Leash

Leash Bio is an AI-native biotechnology company building a massive proprietary dataset of protein-molecule interactions to transform drug discovery through machine learning. By screening millions of compounds against thousands of proteins — generating over 30 billion measured interactions — Leash creates the training data needed to power advanced ML models capable of designing better drugs faster. The company's automated lab platform continuously screens hundreds of pure proteins against millions of AI-designed molecules in cycles of a few months, enabling rapid identification of drug candidates for oncology and other disease areas.
