Create the glue. Capture the protein. Eliminate disease.

De novo molecular glues for targets beyond the reach of traditional therapies.

OUR PIPELINE

Degrader programs built on deep biological insight and rigorous clinical translation.

SEED's pipeline is built for real-world impact, targeting diseases where standard modalities fail. Our lead RBM39 degrader (ST-01156) is in Phase 1 trials for Ewing sarcoma, hepatocellular carcinoma and other related tumors; complemented by 6 active programs supported by top clinical and strategic partners

OUR SCIENCE

More ligases. Rational matches. Better results.

While much of the field relies on only two E3 ligases, our RITE3™ platform unlocks access to more than 600 ligases encoded in the human genome.

Learn more about our science

RITE3 systematically identifies optimal ligase-target pairs and empowers them with custom molecular glues.

We discover E3 ligase–substrate combinations that were previously inaccessible, enabling a broader, more precise, and more rational approach to targeted protein degradation.
