Gameplay mechanics implemented with the polish and feel our design doc demanded

Project summary: Production downtime was costing us significantly each quarter and our existing monitoring infrastructure had no predictive capability whatsoever.

Project governance was one of the things that impressed me most. We had a dedicated project manager who ran tight fortnightly sprints with clear acceptance criteria, a shared backlog that gave us full visibility at all times, and a change request process that was fair and transparent. Nothing slipped through the cracks, no bill shock at the end, and the final delivery matched the original scope document almost perfectly. In my experience that kind of discipline is genuinely uncommon.

PROS

Engineering quality that our internal team can maintain without calling the vendor, thorough documentation, proactive risk identification throughout the project

CONS

The volume of quality documentation they produced was genuinely impressive but also meant our team needed dedicated time to review it properly — a minor process point, not a complaint

Questions & Answers

Please describe your company, your role, and the industry you operate in.

Lumiere Digital SAS operates across the Manufacturing sector with offices in Paris, France. In my capacity as Directeur Technique I oversee both the strategic and operational technology agenda. We are a growth-stage business that needed a development partner capable of scaling with us rather than constraining us.

What specific problem or business challenge led you to hire this company?

Growth into new markets had exposed serious limitations in our platform. What had worked for our original user base in Paris, France was not going to scale internationally, and the Game Development requirements for those new markets were meaningfully different. We needed a partner who had solved that kind of problem before.

What services did the company provide for your project?

The full Game Development lifecycle from discovery through to production deployment and hypercare support. This included requirements workshops, solution architecture, sprint-based development, QA and automated testing, deployment to our cloud environment, and a structured handover with documentation. They also provided a brief post-launch period of dedicated support which was genuinely useful.

Why did you choose this company over other providers you considered?

Price was a factor but not the deciding one. They were mid-range in our evaluation. What tipped it was the combination of their technical depth in Game Development, the seniority of the team they proposed to assign to our account, and the clarity of their project governance model. We had been burned by an agency that overpromised before and we needed to see evidence of process maturity.

How clearly did the company understand your requirements and business goals?

Extremely well. They asked detailed questions, challenged vague requirements until they were specific, and proposed sensible defaults for decisions we had not yet made rather than just leaving them open. By the time development started there was no ambiguity in the backlog, which is a rare starting position.

How was your overall experience with their communication and project management?

Outstanding. I have worked with agencies that communicate beautifully during the sales process and go quiet during delivery. This was the opposite — structured, consistent, and genuinely informative throughout. Problems were surfaced early with proposed solutions rather than just problem statements, which made the inevitable mid-project decisions much easier to make.

Did the company deliver the project on time and within your expected budget?

On time and within the agreed budget. They had given us a range estimate at the start, which I had been sceptical of, and they landed within the lower half of that range. Their estimation accuracy came from having broken the work down in genuine detail during discovery rather than giving a rough number and hoping. It showed in every sprint.

What tangible results or business impact have you seen since the project was completed?

The ROI case we presented to our board assumed a payback period of eighteen months. Based on current trajectory we will hit that in under a year. The efficiency gains in our Manufacturing operations have been more significant than the model projected, partly because the quality of the data coming out of the new system is enabling decisions we could not make before.

What did you like most about working with this company?

The continuity of the team. The engineers who scoped the work were the engineers who built it. That sounds like it should be standard practice but in my experience it often is not. The institutional knowledge that comes from that continuity pays dividends at every stage, particularly when you are dealing with a complex Manufacturing domain where context takes time to build.

Would you recommend this company to others, and would you work with them again?

Yes. The referral I would give comes with context: they are not the cheapest option and they are not the fastest to schedule. If you are optimising purely on price or looking for someone to start tomorrow, there are other choices. If you want the work done properly and a partner you can trust with a complex, high-stakes Game Development engagement, this team is the answer.

CRM build that finally brought our sales and customer success teams onto one platform

Project summary: The project had both a hard delivery date tied to a board commitment and a scope that our previous agency had told us was not achievable. We needed someone to prove otherwise.

I have worked with development agencies on four continents over the past fifteen years and this team sits comfortably in the top tier. What separated them was not just technical skill, which was genuinely impressive, but their instinct for asking the right business questions before reaching for a technical answer. The project ran to schedule, the architecture is clean and well-documented, and the handover was thorough. Six months after go-live we have not raised a single critical support ticket. That speaks for itself.

PROS

Architectural decisions that will serve us for years rather than just solving the immediate problem, knowledge transfer that left our team genuinely capable, no scope creep at all

CONS

Premium pricing compared to some of the alternatives we evaluated, but the quality of the output and the absence of rework costs made the investment straightforward to justify

Questions & Answers

Please describe your company, your role, and the industry you operate in.

As CTO at Horizonte Digital Ltda, I manage a cross-functional technology team serving our Gaming & Gambling clients from São Paulo, Brazil. We are a commercially focused organisation and every technology decision we make is evaluated against a clear business case. We needed a partner who understood that context, not just the technical brief.

What specific problem or business challenge led you to hire this company?

Growth into new markets had exposed serious limitations in our platform. What had worked for our original user base in São Paulo, Brazil was not going to scale internationally, and the CRM Development requirements for those new markets were meaningfully different. We needed a partner who had solved that kind of problem before.

What services did the company provide for your project?

The full CRM Development lifecycle from discovery through to production deployment and hypercare support. This included requirements workshops, solution architecture, sprint-based development, QA and automated testing, deployment to our cloud environment, and a structured handover with documentation. They also provided a brief post-launch period of dedicated support which was genuinely useful.

Why did you choose this company over other providers you considered?

Honestly, the quality of the questions they asked during the briefing process set them apart. Most vendors listen to the brief and come back with a solution to exactly what you described. This team came back with a solution to what we actually needed, which turned out to be somewhat different. That kind of consultative instinct is what we were looking for.

How clearly did the company understand your requirements and business goals?

Extremely well. They asked detailed questions, challenged vague requirements until they were specific, and proposed sensible defaults for decisions we had not yet made rather than just leaving them open. By the time development started there was no ambiguity in the backlog, which is a rare starting position.

How was your overall experience with their communication and project management?

Professional and efficient. We used a shared project management tool that gave our stakeholders visibility without requiring them to attend every meeting. The project manager had a clear escalation path and used it appropriately. The only time I needed to intervene directly was when I chose to, not because something had been missed.

Did the company deliver the project on time and within your expected budget?

The project landed on the agreed delivery date and within the approved budget. We did add scope during the engagement — two features that became apparent as essential during user testing — and those were quoted, approved, and delivered without affecting the original scope timeline. That kind of clean change management is not something you can take for granted.

What tangible results or business impact have you seen since the project was completed?

The ROI case we presented to our board assumed a payback period of eighteen months. Based on current trajectory we will hit that in under a year. The efficiency gains in our Gaming & Gambling operations have been more significant than the model projected, partly because the quality of the data coming out of the new system is enabling decisions we could not make before.

What did you like most about working with this company?

The intellectual honesty. They told us when something we wanted was a bad idea and explained why. They told us when a timeline was tight and gave us options. They did not tell us what we wanted to hear in order to win work or avoid a difficult conversation. In a long engagement that kind of relationship is far more valuable than an agency that just says yes.

Would you recommend this company to others, and would you work with them again?

I recommend them to anyone who asks and occasionally to people who do not. The combination of CRM Development expertise, Gaming & Gambling domain knowledge, and delivery discipline is genuinely difficult to find. We found it here and we intend to keep it.
