Accessibility testing with users who rely on assistive technology.
The Problem
You want your product to be accessible. Not just compliant, but genuinely usable for people with disabilities.
WCAG audits catch code issues, not usability problems. A product can pass every automated check and still be unusable for someone navigating with a screen reader. Real accessibility means testing with people who use assistive technologies daily. Automated checkers miss real usability issues. WCAG compliance does not mean a screen reader user can actually complete tasks. You need to test with real users, not just audit code.
The Solution
We recruit participants who use assistive technologies daily. Screen readers, voice control, switch devices, magnification. Real users testing real tasks, revealing issues automated tools cannot find.
Accessibility insights from the people who matter most. Issues prioritized by real-world impact, not just compliance.
Sessions with blind, low-vision, motor-impaired, and neurodiverse users who rely on assistive tech daily.
Observe actual NVDA, JAWS, and VoiceOver users navigate your product. Discover what automated tools miss.
Testing with voice control, switch devices, eye-tracking, and keyboard-only navigation.
Sessions with neurodiverse users to evaluate clarity, cognitive load, and error recovery.
We source participants with specific disabilities and assistive tech expertise from our accessibility panel.
Watch real sessions: screen readers, magnifiers, alternative inputs. See actual friction points.
Detailed findings organized by user group, severity, and fix complexity.
Actionable roadmap: quick wins, high-impact fixes, and long-term improvements.

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.
