A corollary of this and the OP's argument is that business-oriented CEOs with an idea that needs building have a lot more free time to carpet bomb prospective funders than engineers already building a product that needs more engineers to deal with the demand that's there. The idea that being too busy with product or customers to jump the hurdles they set could be a bad thing for funding doesn't reflect well on VCs (I'm the first person to argue the importance of knowing how to hunt for business is often underrated by engineers, but not every business needs networking oriented business developer types, and those that do are still better if they can dedicate more time hunting for intros to customers and less hunting for intros to investors)
