Project delivered with the kind of professionalism that earns a long-term relationship

Daan Visser / CTO - Tulip Tech BV
Verified
May 24, 2024

Project summary: We had a clear product vision but lacked the engineering capacity internally to execute it within the window our market opportunity required.

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

Domain knowledge that went beyond generic expertise into our specific industry, willingness to push back constructively, automated test coverage that gave us deployment confidence

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.
Tulip Tech BV operates across the Construction sector with offices in Amsterdam, Netherlands. In my capacity as CTO I oversee both the strategic and operational technology agenda. We are a growth-stage business that needed a development partner capable of scaling with us rather than constraining us.
What specific problem or business challenge led you to hire this company?
Our existing POS System Development capability had accumulated years of technical debt that was slowing every new feature to a crawl. Incident frequency was rising, developer confidence was falling, and we knew a rebuild was overdue. We needed a partner with the depth to do it properly rather than apply another layer of patches.
What services did the company provide for your project?
End-to-end POS System Development delivery with a particular emphasis on the integration layer that connected the new build to our existing Construction 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?
Their portfolio included two projects that were sufficiently close to our own brief in terms of complexity, POS System Development scope, and Construction 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?
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?
The most direct measure is that the problem we hired them to solve no longer exists. Beyond that, the new POS System Development 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 post-launch behaviour. Some agencies disappear the moment the final invoice is paid. This team maintained the same level of responsiveness during the hypercare period as during development, handed over thorough documentation without being asked twice, and checked in proactively a month after go-live to review performance metrics with us. That last part was entirely unprompted.
Would you recommend this company to others, and would you work with them again?
I recommend them to anyone who asks and occasionally to people who do not. The combination of POS System Development expertise, Construction domain knowledge, and delivery discipline is genuinely difficult to find. We found it here and we intend to keep it.

Execution that matched the sales pitch — which is rarer than it should be

Rohan Malhotra / Co-Founder & CTO - Crescendo Tech Pvt Ltd

Project summary: Our competitors had been investing in technology for two years and we needed to close a meaningful gap quickly without compromising on the quality of what we shipped.

We ran a structured RFP with seven vendors. Three made it to the technical evaluation stage. This team won on the strength of their technical proposal, their domain knowledge, and frankly on the quality of the questions they asked us during the process. A vendor who asks good questions in the sales phase tends to ask good questions during delivery too. That hypothesis proved correct. The project is now live, performing above the KPIs we agreed, and our stakeholders are genuinely impressed.

PROS

Engineering quality that our internal team can maintain without calling the vendor, thorough documentation, proactive risk identification throughout the project

CONS

Premium pricing compared to some of the alternatives we evaluated, but the quality of the output and the absence of rework costs made the investment straightforward to justify

Questions & Answers

Please describe your company, your role, and the industry you operate in.
Crescendo Tech Pvt Ltd operates across the Food & Beverage sector with offices in Bangalore, India. In my capacity as Co-Founder & CTO I oversee both the strategic and operational technology agenda. We are a growth-stage business that needed a development partner capable of scaling with us rather than constraining us.
What specific problem or business challenge led you to hire this company?
The immediate trigger was a performance failure during our peak trading period that cost us measurably in both revenue and client trust. The root cause was architectural and our internal team did not have the Embedded Systems Development expertise to address it properly. We needed specialists.
What services did the company provide for your project?
End-to-end Embedded Systems Development delivery with a particular emphasis on the integration layer that connected the new build to our existing Food & Beverage 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?
Their portfolio included two projects that were sufficiently close to our own brief in terms of complexity, Embedded Systems Development scope, and Food & Beverage 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?
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?
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?
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?
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?
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.

Full-funnel digital programme that aligned our marketing and sales teams

Project summary: Visibility across our multi-tier supply chain was essentially non-existent and we were making operational decisions based on data that was 24 to 48 hours stale.

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

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.
As Chief Information Officer at Pinnacle Health Systems, I manage a cross-functional technology team serving our Logistics & Supply Chain clients from Chicago, USA. 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?
The immediate trigger was a performance failure during our peak trading period that cost us measurably in both revenue and client trust. The root cause was architectural and our internal team did not have the Digital Marketing expertise to address it properly. We needed specialists.
What services did the company provide for your project?
The full Digital Marketing 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?
Honestly, the quality of the questions they asked during the briefing process set them apart. Most vendors listen to the brief and come back with a solution to exactly what you described. This team came back with a solution to what we actually needed, which turned out to be somewhat different. That kind of consultative instinct is what we were looking for.
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?
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?
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 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 Logistics & Supply Chain 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 post-launch behaviour. Some agencies disappear the moment the final invoice is paid. This team maintained the same level of responsiveness during the hypercare period as during development, handed over thorough documentation without being asked twice, and checked in proactively a month after go-live to review performance metrics with us. That last part was entirely unprompted.
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 Digital Marketing engagement, this team is the answer.
