Honest advice and solid execution

Chris Carter / CEO | Oct 20, 2026

Our experience with GSM Marketing LLC was really positive from start to finish. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. Even with the time zone difference, responses usually came the same day and we never felt left in the dark.

We are already seeing better numbers than before the project.

Happy to recommend them.

Project summary

We hired GSM Marketing LLC to build iOS and Android apps for our customers, including booking, payments and push notifications. The work covered requirements, design, development, testing and launch support. Overall it was a 3-month engagement.

They listened, asked the right questions, and delivered

Thabo Naidoo / Chief Digital Officer | Sep 22, 2026

Our experience with GSM Marketing LLC was really positive from start to finish. We dealt with the same core team throughout, so we did not have to keep re-explaining things. 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.

The DevOps Services work has already made a noticeable difference — tasks that used to take hours now take minutes.

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

Dependable Software Development Partner for a Growing Nonprofit & NGO Business

Andre Brooks / Director of Technology | May 26, 2026

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

It has made a real difference to how our team works day to day. We are already discussing the next phase with them.

Would happily work with them again

Noura Saleh / Owner | Feb 18, 2026

The project went well overall. Their project manager kept things organised and was quick to flag anything that might affect the timeline. We dealt with the same core team throughout, so we did not have to keep re-explaining things. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later.

We are already seeing better numbers than before the project. Documentation at handover was a bit thin and we had to ask for more detail. Happy to recommend them.
