Who we are

We are the only foundation linked to a global wealth manager staffed with philanthropy experts. With an approach that takes advantage of our unique network, we’re taking a leading role in driving impactful philanthropy that delivers breakthrough solutions to social and environmental issues. We know that solving these issues requires collaborative initiatives that make real impact on a large scale. So, we’re taking smart risks on evidence-based, scalable solutions with diverse partners. Together we're improving health, education and child protection systems as well as tackling environmental degradation and climate change – as this is an important path to a sustainable future.

Philanthropists choose to work with us because we take their passions personally, providing a variety of giving options and taking that journey with them. And they know that because of our expertise, innovation and network, we’re successfully finding bold solutions, giving them the powerful impact they want.


We’re proud that an ever growing number of UBS clients and employees see us as their philanthropic partner of choice. Their passion combined with our expertise has made a fundamental difference to our environment and so many children’s lives. But, we are far from satisfied and want to do even more, even better.

To that end, we will continue to work closely with our donors and frontline partners to make sure programs are delivering, as well as seeking out other innovative ideas that have the potential to bring transformative, scalable and sustainable change.
