Cursor, the AI-native code editor developed by Anysphere, has achieved a remarkable milestone by reaching $300 million in Annual Recurring Revenue (ARR) within just 21 months of its launch. This rapid growth positions Cursor as the fastest-growing SaaS company in history, surpassing competitors like Wiz, Deel, and Ramp in terms of ARR acceleration. The company’s success is attributed to its product-led growth strategy and a freemium model that has attracted a vast user base of individual developers. 

Cursor’s core functionality revolves around providing an AI-powered integrated development environment (IDE) that assists developers in writing, editing, and automating coding tasks. Unlike traditional code editors that later incorporated AI features, Cursor was designed from the ground up to be AI-native, integrating advanced models like GPT-4 and Claude to enhance developer productivity. This approach allows developers to describe their coding intentions in plain English, with the AI generating, explaining, and refining the code accordingly.
