Cursor

Cursor is an AI coding tool and agent for software development, made by Anysphere, Inc. of San Francisco, California. It edits files, runs terminal commands and handles multi-step tasks.

Anysphere was founded in 2022 by Michael Truell, Sualeh Asif, Aman Sanger and Arvid Lunnemark, who were MIT students when they incorporated it; Lunnemark left in October 2025. Cursor 2.0 (October 2025) added parallel agents and its own Composer model. Composer 2 (March 2026) was built on Moonshot AI's open-weights Kimi 2.5, which was not disclosed at launch until users found it. Aman Sanger called leaving it out of the blog a miss. Anysphere also makes the Bugbot code-review tool and bought Supermaven in 2024.

By the time of the Grok Build story of 11 November 2026, Cursor was no longer independent. SpaceX signed a $10 billion partnership with an option to buy it in April 2026, exercised the option on 16 June, and closed the $60 billion all-stock purchase of Anysphere on 14 August 2026, with the team joining SpaceXAI (since renamed SpaceXSI). Grok 4.6 became available inside Cursor and Grok Build around the close. Press reported that Cursor probed whether staff leaked client data to SpaceX before the deal; the coverage found no public evidence of exposure.
