Chief executives from top international companies, independent practitioners and even Irish government figures were among the 50-odd guests who attended «rOCkUCO,» a special event organized by Ocuco in Dublin in July. The 2-day event included a trip to the Guinness Storehouse, a museum that was the first Guinness brewery in the city, and a heavily attended concert by U2. The Irish company claims to be the second-largest supplier of optical retail software in the world and the largest one in Europe. With offices in the U.K., the U.S., France, Italy, Spain and Australia, Ocuco aims to become the largest supplier worldwide, offering support to customers in the language of their choice.
