I'd be cautious about equity crowdfunding. If a company can't get funding through traditional means then the chances of them being successful aren't very high.
Just read the stories of shytty kickstarters to see why crowdfunding in general isn't a good idea (good for the company but not so good for the backers/founders)
A lot of times these companies are in over their heads and can't deliver the product in time. They end up taking losses because the economy of scales they thought were supposed to happen didn't. And also they don't know how to build a successful brand company past the initial "excitement phase" of kickstarter.

Kickstarter isn't equity crowdfunding.
