Sales visibility we had requested for three years, delivered in fourteen weeks

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

A new care pathway required patient data to move between systems in a way our current architecture did not support. The integration complexity was beyond what we could handle in-house.

E-commerce rebuild that generated positive ROI before the end of its first quarter live

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

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.

A studio that plays the games they build. It is obvious in the final product.

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

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.

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

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

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.

Data science team is actually productive now. First time in two years.

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

Our connected vehicle platform was accumulating telemetry data from a growing EV fleet with no clean way to act on it. We needed both the infrastructure and the analytics layer.
