Strong Technical Skills and a Very Responsive IT Consulting Team

Dan Price / Managing Director | Oct 11, 2026

I would rate this engagement highly on almost every front. They were upfront about what was realistic within our budget, which helped us prioritise the right features. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

Feedback from our customers has been very positive so far. I would recommend Fonantrix to anyone looking for a dependable IT Consulting partner.

Project summary

We partnered with Fonantrix to help us choose and plan the rollout of a new core system. Scope included discovery workshops, development in two-week sprints and a short support period after launch. The project took roughly 2 months from kickoff to launch.

Reliable Cloud Services Partner That Delivered What They Promised

Sanne de Vries / IT Manager | Aug 15, 2026

Fonantrix did good work for us, and we would use them again. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. They shared working builds regularly, so we could test early and give feedback before things were locked in.

The result looks great and performs well, and our internal team found it easy to take over. Their team changed one developer midway, which slowed things down for a couple of weeks. Happy to recommend them.

Project summary

Fonantrix was brought in to move our application to Azure and set up proper backups and monitoring. The work covered requirements, design, development, testing and launch support. We worked together for around 9 months.

Great team to work with — professional, responsive and reliable

Oliver Walker / VP of Engineering | Jul 21, 2026

Overall we had a good experience working with Fonantrix. They were upfront about what was realistic within our budget, which helped us prioritise the right features. Their project manager kept things organised and was quick to flag anything that might affect the timeline.

The UI/UX Design work has already made a noticeable difference — tasks that used to take hours now take minutes. We had to follow up a few times on smaller bug fixes after launch. We are already discussing the next phase with them.

Project summary

We engaged Fonantrix to redesign the user experience of our SaaS product. They also took care of integrations with a couple of third-party tools we already used. The project took roughly 5 months from kickoff to launch.

Good results, communication improved as the project went on

Oliver Holmes / Program Manager | Jun 30, 2026

The final product works well for us, although the process could have been smoother. 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. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later.

We are already seeing better numbers than before the project. A couple of milestones slipped by a week or so, mostly around testing. We are already discussing the next phase with them.

Project summary

We engaged Fonantrix to build dashboards that pull our sales, marketing and finance data into one place. Scope included discovery workshops, development in two-week sprints and a short support period after launch. The engagement ran for about 3 months.

We were happy with the final result. 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.
