Stellum Reviews

Great team to work with — professional, responsive and reliable

Conor Walsh / Founder | Aug 19, 2026

Stellum did good work for us, and we would use them again. 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. 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. There were some early misunderstandings on requirements that took a few rounds to sort out. We would definitely work with them again.

Project summary

We partnered with Stellum to port our game to new platforms and improve performance. The work covered requirements, design, development, testing and launch support. The engagement ran for about 7 months.

We're a mid-sized Pharmaceuticals & Biotechnology company based in Cork, Ireland. I'm the Founder and I oversaw the project from start to finish.

Communication was good overall and improved further once we settled into a routine.

Yes. They are a reliable Game Development partner.

Delivered on time and stayed involved after launch

Ashley Brooks / Owner | Aug 03, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. 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. 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 Software Development work has already made a noticeable difference — tasks that used to take hours now take minutes. We are already discussing the next phase with them.

Project summary

Stellum was brought in to develop a scheduling and dispatch tool for our field team. They also took care of integrations with a couple of third-party tools we already used. The engagement ran for about 2 months.

Quality work, a little slower than we planned

Owen Roy / Operations Manager | Jul 24, 2026

Overall the project was a success, though it was not without some challenges. They shared working builds regularly, so we could test early and give feedback before things were locked in. They were upfront about what was realistic within our budget, which helped us prioritise the right features.

Since launch, everything has been stable and our team has adapted to it quickly. Documentation at handover was a bit thin and we had to ask for more detail. We would definitely work with them again.

Project summary

We partnered with Stellum to automate document data extraction that our team was doing by hand. Their team handled planning, development and QA, with our product owner signing off each milestone. We worked together for around 9 months.

Would happily work with them again

Lachlan Murphy / Project Manager | Jul 13, 2026

The project went well overall. 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. They shared working builds regularly, so we could test early and give feedback before things were locked in.

The result looks great and performs well, and our internal team found it easy to take over. 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

Our company worked with Stellum to rebuild our existing mobile app, which had poor reviews and frequent crashes. Scope included discovery workshops, development in two-week sprints and a short support period after launch. The engagement ran for about 6 months.

Professional team that made a complex project feel manageable

Darren Tan / CEO | Jun 30, 2026

Overall we had a good experience working with Stellum. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. 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. Documentation at handover was a bit thin and we had to ask for more detail.

I would recommend Stellum to anyone looking for a dependable IoT Development partner.

Project summary

We partnered with Stellum to connect our equipment to a cloud dashboard so we could monitor it remotely. The project was split into milestones, with a working build shared at the end of each one. Overall it was a 7-month engagement.

A reliable long-term partner for our tech needs

Marcus Tan / Co-Founder | Jun 29, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. Their project manager kept things organised and was quick to flag anything that might affect the timeline. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. 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. I would recommend Stellum to anyone looking for a dependable Software Development partner.

Project summary

Stellum was brought in 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. The engagement ran for about 8 months.
