Terrain Bio helps RNA therapeutics companies design and build better RNA, faster. Founded by innovators Omar Abudayyeh, Jonathan Gootenberg, and Patrick Hsu, along with Ex Nihilo, Terrain's mission is to enable better RNA therapeutics and vaccines. Leveraging the latest innovations in protein and RNA design and the deep expertise of its scientific cofounders, Terrain brings unparalleled speed and quality to RNA manufacturing. High-quality RNA enables the generation of experimental data that trains novel machine-learning models for RNA sequence design, creating a sandbox for scientists to design and build their own sequences. Through a catalog of commonly used sequences, custom RNA build, and AI-guided sequence design tools, drug developers gain access to a wealth of resources for every step of the journey to the clinic and beyond, with confidence that their sequences will be optimized for safety, efficacy, and manufacturability.
