Celadon Reviews
Have a look at these client reviews on previously delivered projects.
Gustavo Ferreira
VP of Technology - Amazônia Digital LtdaSales visibility we had requested for three years, delivered in fourteen weeks
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 licensing agreement required us to demonstrate GxP-compliant data management to a partner's satisfaction. Our existing infrastructure failed that assessment.
Matthieu Renard
Directeur Technique - Lumière Technologies SASThe outcome we needed, on the timeline we needed it, by people we would use again
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
We were losing deals to competitors whose platforms offered capabilities ours simply could not match. A targeted technology investment was the agreed response.
Julien Moreau
Co-Founder & CTO - TechLyon SASPlatform engineering work that finally let product teams move independently
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
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.
Melissa Ortega
VP of Product - Brightline EdTech IncFirst QA engagement where the team found bugs before the client did. Consistently.
Three months post-launch our key metrics are all moving in the right direction — user adoption ahead of target, support volume down, time-on-task reduced for our core workflows. The product team has started planning features that were never viable on the previous platform. That is the real proof of the investment: it opened up possibilities rather than just replacing what was there before.
Project summary
A merger left us maintaining two incompatible student systems. Data was duplicated, staff were frustrated, and the consolidation had been deferred twice. It could not wait any longer.
Flynn Buchanan
GM of Technology - Pacific Rim Commerce GroupTechnology roadmap the CFO could actually approve — finally
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
The project had a board-level visibility date. We needed a partner who would treat the deadline as their own.
