Workflow automation that freed our editorial team from tasks they had been doing manually

We handed them an aggressive deadline, a complex scope, and a client-side team that was stretched and not always available when they needed us. They handled that gracefully. They were precise about what they needed and when they needed it. Where they could proceed independently they did. The delivery landed on time in spite of the constraints we added. I regard that as strong evidence of genuine professional maturity — not just capability.

Project summary

The project had a board-level visibility date. We needed a partner who would treat the deadline as their own.

Infrastructure spend down by a third. Same performance, better architecture.

The knowledge transfer at the end of the project was notably good. Too many vendors see handover as a tick-box exercise. This team ran structured sessions, produced documentation our internal team actually references, and spent real time making sure we understood the architecture decisions well enough to maintain and extend the system independently. Six months later we are doing exactly that without needing to go back to them for every question.

Project summary

Streaming quality issues were generating subscriber churn at a rate that made the technical investment case straightforward to approve.

Complex project, zero drama. That is how you know the project management is real.

Project summary

Grid modernisation funding required us to demonstrate demand-response capability. The ML models existed on paper — we needed an engineering partner to build and deploy them.

Marketing stopped being a cost conversation and became a revenue conversation

We received proposals from six vendors. Four of them quoted us prices that bore no relationship to the actual scope. This team came back with something realistic and then delivered against it exactly. I have worked on enough technology projects to know that the gap between what is proposed and what is delivered is where trust gets destroyed. There was no gap here. What was promised is what we got, and the ongoing relationship we have built from this is something we intend to continue.

Project summary

An enterprise client contract required a level of reporting transparency our existing platform could not provide. Building it was a condition of the renewal.
