Interestingly when I created one of my start-ups in 1999- I was ( naively) convinced based on the emerging explosion of the fairly uncharted internet, that we would create a $1m dollars in on line revenue. Truth be told almost $0- however 2015 is a completely different beast and it would be very detrimental to any business to not explore the relevance of interest sales as it relates to your business.
