Lets help the 700 million people living without access to clean water. I decided to do this after my daughter and I were in tears listening to a podcast about a girl who donated her 9th birthday here.
I also love the business model. 100% of donations goes to providing water with the charity admin costs covered elsewhere and the fact that they've used tech to allow complete traceability of where your specific donation made a difference. If we can raise enough I'm going to visit where my birthday made a difference in 3 years time.
