First of all, what is a MVP. This term often gets mistaken for a proof of concept or prototype. A MVP means Minimal Viable Product and it is where your product or website is developed with sufficient features to satisfy early adopters, ie it works and satisfies a need. This is where you build on to form your end product, all your market testing has been done and you can now develop your MVP into your product. A prototype is the sketch of your idea. The goal of it is to determine whether your idea could really go somewhere and what changes would get it further down that path. You get it in front of friends and family for small market validation, you can go to investors with it for MVP development.
