Hubbard’s expertise spans strategic vision, commercial acumen, and strong operational leadership.

Known for his mission-driven approach and ability to navigate complex markets, Hubbard’s leadership is expected to strengthen Flatiron’s growth trajectory and global influence in oncology research and care.
Starrett joined Flatiron in 2016, leaving behind a legacy defined by strategic focus and customer-centered innovation. Under her leadership, Flatiron Horizon, the company’s real-world data platform, expanded from 400,000 to more than 5.5 million patients. She launched the evidence services business, enabling biopharmaceutical partners to gain faster, more flexible insights, and oversaw the company’s expansion into Europe and Japan. The OncoEMR electronic health record system grew to serve more than 4,500 U.S. providers, and Flatiron’s data contributed to over 1,800 research publications, reshaping oncology care and research.

Reflecting on the leadership transition, Starrett said, “Leading Flatiron for the last four and a half years has been the highlight of my career. We are currently in an extremely strong position, and I have faith that the company will speed up its journey towards its full potential with Nathan at the helm. During his five-year tenure at Flatiron, Nathan has built our international business and presence from the ground up, broadened and strengthened our partnerships with leading biopharmaceutical companies, and played a crucial role in shaping our strategic vision.”

Flatiron plays an increasingly vital role in advancing oncology innovation, and I am confident that under Nathan’s leadership, the company will continue to shape the future of cancer research and care.”
