Business Model
What each company does and how it makes money
Kymera Therapeutics is a biopharmaceutical company developing targeted protein degraders — small molecules that harness the body's natural protein degradation system to eliminate disease-causing proteins. It generates revenue primarily through strategic partnerships and milestone payments from pharmaceutical collaborators — with potential future revenue from drug sales if clinical candidates succeed. The company's key advantage is its proprietary Pegasus platform for discovering novel protein degraders, which targets previously "undruggable" proteins and creates a pipeline of first-in-class therapies.
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.
