MainStreet Partners has history of innovation by pushing the boundaries of sustainable investing to new strategies and solutions without compromising its mission to combine social, environmental and financial results. The company is also involved in various industry groups, including the United Nations Principles of Responsible Investment, the MSCI Thought Leaders Council on Impact Investing and a member of the Green Bond Principles.


The Origins

The idea for MainStreet Partners was born on a biking trip across South America. Witnessing the region’s poverty and lack of development prompted Rodolfo Fracassi and Andrea Carati to think if there was a better use of their asset management experience. Once back to Europe in the summer of 2008, they founded MainStreet Partners as an investment company dedicated to impact and sustainable investments.
