What Nyxoah does
Nyxoah SA is a Belgian medical technology company that develops and commercializes the Genio system, a bilateral hypoglossal nerve stimulation (HGNS) therapy for moderate-to-severe obstructive sleep apnea (OSA) in adults who have failed, refused, or cannot tolerate CPAP. The system consists of a battery-free, leadless implantable neurostimulator placed under the chin in a single-incision outpatient procedure, a disposable adhesive sleep wearable that powers the implant nightly, and a patient-facing smartphone app for therapy control and usage tracking. Genio received CE Mark in 2019 and FDA Premarket Approval in August 2025, supported by the DREAM pivotal trial demonstrating a 63.5% AHI responder rate and 70.8% median AHI reduction.
Nyxoah operates a direct enterprise sales model, with a 40-representative US field sales force targeting hospitals and ambulatory surgical centers, complemented by reference accounts in the Netherlands (OLVG West, Zuyderland) and the Middle East (Saudi German Hospital Dubai). The company sells the implantable device and recurring disposable patch consumables, reimbursed under CPT code 64568 with Medicare hospital outpatient payment of approximately $45,000 and ASC payment of $42,373 under the CY2026 rule. Genio is the company's sole commercial product; pricing is not publicly disclosed but the company reports 100% prior-authorization approval on reviewed commercial payer submissions.

The company has funded US and international commercialization through multiple public offerings and a €37.5M EIB loan facility, with €36-40M of FY2026 worldwide net revenue guided by management. Strategic investors Cochlear and ResMed participated in a $77M November 2025 financing, and a $110M capital raise (BofA-led $95M equity plus $15M EIB tranche) closed in June 2026. The current CEO, Olivier Taelman, is leading a planned transition to a US-based CEO as the company enters its next US-driven growth phase.

Nyxoah product offering
Product offeringCore offering
Nyxoah develops and commercializes the Genio system, a leadless, battery-free bilateral hypoglossal nerve stimulation (HGNS) therapy implant for treating moderate to severe obstructive sleep apnea (OSA) in adult patients who have failed, refused, or cannot tolerate CPAP therapy. The system comprises an implantable stimulator placed under the chin in a single-incision outpatient procedure, a disposable external wearable adhesive patch that powers the implant nightly, and a patient-facing smartphone app for therapy control and usage tracking.
Product overview
Nyxoah is a medical technology company focused on treating obstructive sleep apnea (OSA). The company's sole product is the Genio System, a comprehensive hypoglossal nerve stimulation therapy consisting of three integrated components: (1) a battery-free implantable neurostimulator that is inserted under the chin in a single-incision outpatient procedure, (2) a disposable sleep wearable patch with external activation chip that powers the implant nightly, and (3) a smartphone app that allows patients to control stimulation within predefined settings and track device usage. Genio received CE Mark approval in 2019 and FDA PMA approval in August 2025 for adult patients with moderate to severe OSA (AHI 15-65) who have not tolerated, failed, or refused CPAP therapy. The therapy works by bilateral stimulation of the hypoglossal nerve to contract tongue muscles and maintain airway patency during sleep.

Nyxoah competitors and assessment
Company assessmentBroad incumbents
- Fisher & Paykel Healthcare:
- ResMed: ResMed is the global leader in sleep-disordered breathing and CPAP therapy. While focused on PAP rather than HGNS, ResMed is a Nyxoah investor and serves the same OSA patient pool, making it both a complementary incumbent and a strategic partner with deep distribution in sleep clinics.
- Koninklijke Philips: Philips is a major player in sleep and respiratory care through its DreamStation and other CPAP/APAP product lines. It operates broadly in the same OSA therapy market, overlapping with Nyxoah on patient population but not on the implantable HGNS modality.
Direct peers
- Inspire Medical Systems: Inspire Medical Systems is the leading U.S. provider of hypoglossal nerve stimulation therapy for OSA with its Inspire UAS system. It is Nyxoah's most direct competitor, addressing the same CPAP-intolerant patient population with an implantable neurostimulator and has multi-year incumbency advantages in U.S. payer coverage and surgeon networks.
