The Two-Sided Referral Loop
A referral motion that measures real users, not vanity invites.
Your users recruit users
A referral loop where both sides understand the value. The existing user has a reason to share, and the invited user lands in a clear, useful flow.

EvidenceHow Dropbox grew: a two-sided in-product referral where both sides got real value (Sean Ellis, Hacking Growth). The mechanic still works; that era's viral multiplier is not promised.
What happens next
We build it, document it, and hand it over.
Your loop now runs on its own rails: every invite, signup, activation, and reward lands in a funnel your owner reads in one view, and rewards only fire when a referred user actually activates. When you want to push volume, you change the invite copy or the moment it appears, and the dashboard tells you within a cohort whether it recruited real users or just clicks.
