What is Crowdfunding?
Crowdfunding (a form of crowdsourcing) is the practice of funding a project or venture by raising monetary contributions from a large number of people, today often performed via Internet-mediated registries, but the concept can also be executed through mail-order subscriptions, benefit events, and other methods. Crowdfunding is a form of alternative finance, which has emerged outside of the traditional financial system. The crowdfunding model is based on three types of actors: the project initiator who proposes the idea and/or project to be funded, individuals or groups who support the idea, and a moderating organization (the “platform”) that brings the parties together to launch the idea.
