Image via CrunchBaseThere are five broad categories in tech: web tech, clean tech, bio tech, nano tech, fin tech. Each of those five categories are broad. Each has sub categories, and sub sub categories. There is no next Google in web tech, there is no next Facebook in web tech. Google is the next Google. Facebook is the next Facebook. But the Googles and Facebooks of clean tech, bio tech and nano tech are still out there. They are still small. If you can locate them and put some money into them, you are going to end up uber rich. But it is not easy to locate them, not easy at all. Even the Google of today was not easy to locate when it was small. Yahoo could have had the Google search engine for a few tens of millions, but they passed up on the offer.
