures for clients.
Competitive Landscape
While wearable heart‑rate monitors and VO₂ max estimators exist, few offer direct gas‑exchange measurements outside a lab. PNOĒ’s approach positions it ahead of:
- Wearable‑Only Solutions: Those rely on indirect estimations, which can be off by 10‑15% for VO₂ max.
- Traditional Lab Services: High cost, limited accessibility, and scheduling friction.
The device also aligns with the growing “digital health” trend, where data‑driven personalization is becoming a differentiator for premium fitness brands.
