Our Mission
The Parsemus Foundation works to create meaningful improvements in human and animal health and welfare by advancing innovative and neglected medical research. The foundation’s focus is on supporting small proof-of-concept studies and then pursuing press coverage of the results, so that the advances change treatment practice rather than disappearing into the scientific literature. Many of the studies we support involve low-cost approaches that are not under patent. When supporting development of technologies under patent, the Parsemus Foundation coordinates with larger funders to make sure support is contingent upon strong public-sector pricing agreements.
