Hamburg – In 2014, real estate professionals Simon Brunke, Björn Maronde, Julian Oertzen and Tim Bütecke founded Exporo AG, which brings together project developers and investors via its real estate financing platform. Some are looking for financing alternatives to bank loans and others for high-yield investment alternatives. Crowd investing platforms thus bring investors and borrowers together for mutual benefit. Building contractors can use the mezzanine capital provided by investors to partially finance their projects. The mezzanine capital enables project companies to release parts of their traditional equity from bank financing and to use the released capital flexibly for real estate projects. This flexibility is so important to the companies that they offer investors and investors attractive interest rates of five to seven percent.
