Retention is a discipline
The best retention teams build a system for continuous improvement
They study customer behavior, test interventions and track outcomes. ProsperStack supports that practice.
Combining customer context, experimentation tools and measurable results, we help subscription businesses improve retention with confidence.
Our values
Be customer obsessed
We start with the problems our customers face and measure our work by the value we deliver.
Take ownership
We step up, solve problems and follow through. Responsibility is not limited by role or title.
Lead with honesty
We communicate clearly, acknowledge uncertainty and tell the truth even when it’s not easy.
Be curious and humble
We ask thoughtful questions, challenge our assumptions and remain open to better ideas.
Don’t take shortcuts
We care about the quality of our thinking and our work. Durable solutions beat convenient ones.
Leadership
As subscription industry veterans, we know firsthand the challenges of growth, retention and customer churn.
