Business Model
What each company does and how it makes money
RAPT Therapeutics is a clinical-stage biopharmaceutical company developing oral small molecule therapies for cancer and inflammatory diseases. It generates no revenue yet as it's in clinical trials, with future income dependent on potential drug approvals and commercialization. The company's competitive advantage lies in its targeted CCR4 antagonist platform that selectively inhibits immune cell migration to diseased tissues.
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.
