HashEx Reviews
Have a look at these client reviews on previously delivered projects.
Pieter van den Berg
Senior Product Manager - Polder SaaS BVCheckout completion rate improved from day one of production. Not week three — day one.
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
Years of incremental development had left us with a platform that was functional but limiting. A structured rebuild was the agreed path forward.
Tom Harding
Founder - Meridian SaaS LtdDelivered what the proposal described. More rare than it should be.
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.

Beatriz Cavalcanti
Chief Digital Officer - Cerrado Tech SADelivered what the proposal described. More rare than it should be.
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
B2B customer churn was concentrated in accounts that rated our self-service portal poorly. A redesign was necessary before the next wave of contract renewals.
Bilal Chaudhry
Co-Founder & CTO - Indus Software HouseDesign system that finally brought visual consistency to a product with four years of debt
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
Peak season traffic would regularly expose platform instability. Every year we patched. Finally we decided to fix it properly rather than worry about it again twelve months later.
Clémentine Aubert
Head of Digital Products - Arc-en-Ciel Digital SASImmersive build that landed exactly where the brief pointed — and then kept going
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
A new commercial property division required tooling that was fundamentally different from our residential platform. Extending the existing system was not viable.
