Omar Al-Farsi / Chief Technology Officer - Falcon Digital Ventures

Mar 20, 2026

Project summary: Lean manufacturing initiatives required real-time OEE data at the line level. Our existing systems could not provide it without significant manual aggregation.

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

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

Time zone coordination required some deliberate overlap management from both sides in the first couple of sprints, after which we had an efficient async rhythm that worked for the whole project

Questions & Answers

Please describe your company, your role, and the industry you operate in.
Falcon Digital Ventures is an established Manufacturing organisation headquartered in Dubai, UAE. My role as Chief Technology Officer 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?
Regulatory requirements in our Manufacturing segment had changed and the compliance timeline was set by our regulator, not by us. The Digital Marketing 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 Digital Marketing 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?
A trusted peer in the Manufacturing sector had used them for a comparable Digital Marketing engagement and their recommendation was unequivocal. Our own due diligence confirmed the pattern they described. The combination of domain knowledge, Digital Marketing depth, and demonstrated delivery discipline was the deciding factor.
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?
Communication was proactive, timely, and appropriately calibrated. Technical updates for the engineering audience, executive summaries for the steering group, risk flags with proposed mitigations rather than just problem statements. The fortnightly sprint reviews gave our stakeholders visibility without requiring them to attend every working session.
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 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. For any organisation in the Manufacturing sector looking for Digital Marketing expertise combined with genuine delivery discipline, I would put this team at the top of the evaluation list.

An honest assessment of where we were, followed by a credible plan for where we needed to go

Radosław Kowalczyk / Head of Development - Wisła Software Sp zoo

Project summary: Serialisation requirements under new traceability legislation had a compliance deadline. Our supply chain system required targeted development to meet it — generalist knowledge was not sufficient.

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

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

Their discovery process is more rigorous than we were accustomed to and required more preparation from our side than we had initially allocated — but the quality of what followed justified every hour of it

Questions & Answers

Please describe your company, your role, and the industry you operate in.
Wisła Software Sp zoo operates in the Pharmaceuticals & Biotechnology sector with headquarters in Warsaw, Poland. In my role as Head of Development 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?
Our platform had been maintained by a previous vendor for three years and the accumulated technical debt had reached a point where delivery velocity had dropped to a fraction of what it should have been. We needed fresh engineering expertise and a structured plan to address the underlying issues.
What services did the company provide for your project?
End-to-end IT Consulting 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?
A trusted peer in the Pharmaceuticals & Biotechnology sector had used them for a comparable IT Consulting engagement and their recommendation was unequivocal. Our own due diligence confirmed the pattern they described. The combination of domain knowledge, IT Consulting depth, and demonstrated delivery discipline was the deciding factor.
How clearly did the company understand your requirements and business goals?
Thoroughly and precisely. The requirements document they produced was detailed enough that our QA team used it directly to write acceptance criteria. Every user story had a defined business objective attached. Nothing was left to interpretation. That discipline in the requirements phase paid dividends throughout development and testing.
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?
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?
Quantifying the impact precisely is complicated by other variables in our business, but the metrics we can attribute directly to the IT Consulting 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 IT Consulting programme in the Pharmaceuticals & Biotechnology space and will deliver against a serious brief, this is the team.

A team that understood the difference between AI that demos well and AI that runs in prod

Liselotte Bakker / Head of Platform Engineering - Harbour Digital BV

Feb 09, 2026

Project summary: Several years of incremental development had left us with a platform that was technically functional but strategically limiting. A structured rebuild was the agreed path forward.

Our stakeholder group included board members, clinical leads, compliance officers, and end users — each with different technical literacy and different success criteria. This team navigated that stakeholder landscape as well as any vendor I have seen. They adjusted their communication register depending on the audience without losing the substance. They managed expectations honestly throughout. And they delivered a system that each group can point to as meeting their requirements. That breadth is genuinely uncommon.

PROS

Deep domain knowledge that reduced the discovery overhead significantly, proactive risk identification before issues became incidents, delivery cadence that our stakeholders found reassuring

CONS

Pipeline availability for kickoff required a few weeks of lead time — in hindsight that selection pressure means you are working with a team that is in demand for the right reasons

Questions & Answers

Please describe your company, your role, and the industry you operate in.
I lead technology at Harbour Digital BV, a growth-stage Events & Event Management business based in Utrecht, Netherlands. As Head of Platform Engineering 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?
A competitive threat had accelerated our roadmap. We had planned a significant AI & Machine Learning investment for the following year. External pressure moved that timeline forward by six months and required us to find an external partner rather than attempting to build internally in the time available.
What services did the company provide for your project?
Primarily AI & Machine Learning, 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?
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?
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?
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?
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?
Their instinct for keeping the business objective visible throughout technical decision-making. I have worked with technically excellent teams who lose the strategic thread as complexity increases. This team maintained a clear connection between every architectural choice and the outcome we had agreed to achieve. That orientation made the trade-off conversations significantly easier.
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 Events & Event Management sector looking for AI & Machine Learning expertise combined with genuine delivery discipline, I would put this team at the top of the evaluation list.

FAQs

Would Appstem be a good fit for an early-stage startup?
Generally, yes — companies like Appstem tend to work well with startups because of what they typically offer: MVP builds, product strategy input, architecture that can scale later, and dedicated teams that keep costs manageable while still moving fast. For context, it has served clients in USA, and its typical hourly rate is around $150 - $199.
Can I just hire developers from Appstem to sit alongside my own team?
Usually, yes — a dedicated developer arrangement is a common option with firms like Appstem, where you get engineers working exclusively on your project as an extension of your in-house team rather than as a separate outsourced unit. For context, it has served clients in USA, and it has experience across industries such as Retail & E-commerce, Manufacturing, Healthcare, Energy & Utilities, Media & Entertainment and Events & Event Management.
What should I actually be looking at when comparing a company like Appstem to others?
When you're weighing up a software partner such as Appstem, it's worth looking past the pitch and checking the portfolio, what past clients say, relevant industry background, technical range, how they communicate, pricing structure, project management style, and what support looks like after launch. For context, it has served clients in USA, and it has been operating since 2010.
What are the actual contract options if I want to work with Appstem?
Most companies structured like Appstem give you a choice between a fixed-price contract, a dedicated team arrangement, or time-and-materials billing, so you can pick whichever lines up with your budget and how well-defined your scope already is. For context, its listed capabilities span AR App Development, IoT App Development, Mobile App Development, UI-UX Design and VR App Development, and it has been operating since 2010.
What should I expect to pay to work with Appstem?
What Appstem charges comes down to a handful of variables — how complex the project is, the number of development hours involved, the tech stack required, team size, and which engagement model you pick. Based on available data, Appstem's typical hourly rate is around $150 - $199, with an average project cost of $10000+.
Is Appstem more of an offshore setup or a local team?
That depends on where Appstem is based and who they primarily serve — some firms like this operate fully offshore, some are local-first, and plenty run a hybrid model that mixes both. For context, it has served clients in USA, and it has been operating since 2010.
How do I actually get a real proposal out of Appstem instead of a generic reply?
The most reliable route is giving Appstem a clear, specific brief up front — through their website form, a direct email, or a call — since a vague ask tends to get a vague answer back, while a concrete one usually gets a proper estimate. For context, its listed capabilities span AR App Development, IoT App Development, Mobile App Development, UI-UX Design and VR App Development, and it has served clients in USA.
What kind of software work does Appstem take on?
