The success of Airbnb and many others like it raises the interesting question - How many other billion dollar ideas, never got off the ground because investors thought they were awful ideas? We may never know. But it should give every entrepreneur something to think about and not be discouraged by rejections. Your idea does not need to be accepted by investors - only by the market! So if you really believe in your idea launch it and see if the market accepts it. If not tweak the parameters till it does. Build a minimum viable product and try to fail cheaply. If it works, investors will come running to you. A good way to look at it is that your startup is like an experiment and your product/service is the hypothesis you are testing. If it fails, your hypotheis is wrong - so change it and try again.
