Business Model
What each company does and how it makes money
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.
Cogent Biosciences is a biotechnology company developing precision therapies for genetically defined diseases, particularly focusing on cancers driven by specific mutations. The company generates revenue primarily through research collaborations and licensing agreements — it currently has no commercial products and relies on funding from partnerships and equity offerings to advance its clinical pipeline. Its key competitive advantage lies in its targeted approach to inhibiting specific oncogenic mutations like KIT D816V, which could offer differentiated efficacy and safety profiles compared to broader kinase inhibitors.
