Frequently Asked Questions

What does Tiff Advisory Services, Llc invest in?
TIFF Advisory Services employs a multi-manager, endowment-style investment philosophy designed to deliver diversified global equity exposure through carefully selected underlying managers and direct investments. Chief Investment Officer Jay L. Willoughby oversees the investment process, which applies the institutional investment frameworks pioneered by large university endowments to a broader foundation and nonprofit client base. Portfolio construction reflects diversified global equity allocation, seeking to capture worldwide growth opportunities while managing risk through geographic and manager diversification. The multi-manager approach leverages TIFF's scale to access institutional managers typically available only to large allocators, pooling nonprofit assets to achieve fee efficiencies and manager access.
