3 SIDED CUBE Reviews
Write a ReviewSecurity team that communicated findings clearly to non-technical stakeholders — genuinely rare
Declan Hartley / Chief Digital Officer - Southern Cross TechnologyJun 08, 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 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.
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
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

Web3 architecture designed for the real world, not just for the pitch deck
Victoria Haines / Chief Product Officer - Solaris Media GroupJun 06, 2026
Project summary: Matter management had become a significant overhead for our fee earners. Every hour spent on administration was an hour not spent on billable advisory work — the business case was straightforward.
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.
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

Penetration test that found things our previous vendor had missed for two consecutive years
Elliot Thorne / Managing Director, Tech - Redwood Capital AdvisorsMar 28, 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.

Service desk that outperformed our previous in-house team on every SLA we tracked
Lars Pfeiffer / VP of Technology - NordTech Logistik GmbHMar 11, 2026
Project summary: Integration between our clinic management system and our patient-facing app had been a recurring failure point. We needed an engineering partner who could own the integration layer end to end.
I came into this engagement as a sceptic. We had been through a failed implementation with a previous vendor and I had high standards for what evidence of competence looked like before I would trust a partner with our core systems. This team earned that trust progressively — through the quality of the discovery documentation, the rigour of the technical proposals, the consistency of the sprint deliveries, and ultimately the stability of the production system. I no longer lead with scepticism when recommending them.
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

A team that understood the difference between AI that demos well and AI that runs in prod
Beatriz Cavalcanti / Chief Digital Officer - Cerrado Tech SAMar 04, 2026
Project summary: Remote care had gone from an experiment to a core service line and our technology had not kept pace. We needed a robust, compliant telehealth platform in a timeline that the market would not wait for.
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.

Analytics infrastructure that made our data science team genuinely productive for the first time
Aarav Mehta / Chief Data Officer - Zenith FinServ LtdMar 02, 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.

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

A partnership that began with a single project and earned a place on our preferred vendor list
Erik Lindqvist / Chief Technology Officer - Nordic Cloud ABFeb 21, 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.
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.
Deep domain knowledge that reduced the discovery overhead significantly, proactive risk identification before issues became incidents, delivery cadence that our stakeholders found reassuring

Finance and operations finally speaking the same data language thanks to this team
Khalid Al-Mansoori / Chief Digital Officer - Emirates Digital GroupJan 23, 2026
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 thing I appreciate most in retrospect is that they were honest when something was harder than expected. Twice during the project the team came to us proactively to say that a particular component needed more time to do properly and explained why cutting corners would create problems later. We gave them the time. Both decisions were correct. The resulting product is solid and we have had none of the post-launch instability that plagued our last two technology projects.
Business-aware approach to every technical decision, strong project governance, fast turnaround on feedback, zero drama during a genuinely complex engagement
Premium pricing compared to some of the alternatives we evaluated, but the quality of the output and the absence of rework costs made the investment straightforward to justify

Headless CMS that finally allowed our designers and developers to work in parallel
Zofia Kamińska / CTO - Odra Tech StudioJan 14, 2026
Project summary: Our client portal had been built in 2017 and had not received meaningful investment since. Clients were contrasting it unfavourably with the portals of our competitors in pitches.
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.

Consulting engagement that saved us from a very expensive wrong decision
Arjun Kapoor / Head of Product - Skyline Retail VenturesMay 09, 2025
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.
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
Honestly nothing worth documenting — we went in with high expectations and they were met on every measure

Analytics dashboard that our executives open before their morning coffee
Courtney Walsh / Director of eCommerce - Summit Retail GroupFeb 14, 2024
Project summary: Production downtime was costing us significantly each quarter and our existing monitoring infrastructure had no predictive capability whatsoever.
I am a demanding client. I have a technical background, I review code, and I have high standards for documentation and testing. This team met all of those expectations without ever seeming defensive about scrutiny. Peer code reviews were welcomed, unit test coverage was genuine rather than performative, and the API documentation was thorough enough that our own developers integrated against it without a single clarification call. That level of craft is what I look for and rarely find.
Architectural decisions that will serve us for years rather than just solving the immediate problem, knowledge transfer that left our team genuinely capable, no scope creep at all

Project delivered with the kind of professionalism that earns a long-term relationship
Ciarán Murphy / CTO - Liffey Tech Solutions LtdMar 05, 2022
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.
Project governance was one of the things that impressed me most. We had a dedicated project manager who ran tight fortnightly sprints with clear acceptance criteria, a shared backlog that gave us full visibility at all times, and a change request process that was fair and transparent. Nothing slipped through the cracks, no bill shock at the end, and the final delivery matched the original scope document almost perfectly. In my experience that kind of discipline is genuinely uncommon.
