Headless CMS that finally separated our content from our presentation layer

Karolina Dabrowska / CTO - Krakow Tech Studio
Verified
Jan 19, 2025

Project summary: As an IT services firm ourselves, we needed a development partner capable of meeting the exacting standards we set for our own clients. The bar was deliberately high.

Project governance was one of the things that impressed me most. We had a dedicated project manager who ran tight fortnightly sprints with clear acceptance criteria, a shared backlog that gave us full visibility at all times, and a change request process that was fair and transparent. Nothing slipped through the cracks, no bill shock at the end, and the final delivery matched the original scope document almost perfectly. In my experience that kind of discipline is genuinely uncommon.

PROS

Consistent delivery against milestones, code quality that passed our internal review without major findings, post-launch support that felt like a partnership not a ticket queue

CONS

Time zone difference required some adjustment to our internal communication habits but the team managed the overlap window efficiently and it never affected momentum

Questions & Answers

Please describe your company, your role, and the industry you operate in.
Krakow Tech Studio is a Information Technology business based in Krakow, Poland. As CTO I am responsible for all technology investment decisions, vendor selection, and ensuring our digital capabilities match our growth ambitions. We operate in a competitive market where the quality of our software directly affects our ability to win and retain clients.
What specific problem or business challenge led you to hire this company?
Growth into new markets had exposed serious limitations in our platform. What had worked for our original user base in Krakow, Poland was not going to scale internationally, and the CMS Development requirements for those new markets were meaningfully different. We needed a partner who had solved that kind of problem before.
What services did the company provide for your project?
Primarily CMS Development, though the scope naturally touched adjacent areas. They handled architecture design, implementation, integration with our existing systems, performance testing under realistic load, and knowledge transfer to our internal team. The breadth of what they covered without requiring us to bring in additional vendors was one of the reasons the project ran efficiently.
Why did you choose this company over other providers you considered?
Their portfolio included two projects that were sufficiently close to our own brief in terms of complexity, CMS Development scope, and Information Technology context that we felt confident they understood what we were asking. The proposal was technically rigorous, the pricing was transparent, and the proposed team structure gave us senior engineers throughout rather than just for the pitch.
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?
Communication was handled primarily asynchronously given the time zone difference between Krakow, Poland and the team's base, but it was managed so well that the gap rarely felt like a constraint. Written updates were clear and timely, escalations were handled promptly, and we never had to chase for a status update. The cadence was exactly right — enough to feel informed, not so much that it created overhead.
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?
Quantitatively: user engagement metrics are up significantly since launch, our support ticket volume has dropped, and we have received unsolicited positive feedback from clients who noticed the improvement. Qualitatively: our internal team is proud of the product we now have, which affects morale and retention in ways that do not show up on a dashboard but matter enormously.
What did you like most about working with this company?
The continuity of the team. The engineers who scoped the work were the engineers who built it. That sounds like it should be standard practice but in my experience it often is not. The institutional knowledge that comes from that continuity pays dividends at every stage, particularly when you are dealing with a complex Information Technology domain where context takes time to build.
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 CMS Development engagement, this team is the answer.

Accessibility-first redesign that expanded our user base significantly

Noura Al-Rashidi / VP of Technology - Gulf Retail Holdings

Dec 06, 2024

Project summary: Our editorial team was managing content across seven different tools with no single source of truth — we needed a unified CMS that could handle structured and rich-media content equally well.

Twelve weeks from kickoff to live production deployment for a project of this complexity. I would not have believed that was achievable if I had not watched them do it. The velocity came from genuine engineering discipline — clear requirements, short feedback loops, automated testing, and a team that communicated internally without the overhead that slows most agencies down. The product has been live for four months with no critical bugs and one minor patch. We are already in scoping conversations for phase two.

PROS

Technical depth across the full stack, honest and timely communication, delivered exactly what was scoped without surprise additions to the invoice

CONS

Time zone difference required some adjustment to our internal communication habits but the team managed the overlap window efficiently and it never affected momentum

