Diametos GmbH

What Diametos GmbH does

Diametos GmbH is a Potsdam-based digital health company developing medically certified software for the diagnosis of sleep-related breathing disorders, founded in 2014 on more than a decade of prior academic and clinical research in acoustic sleep analysis. The company sells two products: Snorefox, a smartphone app that uses the device's built-in microphone to perform overnight audio recording and automated obstructive sleep apnea (OSA) risk screening with a traffic-light display and integrated doctor finder; and Somnofox, positioned as the world's first and only medical device for the anatomical phenotyping of snoring causes, sold to sleep surgeons, ENT specialists, and sleep medicine clinics for use in clinical diagnostic workflows. The underlying technology is proprietary acoustic AI — patented signal processing and machine learning algorithms that detect breathing patterns, apnea events, and snoring excitation locations from audio data, with granted patents in Germany, Europe, the US, China, and Japan.

The company operates a dual go-to-market. Snorefox is distributed directly to consumers via the iOS App Store and Google Play using a product-led growth motion (no sensors or wearables required), and several German statutory health insurance companies (GKV) cover the cost of usage, creating a B2B2C reimbursement dynamic. Somnofox is sold into clinical practice via direct sales, generating one-time license revenue for anatomical phenotyping data used in surgical treatment planning. The company is privately held, backed by venture capital from business angels and international industry partners, and supplemented by research funding from the Investitionsbank des Landes Brandenburg (ILB) and EU structural funds (EFRE/ESF+). Pricing is not publicly disclosed, and revenue figures have not been released.

Headcount is reported at 1–10 employees, led by Managing Director and co-founder Dr. Christoph Janott, who combines academic sleep/audio research with technology company management experience. Strategic research partners include TU Munich, Fraunhofer Institute, University Hospital Mannheim, University of Duisburg-Essen, OLVG (Netherlands), and Harvard Medical School. Operating geography is DACH-focused, with patent filings indicating longer-term intent toward US and Asian markets.

Core offering

Diametos develops medically certified acoustic AI software for sleep-related breathing disorder diagnostics. Its flagship consumer product Snorefox is a smartphone app that uses the phone's built-in microphone to record overnight audio and screen for obstructive sleep apnea risk. Somnofox is the world's first and only medical device for anatomical phenotyping of snoring causes, used by sleep surgeons and ENT specialists in clinical diagnostic workflows.

Product overview

Diametos offers two medical software products for sleep-related breathing disorder diagnostics. Snorefox is a consumer-facing smartphone app providing low-threshold OSA risk screening through acoustic analysis of nighttime audio recordings. Somnofox is a clinical medical device for sleep physicians that provides anatomical phenotyping of snoring sounds to support treatment planning. Both products work with standard smartphones without requiring additional sensors or wearables.

Differentiator

Problem solved

Functional benefit

Brands

• Snorefox: A medical app for sleep apnea risk screening, accessible and easy to use. No sensors or wearables required, using the smartphone's built-in microphone for nighttime audio recording. Provides acoustic analysis of breathing patterns, pauses, and snoring sounds, displayed as a traffic light risk indicator.
• Somnofox

Products and services

• Snorefox Medically certified smartphone app for obstructive sleep apnea (OSA) risk screening that uses the phone's built-in microphone to record overnight audio, performs acoustic AI analysis to detect breathing patterns, pauses, and snoring sounds, and displays a traffic-light risk indicator with an integrated doctor finder. Targeted at individual consumers; costs are reimbursed by several statutory German health insurers.
• Somnofox World's first and only medical device for the acoustic phenotyping of snoring, used by physicians in clinical diagnostic workflows. Provides anatomical analysis of snoring causes (pharyngeal passage phenotyping) to support sleep surgeons in individualized treatment planning. Sold to sleep medicine practices, ENT clinics, and sleep surgery centers.

Quantifiable outcome

• Up to 18% reduction in direct healthcare costs per patient over 10 years through early OSA screening
• +3 more outcomes

Expansion highlights5 records

Direct peers

• Withings: Withings sells Withings Sleep Analyzer, a contactless under-mattress sleep tracking device that performs acoustic and biometric analysis of sleep, including sleep apnea detection. Both Diametos and Withings target consumer sleep apnea screening through audio-based technology and pursue clinical validation, making Withings the most directly comparable competitor.
• Itamar Medical (ZOLL Itamar): Itamar Medical (acquired by ZOLL) developed WatchPAT, a home sleep apnea testing (HSAT) device using peripheral arterial tone. WatchPAT is a direct clinical competitor to Diametos's diagnostic ambitions, serving sleep physicians with validated at-home OSA detection, though using a different physiological signal modality.
• Nox Medical: Nox Medical manufactures professional HSAT and PSG devices (Nox T3, Nox A1) widely used in clinical sleep medicine. Diametos's Somnofox competes for the same physician clinical workflow, though Nox uses full polysomnography hardware rather than acoustic-only analysis.
• Cleveland Medical Devices (CleveMed): CleveMed develops home sleep testing devices and software (SleepView) for clinical sleep apnea diagnosis. CleveMed serves the same physician and clinical diagnostic workflow as Somnofox, providing an established HSAT alternative with different sensor technology.

Broad incumbents

• ResMed: ResMed is the global leader in sleep apnea therapy (CPAP/APAP) and has expanded into connected health software (myAir, AirView) and consumer-facing screening tools. Diametos's products sit upstream of ResMed's therapy business, and ResMed's broad installed base and reimbursement contracts represent both a major channel partner and a potential competitive threat.
• Apple: Apple Watch's sleep apnea notification feature (FDA-cleared in 2024) and Apple's broader Health ecosystem position it as a major consumer sleep health platform. Apple's scale, distribution, and brand make it both a competitive threat to Snorefox and a potential partnership channel for Diametos's acoustic AI technology.

Emerging players

• Dreem: Dreem builds EEG-based sleep monitoring headbands for consumer sleep tracking and clinical research. While Dreem uses EEG rather than acoustic analysis, both companies target the same convergence of consumer sleep technology and clinical sleep medicine applications.
• Oura: Oura produces a smart ring with sleep tracking features including sleep staging and respiratory disturbance detection. Oura competes with Snorefox for consumer sleep health attention and has begun moving into medical-grade features, though without Diametos's medical device certification for OSA screening.
• SleepScore Labs: SleepScore Labs offers consumer and enterprise sleep improvement solutions using contactless sleep monitoring and partnerships with mattress/bedding brands. They overlap with Diametos in consumer sleep diagnostics but lack the medical device certification and anatomical phenotyping capabilities.

Regional players

• Beurer: Beurer is a German health and wellness electronics company offering sleep tracking devices (SE 80 SleepExpert) using contactless sensor technology. As a regional DACH player with established retail channels, Beurer is a comparable German consumer sleep health device competitor.
