Our History

DIAM was founded in France in 1973 by Mr Yvon Poullain, with its core business being the injection moulding of innovative plastic products. Later becoming a leader in the POS sector as a privileged partner of many of the major international beauty brands in France and in the UK, for both Mass market and Luxury cosmetics, particularly for general tester stands and cosmetic walls.

The group then expanded its activities to include all types of market leading cutting-edge merchandising solutions for multiple beauty and luxury customers, whilst following client geographic and market expansion as partners. After further acquisitions and growth in Europe along with logistics and installation activities, the group began to expand considerably, from 2008 onwards, notably by building strong foundations in the Americas and across Asia.

The DIAM group then continued its geographical expansion over 5 continents to better serve international customers with local bases. DIAM then expanded its service offer, developing skills ranging from design to store maintenance, in order to meet the full spectrum of in store needs for brands and retailers worldwide, including their digital requirements.
