I built a product business around an invented customer called Hannah. She never bought anything — because the standard ways of finding a customer don't work when you're selling something nobody needs. Here's what does.

The hardest businesses to walk away from aren't the ones that fail — they're the ones that almost work. Why you can't diagnose a stalled business from your own desk, and the call no spreadsheet makes for you.

Most operational chaos isn't designed — it accumulates, one workaround at a time. The clearest sign is where the work stops: at the one person everything waits on. Why hiring doesn't fix it, and what does.

The most uncomfortable kind of feedback is the one you can't argue with. Which is why founders keep choosing the validation methods that produce the blurriest signals. Blurry signals delay grief — and they delay decisions.
