Digitisation is among the macro-trends that significantly influence the business world in the twenty-first century. Firms striving to succeed in this environment must develop new strategic approaches. The accelerating development of information technology (IT) drives digitisation. Therefore, IT and business strategies must be integrated. In this context, the information systems literature promotes the concept of digital business strategies (DBSs), reflecting a fusion between IT and business strategies. However, knowledge of the types and characteristics of such DBSs is currently scarce. Therefore, we developed a conceptually and empirically grounded typology of DBS based on the well-known business strategy classification by Miles and Snow (1978). Using a dataset comprising 192 firms worldwide, we conducted a cluster analysis, identified basic types of DBS, and evaluated their effects on firm performance. Moreover, we identified four types of DBS: non-digital reactor, analyser, digital opportunist, and digital producer. The study contributes to a better understanding of new business strategy concepts in the digitisation context.
