This course is focused on ways and techniques used by enterprises in order to identify and fulfill the needs and expectations of their clients/consumers and to make profit for themselves at the same time, especially with limited financial resources in the early stages of enterprise development (start-up phase) or in small businesses. The basic marketing principles as well as categories of conventional marketing will be contrasted to the requirements of non-conventional marketing, marketing that is focused on what is practical, i.e. pragmatically and financially limited marketing (guerilla type of marketing).
