Anysphere

Overview

Anysphere is the company behind Cursor, the AI native code editor that has become the most popular AI coding tool in the world. Founded in 2022 by Michael Truell, Sualeh Asif, Arvid Lunnemark, and Aman Sanger, all MIT graduates, Anysphere is headquartered in San Francisco. The company's sole product is Cursor, a VS Code fork that integrates AI deeply into every aspect of the coding experience: autocomplete, inline editing, chat, autonomous agent mode, codebase indexing, and multi file editing. Cursor has grown explosively, reaching over $1 billion in annualized recurring revenue by late 2025, making it one of the fastest growing software companies in history. Anysphere has raised over $3.2 billion in total funding. The Series C round in June 2025 raised $900 million at a $9 billion valuation led by Thrive Capital, a16z, and Accel. The Series D in November 2025 raised $2.3 billion at a $29.3 billion valuation. Over 50% of Fortune 500 companies use Cursor, and the team has grown to over 300 people. The company's thesis is that AI will fundamentally change how software is written, and that an AI native editor (built from the ground up around AI capabilities) will outperform AI features bolted onto existing editors. Cursor supports multiple LLM providers (Claude, GPT, Gemini, and others) and lets users bring their own API keys.

What makes them different

Anysphere took the approach of building an AI native editor rather than an AI plugin. By forking VS Code and rebuilding the editing experience around AI, Cursor can do things that extensions cannot: predictive edits across multiple files, deep codebase indexing that informs every suggestion, agent mode that autonomously implements features, and a tab completion system that understands not just the current file but the entire project context. The growth trajectory is unprecedented for a developer tool. Going from zero to $1 billion ARR in roughly two years, with a $29.3 billion valuation, puts Anysphere in rare company. The company has attracted top AI talent and engineering talent, and the pace of feature development is extremely fast. Compared to GitHub Copilot (the incumbent AI coding tool), Cursor offers a more integrated experience with deeper AI capabilities. Copilot is an extension that adds suggestions to your existing editor; Cursor is a full editor where AI is woven into every interaction. Compared to Claude Code (the terminal based agent), Cursor offers a visual editor experience while Claude Code offers deeper autonomous capabilities in the terminal. Anysphere is model agnostic. While many AI tools are tied to a single model provider, Cursor works with Claude, GPT, Gemini, and other models, letting users choose the best model for their needs or bring their own API keys for cost optimization.
