This is a very loaded question. In order to better answer the question is would be necessary to know more about the products or services, which markets you are considering, how you will get the information out, how you want to reach these groups.

I have worked with companies from all over the world, working on same or similar topics. There are hundreds and more groups and ways to penetrate the global market. Without more details, it is very difficult to help you further.

Let me know if you need more support. Goold luck.
