Epsilon Innovations Reviews
Write a ReviewThe outcome we specified, delivered the way we needed it, by people we would hire again
Nora Al-Otaibi / VP of Engineering - Salam Digital SolutionsMay 19, 2026
Project summary: Unplanned downtime had become our single largest cost driver and our data showed that predictive maintenance could address the majority of it — if we had the right infrastructure to act on it.
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.
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
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
A development partner who treated our roadmap as carefully as their own
Gustavo Ferreira / VP of Technology - Amazônia Digital LtdaMay 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.
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.
Deep domain knowledge that reduced the discovery overhead significantly, proactive risk identification before issues became incidents, delivery cadence that our stakeholders found reassuring
We underestimated the input required from our subject matter experts during the requirements phase. The team flagged this early but our resource planning did not fully reflect it — our responsibility, not theirs
Questions & Answers
CRM integration that connected our marketing automation to our revenue motion seamlessly
Aoife Brennan / VP of Product Engineering - Emerald Digital LtdApr 26, 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.

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
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
Accessibility-first approach that broadened our audience and impressed our enterprise clients
Nisha Pillai / Director of Engineering - GrowthBridge VenturesApr 20, 2026
Project summary: Serialisation requirements under new traceability legislation had a compliance deadline. Our supply chain system required targeted development to meet it — generalist knowledge was not sufficient.
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.
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 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
Security posture transformed from a liability to a genuine sales differentiator
Allison Park / Chief Product Officer - Vertex Media IncApr 01, 2026
Project summary: Document review and contract lifecycle management were consuming a disproportionate amount of fee-earner time that should have been spent on higher-value advisory work.
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
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
Questions & Answers
Software delivery that was on time, on budget, and beyond spec
Priscilla Tan / Head of Engineering - AsiaPac FinTech Pte LtdMar 26, 2026
Project summary: Customer churn was rising and our data showed that poor self-service experience was a primary driver — we needed a wholesale rebuild of our customer portal.
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.
Technical depth across the full stack, honest and timely communication, delivered exactly what was scoped without surprise additions to the invoice
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
Commerce platform that handled peak-day traffic at twelve times normal load without incident
Sabrina Vollmer / Chief Innovation Officer - Rheintal Digital AGJan 29, 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.
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.
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
Smart contract implementation rigorous enough to satisfy both our legal and security teams
Priya Chandrasekaran / VP of Data & AI - Wavefront Analytics IncJan 14, 2026
Project summary: Our trading platform had been extended incrementally for seven years. Latency was degrading, technical debt was compounding, and a clean rebuild was no longer optional.
Six months after go-live our platform is processing three times the transaction volume we specified in the original brief.

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

Questions & Answers
Custom editorial tooling that fits how our team actually works
Faisal Al-Ghamdi / Chief Digital Officer - Riyadh Tech VenturesAug 04, 2025
Project summary: The project had both a hard delivery date tied to a board commitment and a scope that our previous agency had told us was not achievable. We needed someone to prove otherwise.
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.
Collaborative working style that made them feel like an extension of our team, excellent written communication for our async timezone relationship, clean and readable codebase
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

Gameplay mechanics implemented with the polish and feel our design doc demanded
Antoine Lefevre / Directeur Technique - Lumiere Digital SASAug 18, 2023
Project summary: Our hospital network required a unified patient data platform that could integrate with existing EMR systems while meeting all relevant data protection obligations.
