Stiftung Constanter is a private charitable foundation founded by Brenninkmeijer family entrepreneurs and based in Switzerland.

Constanter supports charitable projects that promote respect for human dignity and social justice. It works in the areas of education, society, care and faith. Further, it encourages the development of a sustainable business environment and the empowerment of people locally to help those in need in a sustainable way.

As is the case with the family’s other charitable entities, Constanter is supported in developing and executing its grant-giving programmes by the Porticus organisation. Constanter also works with other family-related philanthropic organisations, such as Laudes Foundation.
