Our project -
https://www.kickstarter.com/projects/th ... -edinburgh - is 91% funded in just over ten days, but we have found that it is the majority of our friends who have been backing us rather than total strangers.
Having said that we haven't made a fully concentrated effort to get the project out into the world as other people may have. What has helped though is that our project has a cast and crew of nearly 40 people, so our target base was very broad when we started out. We can only imagine how hard it must be to crowdfund a project on your own.
