Double Digit Reviews
Write a ReviewA partnership that began with a single project and earned a place on our preferred vendor list
Yuki Hashimoto / Head of Product Development - East Asia Commerce KKJun 09, 2026
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 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.
Production system that has performed as specified since go-live without remediation work, documentation thorough enough to support internal maintenance, knowledge transfer that left our team genuinely capable
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

Performance-first web development that Google Core Vitals confirmed was the right approach
Sabrina Vollmer / Chief Innovation Officer - Rheintal Digital AGMay 12, 2026
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.
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.
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
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

Compliance programme delivered on time and approved by the regulator without remediation
Liselotte Bakker / Head of Platform Engineering - Harbour Digital BVMar 24, 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.
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
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
Immersive experience that generated more media coverage than anything we had shipped before
Priya Chandrasekaran / VP of Data & AI - Wavefront Analytics IncFeb 04, 2026
Project summary: Grid modernisation funding required us to demonstrate demand-response capability. The machine learning models existed on paper; we needed an engineering partner to build and productionise them.
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.
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

Questions & Answers
Design system that brought consistency to a product that had accrued four years of visual debt
Clémentine Aubert / Head of Digital Products - Arc-en-Ciel Digital SASJan 09, 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.
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
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

A platform our sales team adopted within the first week without a single complaint
Nora Al-Otaibi / VP of Engineering - Salam Digital SolutionsJan 07, 2026
Project summary: Our engineering capacity was committed to maintaining existing systems and could not absorb a net-new build of this complexity. An external partner with the right skills was the only viable option.
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.
Clear and consistent communication adapted appropriately for both technical and non-technical stakeholders, shared tooling that gave our team real-time visibility, reliable sprint delivery throughout
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
Penetration test that found things our previous vendor had missed for two consecutive years
Bram de Vries / Chief Technology Officer - Windmill Tech BVJan 03, 2026
Project summary: Our actuarial models had outgrown the reporting infrastructure feeding them. Data latency was introducing risk into pricing decisions that the business had decided it could no longer accept.

Compliance framework implementation that satisfied our regulator on the first review
Divya Nair / Director of Technology - BrightPath EdTechFeb 14, 2024
Project summary: Our competitors had been investing in technology for two years and we needed to close a meaningful gap quickly without compromising on the quality of what we shipped.
The engagement started with a discovery workshop that immediately signalled this team was different. They pushed back on two of our assumptions in the first session with evidence and a better alternative. That kind of intellectual honesty is rare and it set the tone for the whole project. Deliverables were consistently ahead of schedule, code reviews were taken seriously, and the final product is something we are proud to show enterprise clients during due diligence calls.
Domain knowledge that went beyond generic expertise into our specific industry, willingness to push back constructively, automated test coverage that gave us deployment confidence
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

Custom-built platform that became the backbone of our entire operation
Maximilian Schreiber / Director of IT - Schreiber Logistik GmbHAug 12, 2023
Project summary: Several previous vendor relationships had left us cautious. We needed a partner who would be honest about complexity upfront rather than discovering it mid-project.
Our previous agency had given us a platform that worked well enough to demo and fell apart under real load. This team came in, diagnosed the root causes accurately, and rebuilt the critical components without disrupting the live service. The performance improvements were immediate and measurable — page load times dropped by 60 percent, error rates dropped to near zero, and our support team has far fewer incidents to deal with. The contrast with our previous experience could not have been sharper.
Consistent delivery against milestones, code quality that passed our internal review without major findings, post-launch support that felt like a partnership not a ticket queue

Full-funnel digital programme that aligned our marketing and sales teams
Connor MacLeod / CTO - Pacific Ventures GroupMay 24, 2023
Project summary: Smart meter rollout had generated more data than our existing analytics infrastructure could process and we were losing value that should have been translating directly into grid efficiency gains.
Our industry has specific compliance requirements that many generalist agencies struggle with. This team came with working knowledge of the relevant frameworks, asked pointed questions about our obligations, and built controls into the architecture rather than bolting them on at the end. Our compliance team reviewed the delivered system and had only minor observations, which is genuinely unusual for a first-pass review. That domain awareness saved us significant remediation cost.
Business-aware approach to every technical decision, strong project governance, fast turnaround on feedback, zero drama during a genuinely complex engagement
We underestimated the internal resource commitment required on our side during discovery — the team warned us, we did not listen fully, and the first sprint was slower as a result
