Partners & Supporters

The Ethos Foundation was created by and for Swiss pension funds in 1997, and now counts over 250 pension funds as members. With the pioneering aim of enabling pensions to invest responsibly, Ethos is an ideal partner for our first-of-its-kind ranking of asset managers.

The collaboration with the Zurich University of Applied Sciences (ZHAW) Center for Global Competitiveness is a critical component of the III’s research focus. CGC researchers solve practical business problems using scientific knowledge & research techniques.

Initial research support for the ranking was provided by an Innovation cheque from Innosuisse. Innosuisse is the Swiss Innovation Agency focused on promoting science-based innovation in the interest of the economy and society.
