Technology Strategy & Architecture
A costed, sequenced path from legacy estate to a target the business can fund and absorb.
Technology & Data
Integration, APIs & Engineering
Connections between systems deserve the same care as the systems themselves.
Overview
Point-to-point integration builds up quietly: file transfers with no owner, undocumented connections, data feeds spliced into systems they were not designed for, and middleware only a few people understand.
Every new platform adds more unless integration is governed deliberately. Incidents become harder to diagnose, change takes longer and the estate becomes more fragile.
Capmark helps institutions replace fragile connectivity with governed, documented and monitored integration. We design the integration patterns, APIs, controls and migration path needed to connect platforms without breaking live flow.
What we do
We design standard interfaces with the security, documentation and governance needed for systems to connect in a consistent way. Every interface has an owner, a supported standard and a control path.
We match the integration pattern to the work: real time where the business acts immediately, scheduled batch where it does not. The estate becomes fast where it matters and simple where it can be.
We modernise or replace ageing middleware in stages, verifying each retired interface against live flows before switch-off. Every step has a tested way back.
We connect institutions to the networks they depend on, including payment schemes, market and settlement venues, data providers, adviser platforms and platform networks. Connections are delivered with testing, monitoring and reconciliation.
We provide the engineering discipline around integration change: standards, environments, testing, release control, monitoring and handover to the teams that will run it.
What to expect
A Principal leads from day one. The first weeks map interfaces by owner, criticality, failure mode and consuming platform, then sequence remediation so the highest-risk connections are addressed first.
New patterns are proven before legacy interfaces are switched off. Data migration, user readiness and operational controls are managed as carefully as the technology.
The engagement closes with integration standards in place, monitoring across the estate and a platform team trained to run it.
Sequenced through assessment and architecture, then delivery, migration and decommission.
01
Assess
Establish the current state, the constraints, the risks and the value at stake.
02
Define
