Ellipsis Health

Ellipsis Health is a healthcare AI company that has established the human voice as a vital sign for mental health, using clinically validated vocal-biomarker technology, natural language processing, and acoustic models to identify, measure, and monitor the severity of depression and anxiety from short samples of natural speech. Its flagship product, Sage, is an emotionally intelligent, agentic AI care manager that conducts 24/7 patient-engagement calls for health plans, health systems, specialty care, and pharma, handling program enrollment, benefits verification, clinical assessments and surveys, and care coordination. Sage is powered by Ellipsis' patented Empathy Engine, trained on millions of live clinical patient calls, and runs on HIPAA and SOC 2 Type 2 compliant infrastructure. Ellipsis Health integrates with health plans and systems such as Cigna, and exposes a private partner API (used by partners like Augmedix) rather than a public developer platform. The company is backed by Khosla Ventures, Salesforce Ventures, and CVS Health Ventures.
