Matt damon's water crusade has helped 16 million people so far

Water.org co-founders Matt Damon and Gary White say conversations with investors about social responsibility are getting easier. The numbers prove it: Its WaterEquity impact fund — the

first-ever impact investment manager with an exclusive focus on ending the global water crisis — has grown to $60 million since it was created in 2017, and the charity has provided more than

16 million people throughout India, Indonesia, Cambodia and the Philippines with access to safe water and sanitation. One of the major barriers to safe water and sanitation is affordable

financing. Water.org addresses the barrier through access to small, easily repayable loans. According to Damon, it has provided 3 million loans that pay back at 99 percent. "Our model

is undeniable now," he said Thursday in an interview with CNBC's "Squawk Box" at the World Economic Forum in Davos, Switzerland. Within three years of its launch in 2009,

the organization had already reached its first million people with clean water, said Damon. "We're at 16 million now, so we are hitting a million a quarter now," he said.

Since the organization started, White has seen a real change. "A lot more corporations and brands are talking about working in social impact investing," he said. "Our first

visit here, we had the seed of an idea, like, 'Well, we think we can do this social impact fund and help get water to millions of people, and we came back two years later and we had

launched it. And now we came back this year and have $60 million of assets under management." Matt Damon and Gary White Source: CNBC He added: "What's exciting is that this

matters to consumers. The difference between now and four years ago is you hear these companies talking about all this social responsibility. They're not just saying it; their consumers

are pushing them in this direction." Historically, Water.org has partnered with foundations, financial institutions and brands rather than individual investors. Among them: Ikea

Foundation, Stella Artois, Pepsico Foundation, Caterpillar, Bank of America and the Conrad Hilton Foundation. Damon said he doesn't see this changing: "The problems are so massive

in dollar terms, you will never get there with philanthropy alone. You have to bring in the real money," he said. Damon is happy with the charity's progress. "We gave very

conservative projections. But we have these evidence-based models that pay back at 99 percent, so there really is a success story about just nudging the markets toward the most vulnerable

people, and it turns out they want to participate in their own solution."
