About Clarantium

An independent firm specialising in digital accessibility audit and compliance. RGAA 4, WCAG 2.1 AA, EAA.

Our approach

Clarantium was born from a simple observation: digital accessibility has become a legal obligation, but available solutions are either ineffective automatic overlays or generalist firms without deep technical expertise. We bridge law, UX and code.

Who we are

A digital accessibility expert, certified on the RGAA 4 framework, with dual expertise in web development and compliance auditing. Based in Bordeaux, France, operating across Europe.

Our standards

We apply the full RGAA 4 framework — 106 criteria. Our audits also cover WCAG 2.1 level AA, the international reference standard, and prepare your compliance with the European Accessibility Act (EAA).
