Business Model
What each company does and how it makes money
Adaptive Biotechnologies is a biotechnology company that develops immune medicine platforms for diagnosing and treating diseases like cancer, autoimmune disorders, and infectious diseases. It generates revenue primarily through its clinical diagnostics segment — including its clonoSEQ test for minimal residual disease monitoring — and its translational and clinical genomics research services, with diagnostics contributing roughly 60% of revenue. The company's key advantage lies in its proprietary immune medicine platform that maps and translates the genetics of the adaptive immune system into clinical diagnostics and therapies.
Vertex Pharmaceuticals is a biotechnology company focused on developing and commercializing transformative medicines for serious diseases, with its flagship franchise targeting cystic fibrosis. It generates nearly all its revenue from CF therapies — primarily Trikafta/Kaftrio — while building a pipeline in pain, kidney disease, and type 1 diabetes. Its moat stems from deep scientific expertise in CFTR biology and a dominant, near-monopoly position in the CF treatment market.
