Upsilon Reviews

Have a look at these client reviews on previously delivered projects.

Delivered what the proposal described. More rare than it should be.

Three months post-launch our key metrics are all moving in the right direction — user adoption ahead of target, support volume down, time-on-task reduced for our core workflows. The product team has started planning features that were never viable on the previous platform. That is the real proof of the investment: it opened up possibilities rather than just replacing what was there before.

Project summary

Our client portal had not been updated since 2018. Prospects were mentioning competitor portals in pitches. We could not keep deferring the investment.

Our team stopped guessing and started deciding. That is what good ML looks like.

We handed them an aggressive deadline, a complex scope, and a client-side team that was stretched and not always available when they needed us. They handled that gracefully. They were precise about what they needed and when they needed it. Where they could proceed independently they did. The delivery landed on time in spite of the constraints we added. I regard that as strong evidence of genuine professional maturity — not just capability.

Project summary

Moving to a direct-to-consumer model required a platform capability we had never needed before. The build needed to be right the first time given the marketing spend committed to the launch.

IT partner that understands our business, not just our ticket queue

The technical quality is the obvious thing to highlight. The automated test suite is comprehensive, the deployment pipeline is solid, and the documentation is actually useful rather than written to satisfy a checklist. But the metric I keep coming back to is what has NOT happened since go-live. No 2am incident calls. No emergency patches. No post-launch retrospectives about what went wrong. For a system of this complexity, that outcome is exactly what we paid for.

Project summary

Our content delivery infrastructure worked at current scale but showed clear signs it would not survive the enrolment growth our strategic plan assumed.

ERP went live on the agreed date. Those of you who have been through ERP projects understand.

The knowledge transfer at the end of the project was notably good. Too many vendors see handover as a tick-box exercise. This team ran structured sessions, produced documentation our internal team actually references, and spent real time making sure we understood the architecture decisions well enough to maintain and extend the system independently. Six months later we are doing exactly that without needing to go back to them for every question.

Project summary

Telehealth demand had turned a pilot into a core service line faster than our technology could keep up. We needed a compliant, reliable platform and we needed it quickly.

Security team that treated our risk as their own. That ownership made all the difference.

What set this team apart in practice was their engineering judgment — specifically, their willingness to tell us when our requirements were wrong and explain what to do instead. Not every vendor does that. The consultative element elevated the final output well beyond what our original brief described. We ended up with something better than what we had asked for, which is not a sentence I expected to be writing in a review.

Project summary

A new product line required underwriting logic that our legacy system could not support without a rewrite of the rules engine. The workarounds had accumulated to the point of being unmanageable.
