(1) Context: There is large evidence in the literature that digitalisation improves the market performance of enterprises and, as a consequence, it helps the growth of their businesses. Through digital platforms companies connect with people, improve awareness of their brands, influence consumer's attitudes, collect feedback from them, improve products and services on sale and, at last, increase their incomes. (2) Method: We carried out a context analysis on the current status of research related to digital platforms in order to identify their distinguishing "dimensions" and then, come up with a sound definition for the IT-platform concept. (3) Results: In light of the study of the literature, it was possible: (a) to set the IT components necessary to build a digital platform suitable to support companies in implementing the Informative Marketing strategy; (b) to detail a process that implements such a marketing strategy by means of a adopted actual digital platform.
