Without some revenue, every company is on a direct course for disaster - by default. I think that the first pitfall some make is to look at investment money as revenue, cash coming in. But its a big giant fallacy.. it is not money from normal operations. Until you sell a product and have money coming in from it you are on borrowed time. This can be intentional and calculated position of building a product and bringing it to market when it is ready, but I get the impression that many don't plan or execute their way out of this fast enough.
