Not all products lend themselves all that well to sales though. Consider Google. How do you sell Google? You really can't have a sales team go out and try to get people to commit to using Google search. With a lot of companies the best you can do is let people know you exist and hope they'll use you. Sales in the traditional sense is a waste. To be clear, the kind of sales I'm talking about is the kind where you have people out on the road personally interfacing with decision makers, calling people (often they're cold calls), and generally reaching out to communicate with people one on one rather than putting up ads and getting exposure which is not sales but advertising.
