What is Viral Cycle Time?

Short answer: The average time it takes for one user to invite another and for that invitee to convert and send their own invitations.

Definition

The average time it takes for one user to invite another and for that invitee to convert and send their own invitations.

Why it matters for growth

Shorter viral cycle time compounds growth faster even at the same K-factor, since more cycles complete within any given time window.

Example

A messaging app with a two-day viral cycle time will grow far faster than one with the same K-factor but a two-week cycle time.
