Distribution
One very small change: we made the referral program look better and added a tiered reward system — invite five people get the free year, invite 20 get a lifetime sub, a special prize at 50. This led to 80% improvement in how many people sent the referral to at least one person.

Tiered Referral Rewards UI Delivered 80% More People Sending at Least One Invite

Opal improved its referral program with a tiered reward structure and visualized progress in a well-designed UI. The result was an 80% improvement in single-invite sends. No new incentive budget was required — the change was purely structural, transforming an opaque invite screen into a gamified goal with clear progression milestones that motivated users to take that first share action.
