CSD Labs

What CSD Labs does

CSD Labs, doing business as eMurmur, is an Austria-based medical AI company (founded 2015, headquartered in Graz) operating through a dual-entity structure of CSD Labs International Inc. (US) and CSD Labs GmbH (Germany). The company develops FDA-cleared, CE-marked, ISO 13485:2016-certified AI software that listens to, records, streams, and analyzes heart and lung sounds, transforming passive stethoscope monitoring into active clinical decision support. Its core offerings are eMurmur Heart AI for automated detection of abnormal heart murmurs and eMurmur Lung AI for lung sound crackle detection, both designed to be hardware-agnostic and software-neutral so they can run across multiple digital stethoscope brands and integrate with third-party platforms.

The platform serves clinicians and care teams, telehealth providers, stethoscope vendors (via OEM/embedded licensing), home health solution providers, and patients at home (asynchronous remote auscultation). It is complemented by the Littmann Learning App, an educational sub-brand provided in partnership with Littmann (3M) and trusted by 100,000+ trainees mastering cardiac and pulmonary auscultation.

CSD Labs monetizes through a hybrid GTM: a product-led, self-serve free trial on its website for individual clinicians and smaller practices, paired with an enterprise/B2B motion targeting stethoscope manufacturers, telehealth platforms, and home health solution providers for OEM licensing and integrations. The company holds HIPAA and GDPR compliance, received FDA clearance for interoperable AI murmur detection in December 2025, and operates without material disclosed external funding beyond an early EISMEA grant and Creative Destruction Lab participation, suggesting a lean, capital-efficient profile.

Direct peers

• Eko Health: Eko Health is a direct competitor offering AI-powered digital stethoscopes (CORE 500) with FDA-cleared cardiac AI algorithms for murmur and atrial fibrillation detection. Both companies target the same clinicians and telehealth use cases, though Eko bundles hardware + software while eMurmur is software-agnostic.
• TytoCare: TytoCare offers a telehealth platform with a remote examination device that includes a digital stethoscope. Competes directly with eMurmur's telehealth integration use case by enabling remote auscultation during virtual visits, though TytoCare sells an integrated hardware kit rather than standalone AI software.
• StethoMe: StethoMe provides AI-based lung and heart sound analysis for home use and pediatric telehealth, with both a smart stethoscope and AI auscultation software. Comparable to eMurmur in the AI auscultation category, particularly for remote patient monitoring and home health deployments.

Emerging players

• Thinklabs One: Thinklabs makes high-fidelity digital stethoscopes often used in telehealth and AI integration scenarios. Comparable as a digital stethoscope hardware partner that could integrate eMurmur's AI software.
• HD Medical Healthiest: HD Medical integrates AI auscultation with digital stethoscopes for cardiac screening. Comparable to eMurmur in combining stethoscope hardware with AI cardiac analysis, though HD Medical also bundles its own hardware rather than being purely software-agnostic.
• AusculSciences: AusculSciences develops AI-driven cardiac and pulmonary auscultation analytics for clinical decision support. Overlaps with eMurmur's core AI auscultation capabilities but is more focused on enterprise hospital deployment.

Broad incumbents

• Philips (Cardiology & Telehealth): Philips offers telehealth solutions, remote patient monitoring, and cardiology diagnostic tools that overlap with eMurmur's use cases. As a large incumbent, Philips could integrate its own auscultation AI or compete in telehealth-enabled cardiac screening.
• 3M Littmann: 3M Littmann is the dominant stethoscope brand and a current partner of eMurmur via the Littmann Learning App. As an incumbent, Littmann is both a key GTM channel and a potential competitive threat if it develops proprietary auscultation AI for its stethoscope line.
