Good value and a team that genuinely cares about the result

Brandon Sullivan / Founder | Sep 03, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. 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. If you need a team that communicates well and delivers, they are a good choice.

Project summary

We partnered with ZS to containerize our application and move it to Kubernetes. The work covered requirements, design, development, testing and launch support. We worked together for around 6 months.

Dependable IoT Development Partner for a Growing Nonprofit & NGO Business

Julia Hoffmann / Director | Aug 18, 2026

I would rate this engagement highly on almost every front. 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 were upfront about what was realistic within our budget, which helped us prioritise the right features.

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

Happy to recommend them.

Honest advice and solid execution

Ella Thompson / Chief Digital Officer | Jul 09, 2026

We were very happy with how this project went. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later.

Feedback from our customers has been very positive so far.

Happy to recommend them.

Good work overall, with a few bumps along the way

Rob Edwards / Founder & CEO | Jun 25, 2026

Overall the project was a success, though it was not without some challenges. 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 team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later.

It has made a real difference to how our team works day to day. Documentation at handover was a bit thin and we had to ask for more detail. I would recommend ZS to anyone looking for a dependable AI & Machine Learning partner.

Reliable Quality Assurance & Testing Partner That Delivered What They Promised

Amanda Price / Co-Founder | May 18, 2026

Overall we had a good experience working with ZS. We dealt with the same core team throughout, so we did not have to keep re-explaining things. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. They were upfront about what was realistic within our budget, which helped us prioritise the right features.

Feedback from our customers has been very positive so far. Their team changed one developer midway, which slowed things down for a couple of weeks.

Capable IoT Development team — happy with the end result

Saud Al Harbi / Director | Mar 08, 2026

We got a good result in the end, but the road there had a few bumps. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. 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.

Since launch, everything has been stable and our team has adapted to it quickly. Their team changed one developer midway, which slowed things down for a couple of weeks. Happy to recommend them.
