Wiwin develops sustainable rating system for crowdinvesting projects

The Mainz-based company wants to enable investors to make more informed investment decisions.

The Mainz-based investment platform Wiwin has developed a rating system to help investors clearly identify how sustainable a potential investment is. Wiwin was supported in this by the scientist Julia Hartmann. She is a professor of management and sustainability at the EBS University of Business and Law and has been a member of the Wiwin advisory board since 2021.

The "Wiwin Impact Scoring" is made up of three different project categories: Renewable Energy, Sustainable Real Estate and Green Startups. Six assessment dimensions are defined for each of these categories, for example, in the case of renewable energies, project type, contribution to the energy transition, involvement, company purpose and product. "The six scores of the evaluation dimensions then result in an aggregated total score for each project, which is presented using a scale from 0 to 100," explains Carlotta Claußen, Business Development & Impact Manager at Wiwin.

"Unfortunately, most investment products labeled as green are nothing more than deceptive packages," says Wiwin founder Matthias Willenbacher. "In the crowdinvesting sector, we are now taking an important step and ensuring greater transparency." His company, founded in 2016, is thus taking a pioneering role.
