ISO 27001 certification achieved on the first attempt. The preparation was that thorough.

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

A regulatory change required us to rearchitect how we stored and processed customer call data. The timeline was set externally, not by our roadmap preferences.

Proposal matched the outcome. That alignment is rarer than vendors acknowledge.

What I appreciated most was that they were honest when things were not going to plan. There was one point mid-project where a dependency was going to affect our timeline and they told us three weeks before it would have become critical. That gave us time to adjust. Vendors who manage upward proactively are rare. This one did it consistently throughout the engagement.

Project summary

A failed engagement the previous year had made us more rigorous about vendor selection. We took the time to find a partner we actually trusted before we committed.

Proactive monitoring prevented an issue that would have cost us a trading day

We have worked with a few agencies over the years and the comparison is honestly not close. What stood out from the start was that they spent serious time understanding the problem before they proposed anything. Once development started, every sprint review was clean — no hidden surprises, no slipped milestones. The production system has been running for four months without a single critical issue. Our internal developers reviewed the codebase at handover and were genuinely complimentary about the quality. That does not happen often.

Smooth launch, great reviews, no embarrassing bug reports from users in the first month

The part of this project I had been most worried about was the integration work. Our system landscape is complex, some of the upstream APIs were barely documented, and one of our third-party vendors was notoriously slow to respond. This team documented what the upstream vendors could not, built resilience into the architecture where third-party reliability was uncertain, and delivered integrations that have worked exactly as specified since day one. I genuinely could not have asked for more.

Project summary

A regulatory deadline required us to modernise how we reported on network performance. The data engineering needed to support it was not something our internal team could absorb without help.

A vendor that earned a place on our preferred supplier list through delivery, not sales

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

Our product thinking was strong. Our execution capacity in this specific domain was limited. We needed deep expertise, not a generalist willing to learn on our time.
