A Foundation Model for Microbial Communities.

What they do

Problem

Drug development and prescribing often fail because microbiome-driven differences cause unpredictable toxicity and efficacy across populations.

Solution

A foundation model that makes microbial communities (the gut microbiome) computable to predict drug toxicity/efficacy and guide fixes so drugs work across diverse populations.

Who it's for

Pharmaceutical and biotech companies developing and optimizing drugs, and potentially clinical researchers studying drug response.
