Ridge Bio
Ridge Biotechnologies is a Bay Area startup using AI-driven enzyme and targeted drug design to build the next generation of precision medicines. Its platform pairs proprietary machine learning models with high-throughput, cell-free wet-lab experimentation to design enzymes and delivery systems for applications spanning antibody-drug conjugates, in vivo CAR-T, targeted nucleic acid delivery, biocatalysis and radiotherapies. The company emerged from stealth in September 2025 with an oversubscribed $25 million seed round led by Sutter Hill Ventures.
