Our SRE team now points new hires to this setup as the reference example
Bartosz Nowicki / Head of Development | Jun 11, 2026The easiest thing to praise is the technical output itself — solid test coverage, a deployment pipeline that just works, documentation that people actually reference instead of ignoring. But what I keep coming back to is the number of conversations we haven't had to have since launch. No 2am incident calls. No emergency patches. No post-mortems about what went sideways. That absence is really the whole pitch, if you ask me.
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.
Wełna Software Sp zoo is a Travel & Hospitality business headquartered in Kraków, Poland. As Head of Development 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 previous vendor had maintained this platform for a few years, and the technical debt had piled up to the point where our delivery speed had dropped to a fraction of what it used to be. We needed fresh engineering eyes and an actual plan to deal with the underlying mess.
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.
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?
Very well. The discovery phase was more thorough than anything we'd been through with prior vendors. They pushed back on requirements that were vague or contradictory, suggested better alternatives where our own thinking was limited, and produced a spec our internal stakeholders agreed was the clearest version of the product they'd ever seen written down.
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 Cloud 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?
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?
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.
Consolidated seven legacy systems down into one coherent data model
Percy Wren / Director of eCommerce | Jun 08, 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.

Questions & Answers
Please describe your company, your role, and the industry you operate in.
Wren & Holt Retail PLC is a Travel & Hospitality business headquartered in Birmingham, UK. As Director of eCommerce 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 ERP Development 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?
Mainly ERP 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 Travel & Hospitality space had used them for something similar in ERP Development and recommended them without hesitation. Our own due diligence backed that up. Domain knowledge, ERP 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?
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?
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 Travel & Hospitality network, both times to people facing ERP 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.
Went from whitepaper to mainnet without a single incident worth mentioning
Delphine Rousseau / Director of Platform Engineering | May 14, 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
Audience data was scattered across eight different tools with no shared identity layer. Personalization was never going to work until that foundation got fixed first.

Questions & Answers
Please describe your company, your role, and the industry you operate in.
As Director of Platform Engineering at Pacific Crest Ventures I oversee technology spend and delivery across our Media & Entertainment operations out of Vancouver, Canada. 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?
Our Blockchain 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?
Mainly Blockchain 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?

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?
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?
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 Blockchain Development program in Media & Entertainment and expect them to actually deliver against the brief, this is the team.
Time-to-publish dropped from days to under an hour
Cormac Whelan / VP of Engineering | May 03, 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.
Project summary
Grid modernization funding required us to prove demand-response capability. The models existed on paper — we needed engineers to actually build and run them in production.

Questions & Answers
Please describe your company, your role, and the industry you operate in.
Liffey Tech Solutions Ltd is a Energy & Utilities business headquartered in Cork, Ireland. As VP 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?
We had a clear product direction for our next stage of growth in Energy & Utilities, but not the internal engineering depth to actually execute it. The CMS 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?
Full CMS 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?
The questions they asked during the briefing stage told us most of what we needed to know. Vendors who ask sharp questions during sales tend to bring that same rigor into delivery, and that held up. The technical proposal had real substance, the team was senior from the start, and the pricing was straightforward.
How clearly did the company understand your requirements and business goals?
Really well, partly because they already had Energy & Utilities 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 Cork, Ireland 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?
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 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.
Performance testing caught a latency problem three weeks ahead of our busiest traffic day
Rashid Al-Marzouqi / Chief Technology Officer | Apr 02, 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.

Domain knowledge, Quality Assurance & Testing 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?
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?
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.

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 Quality Assurance & Testing program in Advertising & Marketing and expect them to actually deliver against the brief, this is the team.
Took our security posture from a known weakness to something we now lead with in sales calls
Agnieszka Zielińska / CTO | Feb 07, 2026I went into this engagement genuinely skeptical. A previous vendor had left us with a system that technically worked but that nobody trusted, and I wasn't interested in repeating that experience. This team earned trust the slow way — solid discovery documentation, technical proposals that held up under scrutiny, sprints that landed when promised, and ultimately a production system that has simply behaved. I don't open conversations about them with caveats anymore.
Project summary
This project had a board-facing deadline tied to a wider strategic push. We needed a partner who'd treat that date like it was their own problem, not just ours.

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.

Editorial team adopted this without escalating a single support ticket
Aoibhinn Molloy / Director of Product | Jan 02, 2026What 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
The handoff between our clinic system and our patient app kept breaking in the same places. We needed a partner willing to own that integration end to end, not just patch it again.

Questions & Answers
Please describe your company, your role, and the industry you operate in.
Barrow Digital Ltd has been operating in Healthcare for a while now, headquartered in Galway, Ireland. As Director of Product 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 previous vendor had maintained this platform for a few years, and the technical debt had piled up to the point where our delivery speed had dropped to a fraction of what it used to be. We needed fresh engineering eyes and an actual plan to deal with the underlying mess.
What services did the company provide for your project?
The scope ran the full CMS Development 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 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?
Very well. The discovery phase was more thorough than anything we'd been through with prior vendors. They pushed back on requirements that were vague or contradictory, suggested better alternatives where our own thinking was limited, and produced a spec our internal stakeholders agreed was the clearest version of the product they'd ever seen written down.
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 CMS Development 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?
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 Healthcare looking for real CMS Development depth paired with actual delivery discipline should have this team near the top of their list.
