I think without any consent it is not possible..
This is not about venture capitalists but you can take it like that. Suppose there is a company A which transfers its profit percent to company B's account without its consent. First of all Is it possible? Second, it is right? What will be the actions of company B, if it doesn't want that funding? and if company B accepts those funds what will company A expect from company B? And if A funded without permission, does it have any share in B's profit?
