Capable UI/UX Design team — happy with the end result

Emily Lloyd / Founder | Oct 13, 2026

We got a good result in the end, but the road there had a few bumps. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. The developers were knowledgeable and made a few suggestions that ended up saving us time and money.

We launched on schedule and have not had any major issues since. Their team changed one developer midway, which slowed things down for a couple of weeks.

If you need a team that communicates well and delivers, they are a good choice.

Project summary

We partnered with Cortesys to build a design system so our product looked consistent across screens. Scope included discovery workshops, development in two-week sprints and a short support period after launch. We worked together for around 6 months.

Cortesys Delivered a Quality Web Development Solution on Time

James Lloyd / Head of Product | Aug 19, 2026

I would rate this engagement highly on almost every front. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. 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. Happy to recommend them.

Overall the project was a success, though it was not without some challenges. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. The developers were knowledgeable and made a few suggestions that ended up saving us time and money.

Solid IT Consulting Work With Clear Communication Throughout

Pieter Botha / Founder | Jul 02, 2026

I would rate this engagement highly on almost every front. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. We dealt with the same core team throughout, so we did not have to keep re-explaining things. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later.

The result looks great and performs well, and our internal team found it easy to take over. Overall, a team we trust and plan to keep working with.

Dependable Mobile App Development Partner for a Growing Mining & Metals Business

Thabo van der Merwe / Owner | Mar 19, 2026

We were happy with the final result. They shared working builds regularly, so we could test early and give feedback before things were locked in. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. The developers were knowledgeable and made a few suggestions that ended up saving us time and money.

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. I would recommend Cortesys to anyone looking for a dependable Mobile App Development partner.

Skilled IoT Development Team That Understood Our Business

Amy Harding / Director | Mar 14, 2026

The project went well overall. 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. Even with the time zone difference, responses usually came the same day and we never felt left in the dark.

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. Happy to recommend them.

Carlos Coleman / Founder & CEO | Feb 24, 2026

Honestly, this was one of the smoothest projects we have run with an outside team.

Quality work, a little slower than we planned

Noah Wilson / Co-Founder & CTO | Feb 23, 2026

We got a good result in the end, but the road there had a few bumps. We dealt with the same core team throughout, so we did not have to keep re-explaining things. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building.

The UI/UX Design work has already made a noticeable difference — tasks that used to take hours now take minutes. Documentation at handover was a bit thin and we had to ask for more detail.

If you need a team that communicates well and delivers, they are a good choice.

Project summary

Cortesys was brought in to run user research and create new designs for our mobile app. They also took care of integrations with a couple of third-party tools we already used. The engagement ran for about 3 months.
