Although we hear of wildly successful crowdfunding campaigns, the truth is that the majority of these campaigns fail. The leading reward-based crowdfunding site, Kickstarter, has a 37 percent success rate and Indiegogo’s is even lower. And those cool hardware projects that seem to just take off and get immediate traction with backers? Don’t be fooled: According to research on completed hardware projects, 70 percent of those that raised over $100,000 on Kickstarter and Indiegogo added venture or angel investments before launching their campaigns.
