Issue #26 — The 1-in-3 Market: You've Been Building for the Majority All Along
🎯 TL;DR
One in three U.S. adults now identify as neurodivergent, and 78% of neurodivergent employees already use AI at work — meaning "building for brains like mine" isn't a niche thesis anymore, it's a market-size argument. This issue shows you how to reposition your product's differentiation from "quirky preference" to "structural advantage in the largest under-served segment in professional software."
This week: Why the ADHD-friendly features you keep apologizing for are actually your moat.

🐘 The market you were told was a niche
Every ADHD founder I know has heard some version of this from an investor, an advisor, or a well-meaning designer: "Cool feature, but is that too narrow? Aren't you building for a really specific edge case?"
You've probably nodded along. Maybe you softened the copy on your landing page. Maybe you dropped "for ADHD brains" and replaced it with "for busy professionals." Maybe you buried the sensory-friendly toggle three menus deep because someone told you it looked "unprofessional." I did all three, in the same product, within the same six months. It was one of the dumbest sequences of decisions I've made — and I made it because I believed the market I was building for was small.
Turns out the market is roughly a third of the country. And the tell isn't just population share — it's behavior. The neurodivergent segment is the fastest-adopting cohort in the entire enterprise software market right now, and almost nobody in your competitive set is pricing that in.
📊 What the numbers actually say
Two data points changed how I pitch my company. The first is from a recent Inc.com feature by Netta Jenkins: roughly 1 in 3 U.S. adults now identify as neurodivergent — ADHD, autism, dyslexia, dyscalculia, Tourette's, and a widening umbrella of related profiles. That's not a rounding error. That's larger than the share of Americans who own a dog, larger than the share who have a college degree, and roughly the same size as the entire millennial generation.
The second data point is even more useful if you sell software. According to Allwork.Space, 78% of neurodivergent employees are already using AI at work — well ahead of neurotypical adoption curves. They're using it to draft emails they can't get started on, to summarize meetings they zoned out in, to rephrase Slack messages before RSD makes them delete a draft five times. In other words: they're doing your job as a founder for you, right now, with duct tape, because the market has failed to give them purpose-built tools.
Stack those two numbers next to the standard "vertical SaaS" markets that VCs happily fund:
| Segment | Approx. share of U.S. adults | AI adoption at work |
|---|---|---|
| Neurodivergent adults | ~33% | 78% |
| Small business owners | ~13% | ~40% |
| Remote-first knowledge workers | ~28% | ~55% |
| Left-handed adults (a real "niche") | ~10% | n/a |
If a segment is one-third of the adult population and the highest-intent AI adopter in the workforce, "niche" is the wrong word. The word you're looking for is underserved.
The strategic implication is uncomfortable for a lot of incumbents. Notion, Asana, Slack, Salesforce — every horizontal productivity tool over $1B in revenue was designed for a median user who statistically no longer exists in a plurality. They're serving the two-thirds and calling it "everyone." You get to serve the third they've been treating as an edge case, with product decisions they can't copy without breaking their existing users.
🛠 How to reposition without rewriting your product
You don't need a new product. You need to stop apologizing for the one you have. Here's the sequence I'd run this week:
- Rewrite your hero copy around the population, not the diagnosis. Instead of "for people with ADHD," try "built for the 1 in 3 adults whose brains don't fit the default." Same audience, ten times the perceived TAM. You're not narrowing — you're naming the segment your competitors won't.
- Put the neurodivergent-specific feature on the pricing page, not in the FAQ. If you have a focus mode, a sensory-friendly theme, a "just tell me the next action" button — that's not an accessibility footnote, that's your headline feature. Screenshot it. Caption it. Make it the thing prospects can't unsee.
- Quote your own users back at investors. One line from a user saying "this is the first tool that doesn't punish me for how my brain works" is worth six slides of TAM math. Collect three of those before your next pitch.
- Build one AI feature that removes an executive-function tax. Auto-summarize the thread. Auto-draft the awkward reply. Auto-break the vague task into three concrete steps. You already have 78% AI-native users — meet them where they already are instead of pretending AI is a novelty.
The move here is not to build a "neurodivergent product." The move is to stop pretending you're building a general one. Positioning is the cheapest lever you have, and most founders in your space are too scared to pull it.
⚡ The ADHD Angle
Here's the part that should feel like a cheat code: you have taste in this market that your competitors can't buy. When you designed the feature that lets users dump a brain-splatter of tasks and get back a prioritized list, you weren't doing market research — you were scratching the itch of your own executive dysfunction on a Tuesday afternoon. That's a moat. Every design decision a neurotypical PM makes about a neurodivergent user is a guess. Every one of yours is a memory.
The dopamine loop matters here too. Neurodivergent users churn out of "clean, minimalist" productivity tools at brutal rates because those tools mistake sparseness for calm and end up feeling like a blank Word document — dopamine-flat, motivation-flat, engagement-flat. You know instinctively that a satisfying checkmark animation, a streak counter, or a well-timed "you're crushing it" is not childish UX — it's neurochemistry. Your competitors think they're building software. You're building a scaffolding for a specific kind of brain, and that brain is now a third of the market.
🎯 This Week's Challenge
Pick one and finish it before Friday:
- Rewrite one page of copy (landing, pricing, or onboarding) to name the 1-in-3 segment explicitly. No hedging, no softening. Ship it and watch the conversion data for 72 hours.
- Interview three neurodivergent users about what they currently duct-tape together with ChatGPT to survive their workflow. Every hack they describe is a feature request with a validated buyer.
- Redo your investor one-liner to lead with the market number, not the mission. "1 in 3 adults, 78% AI-native, zero purpose-built category leaders" is a sentence that changes the temperature of the room.
See you Tuesday, L-P
P.S. — If you know an ADHD founder who's still apologizing for building the tool their own brain needs, forward them this issue. They're not niching down. They're aiming at the biggest under-served market in professional software, and someone should tell them.
