Where does the name iguacu come from?

iguacu means “big water” and is also the name of a great river and a beautiful, huge waterfall in South America. Our name is our vision. Think of each of us as a drop of water, and think of the difference we can make together, acting effectively, to help where the need is great.

iguacu is to become synonymous with the power and joy of effective giving. We are excited together to see our community grow. Join us today, we are iguacu.

What’s the difference in giving via iguacu rather than directly to a charity?

Many international charities today present an appeal for a crisis, and when you donate, you actually donate either entirely or partially to their global operations, or their operations elsewhere. Sometimes for very good reasons. However, at iguacu, your donation is restricted to the charity’s operations in the relevant crisis because this is where our network has identified their operations as being highly effective. You are also part of a growing community who wants to collectively channel large scale effective public action to where the need is truly great.

When was iguacu first established?

iguacu was established in 2014.

Tell me more about your expert network?

For every crisis we cover, we build an extensive network of strategic and on-the-ground experts who come from humanitarian non-governmental organizations, United Nations agencies, development agencies, private sector initiatives, academia, research institutes, community associations, local government and more, depending on the crisis. We speak to those best placed to know the changing realities on the ground, the major humanitarian challenges and which are the genuinely effective actors addressing at least one of these challenges. We take the time to draw from as many different perspectives as possible before getting to a recommendation. Though all our experts have demanding schedules, and are sometimes working in very challenging conditions, they take the time to speak with iguacu. Our entire network gives their time for no fee.

What if I want to get a donation refunded?

We, in common with all registered non-profits with 501(c)(3) status, are constrained by law, which means that we are only able to refund a donation in certain rare, prescribed circumstances. If you believe that a donation you have made should be refunded, please contact us. If we have already transferred your payment onto the charity recommendation for the crisis you wish to support we can send you their information to talk to them directly.
