It is not enough to know that your clients want your product. You also need to know why they want it.
Because in business you cannot stand still and you have to constantly experiment with your offerings and your pricing models, you need to understand what exactly is attracting people to your products.
How you do that? Just ask them. Develop a strategy which allows you to constantly be in conversation with your clients (without imposing on their time), where you can subtly find out why they do business with you.
