"Since 2007, the Rockefeller Foundation has been committed to the growth and development of the impact investing sector as a way to address social and environmental challenges and accelerate benefits to poor and vulnerable people. B Lab has been a critical partner in this work and with the creation of GIIRS has laid some of the foundational infrastructure needed to expand the sector and address the world's social challenges."
- Dr. Judith Rodin, President - The Rockefeller Foundation

"Sustainability - economic, social and environmental - is increasingly driving investor decision-making across industries. Sustainability is not a fad, but rather an essential ingredient for business success in the 21st century. One of the payoffs for GIIRS-rated companies that integrate sustainability into strategy is the opportunity to attract investments for growth. As a leading global sustainability assurance, tax and consulting provider, Deloitte is pleased to support the evolution of the GIIRS social impact tool."
- Jack Russi, National Managing Partner, Corporate Development - Deloitte

"Entrepreneurs that are addressing intractable problems like inadequate shelter, lack of healthcare, and climate change need access to private capital. USAID is a strong supporter of B Lab's work on GIIRS because of its potential to help entrepreneurs attract investors who want to address these persistent development challenges around the world."
- Rob Schneider, Senior Alliance Advisor - USAID
