Mint.com: business plan in elevator pitch
http://www.slideshare.net/hnshah/mintcom-prelaunch-pitch-deck
As it was already mentioned before, you don’t need to have a solid multiple-page business plan for an early stage startup. Of course, it is not very convenient to write it on paper towels, but you can simply make it in the format of a presentation. As an example, I really recommend you looking at the Mint’s elevator pitch presentation, which actually has their business plan explained in 16 short slides. Why not make the same for your startup?
