Self-reinforcing systems that compound user acquisition over time
Growth loops replace the traditional funnel model with circular, self-reinforcing systems where output becomes input. Unlike funnels that require constant top-of-funnel investment, loops compound over time. Examples include content loops (users create content that attracts new users), viral loops (users invite friends), and paid loops (revenue funds more acquisition). Understanding growth loops is the modern framework for sustainable growth, used by companies like Pinterest, Slack, and Notion to achieve massive scale with efficient economics.
