How Soundstripe retained 500 customers and recovered $20K in 90 days

Churn volume was high, but customer context was limited

Soundstripe was losing thousands of customers each month without capturing meaningful feedback or detailed metrics about why they canceled. Its multiple pricing packages added another layer of complexity: a single retention offer would not be relevant to every subscriber.

The team needed a more precise way to manage the cancellation moment — one that could personalize retention by customer cohort, measure performance and turn cancellation data into insight for the broader business.

Targeted experimentation improved retention performance

With ProsperStack, Soundstripe segmented customers by subscription plan and created multiple sets of coupons for each cohort. Customers automatically received incentives aligned with their plan, creating a more relevant retention experience at the moment of cancellation.

Soundstripe then used automated A/B testing to compare offer language and discounts, identify the strongest performers and continuously improve its retention strategy.

In 90 days, the program retained 500 customers and recovered $20K in revenue while delivering a 5x return on investment.

Cancellation insight informed product strategy

The value extended beyond individual saves. ProsperStack’s reporting, analytics and export tools gave Soundstripe a clearer view of cancellation trends and retention performance.

Soundstripe now automatically shares those insights with its product team, turning cancellation feedback into ongoing input for roadmap decisions. The result is a more coordinated approach to retention — connecting personalized intervention at cancellation with improvements across the customer lifecycle.
