On this episode of The Kara Goldin Show, we’re joined by Charlie Melvoin, Co-Founder of Zygo—the world’s first and only underwater streaming headphone that’s transforming how we think about swimming. With bone-conduction technology and real-time audio streaming, Zygo is bringing connection, coaching, and community to a workout that’s traditionally been silent and solitary.
During our conversation, Charlie shares how he and Co-Founder Sheera Goren built a first-of-its-kind product in a space that hadn’t seen innovation in decades. We dive into the wild journey of launching a hardware startup, the unexpected challenges of building tech for underwater use, and what it takes to create a new category in fitness. From investor conversations to user behavior to the future of sports tech, this episode is packed with insights for founders, builders, and fitness fans alike.
Whether you're a founder or a consumer interested in the next thing in innovation, this episode is packed with insights you won’t want to miss. Now on The Kara GoldiShow.
