What Nuubo does
Nuubo, legally Smart Solutions Technologies, S.L., is a Spanish medical device company founded in 2005 and headquartered in Madrid, with an R&D center in Valencia and manufacturing in Paterna. It develops a wireless, textile-based ambulatory electrocardiogram (aECG) monitoring system composed of three core products: the Nuubo30 garment (a seamless, adhesive-free vest with proprietary silver textile-electrode composite and elastic conductive tracks), the NuuboREC recording device (capturing up to 30 days of continuous ECG and accelerometer data), and the Nuubo Leonardo desktop software, which applies proprietary algorithms for automated arrhythmia detection (atrial fibrillation, tachycardia, bradycardia) and clinical reporting. A companion myNuubo iOS app supports patient symptom logging and device charging reminders.
The company serves hospitals, cardiology departments, and specialty clinics across Spain and Italy — including Hospital Vall d'Hebron, Hospital Clínic, Hospital Sant Joan de Déu, ASST Grande Ospedale Metropolitano Niguarda, and Ospedale Brotzu — with clinical validation anchored by approximately 3,500 enrolled patients and peer-reviewed publications in journals such as the International Journal of Cardiology and the European Heart Journal. Its clinical evidence base demonstrates materially superior AF detection rates (21.9% in cryptogenic stroke vs. 4.3–14.8% in comparator studies) and >90% patient compliance with 4.2/5 comfort ratings.
Nuubo operates a hardware-anchored medical device revenue model (sales of the vest, recorder, and software), with an emerging subscription/recurring component via the Leonardo analysis platform and patient-facing app. Pricing is not publicly disclosed; in the US, reimbursement is sought through Category III CPT codes determined at the Medicare Administrative Contractor level, contingent on FDA clearance currently in progress. The go-to-market is enterprise field sales to healthcare institutions and cardiology practices in CE-marked geographies, with explicit strategic intent to enter the US market using a €3.329M 2022 funding round (CDTI Innovación, Nuubo Investments, Fides Capital), a subsequent ~$3.8M CDTI INNVIERTE deployment in 2025, and ongoing public grants.

Nuubo product offering
Product offeringCore offering
Nuubo develops and manufactures a wireless, textile-based ambulatory ECG (aECG) monitoring system that combines a wearable electrode-embedded garment (Nuubo30), a portable recording device (NuuboREC/Minder) capturing up to 30 days of continuous ECG and accelerometer data, and proprietary arrhythmia detection and reporting software (Nuubo Leonardo). The system is prescribed by cardiologists and dispensed through hospitals and clinics for medium-to-long-term cardiac rhythm monitoring, particularly atrial fibrillation detection.
Product overview
Nuubo offers a comprehensive aECG (ambulatory electrocardiogram) monitoring system consisting of three integrated components: the Nuubo30 textile-based wearable vest with integrated ECG electrodes, the NuuboREC (Minder) portable recording device capturing up to 30 days of ECG and accelerometer data, and the Nuubo Leonardo desktop software for arrhythmia detection and clinical reporting. The system is complemented by the myNuubo patient mobile app for iOS. The portfolio enables non-invasive, wireless cardiac monitoring for medium to long-term periods, eliminating cables and adhesive electrodes while maintaining ECG quality comparable to traditional Holter monitors.

Nuubo competitors and assessment
Company assessmentEmerging players
- SmartCardia: SmartCardia offers a patch-based ECG monitoring solution with AI-powered arrhythmia detection. Comparable emerging peer to Nuubo in extended-wear ambulatory cardiac monitoring with similar hospital-channel GTM.
- Cardiac Insight: Cardiac Insight developed the Cardea SOLO wearable ECG sensor for AF and arrhythmia screening. Direct product peer in ambulatory single-use cardiac monitoring, focused on short-term diagnostic yield similar to Nuubo's use case.
- Empatica: Empatica develops wearable biosensors (EpiMonitor, Embrace) for continuous health monitoring including cardiac rhythm and seizure detection. Comparable in wearable-sensor approach and AI-driven health monitoring, though with different primary use cases.
- HeartBeam: HeartBeam is a smaller, early-stage cardiac diagnostics company developing a credit-card-sized 3D ECG device for ambulatory arrhythmia detection. Comparable emerging peer to Nuubo's outpatient cardiac monitoring focus, though with different form factor.
Direct peers
- Boston Scientific (Preventice Solutions): Boston Scientific acquired Preventice Solutions, which offers BodyGuardian Heart remote cardiac monitoring systems (patches and Holter-like devices). Direct competitor in ambulatory cardiac monitoring with similar hospital-channel GTM.
- AliveCor: AliveCor's KardiaMobile devices provide single-lead and six-lead ECG monitoring with AI-driven arrhythmia detection (KardiaAI). Directly competes with Nuubo in the ambulatory cardiac rhythm monitoring space, particularly for outpatient AF detection.
- iRhythm Technologies: iRhythm's Zio patch is a direct competitor in ambulatory ECG monitoring for arrhythmia detection, with similar extended-duration (14-day) cardiac monitoring and AI-based analysis. Most comparable company to Nuubo's wearable ECG system in product, target customer (cardiologists/hospitals), and business model.
- Philips (BioTel MCOT): Philips BioTel MCOT (Mobile Cardiac Outpatient Telemetry) is a direct competitor offering extended continuous ambulatory ECG monitoring with arrhythmia detection. Competes head-to-head with Nuubo for hospital and cardiology practice contracts.
Broad incumbents
- Philips Healthcare (Cardiac Monitoring): Philips' broader cardiac monitoring portfolio includes IntelliVue patient monitors and BioTel MCOT. As a large incumbent, Philips competes with Nuubo for hospital cardiac monitoring budgets across both inpatient telemetry and ambulatory monitoring segments.
- GE Healthcare (MUSE Cardiology): GE Healthcare provides broad cardiology monitoring and ECG management solutions including MUSE and related hospital telemetry/monitoring products. While not a wearable competitor, its dominant installed base in hospital cardiology creates competitive context for ambulatory monitoring expansion.
