Interesting idea... I actually quite like the concept. I'm seeing this as more of an activist site than a sustainable business, though. What's to stop companies from just counting the respondents in their existing survey systems and just making their own donations?
I'm really glad you're propagating an idea that will raise a lot of money for charity, but I don't fully see how this can become a profit making business.
Nothing stops companies from doing their own survey system, and then counting responses and making charity donations.
However, this is a service already built to do that and it may save them the time and money to build their own.
Moreover, customer feedback often needs to be anonymous. So, if the company runs it, the customer may not feel as comfortable sharing their true opinion. A third party would be more desirable in those cases.
