Busch Labs/RUF have been an amazing partner for my team and THQ Nordic when it comes to qualitative studies for our video game projects. We were struggling to find partners that were able to adapt to our rapidly changing requirements and short timelines, but Busch Labs continuously went above and beyond our expectations. This is true for recruiting, play sessions, as well as reporting. On top of that, they also helped us strengthen our own internal knowledge and processes when it comes to UX. Marc and his team are very unique, and I strongly recommend them to anybody who has UX-related needs.

Working with Busch Labs on usability research for our mobile inspection solution was extremely valuable. The user testing helped us identify key improvements and simplify the guidance, making the overall experience much more intuitive. We also saw a clear improvement in performance, as users now better understand how to use the solution as intended. Marc was great to work with! Very responsive, flexible to our needs, and able to recruit the right users for our specific use case.

Working with Marc & his team is amazing — he is very client- & human-centric, and makes the impossible happen when it comes to deadlines, finding a panel, supporting the research design, etc. He immersed himself in the topic, and supported our project with outstanding engagement, delivering results on time, with deep, actionable insights.
