  • VIP tier thresholds and customer level tracking
  • Points redemption for auto-generated discount codes
  • Customer-facing loyalty balance and widget display
  • Referral link tracking and reward issuance

  • No-code drag-and-drop rule engine for non-technical teams
  • Automated receipt parsing and fraud verification
  • Dedicated loyalty strategist support and enterprise SLAs
  • Machine-learning point value and campaign performance analytics

real moats
