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

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

A new product line required underwriting logic that our legacy system could not support without a rewrite of the rules engine. The workarounds had accumulated to the point of being unmanageable.

Core Web Vitals are green across the board. Our SEO team sent a thank-you note.

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

Years of incremental development had left us with a platform that was functional but limiting. A structured rebuild was the agreed path forward.

Decentralised architecture that our compliance team could actually sign off on

Technology roadmap the CFO could actually approve — finally

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 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.

The team understood mobile-first before we finished explaining the brief

What set this team apart in practice was their engineering judgment — specifically, their willingness to tell us when our requirements were wrong and explain what to do instead. Not every vendor does that. The consultative element elevated the final output well beyond what our original brief described. We ended up with something better than what we had asked for, which is not a sentence I expected to be writing in a review.

Project summary

Grid modernisation funding required us to demonstrate demand-response capability. The ML models existed on paper — we needed an engineering partner to build and deploy them.
