Arintra raises $21M to revolutionize AI medical coding

108

Arintra, a GenAI-native autonomous medical coding platform, has just pulled in $21 million in Series A funding—a clear signal that investors are betting heavily on the potential of AI to shake up healthcare. The round, led by Peak XV Partners, also drew support from Endeavor Health Ventures, Y Combinator, Counterpart Ventures, Spider Capital, Ten13, and several other strategic players. But this isn’t merely a financial headline. For Arintra, it’s permission to dream bigger: ramp up adoption across U.S. health systems, push product innovation, grow its team, and set up a Bay Area headquarters that can serve as a launchpad for its ambitions.

Since its founding in 2020 by Nitesh Shroff and Preeti Bhargava, Arintra has charted an unusual path. It’s not just another startup chasing venture capital. The platform, powered by GenAI, autonomously converts clinical documentation into accurate insurance codes—cutting through the messy, error-prone tangle of traditional medical billing. And it doesn’t stop there. Unlike conventional bolt-on solutions, Arintra weaves directly into EHR systems like Epic and Athena, combining automated coding with clinical documentation improvement (CDI) and denial prevention. The result? Healthcare providers not only safeguard their revenue but also reduce costs, speed up cash flow, and maintain rigorous compliance. It’s efficiency without compromise, and it’s the kind of solution the industry has been quietly begging for.

The timing couldn’t be more critical. Hospitals and physician groups are wrestling with tight budgets, coder shortages, and complex payer requirements. With over $1 billion in processed healthcare charges and proven ROI for clients such as Mercyhealth and Reid Health, Arintra is steadily carving out a leadership position in the $150 billion U.S. healthcare reimbursement sector.

1. Introduction to Arintra and Its Funding Milestone

1.1 Series A Funding Overview

Arintra’s $21 million Series A funding marks a pivotal moment in its growth story. Led by Peak XV Partners, the funding round attracted strategic backing from Endeavor Health Ventures, Y Combinator, Counterpart Ventures, Spider Capital, Ten13, and several other influential investors. The capital infusion is set to supercharge Arintra’s nationwide adoption, fuel cutting-edge product innovation, expand its talented team, and establish a Bay Area headquarters, all aimed at meeting surging demand from healthcare providers eager for AI-driven revenue assurance solutions.1.2 Importance for Healthcare AI

This funding isn’t just a financial milestone—it’s a statement. Arintra’s ability to automate complex coding workflows places it at the forefront of healthcare AI, tackling pressing revenue cycle challenges while boosting operational efficiency and patient outcomes. Investors clearly see tangible market potential in AI-driven revenue assurance solutions.

2. Startup Background and Founders

2.1 Founding Story

The story starts with an irritating, all-too-common real-world problem. Back in 2020, Nitesh Shroff (CEO) and Preeti Bhargava (CTO) found themselves knee-deep in the chaos of traditional medical billing—a world riddled with delays, errors, and endless paperwork. Most people would have shrugged and accepted it as “just how it works.” But they didn’t. They saw the frustration, the missed revenues, the coder shortages, and thought: we can fix this. They merged deep technical expertise with an intimate understanding of healthcare pain points to create a GenAI-native platform that doesn’t just automate coding—it challenges the very assumptions of the system. Their aim was bold: empower providers to reclaim financial control while tackling inefficiencies that had long crippled healthcare operations.

2.2 Leadership Profiles

Nitesh Shroff, Co-founder & CEO: Shroff is not your typical startup CEO. He steers Arintra with a mix of audacity and purpose, shaping enterprise adoption, scaling strategy, and investor confidence. His approach is intensely mission-driven—he’s obsessed with overhauling healthcare revenue cycles, viewing AI not merely as a tool, but as a transformative force. Every decision reflects a careful blend of bold vision and grounded pragmatism, ensuring growth is rapid but sustainable. Shroff’s leadership embodies both foresight and relentless execution.

