It all started with this: what if we could help make the lives of people with disabilities better. Many companies offer ramps, wider isles, talking ATMs, accessible washrooms or automatic doors. But we saw a widening gap between the physical and digital world for people with disabilities.

Our digital accessibility solution then became the catalyst in helping educate purpose-driven organizations on the benefits of enhancing the customer experience for people with disabilities. We were soon able to form a global coalition of private and public sector organizations, who came together to make digital platforms welcoming to people of all abilities and to ensure the delivery of a transformational experience with universal appeal.
We didn’t stop there. We worked closely with organizations like the ANA (Association of National Advertisers) and inaugurated the People with Disabilities category in their annual Multicultural Excellence Award. Winners in the category include brands such as Duracell, Kimberley Clark, and Jockey.

We are headquartered in Toronto, Canada, and have offices in the United States and Brazil.

Our team is made up of a bunch of people crazy enough to believe that web accessibility is more than just good coding, it’s also giving people with disabilities a suite of tools for them to navigate the web.
