A project is a finite work with a clear goal that you’d like to reach.
A campaign is the fundraising period and related activities for the project
The funding goal is the amount of money that a project creator needs to complete their project.
A Project creator or Project owner is the person or team behind the project idea, working to bring it to life.
Backers, Supporters or Contributors are folks who pledge money or donations to join creators in bringing projects to life.
Rewards are a creator's chance to share a piece of their project with their backer community. Typically, these are one-of-a-kind experiences, limited editions, or copies of the creative work being produced.
