Transforming the idea to a new Business (Startup) requires great passion in what you are doing, devotion in every aspect, inspired group of people that will support your idea (even rising-up on a higher level) and the right productivity tools that will streamline the way to success.
The most challenging part of all Start-ups is the limited budget at the beginning, so people with brilliant ideas did not manage to swim in the ocean full of sharks. Most of the time their ideas are stolen from some big companies which invest significant funds in the same project, deliver the product/service earlier on the market and start harvesting. The question is, who can survive???
