Fluency, Inc.

Fluency, Inc. is an edtech company founded in 2017 and headquartered in Curitiba, Brazil. Its Fluency Academy is an online language school that teaches practical communication skills through AI-powered conversation practice, live tutor classes and recorded lessons. The company describes itself as the largest language school in Latin America, with more than 450,000 students, and offers seven languages: English, Spanish, French, German, Italian, Japanese and Korean.

The technical work at Fluency sits in artificial intelligence applied to language learning. Central to the platform is an AI avatar conversation practice product, in which students speak with AI avatars rather than work through grammar drills. The company also builds speech and conversation practice technology and the broader online learning platform that supports its teaching model. The pedagogical approach was shaped by a founder story rooted in dissatisfaction with traditional memorisation-based methods; the emphasis is on speaking confidence from the first lesson.

Alongside its consumer offering, Fluency sells corporate language training (B2B) to companies upskilling their teams. The business serves individual learners and corporate clients across Latin America and, through its online delivery, globally. The company's stated mission is to democratise language learning and make it accessible to everyone.
