All it needs is an idea to start a business , along with a solid team and a network. In these days, when we come across statements that " ideas are everywhere and it is only execution that matters", it is heartening to come across examples like Paul Hartunian , Alan Francis who with the sheer power of their idea created million dollar businesses. One came up with a idea of mass selling Brooklyn bridge and othe sold a book with blank pages !. Both are examples of the importance of IDEA per se.
