Anysphere

Anysphere, Inc. is an American software company which offers Cursor, an AI-assisted software development service. Founded in 2022, the San Francisco-based startup achieved a US$29.3 billion valuation and surpassed US$1 billion in annual recurring revenue by late 2025. Cursor is commonly described as a vibe coding app.

The company was incorporated in 2022 by Michael Truell, Sualeh Asif, Arvid Lunnemark and Aman Sanger while they were students at Massachusetts Institute of Technology (MIT). In October 2023 the startup announced an US$8 million seed round led by the OpenAI Startup Fund, with angels including former GitHub CEO Nat Friedman and Dropbox co-founder Arash Ferdowsi.

In November 2024 TechCrunch reported that Benchmark, Index Ventures and others were bidding up Anysphere's valuation to about US$2.5 billion, four months after a US$60 million Series A that had valued the company at US$400 million.

In March 2025 the company was reported to be negotiating a round that would value it near US$10 billion. On 5 June 2025, Anysphere confirmed a US$900 million Series C led by Thrive Capital, lifting its post-money valuation to US$9.9 billion.

Anysphere crossed US$100 million in annual recurring revenue (ARR) in January 2025, and topped US$500 million ARR by June 2025.

In April 2025, an AI help-desk program named "Sam" invented a non-existent login policy, triggering user cancellations before staff intervened and issued refunds.

In October 2025, co-founder and Chief Technology Officer Arvid Lunnemark left the company to found a safety-focused AI research lab, Integrous Research.

On 13 November 2025, Anysphere closed a US$2.3 billion Series D funding round co-led by Accel and Coatue Management, valuing the company at US$29.3 billion. The round included participation from strategic partners Google and Nvidia. Following this round, the company reported its annualized revenue had exceeded US$1 billion.

In April 2025, Anysphere was featured in the Forbes AI 50 list.

In early 2026, Bloomberg and The Information reported that Anysphere was in discussions to raise approximately US$5 billion at a valuation of between US$50 billion and US$60 billion, which would roughly double the Series D valuation within four months.

In April 21, 2026, xAI announced that it struck a deal with Anysphere to have the right to acquire the company for $60 billion later this year, or to pay $10 billion for work they are doing together.

Cursor is a fork of Visual Studio Code that integrates AI-assisted software development capabilities directly into the editor.

A July 2025 change to Cursor's US$20 Pro plan, switching from 500 requests to a usage-metered cap, provoked complaints about unexpected charges; the firm rolled back limits and promised refunds.

The editor integrates generative models from Anthropic, OpenAI and others. In July 2025, Anysphere launched “Bugbot”, a debugging tool integrated with GitHub and sold as an add-on for $40 per user per month.

In November 2024, Anysphere acquired Supermaven, an AI code-completion startup founded by Jacob Jackson, for an undisclosed sum. The Supermaven team was folded into Cursor, and Supermaven's standalone product was wound down in late 2025.

In July 2025, Anysphere acquired top engineering talent from Koala, an AI-powered customer relationship management startup, to staff a new enterprise-readiness team; Cursor did not adopt Koala's CRM product, and Koala subsequently shut down. Around the same time, Anysphere hired Travis McPeak, co-founder and CEO of cybersecurity startup Resourcely, to lead its security team.

In December 2025, Anysphere agreed to acquire Graphite, a New York-based code-review startup, in a cash-and-equity deal reported to be well above Graphite's most recent US$290 million valuation.

Anysphere prohibits the use of AI tools during the first round of coding interviews and invites finalists for a two-day on-site project with the core team. As of August 2025, the company employs roughly 150 people.

In April 2025, an AI help-desk agent named “Sam” invented a non-existent login policy, prompting user cancellations before staff apologized and issued refunds. A July 2025 change to Cursor’s Pro plan pricing drew complaints about unexpected charges; the company apologized, rolled back limits, and said it would refund affected users.
