Full time

Company Summary:

Founded in 2017 within Flagship Labs, Cellarity’s new approach to drug discovery is based on the computational modeling of cell behavior, leading to a more complete understanding of system and network biology to uncover cell-behavior-targeted medicines for a wide variety of diseases. Cellarity recently raised $123 million in Series B financing. The round included contributions from funds and accounts managed by BlackRock, The Baupost Group, Banque Pictet on behalf of their clients and eight other investors alongside Flagship Pioneering.

Cellarity is generating unprecedented biological insights by combining its unique expertise in network biology, high-resolution data, and machine learning. The result is a new understanding of the cell’s trajectory from health to disease, and how cells relate to one another in tissues. Because the cell and its network of transcripts and proteins offer a more complete view of the complexity of human biology than any individual molecular target, Cellarity’s approach allows for more efficient drug discovery and is designed to drive higher rates of clinical success. Already, the company has seven drug discovery programs underway in diverse therapeutic areas that range from metabolic disease to immuno-oncology.

The successful Series B financing round validates the strength of Cellarity’s science and its potential to redefine drug discovery through its cell-centric approach.
