our call
Start with Signifyd — highest vibe code, weakest moat.
Signifyd
You can build the device fingerprinting script, rules engine, and Shopify order-hold webhook with AI in a weekend. What you cannot build is the bank balance required to reimburse merchants when your algorithm misclassifies a $3,000 stolen-card order.
you can rebuild
- Order hold and manual review queue automation
- Device fingerprinting and session analytics collection
- Custom risk-scoring rules engine (IP velocity, address matching, order value limits)
- Webhook routing to Shopify, Magento, and WooCommerce for order cancellation
- Basic chargeback notification webhook listeners
what you lose
- 100% financial chargeback guarantee on approved orders
- Access to Signifyd's 10,000+ merchant global identity graph
- Automated 48-hour chargeback reimbursement payouts
- Third-party enterprise liability offloading for accounting audit compliance
- Dedicated human fraud analysts for manual order re-reviews
real moats
- Balance sheet reserves capable of liquidating millions in chargeback indemnifications monthly.
- Cross-merchant device and identity graph built over a decade across 10,000+ enterprise retailers.
