grüüün is presented as a German electricity provider offering '100 % grünen Strom aus Deutschland' (100% green electricity from Germany). In its marketing, the company highlights customer-friendly pricing features such as an '18 % Rabatt' and '10 Jahren Preisgarantie' (10-year price guarantee). The positioning emphasizes sustainability and fairness, and it describes its supply as coming 'ohne Zwischenhändler' (without intermediaries) and as direct.' The brand name is also used in connection with 'Stromfürsorger' messaging (roughly, electricity caretakers/guardians).
Beyond the core tariff offering, the company also offers a consumer app called 'Mein grüüün', described as a free app that provides an overview of a grüüün electricity tariff through a 'simple, clear, and intuitive' interface. The brand maintains a presence on social media as well, including a Facebook page under the name 'grüüün – Dein Stromfürsorger'.
