Three years had passed since the first time time I try to create a startup.

By that a protest at national universities was taking places, we haven't any class but a lot of free time, that sounds like the right place to start a business right?

After several ideas and some discussions we decided; a crowdfunding platform is the right idea, it will make us rich.

By that time there was an enormous hype about this platforms, or at least that was our impression, and not much people in the country was aware of this new technique of doing business, we can take a big part of the pie.

In retrospective several errors were make it.

The first one was to much talk, we spend an infinite amount of time discussing how far the project will get and which cool new features it will have.

Of course we were very cautious about talk with other people about our project, some one could steal our plan, so we received just a little amount of feedback.
