Turning Personal Challenge into Innovation: Building Nulu – Doug Katz

Episode notes

What happens when personal challenge meets disciplined innovation? In this episode of Behind The Numbers With Dave Bookbinder, Dave speaks with Doug Katz, founder and inventor of Nulu, an adaptive kitchen knife designed for people with joint pain, limited mobility, or strength challenges. Doug shares a journey that spans West Point, military service, hobby knife-making, and the pivotal moment when his own physical limitations sparked a completely different way of thinking about kitchen tools. Doug walks through the invention and design process behind Nulu, including the inspiration drawn from the Ulu-style circular blade and the broader philosophy of task-based design — redefining disability by focusing on what people can do, not what they can’t. He explains why Nulu made a deliberate 360-degree strategic pivot back into the adaptive market and what that decision revealed about product-market fit. The conversation dives into the realities of building a physical product business: prototyping, protecting IP, offshore manufacturing, scaling challenges, fulfillment hurdles, and the importance of getting products into users’ hands through lending libraries and live demonstrations.
