the shift
Why digital accessibility matters in Seattle
The regional economy generated approximately $607.0 billion in Gross Regional Product according to Greater Seattle Partners, reflecting a powerhouse market driven by technology and enterprise commerce. As digital interfaces serve as the primary storefront for millions of consumers and B2B buyers across the Pacific Northwest, maintaining strict WCAG 2.1 and ADA Title III compliance is essential. Organisations must eliminate digital barriers to protect brand equity, avoid costly litigation, and ensure equitable access across high-growth markets.
The Office of Economic Development reported that firms with 100 or more employees drove 74.5% of regional net job growth, placing corporate web properties under heightened scrutiny.
Federal courts recorded 5,062 web accessibility filings in 2025 per OnePageAudit data, highlighting accelerating regulatory enforcement across consumer-facing industries.
Research from TestParty shows remediating code at the source generates upwards of 400% ROI through expanded audience reach and enhanced conversion performance.
our approach
How we approach accessibility in Seattle
We engineer durable compliance by integrating manual assistive technology testing, automated validation, and direct source-code remediation into your digital workflow. Rather than applying superficial overlays that fail legal scrutiny, our engineering team fixes structural code to meet strict WCAG 2.2 AA standards, ensuring full usability across all devices and assistive screen readers.
Codebase Auditing
We conduct thorough automated and manual code audits across desktop and mobile templates. Our technical specialists inspect semantic HTML, ARIA landmarks, colour contrast ratios, and keyboard navigation pathways to pinpoint every barrier violating current WCAG standards.
Manual Screen Testing
Automated tools miss over half of all functional usability issues. Our team conducts hands-on testing with native screen readers, including NVDA, JAWS, and VoiceOver, validating that interactive components operate seamlessly for visually impaired and motor-impaired individuals.
Native Remediation
We resolve accessibility defects directly within your source code and design systems. By correcting DOM hierarchies, focus states, and dynamic elements at the root level, we ensure permanent compliance that survives future content and software updates.
Continuous Governance
Compliance requires constant vigilance as content evolves. We implement continuous monitoring pipelines and regression tests alongside team training, guaranteeing your web applications maintain conformity as new features, landing pages, and assets deploy. cortex

Inside the work
How we approach accessibility in Seattle
Services
Pairing digital accessibility with paid search and performance marketing ensures your paid traffic lands on frictionless, high-converting pages. When ad campaigns direct users to accessible landing pages, bounce rates drop and overall quality scores improve, maximising the return on your paid acquisition spend across the local marketplace.
Integrating accessibility principles with branding and visual design establishes an inclusive identity from the ground up. Our creative team develops accessible colour palettes, readable typography hierarchies, and intuitive component states that elevate aesthetic appeal while maintaining strict contrast and readability standards for every customer.
Connecting accessibility monitoring with web analytics provides clear insight into how diverse user cohorts navigate your digital properties. By tracking keyboard interactions, screen reader drop-offs, and assisted conversions, data teams can pinpoint UX friction and continuously optimise the digital journey for all visitors.
Executing native remediation alongside modern web development ensures clean, resilient code across platforms like Next.js, WordPress, and Shopify. Our developers build accessible component libraries and automated CI/CD compliance testing, keeping web applications compliant across the region during every product release.
