Anysphere (Cursor)

The San Francisco start-up, founded in 2022 by four MIT students, whose AI code editor Cursor, a fork of Microsoft's open-source VS Code with AI built into every part of the editing loop, became the fastest-growing software product of the generative-AI era by its own and investors' accounts. Annualised revenue went from ~$100m (January 2025) to ~$1bn (November 2025) and ~$2bn (February 2026), then a reported ~$3bn (May 2026). All are company or press-reported run rates, not audited figures. Its valuation rose from ~$400m (2024) to $29.3bn (November 2025). For most of its life Cursor resold other companies' models, chiefly Anthropic's Claude, and reports said it ran at a negative gross margin. That dependence drove its later moves: an in-house model line (Composer, from October 2025), a disputed Composer 2 built on Moonshot AI's open Kimi K2.5 (March 2026), and a sale. SpaceX, which by then owned xAI, took an option in April 2026, agreed to buy Cursor in an all-stock deal valued at ~$60bn on 16 June 2026, and closed it on 14 August 2026 (reported). Cursor now operates inside the SpaceXAI group.

Leadership (2026)
Michael Truell (co-founder and CEO; verify title inside SpaceX); Aman Sanger and Sualeh Asif (co-founders); Arvid Lunnemark left in October 2025 to found a safety-focused research lab (reported); Lee Robinson (developer education; formerly Vercel, reported); Travis McPeak (security, from 2025, reported)
AI products
Cursor editor (Tab completion, chat, Agent mode); Bugbot code review (2025); background, web, mobile and cloud agents (2025); Cursor Agent CLI (August 2025); Cursor 2.0 with the Composer model (October 2025); Composer 2 (March 2026); Composer 2.5 and xAI's Grok models in the model picker (2026, reported)
Scale
ARR ~$100m (January 2025); >$500m (June 2025); >$1bn (November 2025); ~$2bn (February 2026, Bloomberg); ~$3bn (May 2026, Bloomberg); ~$4bn (early June 2026, Forbes/Dealroom, reported), of which ~$2.6bn from enterprise/B2B customers (Reuters, company data) — the two figures measure different scopes, not a conflict (re-checked Nov 2026); all company or press-reported run rates. ~300 employees (August 2025, reported)
Capital raised
~$8m seed led by the OpenAI Startup Fund (October 2023); $60m Series A at ~$400m (2024); ~$105m Series B at ~$2.5bn (December 2024/January 2025, reported); $900m Series C at $9.9bn post-money led by Thrive (June 2025); $2.3bn Series D at $29.3bn co-led by Accel and Coatue (13 November 2025); talks for ≥$2bn at ~$50bn pre-money (April 2026, reported, overtaken by the SpaceX deal). About $3.4bn of disclosed funding in all (reported)
Exit
SpaceX option (21 April 2026: buy for $60bn later in 2026 or pay $10bn for joint work); exercised 16 June 2026, all-stock, ~$60bn; closed 14 August 2026, with Anysphere shares converted into SpaceX Class A shares on a seven-day average price; a ~389.3m share count appears only on Wikipedia and implies ~$154 a share, plausible for a seven-day average in the week after the 12 June listing (above the $135 IPO price, below the ~$211 peak) but sourced only to Wikipedia, so treat it as unconfirmed (verify)
Signature moves (incl. failures)
The VS Code fork founding (2022); the Series A and Supermaven (2024); the "Sam" support-bot hallucination (2025); the $9.9bn Series C and revenue ramp (2025); the Pro-plan pricing change and refunds (2025); Cursor 2.0 and the Composer model (2025); the $29.3bn Series D and Graphite (2025); Composer 2 and the Kimi disclosure (2026); the SpaceX option and ~$60bn acquisition (2026)
