Leonardo Gannio
Leonardo Gannio is the founder and CEO of MAGIIS, a Miami-based mobility-as-a-service platform for transportation-for-hire operators. A serial entrepreneur born in Buenos Aires, he built the technology distributor AKTIO Group into a $500M, seven-country business before selling it, after corporate stints at NCR, Informix, PeopleSoft, Lexmark and Ingram Micro. He is the author of 'Mobility 3.0: How to Win and Thrive in the Future of Passenger Transportation' and a keynote speaker who casts the future of mobility as electric, autonomous, connected and personalized.
Cody Simmons
Cody Simmons is the co-founder and CEO of DermaSensor, a Miami-based medical device company behind the first FDA-cleared, AI-powered handheld tool that helps primary care physicians evaluate skin lesions for cancer in seconds using elastic scattering spectroscopy. A bioengineer with a Brown degree, a Stanford master's and four years at Genentech, he took over the company in 2016 and spent nearly a decade shrinking a microwave-sized prototype into a point-and-click device, navigating FDA breakthrough designation, a De Novo clearance in early 2024, and a $16M Series B in 2025.
Zak Ringelstein
Zak Ringelstein is the co-founder and CEO of Zigazoo, a moderated, kid-safe social network often described as the antidote to TikTok. A former public school teacher and Teach For America alum, he built and sold his first edtech company UClass to Renaissance Learning, ran a left-insurgent 2018 U.S. Senate campaign in Maine as the only DSA-endorsed major-party nominee, then launched Zigazoo with his wife Leah during the pandemic. The company has raised roughly $26M total, including a $17M celebrity-studded Series A, and made headlines when Australia exempted Zigazoo from its sweeping social media ban.
