Dan Lievens
Dan Lievens is the CEO and founder of Share One, an Austin-based platform that turns real customers into on-camera storytellers through human-led, verified video testimonials. A serial entrepreneur who has started 11 companies across technology, finance and wellness, he built Philadelphia's first coworking space before turning to the question of how brands earn trust. Share One closed a Series A round in September 2025 to expand its engineering and editing capabilities.
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.
Ted Mann
Ted Mann is the co-founder and CEO of CollX, a Haddonfield, New Jersey app that lets collectors photograph a trading card and get its market value in under a second. A serial founder who built the couponing app SnipSnap (sold to Slyce for $6.5M) and later ran Slyce/Partium, Mann turned his kids' love of card trading into a business with more than 3 million users, a booming in-app marketplace, and a $10M Series A backed by sports figures like Eagles GM Howie Roseman, 76ers owner David Adelman, and MLB star Bobby Witt Jr.
