The problem

Small marketplaces lose 6-9% of GMV to chargebacks and account-takeover. Off-the-shelf tools are tuned for enterprise risk teams, not lean ops.

Challenges
  • - Streaming evaluation under 80ms p95.
  • - Calibrating signals for low-volume merchants.
  • - Explaining model decisions to non-technical reviewers.
