Exceeded our expectations on quality and communication

Jess Wright / Founder & CEO | Aug 15, 2026

The project went well overall. 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.

We launched on schedule and have not had any major issues since. Their team changed one developer midway, which slowed things down for a couple of weeks.

If you need a team that communicates well and delivers, they are a good choice.

Project summary

We hired X Stack Inc. to set up a sensor network and alerts for our cold storage facilities. They worked alongside our in-house team, which mostly handled business requirements and testing. The project took roughly 7 months from kickoff to launch.

Skilled AI & Machine Learning Team That Understood Our Business

Amy Lloyd / Co-Founder & CTO | Jun 06, 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. 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.

Feedback from our customers has been very positive so far.

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

Good results, communication improved as the project went on

Emily Doyle / Product Manager | May 14, 2026

We got a good result in the end, but the road there had a few bumps. 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. 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. If you need a team that communicates well and delivers, they are a good choice.

Project summary

Reliable Mobile App Development Partner That Delivered What They Promised

Hannah Shaw / CTO | May 11, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. 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.

A reliable long-term partner for our tech needs

Fatima Al Mansoori / Director of IT | Mar 31, 2026

X Stack Inc. did good work for us, and we would use them again. 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 shared working builds regularly, so we could test early and give feedback before things were locked in.

Feedback from our customers has been very positive so far. A couple of milestones slipped by a week or so, mostly around testing.

We are already discussing the next phase with them.
