About us

TestingTime is a Swiss start-up which recruits test users for user and market research. The name TestingTime originates from the traditional English “tea time” – time for the light snack regularly enjoyed in the late afternoon. While the Swiss are not accustomed to “tea time”, we were inspired by its light and regular nature and transferred this to the world of user research.

“It’s TestingTime!” – that’s our daily call to thousands of test users to take part in exciting user tests, interviews, focus groups or online surveys. UBS, Zalando, SBB, Trivago and many more have already discovered the true requirements of their (potential) customers. User satisfaction is noticeably increased through improved products and services, and competitiveness on the market is enhanced.

TestingTime started as a part-time project, but it quickly gained popularity, resulting in the foundation of the company TestingTime AG in early 2015. In August 2015, the commitment was sealed with an impressive financing round through investiere.ch. We are driving the realisation of our vision of unlimited access to any target group with zeal and unconditional dedication.
