Results that made the business case look conservative in hindsight

Project summary: Our existing platform had grown organically over several years and the accumulated technical debt was beginning to affect both performance and our ability to ship new features.

Our previous agency had given us a platform that worked well enough to demo and fell apart under real load. This team came in, diagnosed the root causes accurately, and rebuilt the critical components without disrupting the live service. The performance improvements were immediate and measurable — page load times dropped by 60 percent, error rates dropped to near zero, and our support team has far fewer incidents to deal with. The contrast with our previous experience could not have been sharper.

PROS

Senior engineers on our account throughout the entire project rather than a bait-and-switch to juniors after contract signing, transparent reporting, realistic estimates that proved accurate

CONS

The initial project brief document they required was more detailed than we were used to providing, but in hindsight that rigour was part of why the project ran so smoothly

Questions & Answers

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

As CTO at Krakow Tech Studio, I manage a cross-functional technology team serving our Nonprofit & NGO clients from Krakow, Poland. We are a commercially focused organisation and every technology decision we make is evaluated against a clear business case. We needed a partner who understood that context, not just the technical brief.

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

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

What services did the company provide for your project?

The core engagement was Embedded Systems Development but expanded to include technical consultancy during the discovery phase, which helped us refine the requirements significantly before development began. They also took responsibility for coordinating with our third-party data providers, which removed a significant coordination burden from our internal team.

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

We evaluated four vendors in total. Two were eliminated after the technical assessment stage because their proposed architectures showed a surface-level understanding of what we needed. This team's proposal demonstrated genuine depth in Embedded Systems Development and specific knowledge of the Nonprofit & NGO sector that the others could not match. The reference calls confirmed a consistent pattern of delivery.

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 Nonprofit & NGO 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?

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

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

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

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

The ROI case we presented to our board assumed a payback period of eighteen months. Based on current trajectory we will hit that in under a year. The efficiency gains in our Nonprofit & NGO 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 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 Nonprofit & NGO sector who were facing similar Embedded Systems Development 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.

Project summary: Our growth into new markets required a multi-currency, multi-language commerce platform that our previous vendor had promised but never delivered.

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

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.

I lead technology at Sunrise Commerce KK, a mid-sized organisation in the Retail & E-commerce sector headquartered in Osaka, Japan. My remit as Head of Product Development 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 Retail & E-commerce 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 Quality Assurance & Testing partner was the only realistic path.

What services did the company provide for your project?

End-to-end Quality Assurance & Testing delivery with a particular emphasis on the integration layer that connected the new build to our existing Retail & E-commerce 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?

We evaluated four vendors in total. Two were eliminated after the technical assessment stage because their proposed architectures showed a surface-level understanding of what we needed. This team's proposal demonstrated genuine depth in Quality Assurance & Testing and specific knowledge of the Retail & E-commerce sector that the others could not match. The reference calls confirmed a consistent pattern of delivery.

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

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

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

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

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

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?

Hard to isolate precisely because several factors changed simultaneously, but the data we can attribute directly to the new Quality Assurance & Testing platform shows a meaningful improvement in the metrics that matter to our Retail & E-commerce business. Our account managers report that the new capability is coming up positively in client conversations, which was one of the strategic objectives we started with.

What did you like most about working with this company?

Their ability to hold the business objective in mind alongside the technical task. I have worked with technically excellent agencies who lost the thread of what we were actually trying to achieve. This team never did. Every architectural decision, every trade-off conversation, every prioritisation discussion was anchored to the outcome we had agreed at the start.

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 Quality Assurance & Testing engagement, this team is the answer.
