Deque and Eficode partner to embed automated accessibility into AI-powered development pipelines across Denmark, Finland, Norway and Sweden.

Deque and Eficode partner to embed automated accessibility into AI-powered development pipelines across Denmark, Finland, Norway and Sweden. May 13, 2026 New forces are reshaping the global digital accessibility landscape. Most notably, the European Accessibility Act (EAA) has now been in effect for a year, and Deque Systems, Inc has already seen far-reaching regulatory and legal developments as a result. Simultaneously, AI coding assistants continue to use inaccessible content to generate even more content, leading to rapidly swelling volumes of inaccessible code. In this time of great opportunity and equally great challenge, Deque and Eficode are announcing a strategic partnership to provide a practical, low-friction path to EAA compliance that does not require slowing down delivery or rebuilding workflows. "This new era of digital accessibility demands an approach that combines the speed and scale of AI with human expertise. Eficode has the highest number of IAAP CPWA-certified professionals of any organization in the European Economic Area and supports its customers across the full software and service lifecycle. This is a natural and impactful partnership, and we're excited to bring our collective expertise to new and existing Deque and Eficode customers." - Preety Kumar, CEO and founder, Deque Achieving digital accessibility compliance in the EAA era is a complex effort that requires collaboration among stakeholders across many teams and disciplines, including Chief Technology Officers and Engineering VPs, DevOps leads, compliance officers, and digital accessibility leads. Through this new partnership, organizations can achieve sustainable accessibility at scale by combining Eficode's user-centered design and DevOps expertise with Deque's innovative accessibility technology. By embedding automated, AI-powered accessibility testing into continuous integration and continuous delivery (CI/CD) pipelines - and embracing a shift-left approach where testing is performed earlier in the design and development process - organizations can catch up to 80% of defects before production. As a leading global provider of DevOps, AI-driven software development, and human-centered design services, Eficode combines modern technology, strong DevOps practices, and deep expertise in accessibility and user experience. Deque, meanwhile, is recognized by leading industry analysts for its AI-powered tools, comprehensive services, and developer-trusted solutions, and for delivering the industry's most complete accessibility offering. "By combining Deque's industry-leading accessibility tools with Eficode's highly skilled experts, we help organizations shift from reactive fixes to proactive prevention, and from mere compliance to genuinely inclusive digital experiences, embedding accessibility from design through continuous delivery." - Jussi Rämänen, Head of UX - Research, Design & Accessibility, Eficode Together with Deque, Eficode is helping DevOps teams at companies across Denmark, Finland, Norway, and Sweden implement accessibility testing technology to ensure they meet the needs of their audiences, the goals of their businesses, and the relevant global regulatory requirements. An essential component of how Deque advances its mission of digital equality is its global network of trusted partners, each committed to delivering the highest standards of digital accessibility excellence. Thanks to its new partnership with Eficode, Deque Systems, Inc is better positioned than ever to support not only existing Eficode and Deque customers but any organization across the EU that wants to reduce EAA compliance risk and lower the cost of accessibility remediation while maintaining delivery velocity. As global digital accessibility continues to evolve rapidly, disruptions will persist - including the very real legal risks posed by inaccessible, AI-generated code. The best way to ensure your organization stays ahead is to work with trusted, innovative leaders who can help you credibly demonstrate to regulators, customers, and stakeholders that accessibility is built into your software delivery process by design. Deque Systems, Inc is inviting every organization that needs to achieve EAA compliance, including all current Eficode customers, to reach out to Deque today for strategic digital accessibility guidance.

Strategic partnership with Deque to make accessibility part of everyday team workflows.

Strategic partnership with Deque to make accessibility part of everyday team workflows. Accessibility should not be treated as a one-off fix, but as part of the process and everyday team workflows. This is the context behind the collaboration TOTHOMweb has been building with Deque for some time now. As a leading company in digital accessibility with an internationally recognised track record, Deque enables TOTHOMweb to integrate its tools into the workflows of teams developing digital products. When accessibility is part of the process. Implementing accessibility is not usually a question of willingness. In most cases, the challenge is when and how it is introduced into the process. When accessibility is built in from the start and becomes part of everyday workflows, it stops being seen as a barrier and starts to fit naturally into the design, development and maintenance of digital products. By contrast, when it is left until the end, delays, rushed adjustments and the feeling that "this creates more problems than it solves" start to appear. The difference is not about intention, but about approach, timing, and having the tools and support needed to work on accessibility on an ongoing basis. At TOTHOMweb, TOTHOMweb has been working for some time to help teams integrate accessibility naturally into their way of working and into the decisions made throughout a project. How this collaboration came about. Deque has launched a partnership programme in Europe and invited TOTHOMweb to join it as a company specialising in digital accessibility. For TOTHOMweb, Deque is a reference point because of its work in automating the detection of barriers in complex environments, its track record with large organisations, and its experience in implementing solutions and certification processes in the United States. This collaboration gives TOTHOMweb access to tools and to the support of an experienced team, helping TOTHOMweb implement accessibility more systematically across different teams while maintaining its own approach and way of working. Tools to better support teams. Over the past 25 years, Deque has developed a well-established set of tools that help teams work more effectively. These tools make it possible to detect errors before they reach production, monitor issues over time and reduce the time between a problem appearing and being fixed. When they are well integrated into day-to-day work, they help prevent recurring issues and improve efficiency. Advanced automated accessibility tools make it possible to increase speed, coverage and scalability in the detection of barriers, especially in large-scale and recurring reviews. Even so, a significant number of accessibility issues still require manual validation and expert judgement, since identifying them depends on context, interpretation and real user experience. That is why combining automated, semi-automated and manual testing makes it possible to achieve more complete coverage, improving speed and scalability without losing technical judgement or human review. For teams that want to make accessibility part of their everyday work, using tools such as Deque's together with support from experienced professionals can be a strong starting point for moving forward with confidence. A step in line with the way TOTHOMweb work. This collaboration fits with the path TOTHOMweb were already on. It allows TOTHOMweb to strengthen the support TOTHOMweb provide to teams, improve follow-up and rely on tools that fit the way TOTHOMweb work. TOTHOMweb is continuing to do what TOTHOMweb has done so far, but with a greater ability to detect issues earlier, support teams better and reduce unnecessary friction on the way to more accessible digital products.
