Interesting comparison on total funds raised:

Indiegogo campaigns were found to have raised far fewer successful dollars than [Kickstarter], with around $98 million total all-time, while Kickstarter had about six times that, or $612 million. Kickstarter has had 40 projects cross the $1 million threshold, with only 3 doing the same on Indiegogo, and Kickstarter’s average success rate is 44 percent, while Indiegogo’s is around 34 percent (which doesn’t take into account the many delisted projects that failed to raise at least $500. Including those delisted efforts, the previously reported 9.3 percent success rate on 142,301 total campaigns matches up nicely.

Much of the data was gathered by scraping the sites, so unsuccessful campaigns that are dropped from the site are not counted, but that shouldn’t make enough of a difference to change the apparent results.
