our call
Start with Fou Analytics — highest vibe code, weakest moat.
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
open source escape hatches
- BotD Apache-2.0
- Matomo GPL-3.0
- Plausible Analytics AGPL-3.0
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.
open source escape hatches
- FraudLabs / open rules engines (Drools) Apache-2.0
- Feedzai alternatives — River BSD-3
- MaxMind minFraud open clients Apache-2.0
