Our mission is to simplify healthcare payments through our modern cloud-based software, enabling our healthcare clients to prioritize patient care and optimize their financial performance. Waystar provides healthcare organizations with mission-critical cloud software that simplifies healthcare payments. Our enterprise-grade platform streamlines the complex and disparate processes our healthcare provider clients must manage to be reimbursed correctly, while improving the payments experience for providers, patients, and payers. We leverage internally developed artificial intelligence (“AI”) as well as proprietary, advanced algorithms to automate payment-related workflow tasks and drive continuous improvement, which enhances claim and billing accuracy, enriches data integrity, and reduces labor costs for providers. Put simply, our software helps providers get paid faster, accurately, and more efficiently, while ensuring patients receive a modern, transparent, and consumer-friendly financial experience. The healthcare payment ecosystem is highly complex, beginning with pre-service patient onboarding and extending through post-service revenue collection, with dozens of interdependent steps in between. Within this multi-step workflow, the process for determining how much a provider should be reimbursed involves millions of permutations of variables, such as over 10,000 diagnosis codes that are constantly changing and unique payer contracts, each with individual rules, processes, and reimbursement requirements. The burden borne by providers of tracking and managing all of these variables, coupled with a constantly evolving regulatory framework, often results in incorrect payments or denials that require time-consuming appeals procedures to resolve. Historically, healthcare providers have relied upon a patchwork of manual processes and systems to navigate these complexities and support their payment functions. However, this legacy approach has resulted in workflow delays, lost revenue, and slower time to payment. Our purpose-built software platform addresses these challenges and optimizes healthcare payments across all stages of the patient journey. Our clients utilize our software to manage pre-encounter workflows such as eligibility checks and prior authorization approvals, as well as mid- and post-encounter workflows such as co-pay collection, claims submission and monitoring, and payer remittances. Our software is used daily by providers of all types and sizes across the continuum of care, including physician practices, clinics, surgical centers, and laboratories, as well as large hospitals and health systems. We currently serve approximately 30,000 clients of various sizes, representing approximately one million distinct providers practicing across a variety of care sites, including 18 of the top 22 U.S. News Best Hospitals. Our client base is highly diversified, and for the year ended December 31, 2023, our top 10 clients accounted for only 11.3% of our total revenue. Our business model is designed such that as our clients grow to serve more patients, their claims and transactional volumes increase, resulting in corresponding growth in our business. In addition, our clients frequently adopt a greater number of our solutions over time and introduce our solutions across new sites of care. The number of clients from whom we generate over $100,000 of revenue has grown from 920 in the twelve months ended March 31, 2022 to 1,007 in the twelve months ended March 31, 2023 to 1,080 in the twelve months ended March 31, 2024, driven by large, new client wins and successful cross-selling and up-selling efforts. In 2023, we facilitated over five billion healthcare payments transactions, including over $1.2 trillion in gross claims volume, spanning approximately 50% of patients in the United States. Our platform benefits from powerful network effects. Our cloud-based software is driven by a sophisticated, automated, and curated rules engine, employing AI to generate and incorporate real-time feedback from millions of network transactions processed through our platform each day. Every transaction we process provides additional data insights across providers, patients, and payers, which are embedded in updates that are deployed efficiently across our client base. This results in cumulative benefits to us over time — as we capture more data from each transaction we process, we leverage that data to continue to improve the Waystar platform through embedded machine learning, advanced algorithms, and other in-house AI technologies to deliver added value to our clients. In turn, the more value we create for our clients, the more likely it is that they will continue to use our products, allowing us to continue to capture more data that results in tangible improvements to our platform. As a result, our clients benefit from faster and more efficient performance from software that is evolving to meet ever-changing regulatory and payer requirements, enabling accurate and timely reimbursement. We have demonstrated an ability to drive recurring, predictable, and profitable growth. Over 99% of our revenue is either recurring subscription or based on highly predictable volumes. For the twelve months ended March 31, 2024, our Net Revenue Retention Rate was 108.8%, and for the year ended December 31, 2023, our Net Revenue Retention Rate was 108.6%. We were originally incorporated in Delaware on August 13, 2019 and subsequently changed our name to Waystar Holding Corp. on August 11, 2023. Our principal offices are located at 1550 Digital Drive, #300, Lehi, Utah 84043 and 888 W. Market Street, Louisville, Kentucky.
