Samuel Whitaker
Samuel Whitaker is the founder and CEO of Mural Health, a Philadelphia-area clinical trials technology company building a participant-first platform that bundles fee-free payments, transportation, two-way communication, and real-time satisfaction data. He invented the original participant payment tool, the ClinCard, when he founded Greenphire in 2008 and grew it into a billion-dollar company on roughly $2.2 million of outside capital. After a stint as CTO of Signant Health, he launched Mural Health in 2022 to push the same idea further: treating the trial participant, not just the sponsor, as the customer. He also drove the creation of the Harley Jacobsen Act, federal legislation to stop taxing payments to clinical trial participants.
