Wiwin

Wiwin is an online platform for sustainable investments, connecting private investors with projects in renewable energy, energy-efficient real estate, and sustainable startups. The company operates on a crowd-investing model, allowing individuals to invest with amounts starting as low as €250, thereby democratizing access to impactful asset classes that are often difficult for retail investors to enter.

The company was founded in 2011 as juwi Invest GmbH by Matthias Willenbacher and Fred Jung. Willenbacher, an entrepreneur in the renewable energy sector since 1996, established Wiwin to enable greater public participation in the energy transition. Following a restructuring, Willenbacher took full ownership of the company. He served as CEO for many years before stepping down in 2023 to focus on other energy transition projects. His journey began with building his first wind turbine in 1996, which evolved into co-founding juwi AG, a major developer of renewable energy plants.

Wiwin's business model involves brokering capital between investors and project owners. It offers various investment types, including debt investments with fixed interest for energy and real estate projects, and equity investments in startups. The platform is a regulated market participant, operating as a contractually bound agent under Germany's Securities Institutions Act (WpIG), ensuring regulatory compliance. All projects undergo a strict evaluation based on ecological, social, and economic criteria, which is presented to investors through the transparent 'WIWIN Impact Scoring' system. Recently, Wiwin merged with zinsbaustein.de to combine expertise and become a market leader in sustainable crowd-investing, expanding its offerings and potential for risk diversification for its investors.
