Local Presence

Our location within Guatemala allows us to witness the realities of the country firsthand. We personally visit each partner nonprofit to ensure open communication, comprehension, and honesty. This allows us to more effectively assess programming, verify funding use, and monitor and evaluate projects.

We carefully evaluate our partner nonprofits using a unique methodology developed specifically for Guatemala, based on 5 pillars:

We have a large portfolio of vetted Guatemalan nonprofits working across various theme areas. We thoroughly assess all of our partner nonprofits, which are smaller in size and truly need assistance.

Our Fees

Our location in Guatemala means reduced overhead which translates into lower fees. Unlike other intermediaries, we do not take a percentage of donations; instead, we give the full donation amount to the nonprofit and charge a separate, reasonable fee for our consultancy and data services.
