In carrying out my business, I come across many product and niche ideas that have huge potential online particularly Amazon. Is there a way I could go about selling these ideas online particularly to those who are at the early stages of wanting to sell on Amazon?
Absolutely! There are many online forums and mediums that are available that will allow you to sell product ideas online. I would focus in on free mediums first such as Reddit (forum), specific Facebook groups, and other like-minded websites that will allow you to sell some details of your niche.
Another way to do this is to reach out directly to Amazon sellers in similar niches or types of products and send them an email that you have an idea for X product in X industry and can provide them specific information that they will be able to profit from.
Warning: Ensure that you have "sold" the idea before providing all the details to the buyer. This way you can ensure that you are not giving away the idea and everything that comes with it, essentially for free. Ensure that you provide enough details to sell the idea (category, industry, what country, etc.) but be careful of the amount of details you provide.
