Cenas

What Cenas does

Cenas is a Swiss private network of specialized sleep medicine centers headquartered in Chêne-Bourg (Greater Geneva), operating as Cenas Medical SA with a second location forthcoming in Bulle (Canton of Fribourg). Its core offering is the full diagnostic and therapeutic pathway for sleep disorders, including polysomnography with real-time video/audio surveillance, home-based respiratory polygraphy, nocturnal oximetry, actigraphy, and daytime tests (MSLT). Therapeutic services span CPAP equipment fitting and follow-up, cognitive behavioral therapy for insomnia (CBT-I), luminotherapy and chronotherapy, and sophrology. Technologically, the centers rely on accredited diagnostic equipment rather than proprietary software; the only consumer digital asset is the Lausanne NoSAS Score screening app, co-developed with agency BeFine in 2017.

The business model blends insurance-reimbursable medical services with hardware sales. Consultations and sleep examinations are billed under Swiss basic health insurance (LAMal) per session, requiring physician prescription. CPAP devices and annual consumables represent a recurring hardware revenue stream with associated device maintenance and replacement cycles. Customer acquisition runs primarily through physician referral: treating physicians submit evaluation requests validated by Cenas' medical staff before scheduling, with a secure online Espace Médecin portal serving the referring-physician channel. Direct patient access is permitted but routed back to primary physicians for proper care initiation.

The entity is privately held with no external funding rounds disclosed, operating through three Swiss corporate vehicles (Cenas Medical SA, CISG SA, Centre du sommeil Bulle Cenas SA) under Geneva and Fribourg jurisdictions. It is officially certified by the Swiss Society for Sleep Research, Sleep Medicine and Chronobiology (SSSSC) and has run category-defining public events such as the first Swiss Sleep Day in 2017 in partnership with CHUV. Its expansion strategy is incremental and geographically constrained to French-speaking Switzerland, with headcount in the 11–50 range.

Products and services

• Polysomnography (Polysomnographie) Comprehensive overnight sleep recording that monitors all sleep parameters (brain activity, eye movements, muscle tone, heart rate, breathing patterns, oxygen levels) with real-time video and audio surveillance for complete sleep architecture and hypnogram analysis; for patients with suspected sleep disorders referred by physicians.
• Respiratory Polygraphy (Polygraphie ventilatoire) Home-based respiratory polygraphy examination that detects sleep-related breathing disorders such as sleep apnea by monitoring breathing patterns, airflow, and oxygen saturation during sleep; for patients referred for suspected sleep-disordered breathing.
• Nocturnal Oximetry (Oxymétrie) Nocturnal pulse-oximetry recording that measures blood oxygen saturation throughout the night to identify breathing-related sleep disorders; for patients with suspected nocturnal hypoxemia.
• Actigraphy (Actimétrie) Wrist-worn activity monitoring that tracks sleep-wake rhythms over several weeks to assess circadian patterns and sleep quality; for patients with suspected circadian rhythm disorders or hypersomnia.
• Daytime Sleep Tests (Tests diurnes) Daytime evaluations including the Multiple Sleep Latency Test (MSLT) that measure daytime sleepiness and detect disorders affecting wakefulness maintenance, such as narcolepsy and idiopathic hypersomnia.
• Sleep Diary (Agenda du sommeil) Self-reported sleep diary that patients complete to track sleep patterns, duration, quality, and disturbances over time as a complementary diagnostic and therapeutic tool.
• CPAP/PPC Therapy (Pression Positive Continue) CPAP therapy consisting of a generator, tubing, and mask (nasal, nasal pillow, or full-face) that delivers air pressure to keep airways open during sleep, plus device calibration, repair, and consumable replacement services; for patients diagnosed with obstructive sleep apnea.
• Cognitive Behavioral Therapy for Insomnia (CBT-I / TCC-I) Structured cognitive behavioral therapy program for chronic insomnia delivered over 5 to 8 one-hour sessions; the standard long-term, non-pharmacological treatment for insomnia provided to patients referred to Cenas.
• Luminotherapy and Chronotherapy Light therapy treatment involving controlled exposure to white light of specific intensity and duration to correct circadian rhythm disorders and seasonal affective disorder, complemented by chronotherapy for gradual sleep schedule adjustment.
• Sophrology Relaxation-based therapy combining physical relaxation techniques and breathing exercises to help patients release tension and achieve restful sleep.
• Physician Member Portal (Espace Médecin) Secure online member portal reserved for validated healthcare professionals providing access to patient resources, referral forms, sleep documentation, continuing-education content, and a dedicated FAQ; requires account activation after Cenas validation.

Scale indicators4 records

Recent moves7 records

Expansion highlights5 records

Emerging players

• Withings: Consumer health technology company offering connected sleep tracking mats and watches that measure sleep cycles, heart rate, and snoring. Comparable to Cenas on the consumer sleep monitoring and awareness side, providing a low-cost alternative to in-clinic actigraphy.
• Dreem: Paris-based sleep technology company combining a wearable headband with software for sleep tracking and behavioral coaching. It is an emerging player in the consumer sleep health space, overlapping with Cenas's actigraphy-based sleep monitoring and insomnia therapy offerings.
• Big Health (Sleepio): Digital therapeutics company offering Sleepio, a clinically validated digital CBT-I program for insomnia. It represents an emerging, scalable, home-based alternative to Cenas's in-person CBT-I service and could shift physician referral patterns toward non-clinic options over time.

Broad incumbents

• Resmed: Global leader in CPAP devices and sleep-disordered-breathing solutions, including connected health platforms. While primarily a device and software company, Resmed overlaps with Cenas in CPAP therapy delivery and is increasingly moving into integrated care services that could eventually compete with clinic-based providers.
• Schlafzentrum Hirslanden: Hirslanden, Switzerland's largest private hospital group, operates accredited sleep medicine centers across multiple cantons. It is comparable to Cenas as a private, multi-site Swiss sleep medicine provider, though it competes across a much wider specialty portfolio.
• SomnoMed: Global medical device company specializing in oral appliances for obstructive sleep apnea and snoring. It is a broad incumbent in the non-CPAP sleep apnea treatment space, offering an alternative care pathway that competes for the same patient population Cenas treats with CPAP.
• Philips Sleep & Respiratory: Philips' sleep and respiratory business supplies CPAP devices, masks, and digital sleep platforms globally. It is a broad incumbent in the equipment side of Cenas's offering, with growing software-enabled patient management capabilities that could encroach on clinic-led therapy management.

Direct peers

• Unité de Médecine du Sommeil - Hôpitaux Universitaires de Genève (HUG): HUG's sleep medicine unit provides diagnostic and therapeutic services for sleep disorders within the Geneva public hospital system. It directly competes with Cenas Chêne-Bourg for physician referrals and patient volume in the Geneva catchment area.
• Centre de Médecine du Sommeil - CHUV: The sleep medicine center at Lausanne University Hospital (CHUV) offers polysomnography, CPAP, and specialist consultations across the full range of sleep disorders. It is both a direct clinical peer to Cenas in French-speaking Switzerland and an existing research partner, competing for complex sleep cases in the region.

Others

• Hôpital de La Tour: Private hospital in Geneva with which Cenas has announced a registration center partnership. It is a partner rather than a competitor, but as a private hospital offering a broad range of specialties, it represents the kind of institutional channel Cenas could deepen or replicate with other hospitals.
