Most startup ideas don’t fail after launch — they were already weak before building

I kept noticing the same pattern: people spend weeks or months building something, only to realize later the idea was flawed from the start.

Not because they didn’t work hard — but because they didn’t pressure-test it early enough.

Most feedback you get is either too nice or too generic, so you move forward without really understanding the risks.

That’s what got me building Runtrix — an AI tool that tries to break your idea before the market does.

Still early, but I’m curious:

How do you personally validate ideas before committing to them?
