Tokenisation from whitepaper to mainnet without a single major incident

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

Expanding to a second clinic location exposed how much of our current platform assumed a single-site model. We needed an architectural overhaul before scaling further.

The outcome we needed, on the timeline we needed it, by people we would use again

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

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

Custom software that actually solved the problem — not just the stated requirements

Three months post-launch our key metrics are all moving in the right direction — user adoption ahead of target, support volume down, time-on-task reduced for our core workflows. The product team has started planning features that were never viable on the previous platform. That is the real proof of the investment: it opened up possibilities rather than just replacing what was there before.

Project summary

As a technology company ourselves we hold our vendors to the same standard our clients hold us to. Finding a partner who could meet that bar without being hand-held through the process was the challenge.

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

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

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.
