# Winback

> Winback (Winback HQ) wins back cancelled, expired-trial and billing-failed subscribers for RevenueCat and Stripe apps, and charges only when someone comes back.

Winback reads a subscription app's RevenueCat or Stripe events (cancellations, expired trials that never converted, billing issues), writes each lost subscriber one personal message based on what they actually did in the app, attaches an offer only within limits the founder sets, and reports who came back. Founders can plan a win-back campaign in the browser at https://winbackhq.com/planner/ from a RevenueCat or Stripe export (files never leave the browser). Pricing during early access: no monthly fee, 15% of revenue from subscribers Winback brings back, for six months. Winback is built by AGUNA Wellness Ltd (RC 9590421, Nigeria), which runs it on its own subscription app, AGUNA.
