A viral loop is a self-perpetuating cycle in which users of a product or service organically drive new @User Acquisition (UA) through their own actions, often by sharing, inviting, or otherwise exposing others to the offering. This concept is fundamental to many digital platforms and applications, where growth is fueled not just by traditional marketing, but by users themselves becoming a key channel for distribution. Viral loops typically leverage @Network Effects, in which the value of the product increases as more people use it. The effectiveness of a viral loop can be measured by the viral coefficient, which calculates how many additional users each new user brings in. Elements such as incentives, social sharing, and seamless onboarding are common features that reinforce this cycle.
