Solid Software Development Work With Clear Communication Throughout

Khalid Fernandes / Managing Director | Sep 01, 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. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. 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.

We would definitely work with them again.

Project summary

We hired Overtartup GmbH to build a custom operations platform to replace the spreadsheets and email threads we were running the business on. The work covered requirements, design, development, testing and launch support. Overall it was a 2-month engagement.

How was your overall experience with their communication and project management?
Very responsive. We usually heard back the same day, even with the time difference.

Yes. They are a reliable Software Development partner.

Easy to work with and very transparent on timelines and cost

Nora Al Otaibi / Owner | Aug 20, 2026

Our experience with Overtartup GmbH 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. They were upfront about what was realistic within our budget, which helped us prioritise the right features.

We launched on schedule and have not had any major issues since.

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