Fintech Infrastructure

The backend architectural components, including ledgers, payment rails, and compliance tools, that enable the building and scaling of financial applications.

Key Details

Core layers include Banking-as-a-Service (BaaS), payment processing, ledger systems, reconciliation engines, compliance/KYC, and analytics
Unlike consumer fintech apps, infrastructure companies provide the backend plumbing that other fintechs build on — analogous to AWS for cloud computing
Key infrastructure decisions include build vs buy for each layer, single-vendor vs best-of-breed strategy, and on-premise vs cloud deployment
Modern fintech infrastructure is API-first, enabling programmatic access to banking, payments, and financial operations capabilities
Infrastructure reliability requirements are stringent — downtime directly impacts money movement, making high availability and disaster recovery critical
