I get your point and provided a couple of examples of failed products. But there’s always another path. Depending on your personality, one approach is to take the people who complain and level with them. Yeah, this product sucks. It’s brand new. But does the problem exist? Is it important enough to you to want to solve?

If so, how can the founding team save the relationship? If someone is motivated enough to tell you your product sucks, they’re potentially great beta users!!
