Think about this for a second – if your prototype or MVP is very well designed, it might in fact be trickier to get objective feedback from potential users. They are bound to get distracted by the beautiful design, and subconsciously base most of their feedback on how it looks/feels rather than to tell you if the core of your product is worthy and solves a real, genuine problem for them.

Design is important, but the timing to focus on it is more so.
