VCs love _technical_ risk. Outside of the very unusual circumstances of the Zero to One capital-funded-monopoly-theory era, they have considered _business_ risk quite toxic.
My point is that you state "VCs love risk" and I'm trying to help you clarify the way you think about this. VCs don't love _risk_ at all, they love _things that are an technical execution risk but would sell immediately if they can be done_.
Business risk stuff - does the market exist? is a new pricing model possible? etc. - is not at all on the list of risks that VCs like.
