Most of what I've written about our mission is about where the money goes: 20% of WinnowFi's gross revenue funds autism research, with receipts published every month. That's the visible half. This post is about the quieter half — how autism shaped not just who we donate to, but how the product itself is built.

Autism is not rare. The CDC's Autism and Developmental Disabilities Monitoring Network reported in 2025 that about 1 in 31 eight-year-old children in the US were identified with autism spectrum disorder (based on 2022 data). That's millions of individuals and families — and almost no financial software is designed with them in mind.

The hidden tax of financial admin

Managing money is mostly attention work. Remembering which services renew and when. Scanning statements for charges you don't recognize. Decoding a merchant string like "SP*SPOTIFYUSA877". Deciding, over and over, whether something is still worth paying for.

For many autistic people — and plenty of non-autistic people — this kind of open-ended, ambiguous, always-on admin carries an outsized cost. Executive function differences are one of the most consistently documented aspects of the autistic experience, and financial upkeep is executive function work in its purest form: unstructured, recurring, and full of surprises.

Surprise is the key word. A charge you didn't expect isn't just an annoyance; for someone whose baseline stress rises with unpredictability, it can wreck a day. Traditional money tools respond to this by showing you more — more transactions, more graphs, more alerts. We think that's backwards.

Predictability is a feature

WinnowFi's core design goal can be stated in one sentence: nothing about your recurring money should ever surprise you.

That goal turns into concrete product decisions:

Renewal alerts arrive 7 days before the charge — enough time to decide calmly, not react after the fact.
Price increases are flagged the moment a subscription starts charging more than it used to, so drift never goes unnoticed.
One clear monthly total sits at the top of the dashboard. Not a projection, not a score — the actual sum of what your subscriptions cost per month.

Why WinnowFi doesn't show you a transaction feed

Here's a deliberate absence: WinnowFi will never show you a wall of raw bank transactions. Our detection engine reads them so you don't have to, and what you see is the distilled result — a short, plain list of your subscriptions, each with a name you recognize, a price, and a next billing date.

This is partly a privacy stance (the less financial data we surface, the less can go wrong) and partly a cognitive one. A transaction feed is homework. A subscription list is an answer. If a tool's job is to reduce the mental load of money, it shouldn't start by handing you 400 rows to scroll through.

The curb-cut effect

Curb cuts — the little ramps where a sidewalk meets the street — were fought for by wheelchair users. Then everyone else discovered they're better for strollers, luggage, delivery carts, and bikes. Designing for a specific need produced something universally better. Accessibility researchers call this the curb-cut effect.

The same applies here. Plain numbers instead of jargon. Alerts before charges instead of after. No guilt mechanics, no streaks, no shame-driven notifications — just information, in time to act on it. These choices are made with autistic users in mind, and every single one of them makes the product better for everyone.

The mission, both halves

So yes — 20% of every dollar WinnowFi earns goes to autism research: 12% to SPARK for Autism and 8% to the Autism Science Foundation, with signed receipts on our Transparency page. That half of the mission is easy to point at.

The other half is harder to see but just as intentional: building the calmest possible money tool, for every kind of mind. If you want the full story behind the pledge, it's on our About page.
