Just a note : coming from the perspective of having helped launch a startup accelerator in Paris, I wanted to address a common misunderstanding about what MVP really is about.
Minimal Viable Product is *not* about minimal features set, or even UX design at all.
It's the minimal product that will allow you to learn about product/market fit. Said in another way, to learn if users/clients are at all interested, and are willing to make an investement (time, money) in your product.
It can be a landing page with a signup form.
It can be a couple of screenshots of the (not builded but shhh...) app that you present to potential clients.
Not every prototype is an MVP (because not every prototype is build to learn about product/market fit). Not every MVP is a simple product or a prototype.
