They clearly understood the gap between an AI demo and an AI that survives production
Nicolas Fontaine / Directeur Technique | Jun 11, 2026Going in, the integration work was what worried me most. Our systems landscape is messy, a couple of the third-party APIs we depend on are barely documented, and one of those vendors has a well-earned reputation for slow, inconsistent support. This team absorbed all of that. They documented what the upstream providers wouldn't, built in resilience wherever the upstream behavior was flaky, and shipped something that has worked exactly as specified since go-live. I genuinely couldn't have asked for more on that front.
Project summary
Our internal engineering capacity was fully committed to keeping existing systems running, with no room for a build of this size. An outside partner with the right depth was really our only option.

Questions & Answers
Please describe your company, your role, and the industry you operate in.
Étoile Technologies SAS is a Construction business headquartered in Lyon, France. As Directeur Technique I'm responsible for the whole technology agenda — infrastructure, product, and how we pick vendors. Every decision we make on the technology side has to tie back to a clear business case before it gets approved.
What specific problem or business challenge led you to hire this company?
Our AI & Machine Learning capability had become the thing slowing everything else down. New feature requests, client asks, internal initiatives — all of it kept queuing up behind a platform that had been stretched way past what it was originally built for. We needed a proper rebuild, not another patch.
What services did the company provide for your project?
Mainly AI & Machine Learning, with some adjacent architecture and QA work folded in. They owned the whole thing from requirements to go-live, including hooking it into four of our existing systems. Not needing a second vendor to cover that ground was genuinely useful, both cost-wise and logistically.
Why did you choose this company over other providers you considered?
We shortlisted five vendors through a structured process. The technical review knocked two out right away. Of the remaining three, this team stood out because their AI & Machine Learning approach was specific rather than generic, backed by actual reference projects in Construction — not just case studies pulled off a website. The reference calls confirmed everything the proposal claimed.
How clearly did the company understand your requirements and business goals?
Thoroughly. The requirements document was detailed enough that our own QA team used it directly to build acceptance criteria. Every user story had a clear business reason attached, and nothing was left open to interpretation. That discipline early on paid off through the rest of development and testing.
How was your overall experience with their communication and project management?
Proactive and well-calibrated. Technical detail for the engineering side, plain summaries for the steering group, and risk flags that came with a proposed fix attached rather than just a problem statement. The biweekly sprint reviews kept our stakeholders in the loop without requiring them to sit in on every working session.
Did the company deliver the project on time and within your expected budget?
Yes to both. I'd quietly built in some contingency given the complexity and the number of integrations involved, and none of it ended up being needed. Delivery landed on the agreed date and the final invoice was within a rounding error of the approved budget — rarer than most people in this industry would admit.
What tangible results or business impact have you seen since the project was completed?
Hard to isolate perfectly given everything else going on in the business, but the numbers we can attribute directly to the AI & Machine Learning work are solid: session duration up, conversion up, error rate down, and our NPS for that touchpoint has moved noticeably. Our account managers say it's coming up positively in client conversations now too.
What did you like most about working with this company?
Their willingness to just be direct. If our requirements were unclear, they said so. If our priorities contradicted each other, they explained why. If an approach we'd assumed was right actually had real downsides, they told us before we'd committed to it. That kind of honesty is exactly what I look for in a long-term partner.
Would you recommend this company to others, and would you work with them again?
Yes — though I'll add that they're not the cheapest option out there and they're selective about what they take on. If price is your main filter, look elsewhere. If you need a partner you can trust with a serious AI & Machine Learning program in Construction and expect them to actually deliver against the brief, this is the team.
First time our online and in-store inventory have shown the same numbers
Étienne Marchand / CTO | Jun 08, 2026Five months post-launch, we're running at roughly double the transaction volume we'd specified in the original scope document, and the platform hasn't needed a single structural change to handle it. That's the real tell for whether a team designed for what you told them versus what you were actually going to need. We're now scoping a second phase and I expect this to be a multi-year relationship at this point.
Project summary
A previous project had worked fine in staging and fallen apart in production. We approached vendor selection this time with a lot more scrutiny as a direct result.

