I am organizing and promoting an online training on developing communication skills. Now I want to give away materials of my training to third party companies so they can use it with their clients. It's going to be free at the very beginning but I want them to donate money for use of my training materials but it's not mandatory. Later on I am going to modify the agreement to charge commissions for use of my concept.

What is the right term for this business model?

Affiliate program? Franchise?

Thank you
