If your goal is to raise money, then you has better make sure you have done your homework for the business reasons and justifications for the product or service.
The best business plans are summarized and laid out in the product or service demo.
I'm still not clear about what your definition of MVP is.
MVPs (product or service users that are loyal and passionate users or influencers) are typically used by large companies that want to generate positive marketing, spin, what have you for their product or service. You sell them, they sell others. Or, you pay them. Yada, yada, yada.
If you are writing here about a "most valuable product," then using the term MVP is silly. MVP indicates your other products are not valuable just based on the usage of that term. Avoid minimizing your products or services.
