Customer Referral Program

Classic referral-program viral loop

The Dropbox 'invite a friend for 500MB' playbook is still the strongest viral-loop pattern in SaaS. Adaptable to any consumer-prosumer product.

The playbook

  1. 1
    Make the reward proportional to product value

    Dropbox gave storage (the thing customers wanted most). Don't give a $10 discount; give product.

  2. 2
    Make sharing one-tap, both directions

    Inviter gets reward + invitee gets bonus. Both sides need to want to play.

  3. 3
    Show the share UI repeatedly without nagging

    Onboarding + after milestone moments + dashboard. Not every screen.

  4. 4
    A/B test reward sizes obsessively

    Dropbox tested 500MB vs 1GB vs 250MB. The 'right size' depends on perceived value of each unit.
