About

Our founder Noah, an experienced tech entrepreneur, was directly impacted by a severe genetic disease when his daughter was diagnosed with Rett Syndrome, a disease that afflicts 1 in 10,000 girls. Using an innovative polytherapy strategy, we’ve successfully improved her quality of life, and have designed new therapeutics that each could be worth billions and together could deliver a cure.
