resbiotic
resbiotic is a physician-founded microbiome health company building clinically tested probiotics, prebiotics, postbiotics, and bioactive botanicals around its Gut-X Axis platform - the idea that the gut talks to the rest of the body. Its flagship resB Lung Support is positioned as the first clinically tested probiotic targeting the gut-lung axis for respiratory health. Founded in 2020 by physician-scientist Dr. C. Vivek Lal out of microbiome research at the University of Alabama at Birmingham, the company sells direct-to-consumer and through retail including Walmart and GNC, and has raised roughly $20.6M to date.
Biohm Technologies
Biohm Technologies is a Cleveland-based microbiome innovation company that studies the gut as a whole - bacteria and fungi together - rather than bacteria alone. Built on 40+ years of fungal research by Dr. Mahmoud Ghannoum, the scientist who named the mycobiome, Biohm develops data-driven biotic ingredients and gut-health testing solutions. Its flagship ingredient Mycohsa is the first probiotic blend clinically shown to break down digestive biofilms, and its Symbiont discovery platform mines a large bacterial-fungal dataset to design targeted microbiome products. After a B2B pivot in 2024, the company now sells ingredients and microbiome science to nutraceutical and food brands.
