What our clients are saying…

  • Codorníu Raventos - International Brand Manager Europe & Asia

    “About Nielsen data: It is once again very positive for us because while the category fell by 11.6% in value, and the cava category decreased by 5.6%, we are once again the green dot in the data, growing vs. the previous year's and increase of market share. These results are clearly related to the MKT campaigns during April and July. So, once again, thank you very much for your wonderful support. We are achieving great things in the UK thanks to these impactful marketing campaigns.”
