our call
Start with Trustfull — highest vibe code, weakest moat.
Trustfull
AI can write a full-featured risk rule engine and signal aggregation service in a afternoon. However, you cannot easily replicate Trustfull's underlying access to direct mobile carrier networks, HLR lookups, and global breach databases without paying high third-party data fees.
you can rebuild
- Custom risk scoring rule builder and threshold evaluation engine.
- Basic IP risk lookup (VPN/Tor/Proxy detection via public databases).
- Email syntactical analysis, disposable domain checks, and MX record verification.
- Redis-based velocity tracking for identity fields (e.g., requests per phone number per hour).
- Audit logging and structured API response formatting.
what you lose
- Direct access to real-time mobile network operator (HLR/SS7) data without setting up separate vendor contracts.
- Cross-merchant global reputation data on fraudulent phone numbers and email addresses.
- Unified billing and SLA management for multi-signal data sources.
- Pre-built compliance workflows for European privacy standards (GDPR) regarding identity lookups.
real moats
- Proprietary integrations and wholesale volume rates with international HLR/telecom data aggregators.
- Aggregated historical data on phone/email reputation built across millions of evaluation requests.
- Low-latency global API infrastructure serving unified risk responses under 100ms.

Vesta
While building a device fingerprint collector and rule-based risk dashboard takes days, Vesta's core offering is zero-liability financial guarantees and cross-merchant network signals. AI agents cannot generate financial underwriting balance sheets or billions of historical fraud data points.
you can rebuild
- Basic rule-based risk scoring engine (velocity, country blocklists)
- Client-side device fingerprinting collector script
- Order approval and rejection queue for manual review
- IP geolocation, proxy, and VPN detection API integration
- Threshold-based 3D Secure dynamic triggers
what you lose
- 100% zero-liability chargeback reimbursement guarantee
- Cross-merchant consortium dataset tracking fraudsters across thousands of stores
- Machine learning models trained on billions of historical card transactions
- Automated chargeback evidence submission and dispute handling
- Dedicated fraud analyst teams and custom enterprise risk models

- Financial balance sheet supporting chargeback indemnification
- Global cross-merchant graph dataset linking identities, devices, and cards
- Proprietary ML models trained on real-world dispute outcomes
