I would argue that "no market need" is not one of the biggest reasons why startups/companies fail. Most startups fail because they fail to execute specifically within their market and/or find their product/market fit. So in other words, market is definitely there but there is failure in execution and inability to capture a decent market share. They try to sell to everyone which basically becomes you sell to no one (unless you are Amazon but that takes 20+ years of capital to survive and is outlier)
