  • Our mission is to reinvent the way people learn, starting with language.

The result is a complete path from beginner to confident speaker across multiple languages.

Speak is one of the world's leading AI companies, with over $150m raised in venture investment from OpenAI, Accel, Founders Fund, Khosla Ventures, and more, with a distributed team across San Francisco, Seoul, Tokyo, Taipei, and Ljubljana.
