HashEx Reviews
Write a ReviewE-commerce build that united our digital and in-store inventory for the first time
Shreya Krishnaswamy / VP of Product - Luminar Tech Pvt LtdMay 11, 2026
Project summary: An international expansion required multi-currency, multi-language, and multi-warehouse capabilities that our existing platform could not support without a fundamental re-architecture.
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.
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
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

A technology investment that delivered returns ahead of the business case we approved
Reuben Loh / CTO - Marina Bay Ventures Pte LtdApr 09, 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.
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
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

Implementation delivered with the discipline, documentation, and change management it required
Matthieu Renard / Directeur Technique - Lumière Technologies SASFeb 02, 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.
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.
Deep domain knowledge that reduced the discovery overhead significantly, proactive risk identification before issues became incidents, delivery cadence that our stakeholders found reassuring
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

Online store that our fulfilment and finance teams are as happy with as our customers are
Sebastian Lapointe / CTO - Boreal Systems IncJan 08, 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.
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.
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
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

Outstanding service and exceptional results
Matthew Harris / COO - Logistics InternationalJan 30, 2024
Project summary: Our company needed a reliable technology partner to deliver a complex project within a tight timeline.
From day one, the team felt like an extension of our own organisation. They immersed themselves in our domain, challenged us to think bigger, and delivered a solution that is both technically sound and strategically valuable. The project came in on time and within budget, which is rare for an engagement of this complexity. We are delighted with the outcome and look forward to a long-term partnership.

Exceptional DevOps expertise — our deployments are now effortless
William Brown / Senior Consultant - Brown ConsultingDec 15, 2023
Project summary: We required a custom platform that would give us a measurable competitive advantage in our market.
This was the smoothest technology project we have ever run. The team's expertise was evident from the first technical discussion, and their ability to translate complex requirements into elegant solutions is remarkable. They kept us informed at every step, flagged risks early, and delivered a high-quality product that our internal team is proud to maintain. Their ongoing support has been equally impressive.

Marcus Johnson / Creative Director - NYC Digital AgencyFeb 16, 2022
Project summary: Our media company needed a digital asset management system and publishing workflow automation.
Working with this team was genuinely refreshing. They brought creative ideas to the table, executed them with precision, and managed the project with a level of professionalism we rarely see. Feedback was acted on quickly, the documentation is excellent, and the end product has transformed how we operate. Our customers have noticed the difference immediately. We have already recommended them to three other companies in our network.
