Over time, a small company founded in Prague, the capital of the Czech Republic, has become an international company with almost a hundred employees and collaborators, with activities in more than 60 countries. whole world. We focus on operating nearly two hundred websites and applications that provide users with an overview of discount events and favorable offers from sellers from all possible categories. Our website and app content includes information about several thousand retailers and their locations, products and brochures. Although the core of our activity is the operation and development of websites and applications for end users, our rich database of stores and their brochures or catalogs also serve as a source of content for our business partners, including multinational media houses. They use our detailed data to create interesting content for their own readers. In the B2B segment, we are also developing a new product, ecPaper, designed for the creation of interactive digital catalogs, which saves costs for our customers – large and small commercial or manufacturing companies – and significantly increases digital sales potential.
