At first when the words was becoming popular, I was really wondering are these companies would bring new technology and change the current global market and industry, but when time went by, and things unfolded things hit a different road.
Some of their idea was actually really good on the paper and on head, but when they hit the market, sometime the demand and the way of thinking of the normal, and most people were not on the same thing then those they predicted on paper. There can be a lot of things, the change in the market, or social behavior, which is not the same thing as when they drew the road map and the business plan.
Also, the easiest to spot are some of those start-up are really trying to get the unicorn status by getting a lot of funding from the Venture Capital company so that they can hit the stock exchange, and then dumped the shares to the retail trader who will hold the bag, while the company going down and gone.
If you want to go even further, just do some fraud report on your company, so that the simple technology that you are giving as the base of the start-up that actually is not really work on real life, looks so promising and you can jack up the company to look big so that you get the funding as well as the prestigious title of the CEO and the Founder of Unicorn Starts Up.
it is all good and glory until the winds changes direction and your start-up starts to go down and sink.
