WIWIN is a German financial services company that operates as a digital platform for sustainable financial products. Founded by energy transition pioneer Matthias Willenbacher, it channels capital to project owners in renewable energy, real estate, and startups with sustainable business models. The platform enables private investors to participate financially in the sustainable transformation, typically starting from 250 euros, and acts as an intermediary rather than providing investment advice. The three main shareholders — Matthias Willenbacher, Sontowski & Partner Group, and Dr. Peters Group — support WIWIN with expertise in renewables, real estate, and tangible assets, while the firm functions as a contractually bound intermediary under German law (WpIG) and operates on behalf of the Concedus GmbH. The company is based in Germany at 14 Schneebergerhof Gerbach, Rhineland-Palatinate 67813, and has mediated capital of more than 360 million euros to over 220 projects.
