Assured Health

Assured is the first AI-native provider network management platform built for healthcare organizations that cannot afford to wait months to get providers seeing patients and generating revenue. NCQA-certified as a Credentials Verification Organization (CVO) and backed by $6M in seed funding led by First Round Capital, Assured serves digital health companies, health systems, provider groups, and health plans nationwide. Organizations, including Houston Methodist, Tono Health, and Blossom Health, run their provider operations on Assured. Where traditional credentialing vendors depend on offshore teams, spreadsheets, and manual data entry, Assured deploys AI agents that verify credentials across 2,000+ primary sources in parallel, auto-generate and submit applications directly to payor portals and state licensing boards, and flag sanctions within 24 hours. The platform handles end-to-end credentialing, multi-state licensing across all 50 states, payor enrollment with automated roster management, and continuous compliance monitoring from a single system. Renewals initiate automatically 60 days before expiration. Integrations with CAQH, NPPES, PECOS, and plug-and-play APIs for your ATS, EMR, or Salesforce mean no rip-and-replace required. Credentialing delays cost healthcare organizations thousands in lost revenue per provider per month. Assured cuts that timeline from 60+ days to 48 hours. Payor enrollments close 30% faster with the highest first-pass approval rates in the industry. Sanctions get caught within 24 hours, not weeks. Teams go live in under 72 hours, see ROI within the first month, and reclaim 60+ hours per week previously buried in admin work. If your providers are sitting in a backlog, you are bleeding revenue. Assured stops the bleed.
