Flagship Labs 78 (FL78) is a well-funded, early-stage biotechnology company pioneering an innovative approach to therapeutic discovery and development. FL78 was founded through Flagship’s venture creation engine, where companies such as Moderna Therapeutics (MRNA), Rubius Therapeutics (RUBY), and Editas Medicines (EDIT) were conceived and created. Since Flagship’s founding in 2000, the firm has originated and fostered the development of nearly 100 scientific ventures resulting in $20+ billion in aggregate value, 500+ issued patents, and more than 50 clinical trials for novel therapeutic agents.
