Problem

Revenue was fully dependent on a single transaction per user.

Once a user purchased, monetization stopped completely.

This created:
• strong acquisition performance
• but heavily capped LTV
• inefficient scaling ceiling tied only to ad spend

What we did

We built a structured post-purchase monetization layer.

This included:
• designing upsell logic immediately after purchase
• testing multiple timing windows (0 min, 10 min, 24h, 72h)
• aligning offers with acquisition intent source
• segmenting users based on entry funnel
• introducing layered offers instead of single static upsell
• optimizing offer placement within user journey flow

Post-purchase was treated as a second conversion system, not an add-on.

Result

• +28–35% increase in total revenue per user (ARPU)
• 0% increase in ad spend
• same acquisition performance, significantly higher LTV
• improved payback period efficiency by ~20–30%

Key insight

Most subscription products over-invest in acquisition and under-build monetization beyond the first purchase.