Questions & Answers

Please describe your company, your role, and the industry you operate in.
Gulf Retail Holdings is a Media & Entertainment business based in Abu Dhabi, UAE. As VP of Technology I am responsible for all technology investment decisions, vendor selection, and ensuring our digital capabilities match our growth ambitions. We operate in a competitive market where the quality of our software directly affects our ability to win and retain clients.
What specific problem or business challenge led you to hire this company?
Growth into new markets had exposed serious limitations in our platform. What had worked for our original user base in Abu Dhabi, UAE was not going to scale internationally, and the UI/UX Design requirements for those new markets were meaningfully different. We needed a partner who had solved that kind of problem before.
What services did the company provide for your project?
End-to-end UI/UX Design delivery with a particular emphasis on the integration layer that connected the new build to our existing Media & Entertainment 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?
A direct referral from a peer who had used them for a comparable UI/UX Design engagement in the Media & Entertainment space. That peer's experience had been excellent and their project profile was similar enough to ours that the recommendation carried real weight. Everything we found during our own evaluation reinforced that this was the right decision.
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?
The project management was the best I have experienced in a vendor relationship. We had fortnightly sprint reviews with structured agendas, a shared backlog that we could inspect at any point, a risk register that was actively maintained rather than created at kickoff and never opened again, and a project manager who treated our time as something worth protecting. Communication was proactive, not reactive.
Did the company deliver the project on time and within your expected budget?
Yes. I will note that the original timeline was aggressive and I had privately expected a slip. They managed to hold it by making smart sequencing decisions early on that I only fully understood in retrospect. The budget discipline was equally good — we received a single change request for scope we had introduced ourselves and it was priced fairly.
What tangible results or business impact have you seen since the project was completed?
The most direct measure is that the problem we hired them to solve no longer exists. Beyond that, the new UI/UX Design platform has reduced our operational overhead measurably, our team spends less time managing incidents and more time on product development, and we have been able to onboard two new enterprise clients who had previously cited our technical limitations as a barrier.
What did you like most about working with this company?
The intellectual honesty. They told us when something we wanted was a bad idea and explained why. They told us when a timeline was tight and gave us options. They did not tell us what we wanted to hear in order to win work or avoid a difficult conversation. In a long engagement that kind of relationship is far more valuable than an agency that just says yes.
Would you recommend this company to others, and would you work with them again?
Absolutely. I would recommend them with a specific note that the quality of the discovery process is where the value starts. Clients who invest properly in that phase will get the most out of the engagement. We made that investment and the returns are evident in the quality of what was delivered.

From proof-of-concept to production AI in a timeline that impressed our board

Project summary: Several previous vendor relationships had left us cautious. We needed a partner who would be honest about complexity upfront rather than discovering it mid-project.

Twelve weeks from kickoff to live production deployment for a project of this complexity. I would not have believed that was achievable if I had not watched them do it. The velocity came from genuine engineering discipline — clear requirements, short feedback loops, automated testing, and a team that communicated internally without the overhead that slows most agencies down. The product has been live for four months with no critical bugs and one minor patch. We are already in scoping conversations for phase two.

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

Questions & Answers

Please describe your company, your role, and the industry you operate in.
Irongate Capital is a Nonprofit & NGO business based in Atlanta, USA. As Managing Director, Tech I am responsible for all technology investment decisions, vendor selection, and ensuring our digital capabilities match our growth ambitions. We operate in a competitive market where the quality of our software directly affects our ability to win and retain clients.
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 AI & Machine Learning work our product required.
What services did the company provide for your project?
The full AI & Machine Learning lifecycle from discovery through to production deployment and hypercare support. This included requirements workshops, solution architecture, sprint-based development, QA and automated testing, deployment to our cloud environment, and a structured handover with documentation. They also provided a brief post-launch period of dedicated support which was genuinely useful.
Why did you choose this company over other providers you considered?
Price was a factor but not the deciding one. They were mid-range in our evaluation. What tipped it was the combination of their technical depth in AI & Machine Learning, the seniority of the team they proposed to assign to our account, and the clarity of their project governance model. We had been burned by an agency that overpromised before and we needed to see evidence of process maturity.
How clearly did the company understand your requirements and business goals?
Better than we did at the start, which sounds like an exaggeration but is genuinely accurate. The discovery workshop they ran surfaced assumptions we had not examined and contradictions in our requirements that would have caused real problems mid-development. The functional specification they produced was the clearest articulation of our product that we had seen written down.
How was your overall experience with their communication and project management?
Professional and efficient. We used a shared project management tool that gave our stakeholders visibility without requiring them to attend every meeting. The project manager had a clear escalation path and used it appropriately. The only time I needed to intervene directly was when I chose to, not because something had been missed.
Did the company deliver the project on time and within your expected budget?
Yes on both counts. There was one sprint where a third-party integration took longer than scoped because of undocumented API behaviour on the vendor side. The team flagged it immediately, proposed two mitigation options, and we agreed on an approach that recovered the timeline within two weeks. That is how scope issues should be handled and rarely are.
What tangible results or business impact have you seen since the project was completed?
The most direct measure is that the problem we hired them to solve no longer exists. Beyond that, the new AI & Machine Learning platform has reduced our operational overhead measurably, our team spends less time managing incidents and more time on product development, and we have been able to onboard two new enterprise clients who had previously cited our technical limitations as a barrier.
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?
Unreservedly. We are in active conversation about the next phase of work and I expect this to become a multi-year partnership. For any organisation in the Nonprofit & NGO space looking for a AI & Machine Learning partner who combines technical rigour with genuine commercial awareness, I would put this team at the top of the shortlist.
