Phylagen is a San Francisco-based biotechnology company focused on decoding the indoor microbiome—the complex community of viruses, bacteria, and fungi that populate interior spaces. Guided by Dr. Jessica Green, the team merges microbial genomics with data analytics to derive actionable insights for indoor health and safety, including pandemic response and methods to verify supply chains. The company and its work have drawn attention from major outlets and have earned recognition from the World Economic Forum as a Technology Pioneer. In October 2021, Phylagen introduced a consumer-facing test designed to evaluate cleaning effectiveness in homes, marking a move into practical, at-home applications. The firm has pursued collaborations to apply its science in real-world environments, including a joint development agreement with Johnson Controls and a partnership with AOAC International to validate its COVID-19 indoor test.
