Professional Game Development Team, Smooth Delivery From Start to Finish

Thabo Naidoo / IT Manager | Oct 17, 2026

Tellzer did good work for us, and we would use them again. Their project manager kept things organised and was quick to flag anything that might affect the timeline. They shared working builds regularly, so we could test early and give feedback before things were locked in. The developers were knowledgeable and made a few suggestions that ended up saving us time and money.

We are already seeing better numbers than before the project. Estimates on a few features were optimistic and those took longer than planned. We would definitely work with them again.

Project summary

We engaged Tellzer to develop a casual mobile game from concept to launch. Scope included discovery workshops, development in two-week sprints and a short support period after launch. The project took roughly 9 months from kickoff to launch.

Please describe your company, your role, and the industry you operate in.
I work as IT Manager at Summit Properties (Pty) Ltd. We operate in Real Estate and most of our customers are in and around Cape Town, South Africa.
What specific problem or business challenge led you to hire this company?
Our team was spending too much time on manual work. The goal was to develop a casual mobile game from concept to launch so they could focus on customers.
What services did the company provide for your project?
Mainly Game Development. They also helped with the technical planning and a few integrations with our existing tools.
Why did you choose this company over other providers you considered?
They had relevant experience in Real Estate and their proposal was the clearest of the ones we received.
How clearly did the company understand your requirements and business goals?
They understood our goals quickly, partly because they had worked with Real Estate clients before.

Communication was good overall and improved further once we settled into a routine.
Did the company deliver the project on time and within your expected budget?
It was delivered on time, and the final invoice matched the original estimate.
What tangible results or business impact have you seen since the project was completed?
We can now handle more volume without adding staff, which was the main goal.

Would you recommend this company to others, and would you work with them again?
Yes. They are a reliable Game Development partner.

Honest advice and solid execution

Derek Carter / CEO | Jun 16, 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. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. 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. Documentation at handover was a bit thin and we had to ask for more detail. We are already discussing the next phase with them.

Project summary

Our company worked with Tellzer to build a customer portal where clients can log in, track orders and download invoices. Scope included discovery workshops, development in two-week sprints and a short support period after launch. The engagement ran for about 7 months.

Skilled Cloud Services Team That Understood Our Business

Lena Müller / Senior Engineering Manager | Mar 25, 2026

Overall we had a good experience working with Tellzer. 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. 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.
