Skilled UI/UX Design Team That Understood Our Business

Lena Schmidt / Founder & CEO | Oct 10, 2026

The project went well overall. 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. Estimates on a few features were optimistic and those took longer than planned. If you need a team that communicates well and delivers, they are a good choice.

Project summary

Our company worked with Sunztech Intl to redesign the user experience of our SaaS product. They worked alongside our in-house team, which mostly handled business requirements and testing. The project took roughly 9 months from kickoff to launch.

Great team to work with — professional, responsive and reliable

Kevin Price / IT Director | Sep 26, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. Even with the time zone difference, responses usually came the same day and we never felt left in the dark.

Feedback from our customers has been very positive so far. Overall, a team we trust and plan to keep working with.

Project summary

We engaged Sunztech Intl to build a custom operations platform to replace the spreadsheets and email threads we were running the business on. They also took care of integrations with a couple of third-party tools we already used. Overall it was a 5-month engagement.

They listened, asked the right questions, and delivered

Sanne Jansen / Director of IT | Jul 14, 2026

The project went well overall. Their project manager kept things organised and was quick to flag anything that might affect the timeline. We dealt with the same core team throughout, so we did not have to keep re-explaining things.

Feedback from our customers has been very positive so far. Documentation at handover was a bit thin and we had to ask for more detail. We would definitely work with them again.

Raj Leblanc / CEO | Jul 02, 2026
