Sales adopted it within the first week — no complaints, no holdouts

Étienne Marchand / CTO | May 31, 2026

This 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 funnel data made it obvious exactly where we were losing customers, and it wasn't subtle. We needed a platform capable of the experience our competitors were already delivering.

Questions & Answers

Please describe your company, your role, and the industry you operate in.
Aurora Systems Inc is a Retail & E-commerce 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?
Our CRM Development 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?
The core of it was CRM Development, though their involvement grew to include technical consulting during discovery that meaningfully sharpened our own requirements. They also took full ownership of the third-party integration work, which had been a coordination headache on past projects, and just handled it themselves.
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?
Really well, partly because they already had Retail & E-commerce 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?
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?
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?
The clearest measure is how the system's actually performing in production. In the four months since go-live we've had zero major incidents, our page performance scores improved across every Core Web Vitals metric, and two enterprise clients who'd previously flagged our old platform's limits during renewal talks signed again without raising it.
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?
Absolutely, with one caveat worth mentioning: the value really starts in discovery, so clients who take that phase seriously will get the most out of it. We put real effort in upfront and it clearly paid off in what got delivered.

This engagement shifted our culture as much as it shifted our tooling

Mahnoor Sheikh / Head of Technology | Apr 11, 2026

We 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

Buyer behavior had gone fully digital-first and our search experience had quietly become a liability. It needed to match the quality of the listings it was supposed to represent.

Questions & Answers

Please describe your company, your role, and the industry you operate in.
As Head of Technology at Chenab Digital Agency I oversee technology spend and delivery across our Real Estate operations out of Faisalabad, Pakistan. We're a commercially minded business, so every technology decision gets judged on what it actually contributes to the bottom line, not on how elegant it looks on paper.
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 DevOps Services 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 core of it was DevOps Services, though their involvement grew to include technical consulting during discovery that meaningfully sharpened our own requirements. They also took full ownership of the third-party integration work, which had been a coordination headache on past projects, and just handled it themselves.
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?
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?
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 DevOps Services 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?
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 — 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 DevOps Services program in Real Estate and expect them to actually deliver against the brief, this is the team.

Built for real-world constraints, not just for how it would read in a pitch deck

Rodrigo Cardoso / VP of Technology | Mar 30, 2026

Five 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

Our app was sitting at a 2.9-star average, and nearly every negative review mentioned the same two things: speed and how convoluted the booking flow had become.

Questions & Answers

Please describe your company, your role, and the industry you operate in.
Costa Verde Digital Ltda has been operating in Travel & Hospitality for a while now, headquartered in Rio de Janeiro, Brazil. As VP of Technology 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 Travel & Hospitality, but not the internal engineering depth to actually execute it. The Blockchain Development 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?
The core of it was Blockchain Development, though their involvement grew to include technical consulting during discovery that meaningfully sharpened our own requirements. They also took full ownership of the third-party integration work, which had been a coordination headache on past projects, and just handled it themselves.
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.

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?
Really well, partly because they already had Travel & Hospitality 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?
Genuinely excellent, especially given the time difference between Rio de Janeiro, Brazil 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?
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?

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, no hesitation. I've already referred them twice within my own Travel & Hospitality network, both times to people facing Blockchain 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.

Decisions that used to run on gut feel now run on a model we can actually explain

Margaux Lefèvre / Head of Digital Products | Mar 14, 2026

Going 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

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.
Horizon Digital SAS has been operating in Environmental Services for a while now, headquartered in Nice, France. As Head of Digital Products 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?
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?
The scope ran the full AI & Machine Learning 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 AI & Machine Learning approach was specific rather than generic, backed by actual reference projects in Environmental Services — 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?
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?
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?
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.

Smart contract audit was rigorous enough that our legal team signed off without a single note

Franziska Wagner / Chief Innovation Officer | Feb 09, 2026

What actually moved the needle wasn't their ability to follow a spec — any competent team can do that. It was their willingness to push back when a requirement didn't make sense, explain clearly why, and help us decide on something better instead. That extra layer of judgment took the final product past what we'd actually asked for and closer to what we genuinely needed, which isn't always the same thing.

Project summary

Expanding internationally meant we suddenly needed multi-currency, multi-language, and multi-warehouse support that our existing platform simply wasn't architected for.

What services did the company provide for your project?
Full Blockchain Development 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?
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.

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?
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?
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 Retail & E-commerce network, both times to people facing Blockchain 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.

Built once, felt native on both platforms — no compromise either side noticed

Nicolas Fontaine / Directeur Technique | Jan 23, 2026

Looking 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.

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 — 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.

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.
