On June 5, 2025, Anysphere, the company behind the AI code editor Cursor, confirmed a $900 million funding round at a $9.9 billion valuation. Bloomberg first reported the round, with TechCrunch and SiliconANGLE confirming the same day. Three years after founding, the startup had turned AI coding from a developer niche into the hottest ticket in the capital markets.
For scale: $900 million raised and a $9.9 billion valuation would be a big story in any year for a software startup. In 2025, it read as the first genuine mega-revenue story of the AI application layer — not a model company, but a company wrapping models into a productivity tool and selling it.
The round and the valuation
Per TechCrunch and SiliconANGLE, the round was led by returning investor Thrive Capital, with participation from Andreessen Horowitz, Accel, and DST Global. It was Anysphere’s third fundraise in three years of existence — and the third in under a year: the previous round was $100 million at a $2.5 billion pre-money valuation in December 2024, which TechCrunch was first to report. In under six months, the valuation nearly quadrupled. Per Bloomberg, investors called Anysphere the fastest-growing software startup of all time.
The growth numbers: ARR and pricing
The valuation rests on the revenue curve. Bloomberg reported that Anysphere’s annualized recurring revenue had passed $500 million — up about 60% from the $300 million TechCrunch reported in mid-April — and a person familiar with the company told TechCrunch that ARR was doubling roughly every two months. That pace is close to unheard of in software history.
The pricing structure matters too. Cursor offers a two-week free trial, then converts users to paid: a $20-per-month Pro plan or a $40-per-month business subscription. Bloomberg noted that until recently the majority of revenue came from individual subscriptions; Anysphere now sells enterprise licenses that let companies buy the app for teams at a higher price point. For any SaaS company, moving from individual subscriptions to enterprise contracts usually means bigger deals and longer retention — key context for the valuation jump. Put differently: a $9.9 billion valuation against $500 million of ARR is roughly a 20x multiple on annualized revenue. That is not cheap for any software company, but with revenue doubling every two months, investors were buying the next few quarters, not the current income statement.
Three rounds in a year and buyout approaches
Two other pieces of background matter here. First, cadence: three rounds inside a year is nearly impossible in a traditional venture cycle, and it only happens when revenue is exploding. Second, buyer interest. TechCrunch reported that earlier in the year, OpenAI and other potential buyers approached Anysphere and were turned down; OpenAI then bought Windsurf, another fast-growing AI coding assistant, reportedly for $3 billion. Major model companies scrambling to add coding tools to their portfolios only confirmed the strategic value of the category.
What it means for the developer-tools market
For developers and the tools market, the round settled a few things. One: AI coding was the first application category of the LLM era to produce large-scale paying demand — TechCrunch called it one of AI’s most popular applications, with Cursor leading the category. Two: entry-point value. Whoever owns the developer’s editor owns the channel through which model capability becomes productivity, which is exactly why model companies were willing to pay for acquisitions. Three: business-model validation. Twenty- and forty-dollar monthly plans proved developers will pay directly for efficiency, without waiting on corporate procurement. Four: the competitive picture. When model companies start buying editors outright — the Windsurf deal was the signal — the endgame question for independent tools lands on the table; Anysphere chose to refuse acquisition and raise independently, leaving that question to the market.
A snapshot of the vibe-coding boom
TechCrunch’s report noted that tools like Cursor are often referred to as “vibe coders”: developers describe what they want in natural language, and the AI generates most of the code. The category had become one of AI’s most popular applications, with Cursor as its flagship product. Unlike earlier autocomplete-style assistants, Cursor embeds model capability directly into the editor and the whole development loop, turning “AI writes code” from an assist into the mainline workflow. The round functioned as a public pricing event for the category: developer tools were not just one use case for AI, but its fastest-compounding revenue channel at the time.
Looking back, Anysphere’s valuation and round sizes kept climbing after this point — but the June 2025 round was the first time the market priced it as the leading company of the AI application layer: $900 million raised, a $9.9 billion valuation, and a revenue curve doubling every two months.
