This sounds great. We already use https://percentpledge.org though. How is this different?
We invite our donors to give into their own charitable fund, and support specific organizations when they feel like a strategic opportunity has arisen. Donors are more satisfied when they can give bigger on things they are really passionate about.
Percent Pledge also has a 5% fee on every dollar given through them. We have no fee. 100% of your money goes to the charities you support. We want to eliminate fees from giving!
