JAZZ is a venture capital fund built entirely around "Human Performance" that invests only in technologies optimizing human health, productivity, and well-being, with a core thesis explicitly tying advances in neuroscience and brain science to behavior change through products where neurological and cognitive science are built into the mechanism of action. The team includes practicing scientists, neurosurgeons, and technologists—including a former board-certified neurosurgeon, a UCSF neurology professor, and former Google Cloud AI R&D head—giving them primary research insight and technical diligence depth that most generalist venture firms lack.
