We’re on a mission to transform the way brands talk and are talked about. ​ We’re proud to be a strategic partner to some of the very best brands on the planet, helping them stay relevant, conversational, and advocated—all at the speed of social. Today’s fragmented media landscape presents myriad complex new social communications challenges. Brands are held to higher standards of humanness than ever before. That means being good listeners and being in the moment. It means being empathetic, conversational, authentic, and interesting. All this requires a fundamental communications shift—a transformation of priorities, competencies, processes, and activities.​ We’re working with some of the world’s best-known brands as a global strategic partner, building dedicated cross-functional teams across data, strategy, and activation in order to deliver Social Transformation™ to the brands. 🇩🇪 Als Agentur für Social Transformation™ begleiten wir unsere Kunden auf ihrem Weg in die Digitalisierung. Wir helfen ihnen, die Sprache von Social zu sprechen. Und zu gestalten, wie dort über sie gesprochen wird. Social Media erfindet sich jeden Tag neu. Seit über 20 Jahren sind wir strategischer Partner für einige der weltweit bekanntesten Marken, die wir tagtäglich dabei unterstützen, relevant und im Gespräch zu bleiben. Die heutige fragmentierte Medienlandschaft stellt eine Vielzahl komplexer neuer Herausforderungen an Marken. Sie sollen menschlicher sein als je zuvor: Ein guter Zuhörer und passend zum Zeitgeist. Einfühlsam, gesprächig, authentisch und immer interessant. Das erfordert einen grundlegenden Wandel in der Kommunikation – eine Transformation der Prioritäten, Kompetenzen, Prozessen und Marketingaktivitäten. Als globaler strategischer Partner bauen wir maßgeschneiderte, interdisziplinäre Teams in den Bereichen Data, Strategie und Kampagnen-Aktivierung auf, um so Social Transformation™ möglich zu machen.
