About us


MainStreet Partners was created to provide any investor with a transparent and easy access to companies and funds that achieve consistent financial returns while improving people’s lives and protecting our planet. Where and how capital is deployed has a strong influence in shaping our future world. For this reason, we want our clients to know exactly where their capital is invested and what financial, social and environmental results they are achieving.


MainStreet Partners offers bespoke portfolio solutions to clients wishing to deploy capital at scale in sustainable and impact investments across asset classes and geographies, either in thematic equities and bonds or via third party funds. Applying the highest standards of financial and extra-financial due diligence, our mission and duty is to achieve positive risk-adjusted returns while delivering tangible positive social and environmental impact. MainStreet Partners has been developing its capabilities and track record of investing in sustainable companies and funds since 2008.
