Duo Consulting Reviews

Have a look at these client reviews on previously delivered projects.

Consulting engagement that paid for itself in avoided rework within six months

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

An enterprise client contract required a level of reporting transparency our existing platform could not provide. Building it was a condition of the renewal.

Custom workflows that match our sales motion exactly. No workarounds needed.

Our stakeholder group was unusually broad — board sponsors, operational users, compliance leads, and an IT team with strong opinions. I have watched vendors handle that kind of environment badly. This team adjusted how they communicated depending on who they were talking to, managed expectations honestly when things shifted, and delivered something that each group considers a success. Getting everyone to agree on that outcome was not straightforward and they deserve credit for making it happen.

Project summary

A licensing agreement required us to demonstrate GxP-compliant data management to a partner's satisfaction. Our existing infrastructure failed that assessment.

Infrastructure-as-code that our team uses as a reference example internally

Honestly, I came into this engagement with some scepticism. We had a bad experience with a vendor twelve months earlier and I wanted to see evidence of competence, not just hear about it. The discovery documentation was the first signal. The sprint delivery consistency was the second. By go-live I had stopped being sceptical and started planning how to expand the engagement. The production system has been stable from day one and our internal team loves working with the codebase they left us.

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 team knew blockchain AND our industry — combination we struggled to find elsewhere

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 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.

Platform engineering work that finally let product teams move independently

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.
