Factorial Complexity Reviews
Have a look at these client reviews on previously delivered projects.
Gustavo Ferreira
VP of Technology - Amazônia Digital LtdaProactive monitoring prevented an issue that would have cost us a trading day
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 audience data sat in eight different tools with no shared identity. Personalisation was impossible without first solving that foundation problem.
Aarav Mehta
Chief Data Officer - Zenith FinServ LtdCompliance programme delivered on time and approved without remediation
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
The EV transition had created dealer network management requirements our existing DMS was not designed for. A targeted rebuild was the only path forward that timeline would allow.
Julien Moreau
Co-Founder & CTO - TechLyon SASOutsourced IT that simultaneously improved the service level and the cost line
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
Our product thinking was strong. Our execution capacity in this specific domain was limited. We needed deep expertise, not a generalist willing to learn on our time.
Laura Jiménez
Head of Digital Products - Catalonia Digital SLTest automation our developers adopted as a tool rather than a compliance burden
The technical quality is the obvious thing to highlight. The automated test suite is comprehensive, the deployment pipeline is solid, and the documentation is actually useful rather than written to satisfy a checklist. But the metric I keep coming back to is what has NOT happened since go-live. No 2am incident calls. No emergency patches. No post-launch retrospectives about what went wrong. For a system of this complexity, that outcome is exactly what we paid for.
Project summary
Telehealth demand had turned a pilot into a core service line faster than our technology could keep up. We needed a compliant, reliable platform and we needed it quickly.
Clémentine Aubert
Head of Digital Products - Arc-en-Ciel Digital SASClean migration, zero content loss, better performance — the full win we needed
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
Broker portal satisfaction scores had fallen for two consecutive years. Specific feedback pointed to the same workflow frustrations. We needed a redesign, not a patch.
