E-commerce platform that cut our cart abandonment rate by a third

Project summary: Claims fraud detection had been rule-based for years and we were losing ground to more sophisticated patterns — we needed a machine learning model built on our own historical data.

The thing I appreciate most in retrospect is that they were honest when something was harder than expected. Twice during the project the team came to us proactively to say that a particular component needed more time to do properly and explained why cutting corners would create problems later. We gave them the time. Both decisions were correct. The resulting product is solid and we have had none of the post-launch instability that plagued our last two technology projects.

PROS

Technical depth across the full stack, honest and timely communication, delivered exactly what was scoped without surprise additions to the invoice

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.

Celtic Digital Ltd operates across the Insurance sector with offices in Cork, Ireland. In my capacity as Director of Engineering 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?

Our Insurance regulatory environment had changed and the compliance timeline was non-negotiable. We needed to rebuild specific components of our system to meet the new requirements and our internal team was already fully committed to the core product roadmap. Bringing in a specialist E-commerce Development partner was the only realistic path.

What services did the company provide for your project?

The full E-commerce 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?

Their portfolio included two projects that were sufficiently close to our own brief in terms of complexity, E-commerce Development scope, and Insurance context that we felt confident they understood what we were asking. The proposal was technically rigorous, the pricing was transparent, and the proposed team structure gave us senior engineers throughout rather than just for the pitch.

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

Better than we did at the start, which sounds like an exaggeration but is genuinely accurate. The discovery workshop they ran surfaced assumptions we had not examined and contradictions in our requirements that would have caused real problems mid-development. The functional specification they produced was the clearest articulation of our product that we had seen written down.

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

The project management was the best I have experienced in a vendor relationship. We had fortnightly sprint reviews with structured agendas, a shared backlog that we could inspect at any point, a risk register that was actively maintained rather than created at kickoff and never opened again, and a project manager who treated our time as something worth protecting. Communication was proactive, not reactive.

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 Insurance 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 Insurance domain where context takes time to build.

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

Absolutely. I would recommend them with a specific note that the quality of the discovery process is where the value starts. Clients who invest properly in that phase will get the most out of the engagement. We made that investment and the returns are evident in the quality of what was delivered.

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

Project summary: Our competitors had been investing in technology for two years and we needed to close a meaningful gap quickly without compromising on the quality of what we shipped.

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

Consistent delivery against milestones, code quality that passed our internal review without major findings, post-launch support that felt like a partnership not a ticket queue

CONS

We underestimated the internal resource commitment required on our side during discovery — the team warned us, we did not listen fully, and the first sprint was slower as a result

Questions & Answers

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

I lead technology at Hexagone Retail Group, a mid-sized organisation in the Sports & Fitness sector headquartered in Lyon, France. My remit as Head of Digital Products covers everything from infrastructure to product development. We had reached a point where our internal engineering capacity was not sufficient to execute our roadmap without an experienced external partner.

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

We had a product concept validated by market research but no clear path to build it within our budget and timeline constraints. Our Sports & Fitness competitors were moving quickly and we could not afford to spend eighteen months finding out a generalist agency could not execute the CRM Development work our product required.

What services did the company provide for your project?

End-to-end CRM Development delivery with a particular emphasis on the integration layer that connected the new build to our existing Sports & Fitness infrastructure. They also provided UI/UX input that was not in the original scope but which they offered proactively because they could see it would affect adoption. That kind of initiative was characteristic of how they approached the whole engagement.

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

A direct referral from a peer who had used them for a comparable CRM Development engagement in the Sports & Fitness space. That peer's experience had been excellent and their project profile was similar enough to ours that the recommendation carried real weight. Everything we found during our own evaluation reinforced that this was the right decision.

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

The requirements understanding was solid from early on, aided by the fact that they had prior experience in the Sports & Fitness sector and did not need us to explain domain context that a less experienced team would have required. That background knowledge shortened the discovery phase meaningfully and reduced the volume of clarification questions during sprints.

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

The project management was the best I have experienced in a vendor relationship. We had fortnightly sprint reviews with structured agendas, a shared backlog that we could inspect at any point, a risk register that was actively maintained rather than created at kickoff and never opened again, and a project manager who treated our time as something worth protecting. Communication was proactive, not reactive.

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 Sports & Fitness 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 Sports & Fitness 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 CRM Development engagement, this team is the answer.

Prototype-to-handoff process that our developers actually appreciated

Project summary: Our competitors had been investing in technology for two years and we needed to close a meaningful gap quickly without compromising on the quality of what we shipped.

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

Collaborative working style that made them feel like an extension of our team, excellent written communication for our async timezone relationship, clean and readable codebase

CONS

Their calendar books up quickly which made scheduling the initial kickoff slightly challenging — a good problem for them to have and not one that affected our delivery

Questions & Answers

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

I lead technology at Karachi Software House, a mid-sized organisation in the Aerospace & Defense sector headquartered in Karachi, Pakistan. My remit as Co-Founder & CEO covers everything from infrastructure to product development. We had reached a point where our internal engineering capacity was not sufficient to execute our roadmap without an experienced external partner.

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

Our existing UI/UX Design capability had accumulated years of technical debt that was slowing every new feature to a crawl. Incident frequency was rising, developer confidence was falling, and we knew a rebuild was overdue. We needed a partner with the depth to do it properly rather than apply another layer of patches.

What services did the company provide for your project?

End-to-end UI/UX Design delivery with a particular emphasis on the integration layer that connected the new build to our existing Aerospace & Defense infrastructure. They also provided UI/UX input that was not in the original scope but which they offered proactively because they could see it would affect adoption. That kind of initiative was characteristic of how they approached the whole engagement.

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

Their portfolio included two projects that were sufficiently close to our own brief in terms of complexity, UI/UX Design scope, and Aerospace & Defense context that we felt confident they understood what we were asking. The proposal was technically rigorous, the pricing was transparent, and the proposed team structure gave us senior engineers throughout rather than just for the pitch.

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

The requirements understanding was solid from early on, aided by the fact that they had prior experience in the Aerospace & Defense sector and did not need us to explain domain context that a less experienced team would have required.

What did you like most about working with this company?

The quality of the written communication. This matters more than most clients articulate. Clear, concise, technically accurate updates that our non-technical stakeholders could read and understand. Proposals and change requests that made the decision obvious rather than obscuring it in jargon. That communication quality reduced our internal coordination overhead significantly.

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

Yes, without qualification. I have already made two direct referrals to peers in the Aerospace & Defense sector who were facing similar UI/UX Design challenges. In both cases I gave the recommendation specifically because I was confident the experience would match what I described — which is a level of confidence I do not extend lightly.