Questions & Answers
Please describe your company, your role, and the industry you operate in.
Aurora Systems Inc is a Fashion & Apparel business headquartered in Ottawa, Canada. As CTO I'm responsible for the whole technology agenda — infrastructure, product, and how we pick vendors. Every decision we make on the technology side has to tie back to a clear business case before it gets approved.
What specific problem or business challenge led you to hire this company?
Regulation in our Fashion & Apparel segment shifted and the compliance deadline came from the regulator, not from us. The scale of the E-commerce Development changes required justified bringing in a specialist rather than pulling our internal team off the product roadmap to handle it.
What services did the company provide for your project?
Mainly E-commerce Development, with some adjacent architecture and QA work folded in. They owned the whole thing from requirements to go-live, including hooking it into four of our existing systems. Not needing a second vendor to cover that ground was genuinely useful, both cost-wise and logistically.
Why did you choose this company over other providers you considered?
A peer in the Fashion & Apparel space had used them for something similar in E-commerce Development and recommended them without hesitation. Our own due diligence backed that up. Domain knowledge, E-commerce Development depth, and a track record of actually delivering — that combination made the decision easy.
How clearly did the company understand your requirements and business goals?
Better than we understood them ourselves, honestly. The workshops they ran surfaced assumptions we'd never questioned and exposed a few requirements that flatly contradicted each other. Sorting that out before development started saved us from what would have been serious rework later.
How was your overall experience with their communication and project management?
The most structured project management I've dealt with from any outside vendor. Sprint planning was tight, acceptance criteria were specific, and retrospectives actually led to changes rather than just being a box to tick. The backlog and risk register were both treated as live tools, not paperwork. I never once had to chase a status update.
Did the company deliver the project on time and within your expected budget?
Both, yes. One sprint hit a one-week delay from a third-party API dependency outside anyone's control. The team flagged it three weeks ahead of time, laid out two options, and we picked an approach that clawed the schedule back within the same sprint. That's the kind of foresight that separates real project management from just reacting to problems.
What tangible results or business impact have you seen since the project was completed?
We went live about three months ago. User adoption beat the target we'd set by roughly 20 percent in the first month, and support ticket volume has dropped noticeably since. Features we'd shelved because the old architecture made them too expensive to build are now back on the roadmap.
What did you like most about working with this company?
What they did after launch. A lot of vendors treat go-live as the finish line. This team treated it as the start of a different phase — the hypercare period was substantial, the documentation held up in practice, and they checked back in at the thirty and ninety day marks to go over production metrics with us unprompted.
Would you recommend this company to others, and would you work with them again?
Yes, no hesitation. I've already referred them twice within my own Fashion & Apparel network, both times to people facing E-commerce Development problems similar to ours. I made those referrals confidently because I know the experience I had was repeatable, not a one-off stroke of luck on our project.
Their pen test found gaps our previous vendor had missed two years running
Karthik Iyengar / Head of Platform | May 26, 2026We handed this team an aggressive deadline, a genuinely complicated scope, and a client-side team on our end that was stretched thin and slow to respond at times. They handled all of it without complaint. When they needed something from us they asked precisely and on time. When they didn't, they just kept moving. The project still landed on schedule despite our side being the weaker link for a good chunk of it, which tells you something about how they operate under pressure.

Questions & Answers
Please describe your company, your role, and the industry you operate in.
Novus EdTech Solutions is a Gaming & Gambling business headquartered in Coimbatore, India. As Head of Platform I'm responsible for the whole technology agenda — infrastructure, product, and how we pick vendors. Every decision we make on the technology side has to tie back to a clear business case before it gets approved.
What specific problem or business challenge led you to hire this company?
A competitor move forced our hand and compressed a roadmap item we'd planned for the following year. The Cybersecurity investment we'd scheduled twelve months out suddenly needed to happen in six, and building it internally in that window wasn't realistic.
What services did the company provide for your project?
The scope ran the full Cybersecurity lifecycle — discovery, requirements, architecture, development across roughly a dozen sprints, integration testing, performance validation, deployment, and a four-week hypercare window afterward. They also handed over full documentation and ran a knowledge transfer session for our internal team.
Why did you choose this company over other providers you considered?
We shortlisted five vendors through a structured process. The technical review knocked two out right away. Of the remaining three, this team stood out because their Cybersecurity approach was specific rather than generic, backed by actual reference projects in Gaming & Gambling — not just case studies pulled off a website. The reference calls confirmed everything the proposal claimed.
How clearly did the company understand your requirements and business goals?
Better than we understood them ourselves, honestly. The workshops they ran surfaced assumptions we'd never questioned and exposed a few requirements that flatly contradicted each other. Sorting that out before development started saved us from what would have been serious rework later.
How was your overall experience with their communication and project management?
Professional throughout. The project manager always had a clear view of the critical path and flagged changes to it honestly, without spin. The one significant scope change we made mid-project went through a clean process — fairly priced, clearly documented, and absorbed without knocking the rest of the timeline off course.
Did the company deliver the project on time and within your expected budget?
On time and inside the approved budget. Their estimating was notably accurate — they'd broken the work down in enough detail during discovery that the forecast held up the whole way through, instead of drifting with every small change. We had exactly one change request, and it was for scope we added ourselves.
What tangible results or business impact have you seen since the project was completed?
Hard to isolate perfectly given everything else going on in the business, but the numbers we can attribute directly to the Cybersecurity work are solid: session duration up, conversion up, error rate down, and our NPS for that touchpoint has moved noticeably. Our account managers say it's coming up positively in client conversations now too.

