Dependable IoT Development Partner for a Growing Insurance Business

Rachel Bennett / Managing Director | Sep 26, 2026

Our experience with STELLIS was really positive from start to finish. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. They shared working builds regularly, so we could test early and give feedback before things were locked in.

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

Project summary

We partnered with STELLIS to set up a sensor network and alerts for our cold storage facilities. The project was split into milestones, with a working build shared at the end of each one. We worked together for around 8 months.

Good work overall, with a few bumps along the way

Ella Walker / Director | Sep 13, 2026

Overall the project was a success, though it was not without some challenges. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. 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. Estimates on a few features were optimistic and those took longer than planned. We are already discussing the next phase with them.

Project summary

We partnered with STELLIS to provide ongoing monitoring and support for our cloud infrastructure. They also took care of integrations with a couple of third-party tools we already used. The engagement ran for about 5 months.

Solid Web Development Work With Clear Communication Throughout

Fatima Qureshi / CTO | Aug 26, 2026

We were very happy with how this project went. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. Their project manager kept things organised and was quick to flag anything that might affect the timeline. They were upfront about what was realistic within our budget, which helped us prioritise the right features.

We are already seeing better numbers than before the project. We would definitely work with them again.

Project summary

Reliable IoT Development Partner That Delivered What They Promised

Lotte Bakker / Engineering Manager | Jun 30, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. 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. The developers were knowledgeable and made a few suggestions that ended up saving us time and money.

Feedback from our customers has been very positive so far.

Happy to recommend them.

Easy to work with and very transparent on timelines and cost

The project went well overall. They were upfront about what was realistic within our budget, which helped us prioritise the right features. 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.
