Company Overview

Clairaudience Co., Ltd.

Clairaudience is a South Korean medical device company developing MUST, a multimodal platform for cardiovascular screening and follow-up. MUST combines heart-sound and finger pulse-wave measurements with AI models designed to estimate selected echocardiographic indicators and support referral decisions. The company is pursuing clinical validation and Korean regulatory approval, with a roadmap spanning clinician software, patient education and home monitoring.

Technology Details

Synchronized Heart-Sound and Pulse-Wave Acquisition

MUST captures chest heart sounds and finger pulse waves simultaneously in an approximately 20-second measurement. Clairaudience reports 2,103 multimodal datasets from 1,886 participants, including biosignals, echocardiography and medical records.

Research Evaluation of Valve Screening

The IR reports external-test AUROCs of 0.90 for aortic regurgitation, 0.89 for aortic stenosis, 0.79 for tricuspid regurgitation and 0.68 for mitral regurgitation, based on 118 measurements. These are endpoint-specific screening results for moderate-or-greater disease; prospective clinical validation is ongoing.

DR. BEN Personalized Education

DR. BEN is a publicly listed app offering clinician-led education videos, quizzes, health records and AI-based content recommendations. The IR describes a plan to tailor education using MUST findings, diagnoses and medication records.

Problem & Unmet Needs

Access to Specialist Cardiac Assessment

Echocardiography requires dedicated equipment and trained operators, which can limit timely assessment in some primary care settings. MUST is being developed as a short, accessible screening step to help identify patients who may need further cardiac evaluation.

Gaps Between Follow-Up Visits

Periodic clinic visits provide only snapshots of chronic cardiovascular conditions. Clairaudience's planned monitoring workflow combines repeat biosignal recordings, patient records and education to support more structured follow-up.

Market Trends

AI-Assisted Cardiovascular Assessment

AI-enabled digital stethoscopes and automated echocardiography software are being deployed to support frontline assessment and reporting. These products illustrate a commercial market for AI-assisted cardiac workflows, with clinical validation and clinician review central to adoption.

Clinic-Based SaaS Opportunity

Clairaudience estimates a South Korean clinic-based SaaS opportunity of approximately USD 33.85 million annually, based on 36,685 clinics and a monthly fee of approximately USD 76.92. Its planning model values the narrower serviceable segment at approximately USD 10.31 million per year.

Competitive Landscape

Digital Auscultation and Automated Echocardiography

Eko's SENSORA combines ECG and heart-sound analysis for cardiac screening, while Us2.ai automates measurements from ultrasound studies. Clairaudience is developing a PCG-plus-PPG approach to estimate selected echo-related indicators from short non-ultrasound recordings.
