The healthcare ecosystem, fully mapped
The Definitive ID offers a simple way to uniquely identify individuals and organizations in the healthcare market. We assign a proprietary identifier to every player in the healthcare ecosystem, from hospitals and physicians to payors and GPOs, to map out industry relationships and inform growth strategies.
Bringing everything together
Our approach provides a comprehensive, detailed view into the affiliations that make up larger networks and systems and shows how individual entities are connected and interact. Our team assimilates, normalizes and categorizes large amounts of unstructured data to make sure all entities are represented and connected.

Seeing the whole market
The Definitive ID powers the Atlas Dataset for a comprehensive view of the fragmented healthcare ecosystem, helping businesses navigate the market and make smarter decisions.

Pushing what's possible
Our proprietary technology blends manual research with data science and advanced tools to deliver reliable, high-quality intelligence. We use NLP to extract and normalize data from multiple sources, then apply methods like geolocation to link identifiers across datasets—powering the Definitive ID. This reveals insights that manual research alone couldn't uncover, such as connections between people and organizations.