Would you recommend this company to others, and would you work with them again?
Without reservation. We're already in early conversations about a second engagement, and I expect this to turn into a multi-year relationship. Anyone in Gaming & Gambling looking for real Cybersecurity depth paired with actual delivery discipline should have this team near the top of their list.
Multi-region uptime has held above 99.9 percent since the day we went live
Marcus Teo / CTO | Mar 15, 2026We handed this team an aggressive deadline, a genuinely complicated scope, and a client-side team on our end that was stretched thin and slow to respond at times. They handled all of it without complaint. When they needed something from us they asked precisely and on time. When they didn't, they just kept moving.

Questions & Answers
Please describe your company, your role, and the industry you operate in.
Sentosa Ventures Pte Ltd has been operating in Education for a while now, headquartered in Singapore. As CTO I sit across both strategic planning and day-to-day technology delivery. We hold our vendors to a high bar because our own clients hold us to one — it's only fair to expect the same discipline from partners.
What specific problem or business challenge led you to hire this company?
We had a clear product direction for our next stage of growth in Education, but not the internal engineering depth to actually execute it. The Cloud Services piece specifically needed specialist skills we couldn't realistically hire for on the timeline our business plan demanded.
What services did the company provide for your project?
Full Cloud Services delivery, with particular depth on the integration and data migration pieces — the riskiest parts of the whole program. On top of that, they kept a dedicated QA person on the project throughout and left our operations team with a proper runbook at handover.
Why did you choose this company over other providers you considered?
A peer in the Education space had used them for something similar in Cloud Services and recommended them without hesitation. Our own due diligence backed that up. Domain knowledge, Cloud Services depth, and a track record of actually delivering — that combination made the decision easy.
How clearly did the company understand your requirements and business goals?
Really well, partly because they already had Education experience that cut down on the amount of context we had to provide. They knew the terminology, asked the right questions, and translated our business requirements into technical specs accurately enough that development barely needed any clarification cycles.
How was your overall experience with their communication and project management?
The most structured project management I've dealt with from any outside vendor. Sprint planning was tight, acceptance criteria were specific, and retrospectives actually led to changes rather than just being a box to tick. The backlog and risk register were both treated as live tools, not paperwork. I never once had to chase a status update.
Did the company deliver the project on time and within your expected budget?
The project came in on schedule. Budget stayed within the agreed ceiling, including one scope addition we asked for ourselves, which was quoted fairly and handled without disturbing the rest of the timeline. Nothing about the invoice came as a surprise.
What tangible results or business impact have you seen since the project was completed?
We went live about three months ago. User adoption beat the target we'd set by roughly 20 percent in the first month, and support ticket volume has dropped noticeably since. Features we'd shelved because the old architecture made them too expensive to build are now back on the roadmap.
What did you like most about working with this company?
Their instinct for never losing the business goal in the middle of technical decisions. I've worked with technically strong teams before who lose that thread once things get complicated. This team kept every architectural call tied back to the outcome we'd actually agreed to, which made the harder trade-off conversations a lot easier.
Would you recommend this company to others, and would you work with them again?
Yes, no hesitation. I've already referred them twice within my own Education network, both times to people facing Cloud Services problems similar to ours. I made those referrals confidently because I know the experience I had was repeatable, not a one-off stroke of luck on our project.
Improved both the outcome and the monthly cost line at the same time
Bartosz Nowicki / Head of Development | Mar 02, 2026Five months post-launch, we're running at roughly double the transaction volume we'd specified in the original scope document, and the platform hasn't needed a single structural change to handle it.

We're now scoping a second phase and I expect this to be a multi-year relationship at this point.

What services did the company provide for your project?

They also handed over full documentation and ran a knowledge transfer session for our internal team.

