Business Model
What each company does and how it makes money
PureTech Health is a clinical-stage biotherapeutics company that discovers and develops novel medicines for inflammatory, fibrotic, immunological, neurological, and other challenging diseases. It generates revenue primarily through strategic partnerships, licensing agreements, and milestone payments from pharmaceutical collaborators — with its pipeline including KarXT for schizophrenia and psychosis in Alzheimer's disease, regenerative biology platforms, and immunomodulation therapies. The company's key advantage lies in its innovative platform technologies — including its lymphatic targeting, oral biologic delivery, and microbiome-based approaches — which enable novel treatment mechanisms for difficult-to-treat conditions.
Centessa Pharmaceuticals is a clinical-stage biopharmaceutical company developing novel medicines for serious diseases. It generates revenue primarily through research collaborations and licensing agreements — though as a pre-commercial company, it currently relies on equity financing and partnerships to fund development. The company's competitive advantage lies in its asset-centric model — each program operates as an independent "company" with dedicated resources and accountability — and its LockBody platform technology designed to create targeted cancer therapies with reduced systemic toxicity.
