In the event that you aren't talking about equity or royalty crowdfunding, but a regular site I would strongly urge you to stay away from IndieGoGo. They are great for charity and design but when it comes to business funding campaigns hardly come close to their goal let alone meet it. If you decide to use a business crowdfunding site I would recommend you offer royalty based funding rather than equity since you will retain 100% of your company and will only pay royalties for a limited amount of time. Hope this helps. I don't typically offer crowdfunding help but I am an expert in marketing and launching startups. Please feel free to setup a call if you have any other questions.
