About the Founder
Hi, I'm David 👋
A father of children with autism — and the story behind why Winnowfi exists.
My Story
I'm a father of children with autism.
Every month, our family navigates a maze of subscriptions — therapy apps, specialized educational tools, communication platforms, support services, and work tools. I kept losing track of what we were paying for, what was actually being used, and what was silently draining our account.
I built Winnowfi for my family. A simple, clear way to track every subscription, get notified before renewals, and understand exactly where our money goes.
But I wanted it to mean something beyond personal convenience.
20% of everything Winnowfi earns goes directly to autism research— to the scientists working every day to understand why autism happens, how it works, and how to make life better for the millions of children and adults affected worldwide. When you use Winnowfi, you're not just organizing your finances. You're helping build a better future for families like mine.
Why I Built Winnowfi
A father's problem first
My sons have autism. Managing their care means juggling dozens of specialized apps, therapy tools, and support services. I built Winnowfi because I needed it — and couldn't find anything good enough.
A problem millions share
The average person has 12+ recurring subscriptions and loses hundreds of dollars a year to forgotten charges. This isn't hypothetical — it happened to me and everyone I talked to.
A chance to do something bigger
I realized early on: if this product is useful, it can also be meaningful. 20% of everything Winnowfi earns funds autism research. Your subscription tracker does more than save money — it funds science.
My Vision for Winnowfi
I want Winnowfi to do two things that reinforce each other: give people clarity and control over their subscriptions, and channel that success into something that matters beyond the product itself.
"I want Winnowfi to do two things: give people control over their subscriptions, and channel that into something that matters. 20% of our revenue goes to autism research — not as a marketing tactic, but because it's the reason this product exists."
