15.3K citations, zero paying users. The missing piece wasn't marketing.

A year ago I was a liberal-arts grad who hated math. I taught myself Next.js and shipped a real product — a period-health companion I built because doctors dismissed my symptoms for 10 years.

I got good fast. SEO. AEO — answer-engine optimization. My content now earns 15.3K citations from Bing and Microsoft Copilot, still climbing.

Here's the part that humbled me: 15.3K citations, and almost no one paid. Not because the product was bad — because I never validated demand before I built. I built from pain, not from proof.

That was the whole gap. Not skill — I had skill. Not distribution — I had distribution. It was one unanswered question: continue, narrow, pivot, or stop?

So I built the tool I wish I'd had back then. BYB Mini Decision Aid — a founder-reviewed brief that puts evidence for and against a decision side by side, states confidence and unknowns, and gives a 7-day test with continue / watch / stop thresholds tied to your own numbers.
