Designed for actual user behaviour, not the persona document we thought was accurate

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

Post-pandemic buyer behaviour had shifted heavily to online. Our digital infrastructure had not kept pace with that shift and it was showing in our inquiry volumes.

First AR project we have shipped where the frame rate held across every device we tested

Looking back, what strikes me most is how little drama there was. Real technology projects have problems. This one had them too — but every problem was flagged before it became a crisis, every scope change was handled through a proper process, and every risk was managed rather than buried. Our project manager said it was the smoothest vendor engagement he had been involved in. Given how complex the technical requirements were, I think that reflects genuine delivery maturity.

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.

Implementation with the documentation and change management it deserved

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

Multi-touch attribution across our full media mix was the most consistently requested capability by every client in our book. We could not deliver it without rebuilding the data foundation.

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

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 audience data sat in eight different tools with no shared identity. Personalisation was impossible without first solving that foundation problem.

Technically strong, commercially fair, and genuinely good to work with

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 previous vendor had left us with a codebase that worked but was nearly impossible to extend. We needed to fix that without stopping delivery to the business.
