Would happily work with them again

Darragh Walsh / CEO | Sep 08, 2026

We were very happy with how this project went. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. When we changed our minds on a couple of features halfway through, they handled it without fuss and were clear about the impact on cost and timeline.

We are already seeing better numbers than before the project. I would recommend DeveloperX I/O to anyone looking for a dependable Web Development partner.

Project summary

DeveloperX I/O was brought in to redesign and rebuild our company website on a modern stack. Scope included discovery workshops, development in two-week sprints and a short support period after launch. Overall it was a 8-month engagement.

Reliable Web Development Partner That Delivered What They Promised

Derek Morgan / Head of Product | Mar 30, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. We dealt with the same core team throughout, so we did not have to keep re-explaining things. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. They were upfront about what was realistic within our budget, which helped us prioritise the right features.

It has made a real difference to how our team works day to day. If you need a team that communicates well and delivers, they are a good choice.
