Caribou Biosciences is a clinical-stage biopharmaceutical company founded in 2011 by pioneers in CRISPR genome editing and headquartered in Berkeley, California. The company’s mission is to develop innovative, transformative therapies for patients with devastating diseases through novel genome editing. Caribou leverages its proprietary technologies to develop a wholly owned pipeline of genome-edited, off-the-shelf immune cell therapies, including CAR-Ts and CAR-NKs, for the treatment of multiple different types of cancer. Caribou believes that advanced genome editing is necessary to develop sophisticated cell therapies to treat a variety of malignancies.


Members of the Caribou herd open their minds to new ideas and welcome diverse perspectives. We proudly assert that teams do their best work when their members are personally engaged, their ideas are taken seriously, their contributions are recognized, and their needs are met.
