Diffco Reviews
Have a look at these client reviews on previously delivered projects.
Matthieu Renard
Directeur Technique - Lumière Technologies SASClean migration, zero content loss, better performance — the full win we needed
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
Years of incremental development had left us with a platform that was functional but limiting. A structured rebuild was the agreed path forward.
Eoghan Fitzgerald
VP of Engineering - Shannon Tech Solutions LtdProposal matched the outcome. That alignment is rarer than vendors acknowledge.
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
Warehouse management errors were accumulating at a rate our clients could see. A proper WMS was the agreed fix — we needed a development partner who had built one before.
Laura Jiménez
Head of Digital Products - Catalonia Digital SLDelivered on scope, on budget, and with zero critical bugs at go-live
We went with a smaller team than we had originally planned for. I had concerns about whether the capacity would be sufficient given our timeline. Those concerns were unfounded. The team was focused, communication was constant, and the quality at each milestone review was consistent throughout. Smaller does not mean slower when the people are the right ones and this engagement proved that.
Project summary
A new product line required machine tooling integrations we had no experience with internally. We needed engineering expertise that had done this before.
Fatima Al-Suwaidi
Head of Digital Strategy - Gulf FinTech HoldingsVR training module preferred by 89% of trainees over the classroom alternative
We handed them an aggressive deadline, a complex scope, and a client-side team that was stretched and not always available when they needed us. They handled that gracefully. They were precise about what they needed and when they needed it. Where they could proceed independently they did. The delivery landed on time in spite of the constraints we added. I regard that as strong evidence of genuine professional maturity — not just capability.
Project summary
Our compliance team had flagged gaps that needed fixing before our next regulatory review. The work was too specialist for our internal team to absorb without dropping the product roadmap entirely.
Wei Xin Chua
Product Director - Lionhead Digital Pte LtdArchitecture review that saved us from a vendor decision we would have regretted
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
Our conversion funnel showed exactly where we were losing customers. The platform was the problem and we knew it — we just needed a team experienced enough to fix it properly.
