Machine learning in production that the board could see working within eight weeks

Lars Pfeiffer / VP of Technology - NordTech Logistik GmbH

Apr 10, 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.

The technical quality of the final deliverable is the easiest thing to point to. The automated test coverage is thorough, the deployment pipeline is reliable, the documentation is genuinely useful rather than ceremonially produced. But the metric I keep returning to is the number of post-launch conversations we have not had to have. No incident calls at two in the morning. No emergency patches. No retrospective discussions about what went wrong. The absence of those events is the evidence I would show to someone considering this vendor.

PROS

Collaborative culture that made the team feel like a genuine extension of our organisation, strong asynchronous communication across time zones, zero-drama handling of the inevitable mid-project changes

CONS

The engagement was priced at the quality level rather than the budget level. We evaluated the alternatives and concluded that the delta was a reasonable premium for the reduction in delivery risk

Questions & Answers

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

I lead technology at NordTech Logistik GmbH, a growth-stage Events & Event Management business based in Hamburg, Germany. As VP of Technology 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?

Regulatory requirements in our Events & Event Management segment had changed and the compliance timeline was set by our regulator, not by us. The AI & Machine Learning changes required were significant enough to justify engaging a specialist partner rather than diverting our internal team from the product roadmap.

What services did the company provide for your project?

End-to-end AI & Machine Learning 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?

Comprehensively. The discovery phase they ran was more thorough than anything we had experienced with previous vendors. They challenged requirements that were vague or contradictory, proposed alternatives where our initial thinking was limiting, and produced a functional specification that our internal stakeholders agreed was the clearest articulation of the product they had seen written down.

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?

On time and within the approved budget. The estimation accuracy was notable — they had broken the work down in sufficient detail during discovery that their forecast proved reliable throughout, rather than being a number that shifted with every change in scope. We received one change request and it was for scope we had introduced ourselves.

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 AI & Machine Learning 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 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 AI & Machine Learning programme in the Events & Event Management space and will deliver against a serious brief, this is the team.

Complete rebuild that our marketing team can now manage without engineering tickets

Project summary: Our internal product thinking was strong but our execution capability in this specific technology domain was limited. We needed depth, not generalism.

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

Senior-level engineering presence throughout the entire project, not just during the pitch, honest and commercially fair handling of scope changes, codebase that our internal team praised on review

CONS

Their insistence on a detailed functional specification before development began felt like friction at the time. In retrospect, it was the reason the development phase ran without the ambiguity that has derailed similar projects for us previously

Questions & Answers

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

Lumière Technologies SAS operates in the Human Resources sector with headquarters in Paris, France. In my role as Directeur Technique 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 Web 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 Web 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?

We ran a structured shortlisting process across five vendors. The technical evaluation eliminated two immediately. Of the remaining three, this team's proposal was differentiated by the specificity of their Web Development approach and the evidence base they provided — reference projects in Human Resources contexts, not generic case studies. The reference calls confirmed a track record that the proposal had described accurately.

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?

Outstanding. The discipline around asynchronous communication was particularly effective given the time zones involved between Paris, France and the delivery team. Written updates were specific and consistent, response times were same-day for anything that required a decision, and nothing fell through the cracks across a six-month engagement.

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

Yes. I had privately built a contingency expectation into my planning given the project complexity and the number of integrations involved. None of that contingency was needed. The delivery landed on the agreed date and the final invoice matched the approved budget to within a fraction of a percent. That outcome is rarer than the industry acknowledges.

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

The ROI case we presented to our board was conservative by design. Current performance against the financial model suggests we will hit the projected payback point in under twelve months against an eighteen-month target. The operational efficiency gains in particular have exceeded the model, in part because the quality of the data the new platform generates supports decisions that the previous system could not.

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?

Unreservedly. We are in active scoping conversations for a second engagement and I expect this to develop into a multi-year partnership. For any organisation in the Human Resources sector looking for Web Development expertise combined with genuine delivery discipline, I would put this team at the top of the evaluation list.

Project summary: Multi-touch attribution across our media mix had become the most-requested capability from every client in our portfolio. We could not deliver it without rebuilding our data layer.

We had worked with three agencies before this engagement. The comparison is not flattering to the others. What distinguished this team was a systematic approach to understanding the problem before proposing a solution — something that sounds obvious and is practiced far less often than it should be. The delivery phase ran to schedule, the codebase is clean enough that our internal engineers made positive comments during handover review, and we have not logged a critical incident in five months of live operation. We intend to use them for our next phase of work.

PROS

Commercially transparent throughout — no hidden assumptions, no bill shock at the end, change requests that were fair and clearly explained rather than used as a margin-recovery mechanism

CONS

The engagement was priced at the quality level rather than the budget level. We evaluated the alternatives and concluded that the delta was a reasonable premium for the reduction in delivery risk

Questions & Answers

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

Crestline Health Partners is an established Advertising & Marketing organisation headquartered in Houston, USA. My role as Director of Digital Health covers both strategic planning and operational technology delivery. We maintain high standards for our vendors because our clients hold us to high standards — a bar we expect our partners to meet.

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 Advertising & Marketing 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?

Primarily Web 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?

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?

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?

Unreservedly. We are in active scoping conversations for a second engagement and I expect this to develop into a multi-year partnership.
