Hypothesis – “MVP in 2 Weeks”

I have tried out few ideas till now. Each of them have taken me at-least 3 months to come to conclusion that this would not work. I have always know that MVPs are the best way to validate an idea but I think 3 months is too long a time frame for validating an idea.

So I have a hypothesis - "Every startup's main value proposition can be tested in 2 weeks by a smartly designed MVP".

Am I right about this? If majority of you say yes, I will spend my brain next time to figure out the best way to design a MVP but till now I have not been sure so I end up spending a lot more than that.

Do suggest good ideas to create MVPs with examples. Few which I know are - 1. Landing Pages with wait-list (Dropbox, Robinhood) 2. Communities (Sharechat) 3. No-Code prototypes 4. Figma Prototypes
