One Platform, Every Vendor: Rebuilding How Wealth Data Moves
How SEQTEK gave a major U.S. regional financial services company's wealth management systems a single, governed way to talk to each other, replacing years of one-off connections with a reusable integration layer.

The client
A major U.S. regional financial services company, whose wealth management division runs a wide set of applications and vendor systems that all need to share data, from trading platforms to custodial services to document workflows.
The problem
Before SEQTEK's involvement, every wealth integration was its own project. Connections ran between trading, custody, trust accounting, and document platforms, built through whatever mechanism each pairing called for: direct web services, scheduled batch processes, file transfers, message queues, and vendor specific interfaces. Each connection carried its own logic, its own way of handling failure, and its own approach to authentication and transport security, so how a connection was secured depended on who built it and when. There was no view of the traffic moving across them, which systems were communicating with which, what was being sent, or whether a message had landed. Tracing a single message end to end meant checking each system in turn, and failures and acknowledgments were never centralized. Cross system workflows like account onboarding, which touches e-signature, content management, and internal systems in sequence, had to be coordinated through those same one-off connections. Every new integration meant building another point to point connection from scratch.
The solution
Beginning in late 2019, SEQTEK built the client's wealth service layer, a reusable integration platform designed to sit between wealth applications and the vendor systems they depend on. The first release, delivered in 2021, proved out the architecture across three capabilities: processing trade activity from a third-party securities processing platform, handling account and customer data with that same provider, and giving an internal advisor facing application governed API access to trust accounting data in place of a direct database connection.
From there the platform kept expanding. SEQTEK moved clearing, custody, and market data providers onto the same shared messaging model, added regulatory disclosure submissions for municipal securities, and brought every connection under a consistent security model, with authentication, credential handling, and transport security applied the same way for each integration rather than decided connection by connection. Centralized logging gave support teams a single place to see where in the process a message failed and who owned the fix. The platform also took over document heavy workflows, coordinating account onboarding across e-signature, content management, and internal systems.

Each new integration took less time to build as the platform matured. Building one no longer meant building the infrastructure around it, because routing, delivery, persistence, transport protocols, and security were already defined and proven. The work was limited to what was actually unique about each vendor: its data model, its business rules, its failure modes. The same patterns and libraries carry across integrations that have nothing else in common. For example, a shared messaging library handles every connection that speaks IBM MQ, regardless of which vendor is on the other end or what the exchange is for, and the same holds for the platform's REST, SOAP, and file transfer paths. A new vendor on a familiar protocol inherits a connection layer that is already built, already secured, and already monitored.

The impact
The engagement's impact shows up in architecture and operations rather than in a single before and after number. Integrations that were once built one at a time, each with its own logic and its own approach, now run on a single reusable platform. Clearing and custody, market data, regulatory disclosure, trust accounting, and account onboarding all move through the same routing, persistence, and monitoring foundation.
Traffic that was once invisible is now observable. Support teams can see what moved between which systems and where a message stopped, and they know who owns the fix. Every connection authenticates and transports data the same way, so security is a property of the platform rather than a decision repeated with each new integration. Internal applications reach vendor data through governed interfaces instead of direct database connections.
The compounding return is in what comes next. Each integration the platform absorbs makes the following one faster to build, because the infrastructure is already there and only the vendor specific work remains. Nearly six years in, the engagement remains active, and the same foundation continues to take on new integrations as the wealth business grows.
