About Us


Federation Bio was co-founded by Stanford and Venrock in 2019. Based on the work of two professors at Stanford – Dr. Michael Fischbach and Dr. Dylan Dodd – Federation Bio is pioneering powerful synthetic microbial cell therapies that have demonstrated potential to treat a wide range of diseases – from metabolic disorders to metastatic cancers. Unlike earlier approaches to microbial therapeutics, Federation Bio is generating potent, reproducible, and complete microbial consortia that stably engraft to provide predictable and durable responses.

Foundational to the company’s scientific approach is its first-in-class ACT™ (anaerobic co-culture technology) platform, which allows rapid and scalable manufacturing of rationally designed complex bacterial consortia.
