Philanthropies and Foundations

GLG partners with some of the world’s most important foundations and nonprofits.

Foundations turn to GLG for insights to support grantmaking and to evaluate mission-aligned investments. Nonprofit advisors work with us to inform landscape assessments, in-depth research, and client work. Through these partnerships, we help design and implement new philanthropic interventions and advance creative financing solutions for social change.


We’re proud to partner with organizations at the center of the global philanthropic ecosystem.

Providing Expertise to a Top Social Sector Advisory Firm

Since 2013, GLG Social Impact has worked closely with The Bridgespan Group (TBG), a leading advisor to nonprofits and NGOs, philanthropists, and investors. TBG consultants use GLG to engage experts across sectors and geographies through phone consultations, focus groups, and in-person and virtual events, gaining insights to inform their recommendations to TBG clients and other deliverables.


Example projects include:

Talking to utility providers, medical professionals, and environmental scientists about the impact of nuclear waste discharge from power plants.

In addition, the foundation’s program-related investments (PRI) team has worked with GLG to evaluate mission-aligned investments – from thesis development to diligence to post-investment support.
