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

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 aftersales digital experience was built when cars had fewer connected features. It had not aged well and customer satisfaction scores in that segment confirmed it.

Analytics foundation that will support our growth for years without a rebuild

The platform has been live for six months and is handling three times the transaction volume we scoped for. That is not because we underestimated — it is because the architecture choices made during discovery were genuinely forward-thinking. Most vendors design for exactly what you tell them. This team designed for what you are likely to need. We are already scoping the next phase and there was no question about who we would use.

Project summary

Partner-level reporting required visibility into matter data that our current systems could not provide without significant manual extraction and aggregation.

Legacy-to-cloud-native in a timeline our previous vendor said was impossible

The technical quality is the obvious thing to highlight. The automated test suite is comprehensive, the deployment pipeline is solid, and the documentation is actually useful rather than written to satisfy a checklist. But the metric I keep coming back to is what has NOT happened since go-live. No 2am incident calls. No emergency patches. No post-launch retrospectives about what went wrong. For a system of this complexity, that outcome is exactly what we paid for.

Project summary

Our field service management system was six years old and every limitation had been exposed by the growth in our technician headcount and job complexity.

Reporting clarity that changed how our sales leadership plans the quarter

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

Clients were asking for real-time campaign performance data. We were delivering reports two days after the fact. The gap was becoming a retention issue.

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

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