SII Belgium Delivered a Quality UI/UX Design Solution on Time

Stephanie Miller / Senior Engineering Manager | Sep 29, 2026

SII Belgium did an excellent job for us. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. They were upfront about what was realistic within our budget, which helped us prioritise the right features.

The UI/UX Design work has already made a noticeable difference — tasks that used to take hours now take minutes. I would recommend SII Belgium to anyone looking for a dependable UI/UX Design partner.

Project summary

SII Belgium was brought in to build a design system so our product looked consistent across screens. The project was split into milestones, with a working build shared at the end of each one. We worked together for around 9 months.

They listened, asked the right questions, and delivered

Rob Barker / CEO | Jul 26, 2026

Overall we had a good experience working with SII Belgium. 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.

The Cloud Services work has already made a noticeable difference — tasks that used to take hours now take minutes. There were some early misunderstandings on requirements that took a few rounds to sort out. Happy to recommend them.

Project summary

We partnered with SII Belgium to reduce our cloud bill and clean up an AWS setup that had grown messy over the years. Scope included discovery workshops, development in two-week sprints and a short support period after launch. The project took roughly 6 months from kickoff to launch.

Ruby Wilson / Founder & CEO | Jul 19, 2026

SII Belgium did good work for us, and we would use them again. They shared working builds regularly, so we could test early and give feedback before things were locked in. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

We launched on schedule and have not had any major issues since. Estimates on a few features were optimistic and those took longer than planned. We are already discussing the next phase with them.

Good work overall, with a few bumps along the way

Raj Leblanc / Managing Director | Jun 27, 2026

The final product works well for us, although the process could have been smoother. We dealt with the same core team throughout, so we did not have to keep re-explaining things. They shared working builds regularly, so we could test early and give feedback before things were locked in.

We launched on schedule and have not had any major issues since. A couple of milestones slipped by a week or so, mostly around testing. If you need a team that communicates well and delivers, they are a good choice.

Skilled IoT Development Team That Understood Our Business

Megan Fisher / Co-Founder & CTO | May 17, 2026

I would rate this engagement highly on almost every front. Their project manager kept things organised and was quick to flag anything that might affect the timeline. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building.

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.

Great team to work with — professional, responsive and reliable

Ahmed Saleh / Engineering Manager | Apr 18, 2026

Overall we had a good experience working with SII Belgium. We dealt with the same core team throughout, so we did not have to keep re-explaining things. 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.

It has made a real difference to how our team works day to day. Estimates on a few features were optimistic and those took longer than planned.

We would definitely work with them again.
