Thanks to Michael and Elise for their comments. Although many investors will not be willing to invest in your product at this stage, getting a product to market is expensive. Different investors will invest in different markets at different times.
For example, consider the pharmaceutical industry. The whole concept of MVP doesn't really apply ... the value to investors is different. I suspect that you're not in pharmaceuticals, and that's not the point.
The point is that as a founder/CEO/leader, your job ... your primary responsibility is to make sure that all of the resources necessary to build your idea into a product and your product into a business. Yes, you can depend on the kindness of strangers and the 3Fs ... or you can hit the streets and find alignment with the right investors.
