our call
Start with Sardine — highest vibe code, weakest moat.
Riskified
Riskified is not a software company; it is a financial guarantor that uses AI to price risk. Building the transaction classification model takes days, but taking on the financial liability of millions in chargebacks requires a balance sheet, not a script.
you can rebuild
- Browser fingerprinting and device velocity tracking script.
- Rule-based fraud evaluation engine (e.g. shipping/billing country mismatch).
- Shopify fulfillment hold integration based on risk thresholds.
- Order review dashboard for manual fraud analysts.
- Automated representment documentation compiler for payment processors.
what you lose
- 100% financial reimbursement for fraudulent chargebacks approved by the engine.
- Global merchant network graph covering tens of millions of cross-store identities.
- Direct relationships with major acquiring banks for payment routing exemptions.
- Turnkey liability transfer—store operations teams don't handle fraud disputes.
- Zero-friction dynamic checkout escalation protocols (Adaptive Checkout).
real moats
- Balance sheet capitalization to underwrite chargeback losses at enterprise scale.
- Cross-merchant global behavioral network data accumulated over a decade.
- Contractual risk-transfer agreement with enterprise merchants shift balance sheet liability.

Sardine
Sardine relies on low-level device telemetry (typing cadence, accelerometer data, canvas fingerprinting) cross-referenced against millions of global transactions. An AI-built alternative lacks the cross-merchant data consortium required to catch sophisticated fraud rings and stolen credentials.
you can rebuild
- Custom static risk rules (e.g., flag orders over $500 with mismatched billing/shipping)
- Basic IP geolocation and proxy/VPN detection checks
- Dashboard UI for manual order review and approval workflows
- Basic velocity checking (e.g., card attempts per IP per hour)
- Email domain validation and disposable email domain checks
what you lose
- Global cross-merchant device fingerprinting and risk identity graph
- Behavioral biometrics tracking (hesitation, typing cadence, paste detection, mouse movement patterns)
- Real-time bank account and crypto-onramp risk intelligence
- Automated machine learning models trained on millions of fraud outcomes
- Zero-day fraud attack pattern detection across peer networks
real moats
- Cross-merchant shared identity and fraud intelligence graph
- Patented behavioral biometric feature extraction algorithms
- Integrated AML, sanctions screening, and chargeback guarantee coverage

Questions people ask
Which is easier to rebuild with AI, Riskified or Sardine?
Sardine. It scores 3/10 on vibe code with a moat of 8/10, so an AI-assisted MVP takes about 2 weeks and a full replacement about Never — requires proprietary global device graph data and ML models trained on billions of cross-merchant sessions..
Which one costs less, Riskified or Sardine?
Sardine at $1,500/mo/mo for a typical mid-market store. The gap between the two is about $12,000/mo a year.
What do I lose if I replace Riskified?
100% financial reimbursement for fraudulent chargebacks approved by the engine. Global merchant network graph covering tens of millions of cross-store identities. Direct relationships with major acquiring banks for payment routing exemptions.
