Arrow is a New York-based healthcare technology company building an AI-powered operating system for revenue cycle management (RCM). Formerly known as Walnut and often described as 'Stripe for healthcare,' Arrow helps healthcare organizations reduce claim denials, accelerate collections, and run billing, claims, and payer communications from a single platform. Founded in 2020 by Roshan Patel and Yash Joshi, the company emerged from stealth in 2024 with $110M in Series A financing led by Gradient Ventures.

Roshan Patel is the co-founder and CEO of Arrow, a New York-based healthcare payments company (formerly Walnut) that uses AI to detect claim errors, accelerate reimbursement, and give revenue cycle teams real-time visibility into what payers are doing. He built the original company as a buy-now-pay-later product for medical bills after watching a family member's bills pile up, raised a $110 million Series A led by Gradient Ventures in 2022, then pivoted the business toward provider-side claims infrastructure and rebranded to Arrow in 2024.
