People back projects for a number of reasons. They may be rallying around a friend’s project, or supporting a new effort from someone they’ve long admired. They might be inspired by a new idea, or simply motivated by a project’s reward.
Whatever the reason, people back projects because they want to have a part in helping to bring it to life. Backing a project is more than just pledging funds to a creator, it’s pledging support for a creative idea.
