Paul Sargeant
Paul Sargeant is the President and CEO of Circular Genomics, a San Diego biotech building blood tests around circular RNA - the loop-shaped, unusually stable molecules most of the field once ignored. A Cambridge-trained physiologist with 25 years across Fortune 100 firms and venture-backed startups in the US, Europe and Asia, he took the helm in 2023, shepherded the launch of the MindLight test predicting which depression patients will respond to SSRIs, moved headquarters into Lilly Gateway Labs, and closed a $15M Series A in December 2025 to push the same platform toward early Alzheimer's detection.
Brad Kittredge
Brad Kittredge is the co-founder and CEO of Brightside Health, a San Francisco-based telemental health platform serving 135 million covered lives across commercial insurance, Medicare, and Medicaid. Driven by his father's decade-long struggle to find effective depression treatment, Kittredge built Brightside from a two-day old Stripe notification into the first telepsychiatry company to achieve 100% national Medicare Part B coverage. Before Brightside, he led product teams at 23andMe and Lantern, and built ComplexDx - later acquired by 23andMe. He holds an MBA, MPH, MA in International Affairs, and a BA in Psychology, all from UC Berkeley and UC San Diego.
