On this episode of The Kara Goldin Show, we’re joined by David Istier, Founder and CEO of gutzy Organic—the functional food brand on a mission to close America’s massive fiber gap and bring gut health to the forefront of wellness. With only 5% of Americans meeting the recommended daily fiber intake, David is leading the charge with clean, convenient snacks that make it easy—and enjoyable—to take care of your gut.
In our conversation, David shares the inspiration behind launching gutzy, his journey from helping scale GoGo SqueeZ into a billion-dollar brand, and what it takes to build a food company that’s not just trendy but truly transformative. We explore the science behind prebiotic acacia fiber, the importance of functional food in public health, and how gutzy is helping shift cultural attitudes about digestive health—one pouch at a time. He also gives us a behind-the-scenes look at the challenges of educating consumers, staying mission-aligned, and scaling smart in a competitive category.
Whether you're a wellness-focused consumer, a founder in the CPG space, or someone who cares about what goes into your body—this episode is packed with insights you won’t want to miss. Now on The Kara Goldin Show.
