Discover how our holistic design approach, intersecting inclusivity and accessibility standards, can take you further in accessibility compliance by exploring all possible routes, including outside of digital.
Boost your solution’s accessibility
Designing for accessibility often improves usability for all users, such as clearer navigation, better color contrast, and more intuitive interfaces.
Cater your solutions to more users
By designing accessible digital solutions, you expand your potential user base, leading to better SEO, happier users and increased revenue opportunities.
Reach the highest compliance levels
Achieving AA or AAA on WCAG 2.1 or WCAG 3.0 guidelines helps meeting legal and regulatory requirements and demonstrates your commitment to accessibility.
What we can do for you
Accessibility audit
Know to what degree your digital product or landscape is compliant with accessibility guidelines, and get a clear view what areas can be improved. We help you on the road to an audit that is bespoke to your needs, and will cover design and/or code. Outcomes are covered in a presentation that can serve as input for your accessibility improvements.
Accessible design & Inclusive design
From setting up a design library to development handover, we safeguard accessibility for your product. Our designers are matched with extensive knowledge on inclusive design and accessibility, and are capable to design to meet accessibility guidelines (e.g. WCAG 2.1 or 3.0).
Learn how we reached level AA for CoronaCheck and AAA for the Dutch Ministry.
Accessibility validation
We help you validating how different inclusion groups can use your current product or new designs. The conclusions of the usability testing is covered in a presentation and can serve as input for future iterations.
Accessible design training
Does your design or product team lack knowledge on designing for accessibility? We can give a bespoke 1 or 2 day training to boost knowledge and make impact.
Reach out to discuss the needs of your team. We like to think along.
