Financial products operate under the strictest regulatory requirements and the highest user trust expectations. Whether you're building a payments platform, neobank, or investment tool, the architecture decisions you make on day one will determine your compliance burden for years.
Building in Fintech without the right technical guidance means navigating serious pitfalls with high stakes.
Navigating PCI-DSS, PSD2, and regional banking regulations without in-house legal expertise
Building audit trails and transaction reconciliation that satisfy regulators
Selecting payment processors and banking-as-a-service partners that match your geography
Designing fraud detection that minimises false positives without blocking legitimate users
CTO Assistant generates a complete technical specification tuned to the realities of Fintech — not a generic template.
Every fintech spec includes a dedicated Compliance dimension covering PCI-DSS scope reduction, KYC/AML obligations, and data residency requirements for your target markets.
Understand the trade-offs between Stripe, Adyen, and regional processors — including fee structures and feature gaps — before signing any contracts.
Get recommendations for encryption at rest and in transit, secret management, penetration testing cadence, and SIEM tooling.
Spec out open banking (Plaid, Tink, TrueLayer) connectivity, webhooks, and idempotency patterns that prevent double-charges.
Products built in this space that set the standard for what's possible.
