Browsing in the Internet I have found different websites that point a different number of crowdfunding types.
All website use 3 types in common:
1. Equity Based Crowdfunding: Investors receive a stake in the company.
2. Lending Based Crowdfunding: Investors are repaid for their investment over a period of time.
3. Reward Based Crowfunding: Investors receive a tangible item or service in return for their funds.
But there are other websites that uses another type:
* Donation Based Crowdfunding: Contributions go towards a charitable cause and there is no reward for the funders.
