Synesthesia Reviews
Write a ReviewA development partner who treated our roadmap as carefully as their own
Sabrina Vollmer / Chief Innovation Officer - Rheintal Digital AGMay 24, 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.
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.
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

Headless commerce architecture that gave our content and marketing teams genuine independence
Radosław Kowalczyk / Head of Development - Wisła Software Sp zooMay 05, 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.

The quality of documentation they produce means our team needed to set aside dedicated review time to do it justice — a minor scheduling point rather than a genuine criticism

Tokenisation project that went from whitepaper to mainnet without a single major incident
Sabrina Vollmer / Chief Innovation Officer - Rheintal Digital AGApr 29, 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.
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.
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

Questions & Answers
Security posture transformed from a known liability to a competitive differentiator
Rupert Ashford / Director of eCommerce - Hargrove Retail PLCMar 07, 2026
Project summary: Our mobile app had a 2.9-star average review score. The two themes in every negative review were speed and booking flow complexity — both were solvable with the right engineering partner.
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.
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
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
Tokenisation project executed with precision and deep domain understanding
Lachlan Burgess / Chief Digital Officer - Harbour Digital Pty LtdFeb 14, 2026
Project summary: Post-pandemic recovery meant rebuilding our booking infrastructure from scratch with a focus on flexibility, cancellation handling, and real-time inventory across multiple GDS providers.
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.
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
The volume of quality documentation they produced was genuinely impressive but also meant our team needed dedicated time to review it properly — a minor process point, not a complaint
Questions & Answers
Smart contract implementation rigorous enough to satisfy both our legal and security teams
Victoria Haines / Chief Product Officer - Solaris Media GroupJan 12, 2026
Project summary: Customer expectations had reset and our conversion funnel data showed precisely where we were losing them. We needed a commerce platform capable of delivering the experience our competitors already had.
We gave this team an aggressive timeline, a technically complex scope, and a client-side project team that was stretched thin and not always available at the speed the engagement required. They absorbed all of that gracefully. Where they needed input they were precise about what they needed and when. Where they could proceed independently they did. The result was a delivery that landed on time despite the constraints on our side, which I regard as evidence of genuine professional maturity.
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

Questions & Answers
Web3 expertise that felt current, not theoretical
Charlotte Whitfield / Head of Digital Commerce - Sterling Retail PLCFeb 01, 2025
Project summary: Our existing platform had grown organically over several years and the accumulated technical debt was beginning to affect both performance and our ability to ship new features.
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.
Senior engineers on our account throughout the entire project rather than a bait-and-switch to juniors after contract signing, transparent reporting, realistic estimates that proved accurate
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
Questions & Answers
Our digital storefront finally reflects the quality of our brand
Hannah Richter / Chief Innovation Officer - Rhein Digital AGNov 09, 2022
Project summary: Our property management portfolio had grown to a point where spreadsheets and disconnected tools were costing us both time and deals. We needed a single system of record.
The technical quality of the work is the easiest thing to praise, but what I want to highlight is the communication culture on this team. Every question got a same-day response. Every risk got flagged before it became an issue. When we needed to change direction mid-project — a business decision on our side — they absorbed the change professionally, requoted fairly, and kept momentum going. That flexibility is something you cannot assess in a proposal and it turned out to be one of the most valuable things about working with them.
Engineering quality that our internal team can maintain without calling the vendor, thorough documentation, proactive risk identification throughout the project
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
Questions & Answers
Finance and operations finally speaking the same data language thanks to this team
Minjun Oh / Director of Engineering - Sejong Digital CorpJun 10, 2022
Project summary: Citizen-facing services that had been paper-based for decades needed to be digitised in a way that was genuinely accessible to all demographics, not just the digitally confident.
Twelve weeks from kickoff to live production deployment for a project of this complexity. I would not have believed that was achievable if I had not watched them do it. The velocity came from genuine engineering discipline — clear requirements, short feedback loops, automated testing, and a team that communicated internally without the overhead that slows most agencies down. The product has been live for four months with no critical bugs and one minor patch. We are already in scoping conversations for phase two.
Domain knowledge that went beyond generic expertise into our specific industry, willingness to push back constructively, automated test coverage that gave us deployment confidence
Honestly nothing worth documenting — we went in with high expectations and they were met on every measure
