App store launch with a four-point-eight average rating in the first month

May 11, 2026

Project summary: An international expansion required multi-currency, multi-language, and multi-warehouse capabilities that our existing platform could not support without a fundamental re-architecture.

Six months after go-live our platform is processing three times the transaction volume we specified in the original brief. The architecture choices made during discovery accommodated that growth without remediation work. That is the difference between a team that designs for what you tell them and a team that designs for what you are likely to need. We are in conversation about a Phase 2 engagement and I expect to be using this partnership for several years.

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.

Shannon Tech Solutions Ltd is an established Retail & E-commerce organisation headquartered in Dublin, Ireland. My role as VP of Engineering 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 Retail & E-commerce market but lacked the engineering depth internally to execute it. The Mobile App 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?

End-to-end Mobile App 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 Mobile App Development approach and the evidence base they provided — reference projects in Retail & E-commerce 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?

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?

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 Mobile App Development 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 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 Retail & E-commerce sector looking for Mobile App Development expertise combined with genuine delivery discipline, I would put this team at the top of the evaluation list.

Custom modules that fit our operational processes rather than forcing us to change them

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

Apr 28, 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.

What made the most difference in practice was the quality of the engineering judgment on this team. Not the ability to execute a specification — that is a baseline expectation. The ability to recognise when a specification was suboptimal, explain why, propose an alternative, and support the client in making a decision about it. That consultative dimension elevated the output beyond what the brief described and resulted in a product that is more fit for purpose than the one we had originally specified.

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

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

Project Cost$150,000 to $499,999

Questions & Answers

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

I lead technology at Falcon Digital Ventures, a growth-stage Nonprofit & NGO business based in Dubai, UAE. As Chief Technology Officer 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?

The immediate problem was that our ERP 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?

The core engagement was ERP Development delivery, though their scope expanded to include technical consultancy during discovery that materially improved our requirements. They also took ownership of the third-party integration workstream that had been a coordination challenge in previous projects, removing that complexity from our internal team entirely.

Why did you choose this company over other providers you considered?

A trusted peer in the Nonprofit & NGO sector had used them for a comparable ERP Development engagement and their recommendation was unequivocal. Our own due diligence confirmed the pattern they described. The combination of domain knowledge, ERP Development 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?

Outstanding. The discipline around asynchronous communication was particularly effective given the time zones involved between Dubai, UAE 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?

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 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?

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?

Absolutely. With a specific note that the value starts in the discovery phase — clients who approach that process with seriousness will get the most from the engagement. We invested appropriately at the front end and the returns are evident in what was delivered.

Data engineering quality that will support our growth for years without a rebuild

Tobias Lindemann / Leiter Digitalisierung - Lindemann Industrie GmbH

Verified
Apr 26, 2026

Project summary: Our audience data was fragmented across eight tools with no single identity layer. Personalisation had become impossible without first solving the data foundation.

The integration layer was the part of the project I was most concerned about going in. Our system landscape is complex, several of the upstream APIs we relied on were poorly documented, and two third-party vendors had a history of unpredictable response times on integration questions. This team managed all of that. They documented what the upstream vendors could not, built resilience into the integration architecture where the upstream behaviour was unreliable, and delivered a solution that works as specified in production. I could not have asked for more.

PROS

Architectural decisions designed for longevity rather than just the current brief, thorough automated test coverage, post-launch stability that validated every technical choice made during discovery

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.

Lindemann Industrie GmbH is an established Media & Entertainment organisation headquartered in Berlin, Germany. My role as Leiter Digitalisierung 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 Media & Entertainment segment had changed and the compliance timeline was set by our regulator, not by us. The Data & Analytics 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?

Primarily Data & Analytics, 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?

A trusted peer in the Media & Entertainment sector had used them for a comparable Data & Analytics engagement and their recommendation was unequivocal. Our own due diligence confirmed the pattern they described. The combination of domain knowledge, Data & Analytics 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 willingness to be direct. When our requirements were unclear they said so. When our priorities were contradictory they explained why. When a technical approach we had assumed was the right one turned out to have significant downsides, they told us before we had committed to it. That kind of intellectual honesty is what I look for in a long-term technology partner.

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 Media & Entertainment network — in both cases to peers facing Data & Analytics 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: Evolving open banking obligations required us to rebuild our API layer from the ground up. The architecture needed to be compliant by default, not bolted on after the fact.

The project brief was ambitious and we had received proposals ranging from two to five times our eventual budget from other vendors. This team came back with a proposal that was commercially realistic and technically credible — and then delivered against it. That alignment between proposal and outcome is not something I take for granted. I have been on the other side of it enough times to know it requires both honesty in the sales process and discipline in delivery. We experienced both.

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.

Zenith FinServ Ltd is an established Financial Services organisation headquartered in Bangalore, India. My role as Chief Data 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?

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?

The scope covered the full Data & Analytics lifecycle: discovery and requirements definition, solution architecture, iterative development across twelve sprints, integration testing, performance validation, production deployment, and a structured four-week hypercare period. They also provided system documentation and a knowledge transfer programme for our internal team.

Why did you choose this company over other providers you considered?

A trusted peer in the Financial Services sector had used them for a comparable Data & Analytics engagement and their recommendation was unequivocal. Our own due diligence confirmed the pattern they described. The combination of domain knowledge, Data & Analytics depth, and demonstrated delivery discipline was the deciding factor.

How clearly did the company understand your requirements and business goals?

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?

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?

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.

Questions & Answers

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

As Chief Technology Officer at Nordic Cloud AB I oversee technology investment and delivery across our Travel & Hospitality operations in Stockholm, Sweden. We are a commercially focused business and our technology choices are always evaluated in terms of their direct contribution to business outcomes rather than technical elegance alone.

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.

A trusted peer in the Travel & Hospitality sector had used them for a comparable Industry-Specific Solutions engagement and their recommendation was unequivocal. Our own due diligence confirmed the pattern they described. The combination of domain knowledge, Industry-Specific Solutions 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?

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.

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

BlueSky Retail Holdings operates in the Travel & Hospitality sector with headquarters in Chicago, USA. In my role as Chief Digital Officer 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 DevOps Services 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 DevOps Services 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 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.
