How it happened
Definitive Healthcare sells a 'healthcare commercial intelligence' SaaS platform — data and analytics on hospitals, physicians and the health-care market used by life-sciences and medtech sales teams. It went public in September 2021 at roughly a $3.9B valuation amid the health-data boom. Growth decelerated sharply as customers cut software spending, and the stock fell about 96%, leaving the company worth around $150M.
