About
Anto Biosciences is building a foundation model for microbial communities, making the gut microbiome computable for the first time. We predict drug toxicity and efficacy across diverse populations and fix drugs so they work for everyone — solving the hidden root cause of most drug failures.
Founded by Arvid (Broad Institute of MIT and Harvard; Nature-published researcher who pioneered quality-aware, goal-directed sparsification) and David (Harvard Medical School Gastroenterology, J&J), second-time founders who published the breakthrough at leading machine learning AI conferences and Nature.
We've caught a $1B cancer drug that worked in China but failed clinical trials in the U.S. With the help of our model, we are the first ones to know exactly why.
Anto is backed by Y Combinator (F25). https://www.anto.bio/
