In today’s episode, I sit down with Zack Fleishman, CEO and operator behind Shark Wheel and a former pro tennis player ranked No. 11 in the U.S. We talk about how two non engineers used biomimicry and a sine wave design to reinvent the wheel, then turned early chaos into real traction. Zack explains choosing focus over fads, why agriculture became the breakout market, and how Shark Wheel generated more than $15 million in revenue without a sales team. We also cover equity crowdfunding, moving from R & D to sales, and the athlete mindset that carries through long roadmaps, failures, and the push toward a massive 2026 inflection point.
