Crowdfunding platforms like Kickstarter and Indiegogo connect people looking for founds with thousands of other people. An outstanding example was in 1985, the call on 1400 Australian investors by Paul Horgan and John Cornell to help them produce their film Crocodile Dundee.
There are 4 types of crowfunding : Equity-based (Angelist and Circle up) where people can sell shares in their company.
Debt-based : Loan sites between individuals to repay debts (Lendingclub).
Reward-based: Donors support campaigns that interest them in exchange for receiving something in return like Kickstarter.
Donation-based: Charitables platforms that collect money for nothing in return.
All these forms of crowfunding help businessmans and investors around the world.
