Airbnb's growth team rebuilt their referral program from scratch in 2014, increasing referral bookings by 300% through systematic experimentation on incentive structure, messaging, and share mechanics.
Challenge
Airbnb had a basic referral program that was underperforming. The travel booking frequency was low (people book accommodation a few times per year), making it harder to generate referral volume compared to daily-use products. The team needed to maximize conversion on every referral touchpoint since opportunities were infrequent.
Approach
Airbnb's growth engineering team (led by Gustaf Alstromer) rebuilt the referral program with a data-driven approach. They gave the referrer $25 in travel credit when their friend completed a trip, and the friend got $25 off their first booking. Key optimizations: personalized referral pages with the sender's name and photo (which increased trust), testing every element of the referral email (subject line, CTA, image), mobile-optimized sharing flows, and integration with phone contacts for bulk invitations. They discovered that referrals from hosts converted at 4x the rate of referrals from guests, leading to a separate host referral program. The team also found that travel credits outperformed cash discounts in conversion rate.
Results
- Referral bookings increase: +300%
- Host referral conversion: 4x guest referral
- Users (2015): 60M+
- Countries with listings: 190+
