Scott Harrison is awesome. He also happens to be the founder of Charity:Water.
What I really like about it is:
1- they reinvented giving: charity (contributions) vs water (donations)
2- they SHOW you exactly what your money does. and lets you track it.
3- how they focus on a tangible thing like WATER but the benefit is an intangible one, like HEALTH > he tells a story with a BRAND.
