Great team to work with — professional, responsive and reliable

Sara Al Mansoori / Senior Product Manager | Sep 28, 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. If you need a team that communicates well and delivers, they are a good choice.

Project summary

We hired Fuellstack to build a customer portal where clients can log in, track orders and download invoices. They also took care of integrations with a couple of third-party tools we already used. Overall it was a 7-month engagement.

Professional team that made a complex project feel manageable

Eric Hayes / Project Manager | Sep 27, 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.

We are already seeing better numbers than before the project. Their team changed one developer midway, which slowed things down for a couple of weeks.

We would definitely work with them again.

Project summary

Our company worked with Fuellstack to add subscriptions and a better checkout to our existing store. Scope included discovery workshops, development in two-week sprints and a short support period after launch. We worked together for around 2 months.

Easy to work with and very transparent on timelines and cost

Carlos Miller / Senior Engineering Manager | Sep 18, 2026

Fuellstack did an excellent job for us. 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. 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 IoT Development work has already made a noticeable difference — tasks that used to take hours now take minutes.

Happy to recommend them.

Project summary

Our company worked with Fuellstack to connect our equipment to a cloud dashboard so we could monitor it remotely. Their team handled planning, development and QA, with our product owner signing off each milestone. We worked together for around 9 months.

Exceeded our expectations on quality and communication

Conor Kelly / Founder & CEO | Sep 08, 2026

We were happy with the final result. They were upfront about what was realistic within our budget, which helped us prioritise the right features. We dealt with the same core team throughout, so we did not have to keep re-explaining things.

The IoT Development 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. Overall, a team we trust and plan to keep working with.

Project summary

Fuellstack was brought in to build firmware and a companion app for a smart device we were launching. Scope included discovery workshops, development in two-week sprints and a short support period after launch. Overall it was a 2-month engagement.

Capable Web Development team — happy with the end result

Dan Reed / Founder & CEO | Sep 04, 2026

Overall the project was a success, though it was not without some challenges. 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 shared working builds regularly, so we could test early and give feedback before things were locked in. Their project manager kept things organised and was quick to flag anything that might affect the timeline.

Feedback from our customers has been very positive so far. 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

We partnered with Fuellstack to build a customer portal where clients can log in, track orders and download invoices. The work covered requirements, design, development, testing and launch support. The engagement ran for about 5 months.

They listened, asked the right questions, and delivered

Emma Sandhu / Owner | Jul 22, 2026

We were very happy with how this project went. We dealt with the same core team throughout, so we did not have to keep re-explaining things. 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.

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

I would recommend Fuellstack to anyone looking for a dependable AI & Machine Learning partner.

Quality work, a little slower than we planned

Yousef Rahman / Director | Feb 25, 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 shared working builds regularly, so we could test early and give feedback before things were locked in.

It has made a real difference to how our team works day to day. Their team changed one developer midway, which slowed things down for a couple of weeks. We would definitely work with them again.

Strong Technical Skills and a Very Responsive Web Development Team

Lauren Brooks / Founder & CEO | Jan 22, 2026

Fuellstack did good work for us, and we would use them again. 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.

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.
