You don't need an agency to make a Swiss adaptation. One copywriter is enough. No matter if the source language is English, French or Standard German. And no matter if the target language is High German, Züritüütsch, Bärndüütsch or any other Swiss dialect. Like here with TBWA\ Berlin for the spot "Show Us" from the current campaign adidas Running.
