our call
Start with Fou Analytics — 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

Fou Analytics
While creating a client-side JS beacon and telemetry dashboard with AI takes days, ad fraud detection relies on continuously updated threat models and bot databases. A self-built alternative will catch basic headless browsers but fail against residential proxy networks and stealth botnets.
you can rebuild
- Client-side JS event tracking beacon
- Basic browser detection heuristics (User-Agent parsing, headless browser flags)
- Traffic breakdown dashboards by device, referrer, and UTM parameters
- CSV and S3 automated log exports
- UTM parameter validation and link parameter tracking
what you lose
- Dr. Augustine Fou's proprietary fraud heuristics and pattern recognition algorithms
- Real-time cross-referencing against global residential proxy and datacenter IP databases
- Benchmarked invalid traffic (IVT) baselines across billions of ad impressions
- Audit-ready evidence logs formatted for ad network refund disputes
- Ongoing counter-measures against zero-day fingerprint evasion frameworks
real moats
- Proprietary dataset of invalid traffic signatures and ad fraud patterns
- Cross-merchant network effects for rapid identification of emerging botnets
- Expert reputation and audit-grade credibility in digital media supply disputes
