IT partner that understands our business, not just our ticket queue

The technical quality is the obvious thing to highlight. The automated test suite is comprehensive, the deployment pipeline is solid, and the documentation is actually useful rather than written to satisfy a checklist. But the metric I keep coming back to is what has NOT happened since go-live. No 2am incident calls. No emergency patches. No post-launch retrospectives about what went wrong. For a system of this complexity, that outcome is exactly what we paid for.

Project summary

Years of incremental development had left us with a platform that was functional but limiting. A structured rebuild was the agreed path forward.

Ad spend efficiency improved 40% without reducing reach. The targeting work was the difference.

I have been through several technology implementations in my career. The pattern I am used to is: detailed proposal, optimistic timeline, scope creep, overrun, excuses at the end. This engagement broke that pattern at every stage. The timeline was realistic from the start. Changes were managed through process. The final delivery matched what was agreed. Simple, but uncommon.

Project summary

The business case had been approved but the internal resource to execute it had not materialised. External delivery was the pragmatic solution.

Every milestone hit. Every commitment met. No excuses, just delivery.

Three months post-launch our key metrics are all moving in the right direction — user adoption ahead of target, support volume down, time-on-task reduced for our core workflows. The product team has started planning features that were never viable on the previous platform. That is the real proof of the investment: it opened up possibilities rather than just replacing what was there before.

Project summary

International expansion required multi-currency, multi-language, and multi-warehouse capability our current platform could not support without a rewrite.

Delivered what the proposal described. More rare than it should be.

Project summary

OTA update orchestration for our software-defined vehicles needed to be bulletproof. The liability implications of getting it wrong were significant enough to justify specialist development.

Our marketing team can now update the site without filing a ticket. Life-changing.

The technical quality is the obvious thing to highlight. The automated test suite is comprehensive, the deployment pipeline is solid, and the documentation is actually useful rather than written to satisfy a checklist. But the metric I keep coming back to is what has NOT happened since go-live. No 2am incident calls. No emergency patches. No post-launch retrospectives about what went wrong. For a system of this complexity, that outcome is exactly what we paid for.

Project summary

B2B customer churn was concentrated in accounts that rated our self-service portal poorly. A redesign was necessary before the next wave of contract renewals.
