Grantmakers, Investors, and Advisors

From our earliest days, GLG has supported foundations and intermediaries on the front lines of philanthropic innovation. And as the private sector embraces ESG and impact investing more broadly, we’re working with many GLG clients who are building impact initiatives. Our platform helps all of our clients navigate the evolving landscape of social impact – where the need for expertise has never been greater.

Grantmakers turn to GLG Social Impact for insights on program design, implementation, and measurement, as well as for support for their grantees.

Sample engagements include:

  • Deep dives into business-process outsourcing in the Middle East
  • Consults on American urban redevelopment processes
  • Analysis of the Ebola crisis’ effects on economic, social, and health systems in West African countries
Impact Investors

We help impact investors understand and maximize return and minimize risk with market scans, diligence calls, access to deal specialists, and board placements.

Sample engagements include:

  • Diligence on off-grid energy infrastructure in South America
  • Best practices for structuring impact deals to preserve liquidity and emphasize impact
  • Place-based impact audits to inform social-return metrics
Consulting and Advisory Firms

Nonprofit consultancies and advisory firms utilize GLG’s custom offerings to understand complex social issues and validate or dismiss hypotheses.

Sample engagements include:

  • Consults on waste recycling in India
  • Expertise for an advisory meeting on adaptive strategy, rapid innovation, and lean principles
  • Landscape analysis of K-12 formative and interim assessments
