Real-world examples
Case study: Airbnb’s referral growth strategy
Airbnb famously used a referral program to hack its growth. By providing incentives for users to invite friends—both inviter and invitee received travel credits—Airbnb rapidly scaled user acquisition while keeping marketing costs low. This viral loop was backed by constant experimentation, tweaking email copy, landing pages, and incentive amounts to maximize results.
