Cashback: Turning a Retention Challenge into Measurable Growth
I led the product and systems analysis for a cashback initiative designed to improve customer retention, helping translate a business objective into an automated crypto payout flow. After launch, customer churn decreased by 17%, repeat purchase rate increased by 67%, and two-month revenue per cardholder grew by 44%.

The opportunity
Cashback was approached as a lever to improve retention and encourage customers to use their cards more frequently.
The challenge was not simply to introduce a reward in the user interface. The product needed a reliable way to calculate and deliver rewards while integrating with the existing financial infrastructure and preserving the integrity of money flows.
The solution had to connect the customer-facing cashback experience with the underlying transaction and payout processes.
My contribution
1. Product definition and retention objectives
I worked on translating the retention objective into a concrete product solution. The focus was on creating a cashback mechanism that could encourage repeat usage while remaining compatible with the existing card and financial systems.
I helped define the required behavior and align the product experience with the operational and financial requirements behind it.
2. Money-flow design and systems analysis
I designed the money-flow model and carried out the systems analysis needed to support cashback payouts.
A key part of the solution was integrating with Safe so that crypto payouts could be executed automatically following the required signing process.
My work included:
- —Translating product requirements into system behavior and implementation requirements.
- —Designing the money flow behind cashback payouts.
- —Analyzing system interactions and payout scenarios.
- —Aligning the customer-facing experience with the underlying financial operations.
- —Working through the details needed to make the solution operational rather than merely a front-end feature.
This connected the retention mechanism to the actual movement of funds and the systems responsible for executing payouts.
3. Cross-functional delivery and post-launch assessment
I led the project through its delivery process, working across the product and technical aspects of the implementation.
After launch, I assessed the available business metrics to understand how the initiative performed against its retention and engagement objectives.
This made it possible to evaluate the project in terms of observed customer and revenue outcomes, rather than treating successful delivery as the only measure of success.
Results
−17%
Reduction in customer churn.
+67%
Increase in repeat purchase rate (RPR).
+44%
Increase in two-month revenue per cardholder.
These results show that the initiative was associated with improvements across retention, repeat usage, and cardholder revenue.
The metrics represent observed post-launch results; they should not be interpreted as proof that cashback alone caused every change, without further analysis of other contributing factors.
What this demonstrates
- —Product thinking: translated a retention objective into a concrete customer-facing product capability.
- —End-to-end ownership: led the project across product definition, systems analysis, delivery, and post-launch assessment.
- —Technical depth: designed money flows and worked through the integration required for automated crypto payouts.
- —Financial systems understanding: connected a rewards mechanism to payout execution and underlying financial operations.
- —Measurable impact: assessed the initiative against churn, repeat purchase rate, and revenue per cardholder.
My contribution focused on product and systems design, money-flow architecture, project delivery, and evaluating post-launch performance.
