Transforming the impact of human generosity

We started Supergenerous because charitable donors around the world are owed billions of dollars in tax rebates, which haven’t been claimed because the process to do so is time-consuming. If everyone claimed and re-donated, that money could be used by charities to make a huge dent in the challenges the world faces.

Supergenerous is a digital service that automates the process of claiming back a charitable tax rebate. It requires just a couple of minutes from most donors – allowing them to effortlessly re- donate up to 33% of their past donations.

Supergenerous not only facilitates these re-donations, we also aim to generate powerful new insight into what motivates donors’ generosity, and how charitable organisations can inspire the greatest generosity from their supporters.

We believe that human generosity is the solution to the world’s greatest challenges and are passionate about creating a world where it’s effortless for charities and donors to capture the full value of that generosity.

We’re a small team of passionate Kiwis building a social enterprise that we hope will make a big difference to charitable giving all over the world.
