Launching a Kickstarter is a very public act, and creators put their reputations at risk when they do.
Backers should look for creators who share a clear plan for how their project will be completed, and who have a history of bringing their creative ventures and other projects to fruition. Creators are encouraged to share links and as much background information as possible so backers can make informed decisions about the projects they support.
If a creator has no demonstrable experience in doing something like their project or doesn't share key information, backers should take that into consideration. Does the creator include links to any websites that show work related to the project, or past projects? Does the creator appear in the video? Have they connected via Facebook?
Don't hesitate to request information from a creator. You can always reach out before pledging via the "Contact me" button on the creator's profile.
