About
Speak was founded in 2016 in San Francisco with the mission of eliminating the speaking barrier in language learning — the gap between understanding a language academically and being able to use it fluently in real conversation. The company built an AI language tutor that creates immersive, voice-first practice environments allowing learners to speak freely without the anxiety of a human judge, with AI providing immediate pronunciation feedback, correction, and contextual follow-up questions.\n\nSpeak's app focuses on conversational output rather than passive input, using speech recognition and AI conversation models to simulate real interactions across structured lesson tracks, open-ended speaking practice, and grammar explanation. Its curriculum is designed around natural usage patterns rather than textbook sequences, with particular depth in English learning for Korean, Japanese, and other Asian language markets. Speak is backed by OpenAI, reflecting a strategic alignment with frontier language model development that gives the company early access to AI capabilities that power its tutoring engine.\n\nSpeak achieved a $1B unicorn valuation and $100M in revenue, making it one of the most commercially successful AI-native language learning products globally. The company raised $162M in total funding and has seen particularly strong growth in Asia, where demand for English fluency in professional contexts drives high willingness-to-pay. Speak competes with Duolingo on consumer mindshare but differentiates fundamentally by prioritizing speaking practice — the dimension of language acquisition that traditional apps have historically struggled to deliver.
