ChurnNote vs ProsperStack
ProsperStack is a powerful cancel-flow and retention platform built to deflect cancellations with A/B-tested in-app offers, aimed at high-volume businesses with demo pricing. ChurnNote takes the opposite approach: let the cancellation happen, then learn why and win the customer back. Pick ProsperStack for in-app offer flows at scale; pick ChurnNote for reason-first recovery at a flat $12/mo.

When to Choose ProsperStack
ProsperStack fits high-volume subscription businesses that want to intercept cancellations in-app with targeted, A/B-tested offers, pauses, and downgrades. If a well-timed offer genuinely saves a meaningful share of your cancellations and you have the volume to test, ProsperStack's platform is built for it.
When to Choose ChurnNote
ChurnNote fits founders who want to understand why customers leave without building and maintaining a cancel-flow funnel. It sends a plain-text exit email after the cancellation, when answers are more honest, groups the reason, and queues a win-back when you ship the fix. Transparent flat pricing and a 5-minute setup, on Stripe or Lemon Squeezy.
Using Both Together
On Stripe, the two complement each other: ProsperStack deflects at the door, ChurnNote learns from and recovers the customers who still leave. See the ProsperStack alternative guide for the broader list.
