Wiwin logo
WiwinSB Score: 308

The basic idea behind the investments offered by us on their platform is that you, as an investor, can invest your money in sustainable projects together with a large number of other investors, eg through crowdinvesting. Because when many investors join forces through WIWIN, they can already make large investments possible with small individual amounts and thus help us to advance the energy transition. Thus, for example, a wind turbine can be acquired together with other donors, which is otherwise reserved for very wealthy individual investors or companies. Their platform makes it easy for you to quickly and easily select the desired investments and to manage them after a successful subscription online.
