What HD Medical does

HD Medical (also operating as HD Medical Group) is a privately held medical device company headquartered in Silicon Valley, California, that develops AI-marketed cardiovascular diagnostics hardware for point-of-care use. Its flagship product, the FDA-cleared Class II HD Steth, is an intelligent stethoscope that integrates triple-electrode single-lead ECG, phonocardiography (PCG), and lung sound detection into a single Bluetooth-enabled device, paired with a companion mobile application (Android and iOS) that displays simultaneous heart sound and ECG waveforms and supports recording, playback, and EHR data transfer. The company also has a second device, HealthyU (a personalized home health monitoring device currently in FDA regulatory review), positioning it for eventual expansion into consumer and remote patient monitoring.

The company's technology stack relies on patented active noise cancellation and smart amplification, an FDA-cleared architecture spanning three product classification codes (DQD Electronic Stethoscope, DQC Phonocardiograph, DPS ECG/Cardiac Monitor), and a rechargeable Panasonic 18650 lithium-ion battery system providing up to 8 hours of continuous use. Manufacturing and component supply are supported by a strategic investor relationship with Analog Devices (NASDAQ: ADI), a semiconductor specialist in data conversion and signal processing, which holds a board observer seat. HD Medical has obtained multi-region regulatory clearances including ISO 13485:2016, ISO 27001, CE (IEC 60601-2-27), SFDA (Saudi Arabia), and CDSCO (India), and operates a dedicated India subsidiary led by a country Director.

HD Medical's go-to-market is a direct enterprise field sales motion targeting primary care physicians, pediatricians, cardiologists, urgent care and emergency medicine providers, and hospital/post-operative care settings, with clinical endorsements from physicians at UCSF, Stanford Byers Center for Biodesign, and Northwestern Medicine serving as credibility anchors. Pricing is quote-based and not publicly disclosed. Revenue mechanics combine one-time hardware sales (HD Steth device) with a recurring mobile app component (HD Steth App) and professional services for EHR integration, supplemented by recurring accessory sales (diaphragms, batteries, eartips, chargers, HD Speaker). The company has no publicly disclosed funding history beyond a 2019 MedTech Innovator program participation and no disclosed revenue, operating with a small 11–50 employee headcount.

Core offering

HD Medical develops and sells FDA-cleared Class II intelligent stethoscope (HD Steth) that integrates phonocardiography, single-lead ECG with triple gold-plated electrodes, and lung sound detection in a single Bluetooth-enabled device. The hardware is paired with a companion mobile app that displays simultaneous heart sound and ECG waveforms, enables recording and data management, and supports EHR system integration for healthcare providers.

Product overview

HD Medical offers a portfolio of AI-powered cardiovascular diagnostics devices centered around two main hardware products: HD Steth (FDA cleared Class II diagnostic device) and HealthyU (FDA pending). HD Steth is an intelligent stethoscope combining phonocardiography, triple-electrode ECG, and lung sound detection, paired with a Bluetooth companion app for simultaneous waveform visualization, recording, and EHR integration. HealthyU is a home health monitoring device. The ecosystem includes official accessories (diaphragm, battery, charger, eartips, speaker) and software app for Android/iOS. Together, the products enable point-of-care cardiac screening, monitoring, and diagnostic support for clinicians.

Direct peers

• AliveCor: AliveCor (KardiaMobile) sells FDA-cleared personal ECG devices and a clinician platform for cardiac arrhythmia detection. It overlaps directly with HD Steth's ECG integration, FDA-cleared cardiac monitoring positioning, and primary-care screening value proposition, although its form factor is single-purpose rather than stethoscope-based.
• iRhythm Technologies: iRhythm's Zio long-term cardiac monitoring patch competes with HD Steth in ambulatory cardiac monitoring and arrhythmia detection. It addresses the same cardiologist customer base but with multi-day continuous monitoring rather than point-of-care auscultation plus single-lead ECG.
• Eko Health: Eko Health is the most direct competitor, offering FDA-cleared smart stethoscopes (CORE, CORE 500) with embedded AI for cardiac and pulmonary analysis, paired with telehealth and EHR integration. It targets the same primary care, cardiology, and hospital customer base as HD Medical with a directly overlapping product category.

Emerging players

• Steth IO: Steth IO develops smartphone-based smart stethoscopes for cardiac and pulmonary auscultation. It is comparable as a smaller, niche-focused entrant in the connected stethoscope category, though its commercial scale is significantly smaller than HD Medical's.
• Aevice Health: Aevice Health develops a wearable stethoscope for continuous remote cardiopulmonary monitoring in chronic disease management. It overlaps with HD Medical's HD Steth and (pending) HealthyU on connected auscultation and home-based cardiac/respiratory monitoring.
• Rijuven: Rijuven builds connected cardiac screening devices (CardioSleeve) intended for primary care and pediatric screening — directly overlapping with HD Medical's primary care and pediatrician customer segments and value proposition around evidence-based cardiac screening at the point of care.

Broad incumbents

• TytoCare: TytoCare offers a multi-modality remote examination platform (stethoscope, otoscope, thermometer, camera) used for telehealth visits. It overlaps with HD Medical's remote and point-of-care auscultation use case but addresses a broader multi-organ examination workflow and competes mainly in telehealth rather than in-clinic screening.
• Philips (Cardiac Monitoring / eICU): Philips offers a portfolio of cardiac monitoring solutions (telemetry, IntelliVue, wearable biosensors) sold to the same hospital and cardiology customers. It competes less on smart stethoscope form factor and more on integrated inpatient and remote monitoring workflows.
• 3M Littmann CORE: 3M's Littmann CORE is an electronic stethoscope with amplification, Bluetooth, and AI-assisted auscultation, sold through the dominant Littmann clinical brand. It competes with HD Steth in the same core auscultation use case but is part of 3M's much broader medical portfolio and enjoys established distribution across nearly every U.S. hospital.

Others

• Withings (BPM Core / ScanWatch): Withings produces connected consumer health devices including a stethoscope-equipped BPM Core and ECG-enabled ScanWatch. It is adjacent rather than directly competing — consumer-grade positioning, no clinician-focused sales motion — but its ECG and cardiac rhythm features overlap thematically with HD Medical's roadmap.
