Recently I presented a business proposal for starting a new sales based company to an investor, and he was interested in the idea. He decided to do some research on the idea of Marketing a sustainable product line. He then asked me to prove my connections for supply. I introduced him to my supplier by skype, and we had a meeting of introduction through conference call. My supplier said he would be able to fulfill the required amount, and offered terms and margins. This would be an international supply and demand business with the establishment of an exclusive brand, and many retail stores throughout. The investor then dropped the ball for months, and now has come back explaining that he has found an existing company he would like to actualize, and use my idea and supplier.(Lowest prices worldwide) I am not sure what he will offer to me as compensation for my part in bringing him into this idea, and using my supplier. My question is What is proper compensation for making this connection? Is it ethical for him to take my idea and connections? Should my supplier feel free to sell to him without my involvement?
