About the Project & Team It evolved into a developer-loved toolkit with hundreds of active users, 7,000 weekly CLI runs, 5,000 GitHub stars, and over 100 million translated words. We've graduated from the world's best tech accelerator (Y Combinator) and raised venture funding to continue building developer tools that must exist but don't yet. We're a small, fully remote team of senior engineers who like to work hard on interesting problems. We value computer science craft over corporate politics and love building tools for developers
- including ourselves. As part of a team of senior engineers, design, develop, and grow the Lingo.
