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.

The UBS Optimus Foundation Network consists of the UBS Optimus Foundation in Switzerland, its branch in Hong Kong and the representative office in China, its sister organizations UBS Optimus Foundation Europe, UBS Optimus Foundation UK, UBS Optimus Foundation India, UBS Optimus Foundation Singapore and UBS Optimus Foundation Australia, as well as a donation platform in the United States.
