Switch Therapeutics is a South San Francisco preclinical biotech building conditionally activated siRNA (CASi) therapies that only switch on inside the cell types where they're needed. The platform - born from research at Caltech, Harvard and City of Hope - aims to make RNA interference safe enough for the brain, with a lead program targeting APOE for Alzheimer's disease.
Atomic AI is a South San Francisco biotechnology company fusing machine learning with structural biology to unlock RNA drug discovery. Its platform pairs in-house wet-lab chemical-mapping data with deep learning models - including ATOM-1, a foundation model for RNA structure, and PARSE, its RNA structure exploration platform - to find structured, ligandable RNA motifs and design selective small molecules and RNA-based medicines for targets long considered undruggable.
Strand Therapeutics is a clinical-stage biotech building 'programmable' mRNA medicines - drugs engineered with logic circuits so they switch on the right protein, in the right cell, at the right time. Spun out of MIT in 2017 by synthetic biologists who wrote the first programming language for mRNA, Strand's lead candidate STX-001 is a self-replicating mRNA that makes tumors manufacture their own IL-12, turning cold cancers hot from the inside. Backed by Kinnevik, Regeneron, Amgen and Eli Lilly with over $250M raised.
