National securities exchange
Built and run in production — multi-tenant, audit-grade, with zero critical incidents in over a year of operation.
Regulated fintech
Systems thatclear real money.
Capital-markets engineering — trading connectivity, settlement, identity, and compliance built to clear regulatory review.
Trading platforms, settlement engines, KYC/AML, and the messaging infrastructure behind regulated finance. We've built a national securities exchange — from zero, to production, to audit.
The receipts
A national exchange. Built, not bought.
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.
Seypro engineers regulated financial systems — trading and order-management connectivity, real-time settlement, KYC/KYB/AML onboarding, and the message-queue infrastructure that moves transactions reliably. We built and run the platform behind MERJ Exchange, a national securities exchange: a multi-tenant, audit-grade system with zero critical incidents in over a year of production.
Regulated financial systems engineering — the platforms that move orders, settle trades, verify identities, and survive an audit. We build trading and order-management connectivity, real-time settlement and custody logic, KYC / KYB / AML onboarding and screening, and the message-queue infrastructure that keeps transactions reliable under load. This is capital-markets engineering: transaction-grade integrity, multi-tenant isolation, and audit trails on every action.
Coverage spans trading & connectivity (order management, execution and market-data connectivity, broker and venue integration), settlement & custody (real-time settlement, reconciliation, custodial accounting, collateral and reporting), identity & compliance (KYC/KYB onboarding, AML screening, sanctions checks, regulatory reporting, conformity documentation), and reliable infrastructure (message queues with failover, idempotent processing, encrypted data exchange, and the monitoring that proves uptime). Built to be inspected — every transaction traceable, every control documented.
Built and operated in production: the platform behind MERJ Exchange, a national securities exchange — engineered from zero to a live, multi-tenant, regulator-facing system with zero critical incidents since launch. Fintech engagements pair tightly with security & compliance and payment integrations — because in regulated finance, those aren't separate projects.
Flagship
Most firms integrate a vendor. We built the exchange.
Order management, settlement, custody, identity, and the messaging backbone — engineered in-house and run in production. When the regulator asks how it works, we can answer at the line-of-code level.
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
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.
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 reconciliation jobs that keep onboarding compliant over time.
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.

Yes. We built and run the platform behind MERJ Exchange, a national securities exchange — a multi-tenant, audit-grade system covering order management, settlement, custody, and identity, with zero critical incidents in over a year of production. It is engineered in-house, not assembled from a vendor product.
Yes. We build KYC/KYB onboarding, AML and sanctions screening, audit trails on every action, and the regulatory and conformity reporting a financial regulator inspects. Compliance is engineered into the platform rather than bolted on afterwards.
Yes. We build order-management systems, execution and market-data connectivity to brokers and venues using standards-based messaging, and real-time settlement and custody logic with reconciliation. The infrastructure underneath uses message queues with failover and idempotent processing so transactions don't drop, double, or stall.
