Business Model
What each company does and how it makes money
Scinai Immunotherapeutics is a development-stage biopharmaceutical company focused on creating nanosized antibody therapies for infectious and autoimmune diseases. It generates revenue primarily through research collaborations and licensing agreements — notably with the Max Planck Society — while advancing its COVID-19 NanoAb and other pipeline candidates. The company's key advantage lies in its proprietary NanoAb platform technology, which aims to create smaller, potentially more effective antibody therapies compared to conventional antibodies.
Vaxcyte is a clinical-stage biotechnology company developing novel protein vaccines to prevent bacterial infectious diseases. It currently generates no revenue from product sales — relying on research funding and partnerships — but aims to commercialize its lead pneumococcal conjugate vaccine candidate, VAX-24, which is in Phase 1/2 clinical trials. The company's key advantage is its proprietary cell-free protein synthesis platform, which enables rapid design and production of complex vaccine candidates that are difficult to manufacture using traditional methods.
