Case Study: Yellow Card achieves 1M users and 30% reduction in CPI with AppsFlyer

How Yellow Card hit 1M users with multi-touch attribution and deep-linking

Yellow Card, a fintech startup using crypto rails to provide fee-free transfers across Africa, switched to a mobile-first model in late 2021 and faced rapid scaling challenges: it could only monitor installs (not in‑app events), had siloed paid media data, and aimed to grow from 400K users to 1M and boost monthly active users. To solve this, Yellow Card selected AppsFlyer as its mobile measurement partner (using AppsFlyer’s measurement suite and OneLink deep‑linking) to get real‑time attribution and better leverage owned and paid channels.

By integrating AppsFlyer’s measurement suite, OneLink deep‑linking and ROI360, Yellow Card gained a single source of truth for ad spend, routed users directly to product flows (Yellow Pay, KYC) and optimized its media mix. With AppsFlyer’s solutions, Yellow Card scaled from ~200K users in December 2021 to 1M by March 2022, delivered a 74% quarter‑over‑quarter rise in app installs and cut cost‑per‑install by 30%, while improving conversion quality and marketing efficiency.
