Ultraviolet Lab Reviews

They listened, asked the right questions, and delivered

Jessica Brooks / Co-Founder | Oct 20, 2026

We were very happy with how this project went. 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. 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.

The Web Development work has already made a noticeable difference — tasks that used to take hours now take minutes. We are already discussing the next phase with them.

Project summary

We partnered with Ultraviolet Lab to rebuild a slow, outdated web app and move it to a new framework. Scope included discovery workshops, development in two-week sprints and a short support period after launch. The project took roughly 7 months from kickoff to launch.
