What Aditus does
Aditus is a privately held web accessibility company founded in 2019 and headquartered in the Porto/Matosinhos area of Portugal. The firm helps organizations make their websites and digital products accessible and compliant with WCAG 2.1, Section 508, and ADA, primarily serving companies without in-house accessibility expertise as well as compliance-focused and development teams. Its offering combines an upcoming SaaS monitoring platform (currently on a waitlist) with a free Button Contrast Checker tool and a suite of professional services, including a three-phase Accessibility Audit (Assessment, Improvement, Compliance) that produces a VPAT 2.3, an Accessibility Statement, and an Aditus Certificate, plus tailored consulting, free 45-minute consultations, and training.
Underlying technology is centered on automated and semi-automated web accessibility scanning using established open-source engines such as axe-core, pa11y, and Total11y, supplemented by manual functional testing; the firm itself states automated testing covers only about 30% of accessibility issues. The platform is intended to deliver continuous monitoring, impact analysis, and actionable fix recommendations for developers, designers, writers, and managers.
Aditus operates a hybrid go-to-market: a product-led growth motion via the free Button Contrast Checker (with email waitlist capture) at the top of the funnel, and a sales-led motion for enterprise clients routed through free consultations into paid audits and training on a quote-based, multi-year contract basis. The company is bootstrapped with no disclosed institutional funding, operates with a small team of roughly 1-10 (two principals publicly identified: founder Liliana Medeiros Guerra and João Figueiredo), and supports customer acquisition through content marketing, social channels, and community/developer-relations activity.
