Hipster apps are not enough.
It is better for example to create some social mobile games, and then get valuated in a crazy bubble.
For example the company Gungho, they got 273 million invested on them at march for about 60% of the company (do not remember the exact number), then released a single game named Puzzles and Dragons, and now they are valued on the Tokyo Stock Exchange for about 15.1 billion USD yay!
And yes, that is more than Nintendo, for a single game. Perfect example of investor rationality.
