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

history 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.

On July 29th 2022, Allfunds Group signed an agreement to acquire a 65% stake in MainStreet Partners, with the acquisition being successfully closed by Allfunds at the beginning of 2023. At the same time, Banca Generali, a long-standing client of MainStreet and Allfunds, has acquired a 10% stake in the company, providing a strong and complementary shareholding structure. Our management team, led by Rodolfo Fracassi, continues to drive the growth of MainStreet and maintains a 25% shareholding in the company.

MainStreet Partners maintains its brand, the same leadership team that has been managing the company over the past years together with its ESG research specialists and remains operationally independent. MainStreet Partners also maintains the same business model and services, whilst benefitting from the scale and resources offered by the partnership with Allfunds Group.
