Charta Health closed a $55 million Series B on November 10, led by Insight Partners. QuantumLight joined as a new backer while Madrona, Bain Capital Ventures and South Park Commons re-upped, taking funding since the 2023 founding to $85 million.
The San Francisco company sells autonomous AI chart review. Its engine ingests progress notes, operative reports, lab values and discharge summaries once a clinician closes an encounter, then adds codes the narrative documents and strips any that it cannot.
Coders who learned to code
Both founders, Justin Liu and Scott Morris, were engineering leads at Rockset, the real-time database firm OpenAI bought. Instead of dropping a general model into billing, they took a year to earn Certified Professional Coder credentials and audited the workflow with more than 100 health system and payer executives.
That discipline now shapes hiring, with formal medical coding certification mandatory for every engineer and go-to-market employee.
Two products, one engine
The financing launches two units on one shared model. Charta for Providers scrubs charts before the bill drops, inside the EHR, and runs at American Family Care, Grow Therapy and the Pediatric Associates Family of Companies.
Charta for Payers, built with one of the country’s largest health plans, covers Hierarchical Condition Category coding, second-pass claim review and HEDIS care gap detection for Medicare Advantage and ACA marketplace books.
Fixing the argument, not the paperwork
Denials and appeals are a slow tax on the system. Liu argues a chart should be settled before the claim goes out, not contested months later.
“When every chart gets reviewed, accuracy stops being a guess,” Liu said. Health plans and provider groups will test that promise against their own post-payment audits.
