One of the "golden rules" of investing we have at our firm, Cue Ball, is that we value the business model over the financial plan. In fact, we value the business model over any particular sector for investment and like to say that we are "business model driven" (versus sector-driven). There is not necessarily a consistent definition for business model, but the Wiki definition is good enough. It says a business model is "the rationale of how an organization creates, delivers, and captures value." Consistent with this definition, we see the business model as the explanation of how a firm translates an idea into value, or more bluntly, into money. There is no doubt that at the heart of a business model is the monetization model. Over the years we have learned that having a business does not necessarily mean that you have a business model. Think of the dot-com heyday, when shipping 89-cent pet foot in an $18 Fed Ex package was a business.
