Core in the Kitchen: The Kinetic Chain and Knife Use
The traditional chef’s knife, celebrated for its heritage and versatility, may actually be working against the user — particularly when it comes to force efficiency, safety, and long-term strain. Most conventional knives demand a full grip, forcing users to stabilize and drive the blade entirely with their hand and wrist. This not only reduces cutting power but also isolates force in the smallest and most fatigue-prone muscle groups in the upper extremity. In contrast, NULU’s

Seated Doesn’t Mean Stuck:Addressing the Biomechanical Challenges of Cutting from a Seated Position
Introduction: The Seated User is the Forgotten User In kitchen design and tool innovation, one key group is consistently overlooked: seated users. Whether due to disability, age, fatigue, or injury, millions of people prepare food while sitting. Yet the tools they rely on—especially kitchen knives—are largely optimized for standing use. This disconnect between user need and product design creates unnecessary strain, exclusion, and even danger. The humble kitchen knife is a pe

ADHD Is a Gift — But Only If It’s Tethered Correctly
I wasn’t surprised when I was diagnosed with ADHD. I had known for years. The diagnosis didn’t reveal something new about me; it confirmed something I had already been living. The intensity. The jump-cut thinking. The friction with monotony. The ability to feel underloaded in stable environments and sharply alive when stakes rose. What changed wasn’t the label. What changed was perspective. For most of my life, ADHD functioned as an explanation for inconvenience. It explained

The Hardest Part of Building in the Adaptive Space Isn’t the Product
When I first got into the adaptive space, I figured the hardest part would be design. Adaptive products, after all, carry real responsibility. They have to work for people who don’t have the luxury of trial-and-error, who aren’t looking for novelty or marginal improvement, but for something that meaningfully changes how they move through the world. I was wrong. Design was hard, but it was solvable. What surprised me — and what continues to surprise a lot of founders and organ

In a World of Slugworths, Be a Wonka
Entrepreneurial lessons from Willy Wonka and the Chocolate Factory or making good in a wary world. There are very few movies that feel universally beloved—not just popular or successful, but beloved. Willy Wonka and the Chocolate Factory is one of those rare cultural touchstones. I've never met anyone who actively dislikes it. That alone should tell us something. It isn't just nostalgia. It isn't just Gene Wilder's performance or the songs or the candy. It's what the movie sa

Revolutionizing Kitchen Tools: The NULU Experience
We’re a small startup, and we take every bit of feedback seriously — sometimes personally. When you spend years developing something you believe can genuinely help people, criticism hits differently than you’d expect. A recent Amazon review stopped me in my tracks. The reviewer called the NULU “an overpriced pizza cutter,” “irresponsible,” and even predicted it would end up “in evidence bags more than kitchens.” I’ll be honest — that one stung. Not because it was harsh, but b
