Lumen Health
AI triage for primary care clinics
Seed Round · $2.5M
May 2026 · Confidential
Investor One-Pager
Cutting primary care wait times by 73% with AI triage that doctors actually trust.
Lumen embeds in the EHR, auto-prioritizes patient messages, and frees up 9 hours of clinician time per week — saving the average clinic $87k/yr in burnout-driven turnover.
⚠ The Problem
Clinic inboxes are drowning.
A solo PCP gets 60–120 patient messages a day. Triaging them eats 2.5 hours of clinical time per provider, drives 78% of burnout-related quits, and pushes urgent cases behind requests for refills.
✓ Our Solution
An AI triage layer that fits in 15 minutes.
Lumen reads inbound patient messages, classifies urgency, drafts a clinician response, and surfaces only the messages that need a human. Sits inside Epic, Athena, eClinicalWorks — no new login, no workflow change.
