AbstractThe platform-based companies have taken over the modern digital economy but a thorough empirical investigation is needed to unveil the mechanisms ensuring their sustainable growth. The research is focused on understanding the viral loop, together with the network effects that form its close bond, the challenges that it brings along, and the implications of these for the company’s survival and prosperity in the future. The key finding discloses that success of a platform does not depend on the number of users but on their engagement quality. Growth that is sustainable is caused by a "spark" of immediate user value, an intentionally devised moment of success that triggers the network effect. The study points out to a significant trade-off between the aggressive user acquisition and the deep user engagement, and it also recognizes that viral loops are limited by natural saturation points. Hence, there is a need for a transition in the metrics used from deceptive "vanity metrics" (e.g., total downloads) to enlightening "vitality metrics" (e.g., user retention, interaction density) that correctly reflect the health of a platform. The researchers with this paper agree that the sustainable growth of platforms is not something that can happen once and for all but rather a continuous effect of the so-called "flywheel". Platform strategists will have to change their focus to product- and community-centric models that put the user experience above the short-term acquisition tactics which are, in fact, the very opposite of what academia views. The latter will have to alter its thinking and regard the network effects as a hidden potential that will only be released through intentional and user-focused design.
