Test early fraud signals for merchant retention
Fraud controls can be available long before their purpose becomes usable to a new merchant.
More visibility may help, but visibility without a decision model can become another source of uncertainty.
“I know the risk tools are there, but I’m not confident which signal should change what.”

What pulls against what
- retention correlation vs. causal understanding
- feature discovery vs. decision quality
- signal transparency vs. false certainty
- fast experimentation vs. responsible risk interpretation
What is at stake
A retention signal points to an opportunity, but not yet to a product decision. The work is to discover what helps merchants make better risk choices
Why Stripe
At Stripe, this can matter because early confidence in payment controls may shape how merchants grow on the platform.
