dotSource SE Delivered a Quality Cloud Services Solution on Time

Ella Thompson / Senior Engineering Manager | Sep 26, 2026

Our experience with dotSource SE 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. Their project manager kept things organised and was quick to flag anything that might affect the timeline.

We launched on schedule and have not had any major issues since. We are already discussing the next phase with them.

Project summary

Our company worked with dotSource SE to move our application to Azure and set up proper backups and monitoring. Scope included discovery workshops, development in two-week sprints and a short support period after launch. We worked together for around 3 months.

Great team to work with — professional, responsive and reliable

Sean Kelly / Co-Founder | Jul 24, 2026

Overall we had a good experience working with dotSource SE. 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.

We launched on schedule and have not had any major issues since. Documentation at handover was a bit thin and we had to ask for more detail. We would definitely work with them again.

Project summary

dotSource SE was brought in to rebuild our existing mobile app, which had poor reviews and frequent crashes. The project was split into milestones, with a working build shared at the end of each one. We worked together for around 3 months.
