Testing Experience: What our clients say about us


End-to-End Testing
“The communication between Telekom, Testbirds and the client development department was very helpful. With the aid of Testbirds we were able to identify and fix bugs as well as gather deep and direct feedback from our customers, which we wouldn’t have found otherwise.”

Michael Gater

Service Launch Manager, Deutsche Telekom

Device Cloud
“Device testing is integral to our mobile QA process at Rebtel. We’ve tried many cloud device testing platforms and none can provide the functionality we need. The GRDN promises to meet our needs and then some, with the globally distributed nature of the network representing real users much better than a single-location device-farm.”

BugAbility™ & Exploratory Bugtests

Corny van de Wal, Team Manager Shop Development & Production
“By crowdtesting on the right devices with the right browser versions and operating systems, Testbirds helps us deliver more customer-friendly websites and keep them customer-friendly (…) We have a continuous process of change, adjustment and improvement. Testbirds offer their testing solutions with the same flexibility and agility, which made us decide to embed their testing services continuously into our development cycle.”

Deutsche Telekom

Test Automation

Alexander Gunnar Kiefer, Technischer Projektleiter, Deutsche Telekom
„Die Zusammenarbeit mit den Entwicklern seitens Testbirds funktioniert sehr unkompliziert und auf hohem fachlichem Niveau. Alle unsere Anforderungen konnten in dem jeweils von uns vorgegebenen Zeitrahmen ohne Verzögerungen und ohne Probleme erfüllt werden“


Comparison Study

David Kane, Director of Editorial Content, VEON
“The results of the A/B comparison UI test for content discovery on VEON had a direct impact on the platform and business and we are grateful for Testbird’s efforts. I wouldn’t hesitate to work with them again.”

Landal GreenParks

Usability and UX Study

Lieven Swinnen, Manager e-Business Landal GreenParks
“Working with Testbirds led to us professionalising our testing process, as it forced us to critically examine our own testing structure. It definitely made our organisation more mature in that respect. Furthermore, crowdtesting has proven to be efficient. We can start testing on a Monday and see the results
on Tuesday. It’s a powerful addition to our development process.”


Training Academy

Isabella Waschak, UX Researcher Testing, metafinanz
„The Testbirds Training Academy was an excellent experience. Our trainer David has explicitly responded to our participants based on their different levels of knowledge. He has succeeded in taking into account all the individual questions and desires, as well as relevant examples and exercises. In this way, we were able to learn about the functions in a practical way, allowing us to already test the first approaches. Testbirds receive the top score for this comprehensive training.“
