our call

Start with Billie — highest vibe code, weakest moat.

Billie

Billie is not a software tool; it is a financial institution and risk-taking engine that advances working capital and assumes default risk for B2B buyers across Europe. Prompting a checkout UI is trivial, but an LLM cannot provide balance sheet capital, perform credit scoring via Creditreform, or legally collect defaulted B2B debt.

you can rebuild

  • Checkout UI payment modal for selecting invoice payment terms
  • Basic merchant dashboard for tracking transaction statuses
  • Custom invoice PDF generation and emailing trigger
  • Order status webhooks for ecommerce platforms
  • Manual net-terms account approval interface

what you lose

  • 100% default protection (non-recourse risk transfer to Billie)
  • Real-time B2B credit scoring and instant buyer credit limit decisions
  • Upfront cash payout to the merchant regardless of buyer payment delays
  • Automated cross-border European debt collection and legal processing
  • BaFin and EU financial regulatory framework compliance

real moats

  • Balance sheet liquidity to fund 30-120 day credit windows at scale
  • Proprietary B2B credit risk models built on historical European company dataset
  • Regulatory licensing and banking partner integrations for invoice factoring

Checkout.com

Checkout.com is a licensed electronic money institution and direct card acquirer. While you can use AI to build a custom checkout UI or smart payment router over existing gateways, replacing Checkout.com's underlying infrastructure requires direct card scheme access, HSM vaults, and global regulatory compliance.

you can rebuild

  • Custom checkout UI components and form fields
  • Transaction status dashboards and reporting views
  • Basic webhook processing and event logging
  • Rule-based payment gateway routing logic
  • Simple rule-based fraud screening pre-checks

what you lose

  • Direct Visa/Mastercard scheme acquiring and settlement
  • PCI DSS Level 1 certified tokenization and HSM vaulting
  • Access to 150+ regional payment methods (e.g. iDEAL, Pix, Sofort)
  • Native 3D Secure 2 (3DS2) protocol and exemption engine
  • Multi-jurisdiction electronic money and payment institution licenses

real moats

  • Payment institution licenses and regulatory compliance across global jurisdictions
  • Direct card scheme memberships and bank clearing house connections
  • PCI DSS Level 1 security infrastructure and HSM key management
