ADHD - Disorder or Societal Disconnect
ADHD is often framed as a disability. I personally do not feel that way. For some people, it is—but that experience is shaped heavily by environment. There are theories that different cognitive styles evolved for different roles—some oriented toward structure and order, others toward movement, adaptation, and uncertainty. Both are valuable. But modern systems tend to reward only one. When the environment aligns with the wiring, performance changes. This is about ability—and f

Entrepreneur of Impact 2026 - Round 1, Day 4
One of the things I committed to during this competition is showing—not just telling—the impact we’re making. Today, that impact is about access. Across the country, there’s a network called the Assistive Technology Act Technical Assistance and Training Center (AT3). Through this network, each state has a demo or lending library where people can try assistive products before they buy them. That matters more than most people realize. When someone is dealing with a physical li

When the "A" in AI Also Means Adaptive
We need to start thinking about what can go right with AI and who it can help. Much of the public conversation about artificial intelligence revolves around replacement. The argument tends to fall into one of two camps: either AI will replace human thinking, or it will diminish the value of human work. The framing assumes that the central question is substitution. But from where I sit, that isn't the most interesting aspect of what these tools are doing. The more compelling d

On Aging, Aikido, and Adaptation
Sometimes in life, roads don’t fork. They intersect. Recently I stepped back onto an Aikido mat after several years away. Within the first few training sessions — most of which ended with me on the floor, where I seemed to be spending more time than I remembered — I realized something that should probably have been obvious much earlier. Getting up after being thrown took longer than it used to. A lot longer. And the getting up was just the beginning. I also found immense j

Traditional knife systems, with multiple tools requiring frequent maintenance, create inefficiencies and risks that can disrupt operations. The NULU knife offers a groundbreaking solution by consolidating six traditional knives into one ergonomic, versatile tool. Coupled with a tailored sharpening subscription service, NULU provides measurable productivity gains, cost s

Maximizing Efficiency and Ergonomics Through Optimized Force Transfer Geometry in Knife Design
Introduction The design of cutting tools is central to effective food preparation, directly impacting not only the efficiency of tasks but also the user’s long-term comfort, safety, and overall experience. For many individuals, particularly those with upper extremity limitations or mobility impairments, traditional knives can be a source of strain and fatigue due to the physical effort required to perform common cutting tasks. Because inefficient cutting can actually contribu

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

The Ability Curve: We Will All Be Disabled Eventually
We all move along the Ability Curve. Designing for each other means designing for ourselves — now and in the future Biology Always Wins: The Reality of the Ability Curve We don’t like to think about it, but here’s the truth: You will be disabled someday. Maybe not today. Maybe not tomorrow. But eventually, biology catches up to all of us. It could be an injury. A chronic illness. Aging joints. Shaky hands. Slower reflexes. Lost strength. It happens to everyone — not because w

1.3%
1.3%. It’s not the interest rate on a financial product, it is not the number of bikers that are kind of outlaw and it is not the percentage of daily nutrition from your cereal. It’s the percentage of your life that each year represents in a 77-year lifespan-the average lifespan in the United States, according to the CDC. I’ve been reflecting on this a lot lately: my age, these uncertain times, and the many things I still want to accomplish. Each passing year feels more signi

CH 16 - From Soldier to Blade Maker: How Veteran Doug Katz Forged NULU Knives from UNSCRIPTED BRILLIANCE The PodMatch Edition by Adrienne Barker, MAS
I was recently honored to be highlighted in Adrienne Barker, MAS's recent book, where she profiles entrepreneurs building businesses that solve real problems in unexpected ways. The chapter tells the story behind the NULU—a kitchen knife born from a moment of frustration in my workshop. "Disability and ability is a continuum. It's not an identity. It's not a different tribe... We all will get there. The reality is people look at disabilities and identity as opposed to a state
