What is a growth loop and why is it better than a funnel?

The short answer

A funnel pushes users in one direction and dies at the bottom; a growth loop is a self-reinforcing system where the output of one user (content, referrals, money reinvested in ads) creates the next user. Loops compound and defend against the 'every channel decays' problem. Design your growth as loops, not one-off funnels.

Growth Loops Are the New Funnels

From Reforge Blog by Brian Balfour & Reforge team ~15 min read

  • Funnels are one-directional and decay; loops feed their own output back into new-user input.
  • Every retained user should generate the next user through content, referral, or reinvested revenue.
  • Designing loops forces you to think about defensibility and compounding, not one-off campaigns.