Preeti Bhargava, Co-founder & CTO: Bhargava brings a rare combination of clinical insight and technical mastery. She drives product development with a hands-on, meticulous approach, making sure the platform integrates seamlessly into clinicians’ daily workflows. By fusing cutting-edge AI with real-world clinical experience, she turns what could have been a cold, technical system into something intuitive, powerful, and genuinely empowering. With her direction, autonomous medical coding becomes more than a concept—it becomes a tangible solution that dramatically enhances revenue assurance for providers while simplifying their day-to-day operations.

3. Arintra’s Working Model

3.1 GenAI-Native Autonomous Coding

Arintra harnesses the raw potential of large language models (LLMs) and clinical knowledge graphs to turn medical coding on its head. What used to be a dull, painstaking, and error-laden chore now happens with precision and speed. And this isn’t just about ticking boxes—every code the system produces can be audited, fully explained, and confidently trusted to meet the toughest compliance standards. The payoff? Hospitals not only cut down on costly mistakes but also reclaim lost revenue and sidestep the bureaucratic gridlocks that have long throttled their financial flow.

3.2 Seamless EHR Integration

This isn’t some add-on gimmick. Arintra dives deep into EHR systems like Epic and Athena, embedding itself into the workflow rather than sitting on the surface. Hospitals don’t have to overhaul their processes. Instead, they gain automation, clinical documentation improvement (CDI), and denial prevention all in one platform—a combination that’s rare in today’s medical software landscape.

3.3 Revenue Assurance Approach

Arintra’s approach to revenue assurance is refreshingly pragmatic. It doesn’t just claim to work—it proves it in action. By fusing automated coding with hands-on denial prevention, the platform actually speeds up payments, cuts down on repeated claim denials, and keeps cash moving where it belongs. But this isn’t merely about being faster or slicker. It’s about giving healthcare organizations a real chance at financial resilience in a reimbursement landscape that’s constantly shifting and relentlessly complicated.

4. Revenue Model and Business Strategy

4.1 Enterprise SaaS Model

Arintra operates on a subscription-based SaaS model, catering to hospitals, physician groups, and sprawling health systems. But this isn’t merely about scalability—it’s a calculated, strategic play. By weaving itself seamlessly into clinicians’ daily workflows, Arintra delivers results that don’t just feel automated; they feel like an experienced teammate quietly taking the strain off staff. Billing gets tighter, accounts receivable moves faster, and ROI isn’t promised—it’s demonstrably realized.

4.2 Client Impact and ROI

• Mercyhealth: Experienced a concrete 5.1% revenue boost, a jaw-dropping 43% reduction in claim denials, and a 32% shrinkage in coding costs. These figures aren’t sterile statistics—they represent smoother operations, reclaimed staff hours, and breathing room in a notoriously tense billing environment.
• Reid Health: Revamped accounts receivable speed and dramatically sharpened coding accuracy. The ROI arrived swiftly and tangibly, without forcing teams to rearrange their workflows or endure disruption.

5. Challenges Solved by Arintra

5.1 Healthcare Reimbursement Inefficiencies

Providers navigate a daily minefield of wafer-thin margins, chronic staff shortages, and bewilderingly intricate payer regulations. Manual coding? It’s slow, fragile, and inevitably riddled with errors. Every missed or misapplied code isn’t just a line item—it’s money lost, frustration mounted, and a gnawing sense that the system is stacked against efficiency. Arintra doesn’t just plug the holes; it reshapes the process to make revenue capture almost effortless, lifting burdens that have long weighed on billing teams.

5.2 Automation and Compliance

Arintra tackles this head-on. Its AI-driven coding doesn’t just automate—it enforces compliance, integrates denial prevention, and cuts down the endless back-and-forth of manual corrections. Providers experience fewer interruptions, more accurate billing, and a steadier, more predictable cash flow. It’s not a gimmick; it’s a system designed to work the way real hospitals operate.
