My example is my own company, slicehost. I don't believe that we needed to find and/or prove the business model. It was a simple hosting model, we just thought we could do it more efficiently. Granted along the way new models arose from the automation inherent to the efficiency, but we already had profitability and traction at that point, it wasn't a requisite to 'making it'.
Now is efficiency gain (or conversely quality improvement) alone enough to make it qualify as a brand new business model? I'd argue that it is not.
My anecdotal support for my theory here is that we felt initially that we were taking very little risk in starting the business. It was clear and obvious to us that we could survive on the implied margins of other providers and acquiring customers in hosting at that point in time was relatively non-competitive.
