Crowdfunding is a method of raising finance from a large number of people who each contribute small amounts of money. It has grown significantly in recent years due to new online crowdfunding platforms. Crowdfunding can collect money through donations or loans and campaigns can be set up with an "all or nothing" or "keep it all" funding goal. Campaign creators offer rewards to backers and must consider the advantages of broader funding access versus the disadvantages of increased workload and intellectual property risks before starting a crowdfunding campaign.
