Delivered on time and stayed involved after launch

Fatima Al Mansoori / Owner | Sep 17, 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. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. Even with the time zone difference, responses usually came the same day and we never felt left in the dark.

The IoT 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

Our company worked with Stakk 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. The engagement ran for about 8 months.

Solid delivery, though timelines needed some pushing

Vikram Menon / Founder | May 16, 2026

The final product works well for us, although the process could have been smoother. 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.

It has made a real difference to how our team works day to day. There were some early misunderstandings on requirements that took a few rounds to sort out.

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

Project summary

We hired Stakk to build a supply chain traceability prototype on a permissioned blockchain. Scope included discovery workshops, development in two-week sprints and a short support period after launch. We worked together for around 2 months.

Good results, communication improved as the project went on

Joanne Tan / CEO | May 16, 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. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

The result looks great and performs well, and our internal team found it easy to take over. There were some early misunderstandings on requirements that took a few rounds to sort out. I would recommend Stakk to anyone looking for a dependable Mobile App Development partner.

Stakk did good work for us, and we would use them again. The developers were knowledgeable and made a few suggestions that ended up saving us time and money.
