Get AI-powered advice on this job and more exclusive features.
About Speak Our mission is to reinvent the way people learn, starting with language. Learning a language can change a life by opening doors to new cultures, careers, and communities. Two billion people around the world are actively trying to learn a language, but the best way to learn (one‑on‑one tutoring) is hard to access at scale and hasn’t been meaningfully improved in decades. Speak is building a human‑level, AI‑powered tutor in your pocket: a conversation‑first experience that lets learners actually speak, get instant feedback, and progress through carefully designed lessons. The result is a complete path from beginner to confident speaker across multiple languages. Speak first launched in South Korea in 2019 and now serves learners in many markets across 15+ languages. We are a leading AI company with over $150m raised from OpenAI, Accel, Founders Fund, and Khosla Ventures, with a distributed team in San Francisco, Seoul, Tokyo, Taipei, and Ljubljana.
