Cursor

Anysphere was founded in 2022 by Michael Truell, Sualeh Asif, Aman Sanger, and Arvid Lunnemark while they were students at MIT [3]; Forbes later characterized them as "4 MIT Dropouts In Their 20s" [13]. The company initially built mechanical engineering tools for automating CAD, then pivoted to automating code after identifying a larger opportunity aligned with the team's expertise [4]. Rather than shipping a plugin, the team built a full IDE, along with custom AI models for tasks such as autocomplete, designed to complement foundation models like GPT [4].

The company raised an $8 million seed round in October 2023 led by the OpenAI Startup Fund, with angels including former GitHub CEO Nat Friedman and Dropbox co-founder Arash Ferdowsi [3]. A $60 million Series A at a $400 million valuation followed in August 2024 [3][7]. In November 2024, Anysphere acquired Supermaven, an AI code-completion startup founded by Jacob Jackson; the team was folded in and the standalone product wound down in late 2025 [3]. The company crossed $100 million in recurring revenue in January 2025 [3] and announced a $105 million Series B at a $2.5 billion valuation from Thrive Capital, Andreessen Horowitz, and Benchmark [7][15]. In early 2025, Anysphere was approached by OpenAI and other potential buyers and turned down those offers; OpenAI instead purchased Windsurf, reportedly for $3 billion [10][14].

On June 5, 2025, the company confirmed a $900 million Series C at a $9.9 billion post-money valuation, led by Thrive Capital with participation from Andreessen Horowitz, Accel, and DST Global [3][10]; it surpassed $500 million ARR the same month [10]. July 2025 brought the launch of the Bugbot code-review tool, the acquisition of engineering talent from the CRM startup Koala, and the hiring of Travis McPeak to lead the security team [3]. In October 2025 the company released Cursor 2.0 and announced its Composer model [3][6]; co-founder Lunnemark departed that month to found Integrous Research, a safety-focused AI research lab [3].

On November 13, 2025, Anysphere closed a $2.3 billion Series D at a $29.3 billion post-money valuation, co-led by Accel and Coatue Management, with NVIDIA and Google named as new investors [3][8][11], and crossed $1 billion in annualized revenue [8]. Following the round, all four cofounders, then in their twenties, were billionaires, per Forbes [13]. In December 2025 the company agreed to acquire Graphite, a New York code-review startup, in a cash-and-equity deal reported well above Graphite's most recent $290 million valuation [3]. In early 2026 it was reportedly in discussions to raise roughly $5 billion at a $50–60 billion valuation [3], and it surpassed $3 billion ARR by May 2026, per Bloomberg [3].

On April 21, 2026, SpaceX announced a deal giving it the right to acquire Cursor for $60 billion later in the year, or to pay $10 billion for joint work [3]. On June 16, 2026, SpaceX announced it would acquire Anysphere in an all-stock transaction valuing Cursor at $60 billion, placing it under the SpaceXAI subsidiary with closing expected in Q3 2026 [3][16]. Reuters corroborated the valuation and timing [16]; the finer deal mechanics derive from the company's Wikipedia article, which carries a banner warning it may include unverified claims [3].

Cursor searches codebases, edits files, runs terminal commands, and carries out multi-step programming tasks from natural-language instructions [3]; its tagline is "Turn ideas into code" [2]. The application runs on Windows, macOS, iOS, and iPadOS [3], and agents have been released for web, mobile, command-line, and cloud environments [3]. Cursor 2.0, released in October 2025, runs multiple agents in parallel using git worktrees or remote machines [3]. Product features include subagents that explore a codebase in parallel, Instant Grep search across millions of files, team rules encoding conventions, Plan, Design, and Debug lifecycle modes, sandboxed terminal commands, git checkpoints with rollback, and extensibility through community plugins, Skills, and MCP integrations [2]. Design Mode, launched June 5, 2026, lets users point, draw, or narrate UI changes in the browser while agents edit the underlying code [2]. Bugbot, launched July 2025, runs automated review on GitHub pull requests [3][9].

Cursor integrates third-party models from Anthropic and OpenAI alongside its own coding models [3]. Composer, announced October 29, 2025, is a mixture-of-experts model specialized for software engineering through reinforcement learning in development environments; on Cursor's benchmarks it achieves frontier coding results with generation speed four times faster than similar models [6]. The Composer 2 technical report, published March 26, 2026, describes a model built on the Kimi K2.5 base (1.04 trillion parameters, 32 billion active), trained in MXFP8 on NVIDIA B300 GPUs, scoring 61.3 on CursorBench, 61.7 on Terminal-Bench, and 73.7 on SWE-bench Multilingual [5]. Grok 4.5, released July 8, 2026 and listed as a joint product with SpaceXAI, was described as "our most intelligent model and the first we've built for more than software engineering" [2][3][6].

Enterprise plans add administrative controls, usage analytics, single sign-on, and model controls [3], with zero data retention, SOC 2 Type 2 certification, AES-256 encryption at rest, and TLS 1.2+ in transit; no on-premises deployment is offered [9].

Cursor sells tiered subscriptions after a two-week free trial: a $20-per-month Pro plan and a $40-per-month Business plan [10]. Historically, the majority of revenue came from individual subscriptions; the company later added enterprise licenses combining seat-based and consumption-based pricing [10][14][9]. Its enterprise page states that 64% of Fortune 500 companies use Cursor, that more than 50,000 enterprises build with it, and that over 100 million lines of enterprise code are written with it per day [9]. Named customers include Stripe, NVIDIA, Coinbase, Salesforce, PayPal, Rippling, Brex, and Datadog [2][9]; NVIDIA CEO Jensen Huang has said, "My favorite enterprise AI service is Cursor" [9].

Recurring revenue exceeded $100 million in January 2025 [3][7], reached $300 million ARR by mid-April 2025 [10], surpassed $500 million in June 2025 [10], crossed $1 billion annualized in November 2025 [8], and surpassed $3 billion ARR by May 2026 [3]. A person familiar with the company said in June 2025 that ARR was doubling approximately every two months [10]. Headcount was reported at roughly 150 in August 2025 [14] and "over 300" by November 2025 [8]; as of August 2025 the company held around $1 billion in cash reserves with single-digit monthly burn [14]. Michael Truell serves as CEO, Sualeh Asif as Chief Product Officer, and Jordan Topoleski as Chief Operating Officer [3]. The company prohibits AI tools during first-round coding interviews and invites finalists for a two-day on-site project [3].

Anthropic is simultaneously a deep dependency and, per Newcomer, Cursor's "fiercest competitor" [14]. OpenAI is a seed investor that once tried to buy the company and later acquired the competitor Windsurf [10][14]. Truell has said the market for AI coding tools is "much larger than people realize," that one dominant winner is likely, and that defensibility comes from continuous product innovation and "consumer-like moats" rather than enterprise lock-in [4].

In April 2025, an AI support agent named "Sam" invented a non-existent login policy, triggering user cancellations; staff intervened, apologized, and issued refunds [3]. In July 2025, a change to the Pro plan that replaced 500 monthly requests with a usage-metered cap drew complaints about unexpected charges; the company apologized, rolled back the limits, and promised refunds [3]. Reporting from August 2025 described negative gross margins, driven in part by heavy compute bills paid to Anthropic for a subset of high-usage individual subscribers, and noted venture-capital debate over whether rapid growth masks rough unit economics and Anthropic reliance [14]. Forbes reported in March 2026 that the company "is confronting a new reality: developers may no longer need a code editor at all" [12].
