Referral Program

A referral program gives existing users a structured reason and mechanism to bring in new ones, usually with a reward on one or both sides. It is one of the few acquisition channels whose cost scales with success rather than with spend, and referred users typically arrive with more context about the product than a paid click delivers. It is not the same as virality: a viral loop is inherent to the product's use (an invitation is required to collaborate), while a referral program is bolted on and needs an incentive to run. The design decisions are few and consequential. Who gets rewarded — giving only to the referrer can feel extractive to the friend, while a two-sided reward gives the referrer something worth sending. What the reward is — account credit keeps value inside the product and costs less than cash, but cash converts better in categories where users do not expect to stay. And when it pays out: rewarding on signup invites gaming, while rewarding on a qualifying action (a paid month, a completed setup) aligns the program with revenue at the cost of a longer feedback loop. Two conditions determine whether it works at all. The product must already be worth recommending — a referral program applied to weak retention just accelerates churn and pays for it. And the ask must be placed where satisfaction peaks rather than in a menu nobody opens. Measure it on the incremental cost per retained customer against your other channels, and watch for self-referral and reward-farming from the first week.
