Ellipsis Health

Ellipsis Health

Ellipsis Health is a healthcare AI company whose product, Sage, is a voice-based AI care manager for patients with complex behavioral, physical, and social needs. Ellipsis Health pairs patented vocal-biomarker technology with an "Empathy Engine" trained on millions of recorded clinical patient calls, so Sage can detect emotional state and adjust tone during outreach, triage, care coordination, and disease management. Aimed at health plans and at-risk providers, Ellipsis Health positions Sage as added staffing capacity rather than a chatbot, handling enrollment and follow-up calls that human care teams cannot reach at scale. The company is based in San Francisco.

Production credibility: Founded in 2017 by CEO Mainul Mondal (a former Rockefeller Fellow at the Public Health Institute who also worked on a Stanford Freeman Spogli Institute initiative). Ellipsis Health has raised approximately $75M total, headlined by a $45M round announced June 2025 co-led by Salesforce, Khosla Ventures, and CVS Health Ventures, with Mitsui Global Investment, AME Cloud Ventures, and E12 also participating; an earlier $26M round closed in 2021. Its vocal-biomarker work is patented and trained on millions of live clinical calls. The company reports (its own figures, not independently audited) roughly a 60% reduction in administrative tasks, ~6x faster program enrollment, and ~4x ROI for deployments; specific health-plan customers are described as 'top-tier' but not publicly named.

Key Features

• Sage AI care manager places and takes outbound/inbound patient calls end-to-end
• Patented vocal-biomarker models infer emotional and mental-health signals from speech
• "Empathy Engine" adapts tone and pacing to each patient's state mid-conversation
• Covers triage, care coordination, disease management, and program enrollment
• Targets high-cost, complex patients with combined physical, behavioral, and social needs
• Built for health plans and value-based / at-risk provider groups
• Designed to expand care-team staffing capacity instead of replacing clinicians
• Reports ~60% admin-task reduction and ~6x faster enrollment (vendor-stated)

Ideal Use Case

A Medicaid or Medicare Advantage plan uses Sage to call hard-to-reach members for enrollment, check-ins, and disease-management follow-up, freeing human care managers to focus on the highest-acuity cases.

How Ellipsis Health differentiates

Unlike ambient clinical-documentation scribes such as Nabla, Suki, or Abridge, Ellipsis Health is not a note-taker for the exam room; it runs the patient phone call itself as a care-management agent. Its differentiator is the vocal-biomarker layer, which reads emotion and mental-health cues from voice rather than only transcribing words. Compared with generic voice-bot platforms, the model is tuned on clinical calls and aimed at behavioral health, where rapport drives engagement. The trade-off is scope: it concentrates on care-management outreach for payers and at-risk providers, so organizations wanting a broad documentation or general contact-center tool will still need separate systems. Outcome figures are also company-reported and not yet independently published.
