A lot of startup advice focuses on execution, but in my experience many failures actually start earlier, with the idea itself. Founders often fall in love with something that sounds clever but doesn’t map to a real, repeated problem.

The hard part isn’t building the product, it’s choosing what’s worth building in the first place. While searching on Google recently, I came across something called StartupIdeasDB, which is basically a curated database of a couple thousand startup ideas gathered from different corners of the internet.

What I found interesting is that it surfaces ideas tied to problems people are already discussing, rather than purely hypothetical concepts. When you look at ideas this way, you start noticing patterns of demand instead of chasing random inspiration.

It feels a bit like doing lightweight market research before writing a single line of code. Obviously a database won’t guarantee success, but it might help avoid the classic mistake of building something nobody actually needs.

Curious how other founders here validate an idea before committing months to it.
