Went live on time and under budget. Our CFO framed the project charter.

We went with a smaller team than we had originally planned for. I had concerns about whether the capacity would be sufficient given our timeline. Those concerns were unfounded. The team was focused, communication was constant, and the quality at each milestone review was consistent throughout. Smaller does not mean slower when the people are the right ones and this engagement proved that.

Project summary

Our internal team was committed to maintenance and could not absorb a new build of this complexity. An external partner was the only way to hit the timeline.

Positive ROAS in the first full campaign cycle. We did not expect it quite that quickly.

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

We were losing deals to competitors whose platforms offered capabilities ours simply could not match. A targeted technology investment was the agreed response.

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

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.

Project summary

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

A DevOps engagement that changed both the tooling and the culture

We went with a smaller team than we had originally planned for. I had concerns about whether the capacity would be sufficient given our timeline. Those concerns were unfounded. The team was focused, communication was constant, and the quality at each milestone review was consistent throughout. Smaller does not mean slower when the people are the right ones and this engagement proved that.

The kind of technical partnership you hope for but rarely find on the first try

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

Open banking changes required us to rebuild our API layer properly — compliant by design, not patched together. We needed specialist engineers, not generalists.
