Cursor

Market-leading AI IDE with $2B in annual revenue

Cursor is the AI coding IDE developed by Anysphere, a startup founded in 2022 in San Francisco, which has become in 2026 the fastest-growing B2B SaaS company in history: zero to $2 billion ARR in roughly three years (ahead of Slack, Zoom and Snowflake). As of February 2026, Cursor counts over 1 million paying customers, 2 million total users, 1 million DAU and is used by 70% of the Fortune 1,000. The Series D funding round in November 2025 set the valuation at $29.3 billion, and Bloomberg reported in April 2026 ongoing discussions for a new round at a $50 billion valuation. The tool is a VS Code fork entirely rebuilt around AI, with 100% native compatibility for existing extensions, keybindings and themes. The product is structured around several pillars: Composer 2 (released March 19, 2026), proprietary MoE model optimized for long-horizon agentic coding with 200K token context, beating Claude Opus 4.6 on Terminal-Bench 2.0 (61.7 vs 58.0) at one-tenth the per-token price; Background Agents to run parallel tasks while the developer works on something else; Bugbot for automated code review; Supermaven autocomplete (2024 acquisition), the fastest autocomplete on the market; and multi-model access to GPT-5.5, Claude Opus 4.7, Gemini 3.1 Pro, xAI Grok and proprietary Cursor models. .cursorrules files let teams standardize generated code per project or per organization. The offering breaks down into six plans: Hobby (free, limited completions and Agent requests), Pro at $20/month (unlimited Tab autocomplete, extended Agent requests, frontier model access, monthly credits equal to subscription cost), Pro+ at $60/month (3× Pro credits), Ultra at $200/month (20× Pro plan usage, priority access to new features), Teams at $40/user/month (centralized billing, SSO, admin controls) and Enterprise custom-priced (pooled usage, dedicated support, SOC 2 Type 2 compliance). The billing model has been credit-based since June 2025: each plan provides a pool equal to its subscription cost, consumed depending on the model used — Auto mode automatically routes to the most cost-effective model to extend credit lifetime. Cursor today targets three audiences: professional developers who code daily in VS Code and want the most mature, best-supported IDE+AI experience (Pro at $20/month remains the individual sweet spot), engineering teams with heavy agentic usage for whom Composer 2 changes session unit economics, and Fortune 1000 organizations standardized on Cursor for deployments across thousands of seats (the Salesforce example with 20,000 engineers and >90% internal adoption is a reference). Cursor nonetheless remains marked by two points deserving vigilance: the controversial usage-based pricing since June 2025, which has transformed the tool into infrastructure cost rather than SaaS subscription for intensive teams, and the fact that Composer 2 is built roughly 25% on Kimi K2.5, the Chinese open-source model from Moonshot AI — confirmed by Cursor on March 20, 2026 but rarely highlighted.
