ONE FANCY Reviews
Write a ReviewA partnership that began with a single project and earned a place on our preferred vendor list
Adriana Voss / Director of Platform Engineering - Cascadia Digital VenturesMay 30, 2026
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 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.
Deep domain knowledge that reduced the discovery overhead significantly, proactive risk identification before issues became incidents, delivery cadence that our stakeholders found reassuring
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
The team understood mobile-first thinking before we finished the brief
Beatriz Cavalcanti / Chief Digital Officer - Cerrado Tech SAMay 07, 2026
Project summary: Our campaign management workflow had grown to involve twelve different tools and significant manual reconciliation. The inefficiency was affecting both speed and accuracy.
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.
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
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
Service desk that outperformed our previous in-house team on every SLA we tracked
Liselotte Bakker / Head of Platform Engineering - Harbour Digital BVJan 10, 2026
Project summary: Time-to-market for new tariff structures had become a direct competitive disadvantage. Our product configuration layer was the bottleneck and it needed to be modernised as a priority.
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.
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

Project summary: Our company needed a reliable technology partner to deliver a complex project within a tight timeline.
This was the smoothest technology project we have ever run.

Robert Martinez / Operations Manager - Solutions GroupApr 28, 2022
Project summary: We engaged them to build a comprehensive solution addressing our core operational challenges and growth objectives.
From the discovery workshop to the final handover, the experience was seamless. The team invested real effort in understanding our business goals before writing a single line of code, and that foundation paid dividends throughout. Every milestone was hit, every deliverable was polished, and the few issues that arose were resolved before we even had to ask. The solution has already delivered measurable ROI and we are planning our next engagement with them.
Deep technical expertise, professional project management, responsive support, great value
Initial onboarding took a couple of extra days, but the team hit full stride very quickly
