Write a ReviewDistributed ledger that finally solved a trust problem we had spent three years arguing about

Project summary: A previous engagement had delivered something that worked in staging and struggled in production. We approached this project with greater rigour in vendor selection as a result.
The thing that retrospectively seems most significant is how little drama there was. Complex technology projects tend to accumulate incidents, escalations, and tense conversations. This one did not. Problems were surfaced before they became incidents. Scope changes were handled with process rather than conflict. Risks were managed rather than avoided. That level of maturity is rare in my experience and it made the delivery feel almost effortless from our side, which I know it was not from theirs.
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
The quality of documentation they produce means our team needed to set aside dedicated review time to do it justice — a minor scheduling point rather than a genuine criticism

Questions & Answers
Please describe your company, your role, and the industry you operate in.
Lindemann Industrie GmbH operates in the Gaming & Gambling sector with headquarters in Berlin, Germany. In my role as Leiter Digitalisierung I am accountable for the full technology agenda — infrastructure, product, and vendor relationships. We are a commercially driven organisation and every technology decision is evaluated against a clear business case before it is approved.
What specific problem or business challenge led you to hire this company?
The immediate problem was that our Blockchain Development capability had become the bottleneck limiting our ability to grow. Every feature request, every new client requirement, every internal initiative was delayed by a platform that had been extended beyond its original design. We needed a rebuild, not a patch.
What services did the company provide for your project?
End-to-end Blockchain Development delivery with particular depth in the integration and data migration components, which were the highest-risk elements of the programme. They supplemented this with a dedicated QA resource throughout development and a documented runbook for our operations team at handover.
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?
Extremely well, in part because they had relevant Gaming & Gambling experience that reduced the context-setting overhead significantly. They understood the domain vocabulary, asked the right questions, and translated business requirements into technical specifications with a fidelity that meant the development phase had very few clarification cycles.
How was your overall experience with their communication and project management?
The project management framework was the most structured I have experienced with an external vendor. Sprint planning was tight, acceptance criteria were specific, retrospectives were honest and acted on. The project manager treated the shared backlog as a live document and the risk register as an operational tool rather than a compliance artefact. I never had to ask for a status update.
Did the company deliver the project on time and within your expected budget?
Yes to both. There was a single sprint where a dependency on a third-party API introduced a one-week delay. The team identified it three weeks in advance, presented two mitigation options, and we agreed on an approach that recovered the schedule within the same sprint cycle. That level of foresight is what separates good project management from reactive problem management.
What tangible results or business impact have you seen since the project was completed?
We went live four months ago. User adoption exceeded the target we had set by 23 percent in the first month. Support ticket volume has dropped measurably. The features we had deferred because the previous architecture made them prohibitively expensive to build are now in development. The platform they built has opened our roadmap.
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?
Yes, without reservation. I have already made two direct referrals within my Gaming & Gambling network — in both cases to peers facing Blockchain Development challenges similar to ours. I gave those referrals with confidence because I knew the experience I described was reproducible, not the result of exceptional circumstances on our engagement.

Project summary: We required a custom platform that would give us a measurable competitive advantage in our market.
Working with this team was genuinely refreshing. They brought creative ideas to the table, executed them with precision, and managed the project with a level of professionalism we rarely see. Feedback was acted on quickly, the documentation is excellent, and the end product has transformed how we operate. Our customers have noticed the difference immediately. We have already recommended them to three other companies in our network.
PROS
Excellent communication, high-quality deliverables, on-time delivery, proactive problem-solving
CONS
Slightly higher day rate than some alternatives, but the quality justifies every penny

Questions & Answers
Please describe your company, your role, and the industry you operate in.
We are a Founder & CEO-led organisation operating in the Construction 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 Construction operations through Industry-Specific Solutions. 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 Industry-Specific Solutions 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 Industry-Specific Solutions and a strong portfolio of Construction 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 Industry-Specific Solutions projects going forward.

Project summary: Our company needed a reliable technology partner to deliver a complex project within a tight timeline.
From the discovery workshop to the final handover, the experience was seamless. The team invested real effort in understanding our business goals before writing a single line of code, and that foundation paid dividends throughout. Every milestone was hit, every deliverable was polished, and the few issues that arose were resolved before we even had to ask. The solution has already delivered measurable ROI and we are planning our next engagement with them.
