What Tanaguru does
Tanaguru SAS is a Paris-based digital accessibility services and open-source tooling company founded in 2009, operating as a privately held société par actions simplifiée with share capital of €20,000 and a team of 11–50 employees. The company serves French public administrations and private enterprises required to comply with RGAA (and international WCAG) accessibility standards, delivering professional services including accessibility audits, advisory, training, process industrialization, and end-to-end accessible website development.
Its core product, Tanaguru Engine, is an open-source (AGPL3) web accessibility testing tool hosted on GitLab that automates approximately 380 checks across RGAA, AccessiWeb, and WCAG. The engine uses Firefox instances to analyze rendered source code and CSS, crawler4j for site-wide crawling (up to 10,000 pages), and Selenium for scenario audits of JavaScript and AJAX applications, with an exposed REST API and four audit modes (page, site, scenario, offline file). Complementary open-source assets include Tanaguru Contrast-Finder, the Contrast Switcher, and the bilingual RGAA reference website (rgaa.tanaguru.com).
Tanaguru's revenue is generated primarily from professional services delivered through direct sales to French administrations and enterprises (with named clients including Société Générale, CNED, Fondation Valentin Haüy, Kering, Pôle Emploi, and the Ministry of Culture), supplemented by structured training programs sold through formations.tanaguru.com. A free SaaS demo at my.tanaguru.com and self-hosted open-source distribution provide product-led top-of-funnel reach, though commercial pricing is not publicly disclosed and growth is funded organically with no external investment evidenced.
