Arintra Secures $25 Million to Automate Healthcare Revenue Cycles
San Francisco-based Arintra has closed a $25 million Series B funding round to scale its autonomous platform, which aims to resolve systemic billing inefficiencies across U.S. health systems. The company, which has now raised a total of $51 million, provides agentic AI tools designed to bridge the gap between clinical delivery and financial reimbursement.
The capital injection, led by Define Ventures with support from Peak XV Partners and Yale New Haven Health’s innovation arm, arrives as major health systems struggle with fragmented, manual processes. Arintra currently processes $5 billion in annual claim value for providers including UC Davis Health and Rochester Regional Health. By embedding directly into electronic health records, the platform automates coding across 23 specialties, reportedly increasing compliant revenue capture by 5.1% while slashing coding-related denials by 43%.
Unlike traditional point solutions, the platform provides an explainable audit trail that allows human coders to validate AI-generated recommendations rapidly. According to Tami McMasters Gomez of UC Davis Health, this hybrid approach has enabled teams to audit results 50% faster than previous manual methods. With the new funding, CEO Nitesh Shroff plans to expand the company’s enterprise footprint and deepen its specialty coverage, positioning the software as a foundational infrastructure requirement for hospitals facing mounting financial and labor pressures.
