Clarus Funds

Clarus Ventures was a premier life sciences venture capital firm that specialized in clinical-stage R&D investments within the biopharmaceutical and medical technology sectors. Founded in 2005 and headquartered in Cambridge, Massachusetts, the firm managed over $2.6 billion in assets across several flagship funds. Clarus was distinguished by its innovative investment models, such as risk-sharing partnerships with large pharmaceutical companies to fund late-stage clinical trials for specific assets. The firm's portfolio included numerous successful exits and companies that developed transformative therapies in oncology, cardiovascular disease, and orphan indications. In October 2018, Clarus was acquired by Blackstone to establish Blackstone Life Sciences, integrating its specialized expertise into a global investment platform.
