But wait, you say, look at eBay, Amazon, and Craiglist – they look like crap. Implement an MVP with product/market fit, and it doesn’t matter what it looks like. That’s true sometimes, but it also depends on where you are on Maslow’s hierarchy of needs. The lower on the pyramid your product is, the crappier it can look. If your product is core to helping people make money, pirate movies, or sell your useless couch, you don’t need a designer. But if you’re high on the pyramid, ugly/clunky UI makes it impossible to for people to see your vision.
