What ProsperStack does
ProsperStack builds cancel flows with embedded surveys, personalized offers, and A/B testing. When a customer clicks "cancel," ProsperStack shows them a flow designed to save them — and tests different offers to optimize save rates. It's focused on the moment of cancellation with a scientific approach to retention offers.
What RetentionCheck does differently
RetentionCheck works upstream of the cancel flow. Instead of optimizing what happens when someone clicks cancel, it analyzes feedback from any source to understand why they're considering cancellation in the first place. It's the diagnostic step that tells you whether you need better pricing, missing features, or improved onboarding — not just a better cancel flow.
When to use ProsperStack
Use ProsperStack when you have high enough volume to A/B test cancel flows meaningfully (typically 100+ cancellations/month) and you've already addressed root-cause churn drivers. It shines at optimizing the last mile of retention.
When to use RetentionCheck
Use RetentionCheck when you're not sure what's driving churn, or when you want to fix the root causes rather than intercept at the door. Most SaaS founders benefit more from understanding why customers leave than from A/B testing what to offer them as they go.
The verdict
ProsperStack is a scalpel for the cancel flow. RetentionCheck is the diagnostic that tells you where to cut. If you can only pick one, start with understanding the problem (RetentionCheck) — then decide if you need cancel flow optimization at all. Many founders discover that fixing the root cause reduces churn more than any cancel flow ever could.
