Mike Fitzgibbons

Mike Fitzgibbons is the CEO and Founder of Claritas Rx, a South San Francisco-based healthtech company that uses AI and real-world patient-level data to help biopharmaceutical companies track, understand, and support patients across the specialty drug treatment journey. Founded in 2011, Claritas Rx serves 20+ rare and specialty therapeutic areas and has appeared on Inc.'s 2025 list of America's Fastest-Growing Private Companies. Before founding Claritas Rx, Fitzgibbons spent seven years at Morgan Stanley as an equity research analyst covering pharma services and drug distribution, then joined Genentech where he worked on pricing strategy and led the Avastin marketing team - experiences that directly shaped his conviction that patient-level data, not aggregated reports, is what biopharma companies actually need.
