our call
Start with Subuno — 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.

Subuno
Subuno's underlying tech is an IF/THEN rules engine connected to third-party identity/risk lookup services. Rebuilding the UI and rule execution in Node.js is trivial, but maintaining contracts, schema mappings, and API keys for a dozen external fraud vendors is not worth the overhead for most merchants.
you can rebuild
- Custom IF/THEN rule engine for flagging high-risk orders
- Manual order review queue with approve/reject actions
- Email alerts and webhook triggers for flagged transactions
- Basic IP geolocation and address verification (AVS) checks
- Custom merchant-defined whitelists and blacklists
what you lose
- Pre-integrated access to 15+ external fraud data providers
- Unified billing and unified payload normalization across third-party identity APIs
- Cross-merchant shared bad-actor detection network
- Zero-maintenance e-commerce store platform plugins
- Turnkey automated order status updating in connected store platforms
real moats
- Aggregated integration maintenance across a broad mesh of specialized risk APIs
- Cross-merchant shared blacklists and fraud signal history
- Low subscription fee relative to managing multi-vendor API overhead directly
