Concerto Biosciences rebuilds microbial communities in, on, and around us to heal our bodies and our planet. Products that rebuild microbial communities do not yet exist because no one can map the vast inter-species interaction networks responsible for community behavior. Concerto’s cofounders therefore invented the first-ever ultra-high-throughputplatform to experimentally measure millions of microbial interactions. Concerto maps interaction networks that reveal a new class of products called “ensembles”—combinations of microbes that work in concert to shepherd damaged microbial communities to health. The opportunities are enormous: Concerto will become the premier inventor of ensembles across medicine and agriculture, reinventing humanity’s relationship with microbes. ListsSomething looks off?
