our call
Start with SEON — highest vibe code, weakest moat.
Accertify
Building a custom rules engine with an AI assistant takes a couple of weeks, but Accertify's moat is its vast cross-merchant transaction database and hardware fingerprint network. An isolated self-hosted application has no access to global stolen card data or collective threat intelligence. You can easily build the admin workflow, but your fraud engine will be blind to external threat actors.
you can rebuild
- Manual order review queue and analyst decision workflow UI
- Custom merchant-defined risk scoring rules engine
- Basic velocity checking and IP geolocation distance verification
- Webhook triggers to hold or release risky orders in ecommerce backends
- Basic analytics dashboards tracking approved versus flagged transactions
what you lose
- Cross-merchant global transaction and stolen card threat network
- Automated chargeback representment and dispute resolution pipelines
- Hardware-level mobile and web browser device fingerprinting SDKs
- Dedicated 24/7 enterprise threat analyst team and performance SLAs
- Pre-built processor and card brand network dispute connections
real moats
- Proprietary cross-merchant fraud signals accumulated across billions of checkout events
- Direct integrations with issuing banks and chargeback networks
- Contractual performance SLAs and financial chargeback protection options

SEON
A custom rules engine and transaction dashboard take days to code, but SEON's core value lies in its proprietary OSINT lookups and cross-merchant fraud signals. Rebuilding the software UI is simple, but aggregating social data and phone carrier intelligence across millions of profiles independently is economically unviable.
you can rebuild
- Custom drag-and-drop risk scoring rules engine
- Transaction review dashboard with manual approve/reject flags

- Real-time social profile footprinting across 35+ services
- Cross-merchant global fraud reputation network
- Telco carrier lookup for disposable phone numbers
- Evasion-resistant device fingerprinting JS agent maintenance
