Overview

Aditum Bio is a biotech venture capital firm founded in 2019 by Joe Jimenez, the former CEO of Novartis, and Dr. Mark Fishman, the former President of the Novartis Institutes for BioMedical Research. The firm is headquartered in Oakland, California, and has quickly established itself as a key player in the biotech investment landscape. Aditum Bio focuses on improving patient outcomes by efficiently identifying and developing potentially first- and best-in-class therapies.

The firm operates with a unique company-creation model that allows for rapid formation and execution, advancing novel drug candidates into clinical trials. Aditum Bio has launched a total of 13 companies to date and is currently deploying capital from its third fund, which closed in early 2025 with a size of $428 million. This growth in fund size reflects increasing confidence from limited partners in Aditum Bio's investment strategy and operational capabilities.
