Launching a crowdfunding campaign is a very public act, and creators put their reputations at risk when they do.
Investors 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. Entrepreneurs are encouraged to share links and as much background information as possible so backers can make informed decisions about the projects they support.
If the Entrepreneur has no demonstrable experience in doing something like their project or doesn't share key information, backers should take that into consideration. Does the Entrepreneur include links to any websites that show work related to the project, or past projects? Does the Entrepreneur appear in the video? Have they connected via Facebook?
Don't hesitate to request information from the Entrepreneur themselves. You can always reach out before pledging via the "Contact me" button on the project page.
