Informing a Top Social Sector Advisory Firm’s Client Deliverables and Recommendations

We’ve worked closely with The Bridgespan Group (TBG), a leading advisor to nonprofits and NGOs, philanthropists, and investors since 2013. 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 deliverables and recommendations to TBG clients.

Example projects include:

  • Talking to utility providers, medical professionals, and environmental scientists about the diverse impacts of nuclear waste discharge from power plants.
  • Learning from oral health experts to identify high-impact opportunities to create systems change.
  • Speaking with futurists to survey major emerging threats to human safety, size the risk of these threats, and understand opportunities to address them.
