Web platform that turned our digital presence from a cost centre into a revenue driver

Apr 04, 2026

Project summary: The project had a board-facing delivery date tied to a strategic initiative. We needed a partner who would treat that date as their own, not ours.

Six months after go-live our platform is processing three times the transaction volume we specified in the original brief. The architecture choices made during discovery accommodated that growth without remediation work. That is the difference between a team that designs for what you tell them and a team that designs for what you are likely to need. We are in conversation about a Phase 2 engagement and I expect to be using this partnership for several years.

PROS

Delivery timeline that proved achievable rather than optimistic, estimation accuracy that reflected real analysis rather than competitive bidding, scope discipline that prevented the feature creep we had experienced before

CONS

Their discovery process is more rigorous than we were accustomed to and required more preparation from our side than we had initially allocated — but the quality of what followed justified every hour of it

Questions & Answers

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

I lead technology at Wisła Software Sp zoo, a growth-stage Nonprofit & NGO business based in Warsaw, Poland. As Head of Development my remit spans product engineering, platform operations, and strategic vendor partnerships. We had reached an inflection point where our internal capacity was not sufficient to execute our roadmap at the pace our market required.

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

We had a defined product vision for our next phase of growth in the Nonprofit & NGO market but lacked the engineering depth internally to execute it. The Web Development requirements in particular required specialist experience that we could not realistically recruit for on the timeline our business plan required.

What services did the company provide for your project?

The core engagement was Web Development delivery, though their scope expanded to include technical consultancy during discovery that materially improved our requirements. They also took ownership of the third-party integration workstream that had been a coordination challenge in previous projects, removing that complexity from our internal team entirely.

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

We had a failed engagement behind us and were more rigorous in our selection process as a result. We asked detailed questions about how they managed scope change, how they handled estimation, and how they communicated problems. The answers were specific, evidenced, and consistent across the team members we spoke to. That gave us confidence that the process was real rather than rehearsed.

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

Better than we managed ourselves going in. The workshops they facilitated surfaced assumptions we had not examined and exposed three requirements that were in direct conflict with each other. Resolving those before development began saved us what would certainly have been significant rework later in the project.

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

Professional and efficient. The project manager maintained a clear view of the critical path at all times and communicated changes to it transparently. The one significant scope adjustment we made mid-project was handled through a clean change request process — fairly priced, clearly documented, and absorbed without disrupting the overall timeline.

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

The project landed on time. The budget was managed within the agreed ceiling, which included one client-driven scope addition that was quoted fairly and handled without affecting the original delivery stream. The discipline around budget transparency throughout meant there was no surprise at invoice stage.

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

Quantifying the impact precisely is complicated by other variables in our business, but the metrics we can attribute directly to the Web Development work are meaningful: session duration up, conversion rate up, error rate down, and our NPS for the digital touchpoint has improved by eleven points. Our account managers report that the new capability is coming up positively in client conversations.

What did you like most about working with this company?

The post-launch behaviour. Some vendors consider go-live to be the end of their professional obligation. This team treated it as the transition to a different kind of engagement. The hypercare period was substantive, the documentation was thorough and genuinely useful, and they checked in proactively at the thirty-day and ninety-day marks to review production metrics with us.

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

Absolutely. With a specific note that the value starts in the discovery phase — clients who approach that process with seriousness will get the most from the engagement. We invested appropriately at the front end and the returns are evident in what was delivered.

A technology investment that delivered returns ahead of the business case we approved

Project summary: Several years of incremental development had left us with a platform that was technically functional but strategically limiting. A structured rebuild was the agreed path forward.

I came into this engagement as a sceptic. We had been through a failed implementation with a previous vendor and I had high standards for what evidence of competence looked like before I would trust a partner with our core systems. This team earned that trust progressively — through the quality of the discovery documentation, the rigour of the technical proposals, the consistency of the sprint deliveries, and ultimately the stability of the production system. I no longer lead with scepticism when recommending them.

PROS

Clear and consistent communication adapted appropriately for both technical and non-technical stakeholders, shared tooling that gave our team real-time visibility, reliable sprint delivery throughout

CONS

Their discovery process is more rigorous than we were accustomed to and required more preparation from our side than we had initially allocated — but the quality of what followed justified every hour of it

Project Cost$500,000+

DurationSep 2025 – Jan 2026

Questions & Answers

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

I lead technology at Cerrado Tech SA, a growth-stage Aerospace & Defense business based in Brasília, Brazil. As Chief Digital Officer my remit spans product engineering, platform operations, and strategic vendor partnerships. We had reached an inflection point where our internal capacity was not sufficient to execute our roadmap at the pace our market required.

