Cursor

Cursor is an AI-first code editor built for pair programming with large language models. Founded in 2022 by Michael Truell and teammates from MIT, Cursor has grown to become the most popular AI coding tool among professional developers. The editor is built on top of VS Code and integrates Claude and GPT-4 deeply into the coding workflow, allowing developers to write, edit, and understand code with natural language. Cursor reached $100 million in annual recurring revenue with just 50 employees, making it one of the fastest growing developer tools in history. The company raised $60 million in Series B funding at a $2.5 billion valuation from investors including Andreessen Horowitz and Benchmark. Cursor is used by over 500,000 developers worldwide including engineers at top technology companies. The product is particularly popular for large codebase navigation, refactoring, and generating boilerplate code.
