AI clinical compliance that audits charts before billing
Brellium is a New York City AI-powered clinical compliance and revenue integrity company. Its platform audits clinical documentation and coding before claims go out, catching compliance risk ahead of clawbacks and surfacing under-billed revenue. The company says it covers all 50 U.S. states and 100+ payors, and is trusted by hundreds of thousands of providers. On 13 October 2026 it announced $23 million in venture funding led by Left Lane Capital and First Round Capital, with participation from Digital Health Venture Partners, following a prior Series A. CEO Zach Rosen leads the company, which was founded in 2021.
