Our favorite book is "Power Base Selling" by Jim Holden -- it's focused on high-end sales -- but will do a good job of getting you into the mindset.

I really encourage technical people (including founders) in companies to do this, it's highly educational about how the "real world" operates and how big businesses get built.
