What is Critical Mass for a product

“Critical mass for a product is the point at which it becomes self-sustaining. Adoption of the product (and retention of existing users) reaches a point where the product becomes profitable and continues to be profitable over time.”

“It is difficult to determine exactly when that point will be reached or where exactly that point is – however, we can take action to develop KPIs which enable us to see if we are progressing towards critical mass. Some business models are highly dependent on reaching critical mass early and these should be approached with caution if you do not have a large marketing budget to drive critical mass.”
