"RETAIL(UN)COVERED was far more to us than just a stage at EuroShop – it was an opportunity to create a space for exchange, new ideas and an open-minded outlook on the future of retail. In SIGMA AV, we had a partner by our side who not only made our idea technically feasible, but also supported it with great commitment and a deep understanding of our requirements. This professional yet straightforward collaboration played a key role in turning our vision into a vibrant space for dialogue. For that, we’d like to say: thank you very much, SIGMA!"