Took us from on-prem to cloud-native on a timeline two other vendors called unrealistic
Reem Al-Ghamdi / VP of Engineering | Feb 24, 2026Looking back, the thing that stands out most is how uneventful the whole project was. Technology projects of this size tend to generate their share of fire drills and awkward escalation calls. This one really didn't. Issues got flagged early enough that they never became incidents, scope changes went through an actual process instead of a tense phone call, and risks were tracked rather than just hoped away. That kind of quiet competence is unusual in my experience, and it made the whole thing feel easier on our end than I know it was on theirs.
Project summary
Multi-touch attribution across our media mix was the single most requested capability from clients across our whole portfolio, and we couldn't deliver it without rebuilding the data layer underneath.

Questions & Answers
Please describe your company, your role, and the industry you operate in.
I run technology for Hijaz Digital Solutions, a growth-stage Advertising & Marketing company based in Riyadh, Saudi Arabia. My role as VP of Engineering covers product engineering, platform operations, and our vendor relationships. We'd hit a point where our internal capacity just couldn't keep pace with what the roadmap demanded.
What specific problem or business challenge led you to hire this company?
Regulation in our Advertising & Marketing segment shifted and the compliance deadline came from the regulator, not from us. The scale of the Cloud Services changes required justified bringing in a specialist rather than pulling our internal team off the product roadmap to handle it.
What services did the company provide for your project?
Mainly Cloud Services, with some adjacent architecture and QA work folded in. They owned the whole thing from requirements to go-live, including hooking it into four of our existing systems. Not needing a second vendor to cover that ground was genuinely useful, both cost-wise and logistically.

They knew the terminology, asked the right questions, and translated our business requirements into technical specs accurately enough that development barely needed any clarification cycles.
How was your overall experience with their communication and project management?
Genuinely excellent, especially given the time difference between Riyadh, Saudi Arabia and the delivery team. Written updates were consistent and specific, anything needing a decision got same-day turnaround, and nothing slipped through the cracks across the whole engagement.
Did the company deliver the project on time and within your expected budget?
Yes to both. I'd quietly built in some contingency given the complexity and the number of integrations involved, and none of it ended up being needed.

A real single source of truth — rarer in practice than it sounds on paper
Matilda Osborne / Head of Engineering | Feb 11, 2026We had proposals in hand ranging from roughly half to well over double what we eventually paid this team. What set their proposal apart wasn't the price — it was that the number matched what they actually delivered, almost line for line. I've been burned before by proposals that were really just opening offers in a negotiation that continues throughout the project. That wasn't the case here, and I don't say that lightly.
Project summary
We hold vendors to the same standard our own clients hold us to, so the bar for this engagement was never going to be low. We needed a partner comfortable being measured against it.

Redgum Data Solutions is a Information Technology business headquartered in Adelaide, Australia. As Head of Engineering I'm responsible for the whole technology agenda — infrastructure, product, and how we pick vendors. Every decision we make on the technology side has to tie back to a clear business case before it gets approved.
What specific problem or business challenge led you to hire this company?
Regulation in our Information Technology segment shifted and the compliance deadline came from the regulator, not from us. The scale of the Data & Analytics changes required justified bringing in a specialist rather than pulling our internal team off the product roadmap to handle it.
What services did the company provide for your project?
The scope ran the full Data & Analytics lifecycle — discovery, requirements, architecture, development across roughly a dozen sprints, integration testing, performance validation, deployment, and a four-week hypercare window afterward. They also handed over full documentation and ran a knowledge transfer session for our internal team.
Why did you choose this company over other providers you considered?
We shortlisted five vendors through a structured process. The technical review knocked two out right away. Of the remaining three, this team stood out because their Data & Analytics approach was specific rather than generic, backed by actual reference projects in Information Technology — not just case studies pulled off a website. The reference calls confirmed everything the proposal claimed.

