CertifyOS and Candor Health Partnership Announced

CertifyOS and Candor Health partnership announced. Its strategic partnership streamlines provider data accuracy with integrated change management and credentialing support. CertifyOS has announced a strategic partnership to create the most accurate, intelligent, and scalable Provider Data Management (PDM) solution in the healthcare industry. This collaboration brings together CertifyOS's next-generation Master Data Management (MDM) and provider data infrastructure with Candor Health's unmatched data accuracy engine to transform how health plans manage, verify, and operationalize up-to-date provider data. By combining CertifyOS's scalable and modernized PDM platform with Candor Health's deep expertise in provider data accuracy, the two companies are addressing the fragmentation that has burdened health plans for decades. Together, they unlock the operational efficiency, compliance readiness, and real-time provider intelligence that health plans need to meet evolving regulatory requirements and improve the member experience - all in service of better healthcare outcomes. "Candor leverages AI and machine learning to deliver accurate, near real-time provider data that enhances health plans' operational efficiency, compliance, and member experience," said Sury Agarwal, CEO of Candor Health. "Integrating our up-to-date provider data with CertifyOS's MDM infrastructure creates a unified solution that not only validates and manages provider information but also enables instant actions across a provider network. This collaboration addresses critical gaps in provider data management, offering a scalable and compliant infrastructure that empowers health plans to optimize network operations and deliver seamless care experiences." Trusted by dozens of health plans and digital health organizations, CertifyOS is the leading provider data intelligence company unifying workflows across intake, credentialing, monitoring, provider data management, and roster management. Its end-to-end provider data infrastructure platform ingests provider information from multiple sources, applies AI-driven entity resolution and survivorship rules to reconcile conflicting inputs, and normalizes everything into a single source of truth. By storing data at the atomic level, CertifyOS enables flexible configuration of business rules, seamless integration with downstream systems, and a 360-degree view of each provider. Candor Health further strengthens CertifyOS's platform by using AI to continuously cross-check tens of thousands of sources to confirm critical details - from practice locations and affiliations to specialties, licensure, and availability - and refreshes them on a near real-time basis. By integrating Candor Health's high-fidelity data onto CertifyOS's intelligent infrastructure, health plans can be even more confident that they are working with the most complete and current view of their networks. CertifyOS's platform scales with provider networks and can integrate directly into downstream workflows, such as claims, contracting, and directories. "Accuracy without lasting survivorship and action is meaningless," said Anshul Rathi, CEO of CertifyOS. "Candor is the best in the world at producing precise, up-to-date provider data using AI. CertifyOS is the only platform built to maintain and operationalize it. Together, we're not just offering a better PDM system; we're delivering the accurate infrastructure healthcare has been waiting for." This partnership also accelerates both companies' shared vision of helping health plans move from reactive compliance to proactive provider intelligence. With the combined solution, payers can now streamline provider onboarding, avoid claim denials, prevent fraud, and deliver a better provider and member experience - all while reducing administrative burden. Health plans interested in learning more can contact either organization directly to schedule a tailored demo. About Candor Health Candor Health is an AI-native provider data accuracy platform built to solve one of healthcare's most persistent challenges: unreliable provider information. Powered by a continuously verified, near-real-time national directory, Candor transforms fragmented records into trusted intelligence that flows seamlessly across the healthcare ecosystem.
