so much for 'spell check' - meant "multi" not mufti...

Recommend http://www.businessmodelgeneration.com/ = the mufti-functional resource for business modeling. Whether existing or at any point along the path - from start-up to blue-chip. Work thru the canvas from Value Proposition to Customer Segments and back and forth until the options are expanded - go to market with the MVP for startups - minimum viable product!
