Skilled AI & Machine Learning Team That Understood Our Business

Eric Carter / Co-Founder | Sep 01, 2026

Quellcode 360 GmbH did an excellent job for us. They shared working builds regularly, so we could test early and give feedback before things were locked in. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. We dealt with the same core team throughout, so we did not have to keep re-explaining things.

Since launch, everything has been stable and our team has adapted to it quickly. Overall, a team we trust and plan to keep working with.

Project summary

We partnered with Quellcode 360 GmbH to add an AI chatbot to our support site that answers questions from our help docs. Their team handled planning, development and QA, with our product owner signing off each milestone. We worked together for around 5 months.

Great Experience With Quellcode 360 GmbH on Our Web Development Project

Rahul Sharma / IT Manager | Aug 04, 2026

Quellcode 360 GmbH did an excellent job for us. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. They were upfront about what was realistic within our budget, which helped us prioritise the right features.

The result looks great and performs well, and our internal team found it easy to take over. We would definitely work with them again.

Great Experience With Quellcode 360 GmbH on Our Mobile App Development Project

Jessica Bennett / Director | Jul 31, 2026

I would rate this engagement highly on almost every front. 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. If you need a team that communicates well and delivers, they are a good choice.

Project summary

We hired Quellcode 360 GmbH to rebuild our existing mobile app, which had poor reviews and frequent crashes. Scope included discovery workshops, development in two-week sprints and a short support period after launch. Overall it was a 7-month engagement.

Delivered on time and stayed involved after launch

Charlotte Edwards / Senior Product Manager | Jul 05, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. 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. They shared working builds regularly, so we could test early and give feedback before things were locked in.

The result looks great and performs well, and our internal team found it easy to take over.

I would recommend Quellcode 360 GmbH to anyone looking for a dependable Mobile App Development partner.

Project summary

Our company worked with Quellcode 360 GmbH to build iOS and Android apps for our customers, including booking, payments and push notifications. The project was split into milestones, with a working build shared at the end of each one. Overall it was a 9-month engagement.

Great team to work with — professional, responsive and reliable

Jason Graham / IT Director | Jun 08, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. 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. They shared working builds regularly, so we could test early and give feedback before things were locked in. Their project manager kept things organised and was quick to flag anything that might affect the timeline.

Since launch, everything has been stable and our team has adapted to it quickly. We are already discussing the next phase with them.

Professional team that made a complex project feel manageable

Lotte de Vries / IT Director | May 16, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later.

Solid delivery, though timelines needed some pushing

Stephanie Sullivan / Managing Director | Feb 04, 2026

Overall the project was a success, though it was not without some challenges. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later.
