Vital Audio

What Vital Audio does

Vital Audio Inc is a Brooklyn, NY-based private company founded in 2022 that develops AI-powered voice biomarker software for clinical-grade health monitoring. Its sole product, the Sonometrik platform, processes short voice samples captured through a standard smartphone microphone to extract physiological metrics including heart rate, heart rate variability (HRV), rhythm, and respiratory metrics, eliminating the need for wearables or specialized hardware. The technology is positioned as a novel AI method architecture within the audio/speech modality, targeting healthcare consumers who want accessible real-time health monitoring using their existing phone.

The company operates at very early stage scale, with 1-10 employees and no publicly disclosed revenue, pricing, customer logos, partnerships, or regulatory clearances. To date it has raised approximately $3.22M across three capital events: a $120K Techstars seed in September 2023, a $3M round led by Flybridge in August 2024, and a $100K TechCrunch-related tranche in December 2025. Ownership structure, management team details, certifications, and operating geographies are not disclosed in available source data. The value proposition rests on hardware-free deployment and the underlying AI's ability to translate acoustic voice features into physiological signals, though no clinical validation evidence, third-party benchmarks, or FDA submissions are documented.

Core offering

Vital Audio develops the Sonometrik platform, an AI-powered software product that captures heart rate, heart rate variability, rhythm, and respiratory metrics from short voice samples captured through a standard smartphone. The platform turns any phone into a real-time health monitoring tool, removing the need for wearables, contact sensors, or specialized hardware. The company markets this as novel digital voice biomarker software intended to produce clinical-grade insights from voice clips during phone calls.

Product overview

Vital Audio Inc offers a single unified product called Sonometrik, an AI-powered software platform that captures health metrics (heart rate, heart rate variability, rhythm, and respiratory metrics) through voice samples. The platform transforms any smartphone into a real-time health monitoring tool, eliminating the need for wearables or new hardware.

Direct peers

• Sonde Health: Voice biomarker platform that derives health and cognitive indicators from voice samples. Most direct comparable: same AI-voice-to-health-metric thesis, targets enterprise health and pharma partners, similar hardware-free approach.
• Canary Speech: Develops voice biomarker technology to detect disease and mental health conditions from vocal features. Closely comparable to Vital Audio in using short voice samples to produce clinical-grade health signals for partners and clinicians.
• Ellipsis Health: AI-driven voice biomarker company focused on mental health (depression/anxiety) detection from speech. Same voice-to-health-metric technology approach, with a narrower (mental health) vertical.
• Kintsugi: Voice biomarker startup detecting mental health conditions from short voice clips. Directly comparable technology stack and product form factor (short voice sample API), differing only in clinical focus.
• Winterlight Labs: Uses voice analysis and AI to detect cognitive and neurological conditions from speech samples. Highly comparable voice-biomarker methodology, with focus on CNS indications rather than cardiac/respiratory vitals.

Emerging players

• Cardio Diagnostics: AI-driven cardiovascular diagnostics company. Comparable in delivering AI-derived cardiac insights, but uses epigenetic and blood-based biomarkers rather than voice — a partial overlap with Vital Audio's cardiac monitoring ambition.
• Biofourmis: Remote patient monitoring and digital therapeutics company focused on cardiac and chronic condition management. Comparable end market (continuous cardiac/respiratory monitoring) but uses wearable sensors instead of voice biomarkers.

Broad incumbents

• Apple (Health / Apple Watch): Apple Watch and Apple Health embed heart rate, HRV, rhythm, and respiratory sensing into a mass-market consumer platform. Represents both the largest incumbent threat and a potential integration/acquisition counterparty for Vital Audio.
• Fitbit (Google): Wearable platform under Google with established heart rate, SpO2, and respiratory features and a large consumer health user base. Comparable end-user outcome (continuous vitals) but via hardware rather than voice software.
• Google Health: Broader Google effort to build consumer and clinical health products across hardware, AI, and software. Adjacent incumbent that could bundle voice-based vitals into Android or Fitbit, displacing standalone players.
