Cursor

Cursor is an AI-first code editor built by Anysphere, a San Francisco startup founded in 2022 by four MIT graduates. Originally a fork of Visual Studio Code, Cursor has evolved into a full agent-based development platform where autonomous AI handles everything from autocomplete to end-to-end feature building. With $2B+ in annualised revenue, over half the Fortune 500 as customers, and a valuation that reached $29.3B after its Series D in November 2025, Cursor has become the fastest-growing SaaS company ever from $1M to $500M ARR - turning the IDE from a code-writing tool into an AI orchestration layer.
