Engineering for regulated financial services.
Audit posture is a design constraint, not a phase-five concern. We have built systems that passed SSAE 18, PCI DSS 4.0 ROC review, and NYDFS 23 NYCRR 500 examination on first pass.
Standards we hold ourselves to
What we hold ourselves to.
SOX (Sarbanes-Oxley)
For systems that materially affect financial reporting. Change control documented, segregation of duties enforced, evidence collected for SSAE 18 / SOC 1 Type II.
PCI DSS 4.0
Cardholder data scoped tightly with tokenization. Network segmentation, key management, vulnerability scanning per ASV cadence, penetration tested annually.
SOC 2 Type II
Trust Services Criteria mapped end-to-end. Our own SOC 2 audit in progress, available to customers as sub-processor evidence.
FINRA / SEC
Broker-dealer recordkeeping (17a-3, 17a-4), electronic storage media compliance, trade surveillance pipelines, suitability and KYC.
NYDFS 23 NYCRR 500
Cybersecurity program design, multi-factor authentication, encryption in transit and at rest, incident response within required windows.
Bank Secrecy Act / AML
CIP/CDD/EDD workflows, SAR generation, watchlist screening (OFAC, UN, EU consolidated), transaction monitoring.
Common engagements in this vertical.
Core banking & ledgers
Double-entry ledgers with idempotency, reconciliation against external statements, money movement orchestration.
Payment infrastructure
ACH, RTP, FedNow, wires, card. Stripe Treasury, Modern Treasury, Increase. Multi-rail routing.
KYC/AML
Identity verification (Persona, Alloy, Socure), watchlist screening, transaction monitoring with tunable rules.
Broker-dealer platforms
OMS and EMS integration, FIX engines, market data ingestion, trade reporting (CAT, OATS).
Fund administration
TroyFunds-grade LP portals, capital call workflows, NAV calculation, waterfall distribution, K-1 generation.
Treasury & corporate finance
Cash positioning, FX hedging, intercompany lending, bank API aggregation (Plaid, Codat).
What is different about doing this work.
- Idempotency keys on every money-moving endpoint. We treat retries as a first-class concern.
- Double-entry ledger primitives that audit cleanly. No deletes, ever. Reversals via offsetting entries with reason codes.
- Reconciliation jobs that fail loudly when external statements drift from ledger.
- Customer-managed encryption keys for tier-1 financial customers.
- Tabletop incident exercises annually with the customer security team.
Have a financial services build in flight?

Start a brief →They built our multi-rail payment infrastructure faster than our internal team estimate and it passed our PCI DSS 4.0 ROC review on first audit. The Stinger pen-test caught a chained RCE that unblocked our Series C.
Vertical questions, answered.
The questions buyers in this vertical ask in week one.
Are you SOC 1 ready for systems affecting financial reporting?+
Yes. We support SSAE 18 / SOC 1 Type II engagements where the system materially affects customer financial statements. Change control documentation, evidence collection, and auditor support included.
Can you work within our PCI DSS scope?+
Yes. We tokenize early to keep scope narrow. We work with Stripe, Adyen, Worldpay, and Braintree for cardholder data handling. Network segmentation, key management, and CDE controls per PCI DSS 4.0.
Do you support NYDFS 23 NYCRR 500 compliance?+
Yes. We have shipped fintech systems against the NYDFS standard. Cybersecurity program design, MFA, encryption in transit and at rest, incident response with required notification windows.
Can you build double-entry ledger primitives?+
Yes. Idempotent, append-only ledger with offsetting reversals, reconciliation jobs that fail loudly when external statements drift, and audit-grade trace through every money movement.
What about FedNow and RTP integration?+
Yes. We have shipped RTP via The Clearing House and FedNow integrations. Multi-rail routing with intelligent fallback, settlement reconciliation, and exception handling.
