Cellares

Biotech & Life Sciences · South San Francisco, United States · Founded 2019 Unicorn

Cellares is a pioneering startup operating in the biotechnology sector, specifically in the development and manufacturing of cell therapies. Based in South San Francisco, California, with additional operations in Europe and Asia, the company has established itself as the first Integrated Development and Manufacturing Organization (IDMO). This means it combines the processes of developing and manufacturing cell therapies under one roof, which is a significant innovation compared to conventional Contract Development and Manufacturing Organizations (CDMOs) that separate these processes. Cellares' business model is centered around its proprietary "Smart Factory" technology. These factories are equipped with advanced cell therapy manufacturing technologies, including an automated single-use cartridge system. This technology allows for a 10x increase in productivity, a 50% reduction in cost per batch, and a 75% reduction in process failure rates compared to conventional CDMOs. The company serves a wide range of clients, including preclinical, clinical, and commercial entities. It has also formed strategic partnerships with major pharmaceutical companies like Bristol Myers Squibb and Lyell, to evaluate automated manufacturing of their CAR-T cell therapies on Cellares' Cell Shuttle Platform. Cellares makes money by offering its advanced manufacturing services to these clients. The company's competitive pricing and increased productivity make it an attractive option for businesses looking to develop and manufacture cell therapies more efficiently and at a lower cost.
