About the store
The company sells travel eSIMs that give travellers mobile data abroad without a physical SIM card.
The program
A Dutch travel eSIM provider runs a double-sided referral program in BLOOP, with the first referral orders arriving in February 2025. The friend gets €3 off and the customer who refers them gets €2 off.
Results
In the last six full months (April to September 2026), referral revenue was 195% higher than in the six months before.
48% of the friends who received the €3 reward used it on an order.
12% of referred friends came back and placed at least one more order after their first referral purchase.
The €3 friend reward is worth about 23% of an average referral order, so the store pays a small, predictable amount for each new customer.
