In short:
Build-first is a mistake.
A good idea falls into a niche.
Do analysis: pain points, competitors, keywords, trends.
Paper and pen: develop 2–3 variations of the idea.
Choose one and build only the landing page.
Tell pain points and use cases.
Measure engagement.
Then build

In the spirit of #buildinpublic, I want to share a mistake I made.
I'll pay for it, but you can take home the juice.
I'm working on a framework, a pipeline to find, test, and validate ideas and engagement.
I'll share it as soon as I complete the puzzle.
