Alter GroupOU is a 100% Estonian capital based company that became active in the retail and wholesale of electrical materials in the early spring of 1997. Since 2003, the market for Marine equipment and small boats has also started due to the enthusiasm of ship owners for sailing. Initially, only electronics were sold, but products and other equipment were soon added to the product range. In December 2010, the subsidiary Alter BalticsOU was established. From then on, the main activities of the organization will take place under that name, and Alter GroupOU will continue to serve as the management company. Year after year, the organization has increased its market share not only in the sale of electrical materials but also in the field of Marine technology and has expanded to all the Baltic countries.
