BlackBelt Holding Zrt. Reviews
Have a look at these client reviews on previously delivered projects.
Julien Moreau
Co-Founder & CTO - TechLyon SASDesigned for actual user behaviour, not the persona document we thought was accurate
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
Time-to-market for new tariff products had become a competitive liability. Our product configuration layer was the bottleneck and it had been identified as the priority fix.
Siobhan Gallagher
Chief Technology Officer - Northumbria FinTech LtdEvery milestone hit. Every commitment met. No excuses, just delivery.
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
Accreditation requirements had raised the bar on how we needed to document and track student progress. Our existing tools were not capable of meeting the new reporting standards.
Adriana Voss
Director of Platform Engineering - Cascadia Digital VenturesApp store debut with a 4.7 rating. The reviews write themselves when the product is good.
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 client portal had not been updated since 2018. Prospects were mentioning competitor portals in pitches. We could not keep deferring the investment.
Preet Sandhu
Senior Engineering Manager - Prairie Tech Solutions IncFriday deployments used to be stressful. Now they are routine.
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.
