Quick answer
Seypro builds regulated financial infrastructure — trading and order-management connectivity, settlement workflows, KYC/KYB/AML onboarding, and the reconciliation infrastructure that surfaces mismatches before they hit a client statement. We built and run the platform behind MERJ Exchange, a regulated national securities exchange with five connected public, investor, issuer, and administrative platform surfaces.
Case study · In production
The engagement spans public markets, investor and issuer workflows, administration, market data, and compliance tooling. Seypro has delivered incrementally alongside the MERJ team within a regulated operating environment.
Engineering teardowns
A regulated system is not one that never has problems. It is one where problems are caught, diagnosed, and closed before a client, a regulator, or a board finds them first. These are incident teardowns from live production work.
What we build
Not a capabilities menu — the parts a regulator, auditor, or board actually inspects, built as one platform.
Order management systems, execution connectivity, real-time market data, and broker/venue integration. Built on FIX protocol. Tested under production load.
Real-time settlement, custodial accounting, and reconciliation logic that surfaces mismatches before they reach a client statement. Every transaction is traceable.
End-to-end onboarding flows with identity verification, AML screening, sanctions checks, and audit trails on every action — built to the controls a regulator inspects.
Message queues with failover, idempotent processing, encrypted data exchange, and the monitoring that proves uptime. ISO 27001-aligned controls on production systems.
When something goes wrong in a regulated system, every hour of ambiguity has a cost. We diagnose at the source-code level — not by restarting services and hoping.
Automated reconciliation jobs that diff what the platform says against what the counterparty says — and surface the delta before a human has to find it manually.
MERJ Exchange · production record
Zero critical incidents across 18+ months in production — trading, settlement, KYC/AML, and reconciliation running concurrently on a national securities exchange serving 135 jurisdictions.
