Overview
React Native subscription commerce app on a self-hosted Medusa v2 backend: skin-type quiz, personalised monthly box builder, pause/swap controls, Tamara BNPL, and referral programme with shareable discount links. Subscriber churn drops from 18% to 6%; referral-driven acquisitions reach 29% of new sign-ups.
The challenge
The brand was running a manual subscription via WhatsApp — customers messaged a preference list each month and staff assembled boxes by hand. This did not scale beyond 200 subscribers and churn was high because subscribers could not easily pause or swap items without a lengthy WhatsApp exchange. The brand had no way to capture referrals, which were happening organically on social media but generating no trackable revenue.
The solution
We extended Medusa v2's subscription module (community plugin) to support monthly box configurations stored per subscriber with a Gemini-backed quiz that seeds initial preferences. The React Native app exposes granular pause, swap, and quantity-adjust controls so subscribers self-manage without contacting support. Branch.io powers the referral deep-link system with dynamic discount generation per referrer tier.
Outcomes
Subscriber churn dropped from 18% to 6% within the first four months after launch
Referral-driven new sign-ups grew to 29% of all acquisitions within six months
Subscriber base scaled from 200 to 1,400 without adding any operations staff
Box personalisation quiz completion rate reached 91%, improving box satisfaction ratings

Client testimonial
“My subscribers can now swap their box from the app at 2 AM without messaging me. And my best customers send me three referrals each. The growth just happened.”
