Course Overview

What this course is designed to develop

Most referral programs are a forgotten link in a footer that nobody clicks. This course teaches the operator's craft behind the ones that work: the viral-loop math that decides whether a program compounds or fizzles, the incentive economics tied to your margin and customer lifetime value, the timing and friction details that change share rates by multiples, and the fraud and disclosure traps that quietly drain budgets. You will leave able to model your own loop, design an incentive your unit economics can sustain, choose a real platform, and read the metrics that tell you whether referral is becoming a reliable acquisition engine.
