I'll second the lack of information about playbooks/ running a middle-class company. It's a bit frustrating that everybody assumes you want to follow the VC model. Probably the most common question I get is when I'm going to sell the company - not realizing that we're a profitable company that doesn't need an exit. I also think middle-class companies are under-reported on. I have to assume that there are a lot of companies like us but it's not as sexy of a story: slowly and steadily building a successful business.
