Quick answer
What does Seypro build in regulated fintech? Seypro engineers regulated financial systems — trading and order-management connectivity, settlement workflows, KYC/KYB/AML onboarding, and the message-queue infrastructure that keeps transactions from dropping, doubling, or stalling. We built and run the platform behind MERJ Exchange, a national securities exchange: a multi-tenant, audit-grade system with five connected platform surfaces delivered through an ongoing production engagement.
Regulated fintech engineering covers the hardest parts of financial software: order management and settlement systems, KYC/KYB/AML onboarding, and the messaging infrastructure that keeps transactions from dropping, doubling, or stalling under regulatory scrutiny. We built and operate MERJ Exchange, a national securities exchange running 18+ months in production with zero critical incidents. Engagements typically combine trading connectivity and settlement, compliance and identity infrastructure, and payment integration.

A national exchange. Built, not bought.
National securities exchange
Built and run in production — multi-tenant, audit-grade, with zero critical incidents in 18+ months of operation.
Real-time settlement
Order management and settlement engineered for transaction-grade integrity, not eventual consistency.
Regulator-cleared
Identity, audit trails, and reporting built to satisfy the controls a financial regulator actually inspects.
What we build
Trade. Settle. Comply.
The three hard problems of regulated finance — moving orders, moving money, and proving both to a regulator. Engineered as one platform.
Trading & settlement
Order management, execution and market-data connectivity, real-time settlement, custody, and reconciliation — engineered for transaction-grade integrity.
- Order management systems
- Execution & market-data connectivity
- Real-time settlement & custody
- Reconciliation & reporting
- Broker / venue integration
Identity & compliance
KYC/KYB onboarding, AML and sanctions screening, audit trails, and regulatory reporting — the compliance backbone, built in rather than bolted on.
- KYC / KYB onboarding flows
- AML & sanctions screening
- Audit trails on every action
- Regulatory & conformity reporting
- Reconciliation & oversight tooling
Fintech engagements pair tightly with security & compliance and payment integrations — because in regulated finance, those aren't separate projects.
Capabilities
The infrastructure under a regulated platform.
Connectivity, settlement, identity, and integrity — the parts a regulator inspects and a vendor can't sell you off the shelf.
Regulated fintech engineering covers the hardest parts of financial software: order management and settlement systems, KYC/KYB/AML onboarding, and the messaging infrastructure that keeps transactions from dropping, doubling, or stalling under regulatory scrutiny. These systems don't get second chances — a settlement engine that loses a transaction or an identity platform that passes a sanctioned entity creates regulatory liability, not just a bug ticket.
We built and operate MERJ Exchange, a national securities exchange — multi-tenant, audit-grade infrastructure running 18+ months in production with zero critical incidents. The platform spans trading and order management, real-time settlement and custody, KYC/KYB onboarding, AML and sanctions screening, reconciliation, and the message-queue backbone that ties them together. Every component was engineered to the standard a financial regulator inspects.
Fintech engagements typically combine trading connectivity and settlement, compliance and identity infrastructure, and payment integration. For institutions operating across jurisdictions, security and penetration testing runs alongside every production build — in regulated finance, these aren't separate projects.
Trading connectivity
Order, execution, and market-data connectivity to brokers and venues — standards-based messaging engineered for correctness.
Real-time settlement
Settlement and custody logic with transaction-grade integrity, reconciliation, and collateral handling.
KYC / KYB / AML
Identity verification, AML and sanctions screening, and ongoing compliance checks that keep the client register current and clean.
Reliable messaging
Message queues and streaming with failover and idempotent processing — transactions don’t drop, double, or stall.
Audit & reporting
Versioned audit trails and regulatory reporting — the evidence a regulator, auditor, or board demands.
Secure data exchange
Encrypted file and message exchange (PGP, secure transport) for bank, broker, and counterparty integration.
