What Sourdline does
Sourdline is a France-based B2B accessibility platform that enables deaf and hard-of-hearing individuals to access customer service from enterprises, retailers, and government organizations. Founded in 2004 and headquartered in Colombes, with a second operational site in Reims, the company operates as a private SASU led by President Caroline Mitanne.
The platform combines three communication modalities: (1) webcam-based real-time interpretation in French Sign Language (LSF) and Cued Speech (LPC) by certified deaf and hearing interpreters; (2) live chat with real-time speech-to-text transcription (Transcription Instantanée de la Parole) and text-to-speech conversion (Chat Auto); and (3) direct video advice from trained deaf and bilingual counselors. The service is delivered through white-labeled partner subdomains (e.g., matmut.sourdline.com, coriolis.sourdline.com), an iOS mobile application, and an underlying video/chat infrastructure provided by Nubitalk. Conversation recording is used for quality assurance with opt-out available, and all personal data is stored in Europe in compliance with GDPR.
Sourdline generates revenue through B2B subscription contracts with partner brands, with 53+ named enterprise and government clients across retail, luxury, telecom, insurance, automotive, energy, food, travel, media, and municipal services. Marquee clients include Louis Vuitton, Renault, TotalEnergies, Galeries Lafayette, Bouygues Telecom, Matmut, Sephora, and several French municipalities. The company also markets to the deaf community directly through community events, deaf associations (Miss & Mister France Sourd, Deaf Cup Europa), and social channels. Operational scale indicators include 35,000 calls handled annually, 8,900+ active users ("liners"), and 11-50 employees. Sourdline is a founding member of the Fédération Française Accessibilité (FFA) and maintains institutional relationships with BPI France, SITELGroup, and adapted-enterprise networks (GESAT, UNEA).
