What H1.co does
H1 is a New York-based, privately-held healthcare data and AI company founded in 2017 by Ariel Katz and Ian Sax. It operates an AI-powered provider intelligence platform branded around its "Doctor Graph," which maps physician identities, affiliations, and clinical/prescribing activity across a proprietary global dataset of 12M+ HCP profiles, 14.6B claims (US, EU, Brazil, Japan), $73B in payments, 120M+ publications, 791K+ clinical trials, and 1K+ global congresses. The company reports serving 85% of top 20 pharmaceutical companies, 9 of top 10 health plans, and approximately 70% of digital health applications, with 200+ enterprise customers across six continents.
The product portfolio is organized into five suites — Clinical (Site Universe, Patient Universe, Site Performance Navigator, Clinical Intelligence Streams, Clinical MDM), Medical (HCP Universe, Medical Intelligence Streams, Medical MDM), Commercial (Prescriber Universe, Commercial Intelligence Streams, Commercial MDM), Health Plans (Directory Accuracy and Management, Roster Automation, Network Universe, Directory Stream), and Digital Health (Provider Foundation Data, Custom Networks, Patient Evidence Stream, H1 Foundation) — supplemented by enterprise APIs (Provider Search, Directory Validation, Network Adequacy, Claims Optimization) inherited from the Ribbon Health acquisition. AI capabilities are embedded throughout: the proprietary AI-powered Accuracy Scoring model trained on CMS-aligned validation, the Agent Protocol Reader for clinical trial feasibility, and generative AI features for medical affairs literature review. The platform also includes H1 Connect, a humanitarian program linking 8,000+ healthcare professionals with 120+ NGOs, and a research site profile offering at trials.h1.co.
H1 monetizes via enterprise SaaS subscriptions and data-as-a-service on multi-year contracts priced through a sales-led "Request a Demo" motion. The company has expanded through acquisitions of Carevoyance (2021), Faculty Opinions (2022, scientific discourse), Ribbon Health (2024, digital health APIs), and Veda Health (2025, health plan automation). H1 reports cash-flow and EBITDA profitability, forecasts 40%+ growth, and expects to operate above the Rule of 40 benchmark in 2026; its most recent capital event was a $40M strategic investment led by CVS Health Ventures in May 2026.
