"What else would validating include, apart from interviewing users" Interviewing (prospective) users would actually be a good start. Some of the B2C projects I worked on did not do this until after launch. B2B - I've worked on projects that did not have a single prospective client lined up before development started (let alone before MVP launch). I think there is a certain optimism entrepreneurs have in the face of rejection - sometimes it takes the form of "no one is interested right now, but we just need to have an MVP to show them and then they will become interested!"
