Most things these days are instant and on-demand, except the money you're working hardest for. At EarnIn, we’re reimagining the way money moves to empower every person’s potential.

The EarnIn app can help you make the most of your money, stay on track, and build progress day-by-day.

Kodiak was founded in 2018 to redefine long-haul trucking using safe and reliable autonomous technology. Between growing e-commerce and a strong economy, demand for trucking is on the rise. The trucking industry faces major problems: a shortage of drivers, difficult working conditions, and extremely high turnover. According to the American Trucking Association, the industry faced a shortage of 51,000 commercial truck drivers at the end of 2017. Long-haul trucking is primed for autonomous technology. Highway driving is more structured and predictable than urban driving. This means there are fewer decisions for drivers to make and a better fit for autonomous vehicles. We believe that autonomous trucks will play a major role in filling the gap while improving safety, enhancing truck driver quality of life, increasing efficiency, reducing congestion and emissions and creating jobs across the economy.

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.
