Here's an article that has high value because it is clear, simply written, and extremely accurate. it's all about what kind of sales team to create for your startup. The point I liked the best was the fact that in the beginning it is the founders who need to do the selling, so you can get a feel for what's out there. The second point also really rings true: don't hire a sales manager, hire someone to sell, as you need the sales. This is a good read.
