Crowdfunding is the umbrella term for all forms of financing by a large number of small investors such as Crowdfinancing, Crowdinvesting or Crowd Lending. The classic form of crowdfunding consists of many small investors getting together on an Internet platform and investing in a project, for example, the development of a product.In return, they do not necessarily get a return on their investment but may get the resulting product given for free or at a discounted price. There is also the form of donation crowdfunding, which raises money for a good cause.
