Crowdfunding is the practice of funding a project or venture by raising many small amounts of money from a large number of people, typically via the internet on specifically designed platforms and is an alternative to traditional ways of raising finance. The model is usually based on three parties: the project initiator who proposes the idea or project to be funded, individuals or groups who support the idea, and a moderating organisation (the “platform”) that brings the parties together to launch the idea.
