A reliable long-term partner for our tech needs

Maria Morgan / Managing Director | Sep 26, 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. 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.

The Mobile App 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

We hired Delstack to develop a field-staff app with offline mode that syncs back to our main system. The work covered requirements, design, development, testing and launch support. The engagement ran for about 4 months.

Great Experience With Delstack on Our Quality Assurance & Testing Project

Tobias Müller / Program Manager | Sep 08, 2026

Overall we had a good experience working with Delstack. 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 dealt with the same core team throughout, so we did not have to keep re-explaining things.

The Quality Assurance & Testing work has already made a noticeable difference — tasks that used to take hours now take minutes. 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

We engaged Delstack to set up automated testing for our web application. They worked alongside our in-house team, which mostly handled business requirements and testing. The engagement ran for about 4 months.

Great team to work with — professional, responsive and reliable

Nathan Taylor / Head of Digital Transformation | Aug 25, 2026

I would rate this engagement highly on almost every front. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

Professional Mobile App Development Team, Smooth Delivery From Start to Finish

Ahmed Al Nuaimi / Co-Founder & CTO | Jun 22, 2026

We were very happy with how this project went. 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. 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.

It has made a real difference to how our team works day to day.

Happy to recommend them.

Project summary

Our company worked with Delstack to rebuild our existing mobile app, which had poor reviews and frequent crashes. They also took care of integrations with a couple of third-party tools we already used. We worked together for around 8 months.
