Ask HN: Has finding more competitors ever made you more confident?

I was researching the personal finance market and initially found only a few obvious companies.

After digging more, I found a much longer tail of startups I’d never heard of, including products that launched, got some attention, and then seem to have faded out.

Oddly, that made me more interested in the space, not less. It made me think that competition by itself isn’t the important signal. The more useful question is why so many attempts failed to differentiate.

Do people here look at the “graveyard” when evaluating an idea, or mostly the current winners?
