TechRadar - Mashable has an infographic pointing out that "only" 25% of Kickstarter projects deliver on time.

Sounds like the crowdfunding bubble is already bursting. Or is it?

Let's take a look at projects outside of Kickstarter. According to this report 33% of software projects are late. This one says that 75% of IT projects generally are late. And it might even be as high as 95%.

So Kickstarter projects are actually between 2 and 15 times more likely to be on time than other projects, at least in IT. (Kickstarter, Services)
