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, where Speak has now become the number one language learning app, and we now serve learners across many markets and 15+ 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.

CROSSK is building Whitebrinjal — an AI-driven decision infrastructure for complex enterprise technology procurement. Enterprises struggle to evaluate emerging technologies because the hardest work happens before procurement: defining the problem, aligning stakeholders, comparing unfamiliar solutions, validating fit, and building the business case. Whitebrinjal structures this fragmented pre-procurement journey into a decision layer—helping enterprises move from complex problems to decision-ready engagement with the right technology providers, while helping providers reach qualified enterprise opportunities with context, intent, and stakeholder alignment. We are solving the gap between “we have a complex problem” and “we know what to buy, why, and from whom.”
