Quoted from yuriijos:
Just curious, since the goal amount is already reached and over the amount, does the originator get to keep all excess funds?
There's not really any excess here. Nearly everyone who bought in is getting something in return so the money is going towards that. The goal amount is basically "it would take this much money to make it feasible/worthwhile to create this item and sell it" and anything over that means more items are sold. I don't have any affiliation with this company nor have I run any Kickstarters, just backed a few and hope I understand how it works.
With some sites, like gofundme, you're often just giving money for someone's (possibly non-commercial) project with only token rewards offered (in which case I assume they do keep the excess) but this is quite different.
