Ask HN: Which one is the primary reason why startups fail? (Choose from two)

1. You built something that nobody wants. 2. You couldn't find the right people who needed your product.

Which one is more critical? I believe the 2nd one is more impactful than the first one?

Often, startups fail even before they could say "We built something that nobody wants." because, they weren't able to reach out to the people who needed their product?

What is your opinion?
