I ran four startup ideas through the same validation process. Three failed for the same reason.

Over the past few months I brainstormed four different startup directions — a real-world-asset tokenization platform for crypto holders, a DeFi trust/portfolio dashboard, an algo-trading agent, and a couple of narrower crypto tools (remittance, inheritance planning).

I ran each one through the same structured evaluation: business strategy, market sizing, financial logic, product scope, and risk, treated as separate lenses rather than one combined gut-check.

Three of the four kept failing for the same reason, and it wasn't the reason I expected. It wasn't "market too small" or "too competitive." It was that I could describe the product clearly, but I couldn't describe the person who currently feels the pain badly enough to switch. I had a solution shape before I had a specific, named person with a specific, current workaround.

The one idea that survived wasn't the biggest or most ambitious one. It was the one where I could actually picture the exact person, mid-workaround, annoyed enough to try something new.

What I took from this: running one idea through validation tells you if that idea is weak. Running several through the same process tells you what your personal blind spot actually is — mine was skipping straight to "what should this product do" before answering "who currently hurts, and how are they coping today."

Curious how others catch this before they've built anything: when you're evaluating your own idea, how do you tell "nobody has this problem badly" apart from "I just haven't found the person who does yet"?
