What our customers say

Testimonial Symbol

"Working with Pan Friebe from the first moment was a total success. He took our still very vague ideas, understood them, and transformed them into something tangible - and much better than we had imagined. What we particularly like: He thinks along, speaks clearly about what works and what doesn't, and brings his own impulses in. It doesn't feel like a “service”, but like real cooperation. We are very happy to continue working with him - and are really happy that we found him through Malt."

Ralf-Marco, Avataro GmbH

Testimonial Symbol

"Till has been a solid addition to the BlazeSQL team since May 2025. He's made several meaningful improvements to our Flutter app. He introduced a modern Riverpod-based architecture with repository patterns, which improved our codebase structure. He also set up continuous integration and expanded our test coverage, making releases more reliable. On the feature side, Till developed the Workspace feature that simplifies database access management, built 'Train Blaze' so users can teach our AI directly, and added custom functions that let users teach the AI their own commands. Till communicates well, writes clean code, and delivers consistently. The app has progressed steadily since he joined."

Justus, BlazeSQL

"Super friendly and helpful software agency! Till Friebe and his team developed for me an easy-to-use, individual CRM system for my dog school, exactly tailored to my needs. I never would have thought that I could save so much time that I can now completely dedicate my free days to something else instead of preparing the bookkeeping. The collaboration was very cooperative, quick, and reliable. I experienced the process on eye level and totally uncomplicated. I am really happy with the result and can absolutely recommend FriebeDev! Especially for self-employed and small businesses looking for a digital solution!"

Testimonial Symbol

"The FriebeDev team developed the new get2 app for us. What impressed us most during the project was the transparent communication: everything just flowed by itself, without us having to put in a lot of energy. Even after the release, FriebeDev was always quickly reachable, implemented direct adjustments, and even supported us in managing the app. A real added value was the introduction of new AI tools that allowed us to optimize and streamline our processes. Already after one month after the release, our rating in the iOS store noticeably improved. We are completely satisfied with the results and can highly recommend FriebeDev."
