    Every referral program has a K-factor: average invites sent per user × conversion rate of those invites. Below 0.3, you're paying acquisition costs through the back door. Above 0.7, you're compounding.

    The math is brutal but clarifying. It tells you exactly where to invest — better invite UX, stronger reward, or a different audience.