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

Our platform had been maintained by a previous vendor for three years and the accumulated technical debt had reached a point where delivery velocity had dropped to a fraction of what it should have been. We needed fresh engineering expertise and a structured plan to address the underlying issues.

What services did the company provide for your project?

Primarily POS System Development, with adjacent work in solution architecture and quality assurance. They were responsible for the full build from requirements through to go-live, including integration with four existing systems in our technology landscape. The breadth they covered without requiring additional vendors was commercially and logistically valuable.

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

The quality of the questions they asked during the briefing process was the first indicator. Vendors who ask precise questions in the sales phase tend to apply the same rigour during delivery. That hypothesis proved accurate. The technical proposal was substantive, the team structure was senior throughout, and the pricing was transparent.

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

Thoroughly and precisely. The requirements document they produced was detailed enough that our QA team used it directly to write acceptance criteria. Every user story had a defined business objective attached. Nothing was left to interpretation. That discipline in the requirements phase paid dividends throughout development and testing.

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

Communication was proactive, timely, and appropriately calibrated. Technical updates for the engineering audience, executive summaries for the steering group, risk flags with proposed mitigations rather than just problem statements. The fortnightly sprint reviews gave our stakeholders visibility without requiring them to attend every working session.

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

The project landed on time. The budget was managed within the agreed ceiling, which included one client-driven scope addition that was quoted fairly and handled without affecting the original delivery stream. The discipline around budget transparency throughout meant there was no surprise at invoice stage.

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

The most direct measure is the performance of the system in production. In the five months since go-live we have had zero P1 incidents, our page performance scores have improved across every Core Web Vitals metric, and two enterprise clients who had cited our previous platform limitations during contract negotiations have since renewed without that objection arising.

What did you like most about working with this company?

The continuity of the team. The engineers who participated in the discovery sessions were the engineers who built the system. That consistency of institutional knowledge across a six-month project has a value that is difficult to quantify but easy to notice when it is absent. Every conversation built on the previous ones.

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

Yes. I would add the context that this is not the cheapest option in the market and they are selective about the engagements they take on. If your primary criterion is price, there are alternatives. If you want a technology partner who can be trusted with a complex POS System Development programme in the Aerospace & Defense space and will deliver against a serious brief, this is the team.

Questions & Answers

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

We are a IT Director-led organisation operating in the Mining & Metals sector. My role involves overseeing strategic technology decisions and vendor partnerships. We have been growing steadily and needed a trusted partner to help us scale our digital capabilities.

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

Our primary challenge was modernising our Mining & Metals operations through Blockchain Development. Legacy systems were limiting our agility and we needed a solution that could scale with our growth ambitions and integrate with our existing infrastructure.

What services did the company provide for your project?

They delivered a comprehensive Blockchain Development engagement covering requirements analysis, solution architecture, full-cycle development, QA testing, deployment, and post-launch support. The scope was well-defined and executed without scope creep.

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

Their demonstrated expertise in Blockchain Development and a strong portfolio of Mining & Metals projects set them apart during our evaluation. The discovery call gave us confidence they truly understood our domain, not just the technology.

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

Exceptionally well. They ran a structured discovery process, asked insightful questions, and produced a detailed requirements document that captured nuances we hadn't even articulated ourselves. That foundation made the entire project smoother.

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

Outstanding. We had a dedicated project manager, weekly status calls, a shared project board, and same-day responses to queries. There were no surprises — risks were flagged early and resolved before they became issues.

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

Yes, the project was delivered on the agreed date and within budget. Their estimates were realistic and they managed scope carefully, flagging any potential changes before they impacted the timeline or cost.

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

Significant. Since go-live we have seen measurable improvements in operational efficiency, customer satisfaction scores have risen, and the solution has already paid back a substantial portion of the investment. The team built something we are genuinely proud of.

What did you like most about working with this company?

Their genuine investment in our success. They didn't just execute a spec — they brought ideas, challenged assumptions, and cared about the outcome as much as we did. The quality of the codebase and documentation also stood out.

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

Absolutely and without hesitation. We have already referred two colleagues, and we are actively scoping the next phase of work with them. They are our go-to partner for Blockchain Development projects going forward.
