I work at a VC firm and can second this. It's not terribly important for B2B companies, though it rarely hurts. But it's pretty important for B2C/Ecommerce companies. Customers don't grade on a curve and the bar for minimally acceptable design is pretty high these days. If your deck doesn't signal to the investors that you have strong design/branding instincts, be prepared for a tough sale.
