According to Kickstarter's own metrics (and I'm sure we agree that they're the clear winner in this space), there's been a total of about $1.5B in funds raised TOTAL, over the lifetime of the site: https://www.kickstarter.com/help/stats
So it's not even close to being close. Maybe there's 3x more crowdsourced projects funded than companies backed, but most KS projects are funded for a few thousand dollars.
