Negative feedback doesn't matter unless it's from customers (or potential customers). People tend to worry too much about negative feedback from non-customers.

Negative feedback doesn't matter unless it's from customers (or potential customers). People tend to worry too much about negative feedback from non-customers. A good example of non-customers eager to provide negative feedback is right here: HN :-) I've been running a SaaS for a couple of years now and learned to take all feedback from customers very, very seriously, but also largely ignore feedback from non-customers. As an example, most people who whine about your B2B SaaS being "too expensive", are non-customers. I did some experiments with discounts, these people inevitably leave anyway. Most real customers will give you feedback that is constructive, which immediately makes it positive. E.g. rather than whine or complain they will point out a missing feature or show how the software fails. So, while anxiety is very real (solo founder anxiety is a major issue), it should not come from negative feedback.
