Charta Health has raised $55 million in a Series B round led by Insight Partners, the company announced on November 10, 2026. Madrona, Bain Capital Ventures, South Park Commons, and QuantumLight also participated. Charta did not disclose a valuation or its total funding to date; the three named investors besides Insight Partners previously backed the company's Series A.
What Charta Health builds
Charta sells an autonomous AI platform that reviews medical charts for coding accuracy, billing compliance, and documentation gaps. The software reads clinical notes the way a senior medical coder or compliance auditor would, flagging missing codes, checking that evaluation-and-management service levels match the documentation, and removing billed codes that lack sufficient support in the record.
The company has deployed its platform across urgent care, behavioral health, and pediatric provider networks, including American Family Care, Grow Therapy, and the Pediatric Associates Family of Companies. "We came to healthcare as engineers and saw a system where the most important data was locked in documents no one had time to read. Charta unlocks that data," said CEO and co-founder Justin Liu.
How the money will be used
Charta plans to use the Series B to accelerate research and development and to formally launch two business units built on a shared AI engine: Charta for Providers, aimed at helping clinics capture revenue they currently lose to under-coding, and Charta for Payers, aimed at helping insurers audit claims for compliance. Splitting the product this way lets Charta sell to both sides of the same billing dispute without maintaining two separate platforms.
Investors and prior rounds
Insight Partners led the new round as a first-time investor in Charta. Madrona, Bain Capital Ventures, and South Park Commons returned from the Series A, and QuantumLight joined as a new backer. Charta has not disclosed the size of its Series A or its cumulative funding since founding, and the company has stayed private about its current valuation.
Competitors and market context
Charta is entering a crowded field of AI companies attacking medical coding and revenue-cycle management, including Fathom, Nym Health, CodaMetrix, and Smarter Dx. What distinguishes Charta's pitch is its dual-sided approach: most rivals sell only to providers trying to capture more revenue or only to payers trying to catch overbilling, while Charta is building tools for both sides of the same dispute. The US medical coding and billing compliance market has drawn heavy venture interest over the past two years as hospitals and insurers look to cut the administrative overhead tied up in claims review, a cost that analysts have pegged in the tens of billions of dollars annually across the US health system.
What to watch next
The real test for Charta will be whether payers adopt a tool built by a company that also sells to the providers those payers audit — a potential conflict that competitors selling to only one side of the market do not face. How Charta for Payers performs with its first insurer customers, and whether Insight Partners' involvement opens doors to larger health plans, will shape the company's next round.
