Efficient information management is of high relevance for the success of young and entrepreneurial service companies. These ventures face a high level of uncertainty due to their lack of knowledge about market development, customer acceptance and customer behaviour. In consequence, one of the main marketing challenges is to deal with and thus lower uncertainties perceived by service entrepreneurs and their customers. Following the information economics approach, we argue that efficient information management can be theoretically framed as an essential ingredient to entrepreneurial marketing. A qualitative empirical study is used to verify the findings and to gain deeper insights into the marketing information management of young and entrepreneurial service ventures.
