Great team to work with — professional, responsive and reliable

Ashley Hayes / Director of Technology | Oct 20, 2026

Zonalgo did an excellent job for us. They shared working builds regularly, so we could test early and give feedback before things were locked in. 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.

The Web Development work has already made a noticeable difference — tasks that used to take hours now take minutes.

We would definitely work with them again.

Project summary

Zonalgo 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. We worked together for around 3 months.

Dependable E-commerce Development Partner for a Growing Gaming & Gambling Business

Eric Graham / Owner | Sep 06, 2026

Our experience with Zonalgo was really positive from start to finish. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. 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.

Feedback from our customers has been very positive so far. If you need a team that communicates well and delivers, they are a good choice.

Project summary

We hired Zonalgo to build a Shopify store with custom features for our product range. Their team handled planning, development and QA, with our product owner signing off each milestone. We worked together for around 8 months.
