The Real Madrid and France striker has bought over 10% of the shares of the German electronics company Loewe Technology GmbH, which specializes in producing televisions, home theaters, and home speakers.
The player made the deal through his Coalition Capital investment fund.
Loewe CEO Aslan Khabiyev told Bloomberg News that the company plans to increase its annual revenue to about 300 million euros in the next two years.
"Kilian helped us a lot with the Bluetooth speaker (speaker) we developed with him. Several Mbappé's French national team teammates have also expressed their approval of this product on social networks," said Khabiev.
