Anto Biosciences is a biotechnology company specializing in developing a multimodal AI foundation model to make the gut microbiome computable for drug development. Founded in 2025 by Arvid E. Gollwitzer and David de Gruijl in the San Francisco Bay Area, the company aims to predict drug toxicity and efficacy across diverse populations by integrating multimodal microbial data with quality-aware sparsification techniques. This approach identifies microbiome-mediated mechanisms of drug response, informing molecule optimization to enhance therapeutic effectiveness.
