Nitra Raises $187M as AI-Native Operating System for Healthcare Practices Tops $1B in Processing Volume
Nitra secured $187 million across its Series A and B, venture debt, and an expanded warehouse facility, bringing total capital raised to $205 million and total equity to $90 million. The raise follows a year of 740%+ revenue growth in 2025 and more than $1 billion in annualized processing volume across thousands of physicians and 700+ clinics.
The company projects crossing 3,000 clinics, more than $150 million in annualized revenues, and over $4 billion in annualized processing volume in 2026. Headcount is expected to scale from 50 last year to 200+ by year-end as the team builds out new modules in revenue cycle management, patient marketing, and payroll/staffing.
Why this matters for healthcare operators
Administrative drag is eating margins and clinician time. Practices juggle disconnected tools for payments, procurement, inventory, scheduling, and insurance verification-systems that were never built to talk to each other.
Nitra's approach is straightforward: embed AI agents into the operational backbone so front desk, billing, procurement, and finance tie together. Less swivel-chair work. Clearer visibility. Faster cash flow.
What Nitra offers today
- Financial Automation: Visa-powered expense card, expense management, bill pay, patient payment processing, and AI agents for healthcare accounting automation.
- Commerce & Inventory: Direct access to tens of thousands of biopharma and medical equipment products via partners like McKesson and Medline. AI procurement agents negotiate pricing, onboard vendors, execute purchases, and monitor inventory end-to-end.
- Patient Management (new): Voice AI agents for scheduling and insurance eligibility checks. Scheduling, benefits verification, and patient communication integrated into the same operational stack.
Traction and outlook
In 2025, Nitra grew from $4 million to $33+ million in annualized revenue and processed over $1 billion in annualized volume across its platform. In one day last December, physicians used the system to complete roughly $9 million in critical biopharma and medical purchases.
Customers include Bay Area Retina Associates, Southern Vitreoretinal Associates (SVA), Elase Medspa, PhyNet Dermatology, Brandywine Urology, and Empower Aesthetics. The company plans to accelerate AI development and expand engineering capacity to meet demand across specialty and multi-site groups.
Leadership and governance updates
Dr. Richard Park, founder and former CEO of CityMD (later combined with Summit Health and acquired by VillageMD for $8.9B in 2023), has joined Nitra's Board of Directors. He brings deep operational experience scaling urgent care and physician services at national levels.
"We're on a mission to serve the people that serve our communities and help doctors save time and money," said CEO Tim Hwang. "Practices are running critical workflows across disconnected systems that were never designed to work together. Nitra brings those layers together into a single AI-native operating system that helps healthcare practices run their operations more efficiently."

What to watch if you lead a practice or MSO
- Consolidate workflows: Map your current stack (payments, AP, inventory, scheduling, verification). Quantify tools, logins, and handoffs. Prioritize 2-3 handoffs to eliminate first.
- Cash flow impact: Track DSO, credit terms, and SKU-level purchasing costs before/after any rollout. Tie AI automations to real savings in time and spend.
- Procurement guardrails: Require AI-driven purchasing to follow formulary rules, supplier lists, and approval thresholds. Measure avoided stockouts and price improvements.
- Front desk load: For voice scheduling and eligibility, baseline call volume, average handle time, and abandonment rate. Aim for fewer manual verifications and cleaner eligibility upfront.
- Data integrity: Confirm audit trails for every action taken by an AI agent. Demand reconciliation across EHR, accounting, and inventory systems.
- Pilot smart: Start with one specialty, 2-3 locations, and a 60-90 day pilot. Set weekly metrics reviews and a go/no-go gate tied to measurable ROI.
Fast facts
- $187M in new financing; $205M total capital; $90M total equity
- 740%+ revenue growth in 2025; $4M to $33M+ annualized revenue
- 1B+ in annualized processing volume; $9M in purchases processed in a single day
- On track for 3,000+ clinics, $150M+ annualized revenue, and $4B+ processing volume in 2026
- Team growth: 50 to 200+ by end of 2026
Bottom line
Administrative overhead is fixable. Nitra's bet is that AI agents embedded across finance, procurement, and patient operations can return time to clinicians and clarity to managers-without adding yet another disconnected tool.
If you're evaluating platforms in this space, start with a tight pilot, lock metrics upfront, and hold the vendor to the ROI. Simpler stack, faster cash, fewer manual loops-that's the win.
