I mean, the default of any new company is pre-product-market-fit, no? How else could you start something new? During such an early stage much of your code may be written as a very rough MVP that you're only really using to validate a concept. Sometimes, you're going to just have to trash all of it because the idea was totally wrong and people don't actually care about the problem you're solving.

Those, among others, are the types of cases where spending extra time getting something exactly right (even if just a few hours) is just not worth it.
