I would like to know if there is any other distinctive crowdfunding model other than the four basic crowdfunding models that include donation-based, reward-based, equity-based, and debt-based models? Excluding the hybrid, of course.

Hello Kiko, 

There is also revenue-sharing and royalty crowdfunding. Those two are similar but each has its own nuance depending on how you structure your unique deal. 

Just keep two things in mind: 

1. Investors will want good investment terms 

2. Crowdfunding doesn't actually raise you money, marketing does. Gotta market your deal.
