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.
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
Honestly nothing worth documenting — we went in with high expectations and they were met on every measure

Questions & Answers
Please describe your company, your role, and the industry you operate in.
Sunrise Commerce KK operates across the Environmental Services sector with offices in Osaka, Japan. In my capacity as Head of Product Development 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?
We had a product concept validated by market research but no clear path to build it within our budget and timeline constraints. Our Environmental Services competitors were moving quickly and we could not afford to spend eighteen months finding out a generalist agency could not execute the IT Managed Services work our product required.
What services did the company provide for your project?
The full IT Managed Services 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?
Their portfolio included two projects that were sufficiently close to our own brief in terms of complexity, IT Managed Services scope, and Environmental Services 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?
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?
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?
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 Environmental Services 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 Environmental Services sector who were facing similar IT Managed Services 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.
ERP implementation that went live on schedule — rare in this category and we know it

Project summary: The project had both a hard delivery date tied to a board commitment and a scope that our previous agency had told us was not achievable. We needed someone to prove otherwise.
The technical quality of the work is the easiest thing to praise, but what I want to highlight is the communication culture on this team. Every question got a same-day response. Every risk got flagged before it became an issue. When we needed to change direction mid-project — a business decision on our side — they absorbed the change professionally, requoted fairly, and kept momentum going. That flexibility is something you cannot assess in a proposal and it turned out to be one of the most valuable things about working with them.
PROS
Engineering quality that our internal team can maintain without calling the vendor, thorough documentation, proactive risk identification throughout the project
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.
Becker Industrie GmbH is a Environmental Services business based in Munich, Germany. As Head of Digitalisation 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?
Our existing ERP 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?
Primarily ERP 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, ERP Development scope, and Environmental Services 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?
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?
Communication was handled primarily asynchronously given the time zone difference between Munich, Germany 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?
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?
Hard to isolate precisely because several factors changed simultaneously, but the data we can attribute directly to the new ERP Development platform shows a meaningful improvement in the metrics that matter to our Environmental Services 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?
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 Environmental Services domain where context takes time to build.
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 Environmental Services sector who were facing similar ERP 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.
Immersive experience that stopped people in their tracks at our launch event

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.
The thing I appreciate most in retrospect is that they were honest when something was harder than expected. Twice during the project the team came to us proactively to say that a particular component needed more time to do properly and explained why cutting corners would create problems later. We gave them the time. Both decisions were correct. The resulting product is solid and we have had none of the post-launch instability that plagued our last two technology projects.
PROS
Technical depth across the full stack, honest and timely communication, delivered exactly what was scoped without surprise additions to the invoice
CONS
Their calendar books up quickly which made scheduling the initial kickoff slightly challenging — a good problem for them to have and not one that affected our delivery

Questions & Answers
Please describe your company, your role, and the industry you operate in.
Summit Retail Group is a Mining & Metals business based in New York, USA. As Director of eCommerce 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?
Our Mining & Metals 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 AR/VR Development partner was the only realistic path.
What services did the company provide for your project?
The full AR/VR Development 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?
Thorough and precise. They translated our business language into technical requirements without losing the intent, which is a skill that sounds straightforward but frequently goes wrong. Every user story they wrote was reviewed against the original business objective before it entered the sprint and the acceptance criteria were specific enough to remove subjectivity from QA.
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?
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?
We went live three months ago. In that time we have not had a single P1 incident, our page performance scores have improved across every measure, and the feature we had deprioritised for years because the old architecture made it too complex to implement is now in our next sprint. The platform they built has opened up our roadmap in a way we had not anticipated.
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?
I recommend them to anyone who asks and occasionally to people who do not. The combination of AR/VR Development expertise, Mining & Metals domain knowledge, and delivery discipline is genuinely difficult to find. We found it here and we intend to keep it.
