Crowdfunding:Crowdfunding is the practice of funding a project or venture by raising small amounts of money from a large number of people, typically via the internet.
Backer: A backer is someone who contributes money to support a project on Kickstarter. They are like your cake-loving friends who chip in some cash to help make your cake happen.
Stretch Goal: A stretch goal is an additional target set by creators on Kickstarter beyond their initial funding goal. It's like adding extra layers and decorations to your cake once you've reached your original baking goal.
