As Kickstarter campaigns have proliferated, so have flops. Take the Coolest Cooler, a campaign that raised more than $13 million, then told backers the cost to produce the cooler was larger than the amount they had been charged. Or Chicago-based Everpurse, which also ran into problems with fulfilling orders for customers and admitted they were "not very good at making bags." They later signed a deal with Kate Spade.
