What eMurmur does
eMurmur is a privately-held digital health company that develops AI-powered auscultation software for the automated detection, classification, and documentation of heart murmurs and lung sounds. Founded in Graz, Austria in 2014 by Andreas Schriefl (CEO) and Andreas Reinisch (CTO) and now headquartered in Ottawa, Canada, the company offers a hardware-agnostic platform that works with multiple FDA-cleared digital stethoscopes (Littmann, Riester, Thinklabs, Mintti Health, Muse Diagnostics, Lapsi Health). Its core product, eMurmur Heart AI, applies proprietary machine learning and signal processing to identify S1/S2 heart sounds, detect the presence or absence of abnormal murmurs, and generate hemodynamic insights from heart sound components, with sensitivity and specificity exceeding 85% in clinical validations at Johns Hopkins, CHEO, Duke, and other institutions. The eMurmur Lung AI module adds crackle and wheeze detection, and an eConsult feature plus Live Streaming enable specialist collaboration and remote auscultation over telehealth platforms.
The company monetizes through annual subscription licenses to its web and mobile applications and through API/platform access licensed to telehealth providers and digital stethoscope vendors. The AI software layer is FDA-cleared (three 510(k) clearances) and CE-marked (MDR Class IIa), and the company holds ISO 13485:2016 certification, HIPAA and GDPR compliance, and a proprietary labeled database of thousands of heart recordings paired with gold-standard echocardiogram diagnoses. eMurmur distributes via a direct B2B sales motion with onboarding and SOP support, a free 30-day trial, OEM integrations (3M Littmann, Riester, Lapsi Health), and channel partnerships (MobilDrTech in the US), serving healthcare providers in primary care, urgent care, telehealth, pediatrics, community pharmacy, and medical education.

eMurmur competitors and assessment
Company assessmentDirect peers
- Thinklabs: Thinklabs makes the Thinklabs One digital stethoscope, one of eMurmur's supported hardware partners. It is a peer in the digital auscultation ecosystem, though it competes more at the hardware layer while eMurmur provides the AI software layer.
- Eko Health: Eko Health is the leading AI-powered digital stethoscope company, offering FDA-cleared cardiac and pulmonary analysis directly embedded in its CORE stethoscope. It competes head-to-head with eMurmur in AI auscultation, although eMurmur differentiates by being hardware-agnostic and platform-licensed.
- StethoMe: StethoMe is a Poland-based digital health company that builds AI algorithms for heart and lung sound analysis, focused on home and pediatric use. It overlaps directly with eMurmur's lung AI and pediatric auscultation capabilities.
- TytoCare: TytoCare offers a remote examination platform with a connected stethoscope enabling telehealth auscultation. It competes with eMurmur in the remote auscultation segment of telehealth, though TytoCare sells bundled hardware while eMurmur is software-only.
Emerging players
- Butterfly Network: Butterfly Network provides AI-enabled handheld ultrasound (Butterfly iQ) with FDA-cleared diagnostic AI. It is comparable as an emerging AI medical imaging/diagnostics company targeting point-of-care use, though it focuses on ultrasound rather than auscultation.
- Sonavi Labs: Sonavi Labs develops an AI-enabled digital stethoscope (Feelix) with FDA clearance for respiratory and cardiac analysis. It is an emerging competitor to eMurmur in the AI auscultation space, focused on detecting pneumonia and other respiratory conditions.
- M3DICINE (Stethee): M3DICINE builds the Stethee, an AI-enabled stethoscope for cardiac and pulmonary analysis. It is comparable to eMurmur in providing AI auscultation insights, but ships its own bundled hardware rather than licensing software to third-party stethoscope vendors.
- iHealth Labs: iHealth Labs makes connected consumer and clinical health devices including digital stethoscopes. It is comparable as a connected health device manufacturer that could partner with or compete against eMurmur's auscultation AI software layer.
Broad incumbents
- Philips Healthcare: Philips offers telehealth, remote patient monitoring, and cardiac diagnostic solutions at scale. As a broad incumbent in connected cardiac care, it represents both a potential partner and a competitor to eMurmur's remote auscultation capabilities.
- 3M Littmann / Solventum: 3M Littmann (now Solventum) is the dominant incumbent in stethoscopes and a key partner via the Littmann Learning App. It is comparable as the largest hardware player whose stethoscopes eMurmur's AI integrates with, and as a potential competitor if it elects to develop in-house auscultation AI.
