Nitesh Shroff Is Teaching Hospital AI to Show Its Work
Before medical codes, Nitesh Shroff taught cameras and cars to interpret the world. At Arintra, he is applying the same discipline to a less visible problem: turning clinical documentation into an explainable, defensible claim.
Arintra
Arintra is an Austin-based healthcare AI company building a GenAI-native autonomous medical coding platform that turns clinical documentation into accurate billing codes directly inside hospital EHR systems. Founded in 2020 by machine-learning PhDs Nitesh Shroff and Preeti Bhargava, the company combines autonomous coding, clinical documentation improvement, and payer-aware denial prevention into a single revenue-assurance platform. Arintra has processed over a billion dollars in healthcare charges and, at customers like Mercyhealth, reports a 5.1% revenue increase and a 43% reduction in denials. It raised a $21M Series A led by Peak XV Partners in August 2025.
