Company Overview
About H1
H1 is a healthcare data technology company building the industry's most comprehensive provider data platform, serving life sciences companies, health plans, hospitals, and digital health organizations. Founded in 2017 and headquartered in New York, H1 aggregates data on millions of healthcare professionals worldwide — including clinical expertise, publication records, trial participation, prescribing patterns, and network affiliations — and makes this data accessible through a unified platform and API layer. Life sciences customers use H1 to identify key opinion leaders, optimize clinical trial site selection, and target medical outreach with precision; health systems and payers use it for directory management, credentialing, and network adequacy analysis.
Business Model & Competitive Advantage
H1 has raised over $305M in total funding, including a $100M Series C led by Altimeter Capital with participation from Goldman Sachs Asset Management and Flex Capital. In 2025, the company executed two significant acquisitions: Ribbon Health (January 2025), a provider data management platform used by health plans and digital health companies for directory accuracy and network management; and Veda Data Solutions (June 2025), a specialist in healthcare provider data normalization and automation. These acquisitions position H1 as the first end-to-end provider data platform spanning directories, networks, rosters, credentialing, and provider data management — a vertically integrated stack across both the life sciences and payer/provider markets.
Competitive Landscape 2025–2026
H1's network effect strengthens with each new data source and customer: as more organizations contribute and validate provider data, the platform becomes the authoritative source of truth for healthcare professional information. The company competes with specialized point solutions including Veeva's KOL data products, Definitive Healthcare, and legacy credentialing systems, but differentiates through breadth of provider coverage, AI-driven data quality, and its expanding two-sided market connecting life sciences with the provider ecosystem.