They knew the terminology, asked the right questions, and translated our business requirements into technical specs accurately enough that development barely needed any clarification cycles.
How was your overall experience with their communication and project management?
Proactive and well-calibrated. Technical detail for the engineering side, plain summaries for the steering group, and risk flags that came with a proposed fix attached rather than just a problem statement. The biweekly sprint reviews kept our stakeholders in the loop without requiring them to sit in on every working session.
Did the company deliver the project on time and within your expected budget?
On time and inside the approved budget. Their estimating was notably accurate — they'd broken the work down in enough detail during discovery that the forecast held up the whole way through, instead of drifting with every small change. We had exactly one change request, and it was for scope we added ourselves.
What tangible results or business impact have you seen since the project was completed?
The ROI model we took to the board was deliberately conservative. Current performance against that model puts us on track to hit payback well ahead of the eighteen-month target we set. The operational efficiency gains in particular have outpaced the model, partly because the new platform's data quality supports decisions the old system simply couldn't.
What did you like most about working with this company?
The team stayed the same the whole way through. The engineers in the discovery sessions were the same ones who built the system. That continuity matters more than people expect, and you really only notice it when it's missing. Every conversation picked up where the last one left off.
Would you recommend this company to others, and would you work with them again?
Yes, no hesitation. I've already referred them twice within my own Information Technology network, both times to people facing Data & Analytics problems similar to ours. I made those referrals confidently because I know the experience I had was repeatable, not a one-off stroke of luck on our project.
Technically sharp, commercially sensible, and genuinely easy to work with throughout
Roisin Cassidy / VP of Product Engineering | Jan 02, 2026This was our fourth agency in three years, and I say that with some embarrassment. Every previous engagement had looked promising on paper and fallen apart somewhere in delivery. What was different here was the sequencing: they spent real time understanding the actual problem before proposing anything, rather than pattern-matching to a solution they already knew how to sell. The build ran to schedule, our own engineers had genuinely positive things to say during handover, and four months into live operation we haven't had a single critical incident. We're already talking about the next phase with them.
Project summary
Our internal engineering capacity was fully committed to keeping existing systems running, with no room for a build of this size. An outside partner with the right depth was really our only option.

Questions & Answers
Please describe your company, your role, and the industry you operate in.
Silverbrook Digital Ltd has been operating in Aerospace & Defense for a while now, headquartered in Belfast, UK. As VP of Product Engineering I sit across both strategic planning and day-to-day technology delivery. We hold our vendors to a high bar because our own clients hold us to one — it's only fair to expect the same discipline from partners.
What specific problem or business challenge led you to hire this company?
Regulation in our Aerospace & Defense segment shifted and the compliance deadline came from the regulator, not from us. The scale of the Embedded Systems Development changes required justified bringing in a specialist rather than pulling our internal team off the product roadmap to handle it.
What services did the company provide for your project?
Mainly Embedded Systems Development, with some adjacent architecture and QA work folded in. They owned the whole thing from requirements to go-live, including hooking it into four of our existing systems. Not needing a second vendor to cover that ground was genuinely useful, both cost-wise and logistically.
Why did you choose this company over other providers you considered?
We were coming off a failed engagement and went into vendor selection this time with a lot more scrutiny. We asked pointed questions about how they handle scope changes, how they estimate, how they communicate bad news. The answers were specific and consistent across everyone we spoke to on their team, which gave us confidence it wasn't a rehearsed pitch.
How clearly did the company understand your requirements and business goals?
Better than we understood them ourselves, honestly. The workshops they ran surfaced assumptions we'd never questioned and exposed a few requirements that flatly contradicted each other. Sorting that out before development started saved us from what would have been serious rework later.
How was your overall experience with their communication and project management?
Professional throughout. The project manager always had a clear view of the critical path and flagged changes to it honestly, without spin. The one significant scope change we made mid-project went through a clean process — fairly priced, clearly documented, and absorbed without knocking the rest of the timeline off course.
Did the company deliver the project on time and within your expected budget?
Both, yes. One sprint hit a one-week delay from a third-party API dependency outside anyone's control. The team flagged it three weeks ahead of time, laid out two options, and we picked an approach that clawed the schedule back within the same sprint. That's the kind of foresight that separates real project management from just reacting to problems.
What tangible results or business impact have you seen since the project was completed?
The ROI model we took to the board was deliberately conservative. Current performance against that model puts us on track to hit payback well ahead of the eighteen-month target we set. The operational efficiency gains in particular have outpaced the model, partly because the new platform's data quality supports decisions the old system simply couldn't.
What did you like most about working with this company?
Their willingness to just be direct. If our requirements were unclear, they said so. If our priorities contradicted each other, they explained why. If an approach we'd assumed was right actually had real downsides, they told us before we'd committed to it. That kind of honesty is exactly what I look for in a long-term partner.
Would you recommend this company to others, and would you work with them again?
Yes — though I'll add that they're not the cheapest option out there and they're selective about what they take on. If price is your main filter, look elsewhere. If you need a partner you can trust with a serious Embedded Systems Development program in Aerospace & Defense and expect them to actually deliver against the brief, this is the team.
