When OpenAI launched its frontier AI fashions, the trade discourse rapidly shifted to AI ‘consuming’ startups, significantly SaaS firms. Regardless of these considerations, one of many startups to have thrived in an AI-first panorama was Cursor.
In keeping with analysis from Sacra, the AI-enabled coding platform reached $100 million in annual recurring income (ARR) inside 21 months of its inception. It took Cursor solely 12 months to achieve this determine from $1 million ARR, making it the fastest-growing SaaS firm of all time. The report added that Cursor reached these figures with roughly 360,000 particular person builders who paid $20 – $40 month-to-month.
Anysphere, its dad or mum firm, was based in 2022 by MIT college students and pals Michael Truell, Sualeg Asif, Arvid Lunnemark, and Aman Sanger. Their imaginative and prescient was to construct an built-in growth surroundings (IDE) that was “AI native”, and so they launched Cursor in January 2023 on prime of Microsoft’s Visible Studio Code.
Founders ‘Obsessive about the Drawback of Higher AI Coding’
Cursor started with the ambition to take over the competitors. Whereas Microsoft had launched a GitHub Copilot software for AI-assisted coding in 2021, Cursor wished to distinguish itself by integrating the newest out there AI fashions, offering a superior person expertise, and frequently implementing new options and capabilities.
In September 2023, the corporate raised an preliminary $8 million in funding from OpenAI’s startup fund. In August 2024, Anysphere raised $60 million funding in Collection A from Andreessen Horowitz (a16z), Thrive Capital, and different buyers.
“Our perception is that Cursor, distinctly amongst AI coding instruments, has merely gotten it proper,” stated a16z in a weblog publish. “They [Cursor’s founders] are obsessive about the issue of higher AI coding, and are laser-focused on constructing an awesome developer expertise,” the VC agency added.
The corporate additionally not too long ago raised $105 million in Collection B funding led by Thrive Capital, a16z, and different current buyers.
A big win for Anysphere was that its customers became Cursor evangelists very quickly. The product was predominantly geared toward particular person builders, in contrast to conventional SaaS makers that prioritised enterprise gross sales. Cursor additionally provided a free tier to check out the platform, moreover a $20/month Professional subscription and $40/month/person for Enterprise.
Moreover particular person customers, AI specialists, like former OpenAI researcher Andrej Karpathy, have been vocal about their love for Cursor.
Cursor was additionally clear on understanding all the issues with current AI-enabled coding options, and the group, on a number of events, printed a complete record of issues it meant to unravel.
Initially, Cursor functioned as an AI-powered autocomplete software. Nevertheless, its capabilities rapidly expanded to incorporate extra autonomous options able to dealing with complicated coding issues with the launch of Composer, an AI agent mode. Moreover, builders may chat with the code database, retrieve real-time info from the net, and use AI fashions to grasp the code base.
Ultimately, the platform obtained forward of the competitors.
Cursor additionally positions itself as an extension of the human engineer, however to not merely change one. “Utilizing a mix of AI and human ingenuity, they [the hybrid engineers] will out-smart and out-engineer one of the best pure-AI system,” the corporate claims. This technique resonated with customers, who most well-liked Cursor’s workflow over Devin’s (an end-to-end autonomous software program growth software).
Evaluating it to Devin, Will Brown, an AI researcher at Morgan Stanley, stated on X, “I feel I barely favor the ‘pair programming’ workflow of Cursor agent, which is far more hands-on. You’re reviewing the code in real-time, plus [you] can provide ideas extra simply.”
Will Cursor Stay Undefeated?
This isn’t to say Cursor is free from competitors. Microsoft’s GitHub Copilot is estimated to earn greater than $300 million in income yearly. Sacra additionally famous that GitHub Copilot has an “huge benefit”, due to its tight-knit integration in Microsoft’s ecosystem, in addition to its current enterprise relationships and safety compliances.
Different instruments like Vercel’s v0, Bolt.new, and Coedium’s Windsurf competed immediately towards Cursor. Carl Rannaberg, a software program engineer, said in his overview that Cursor “stays the go-to software for day-to-day coding duties” due to its acquainted code editor surroundings. Alternatively, v0 excels in speedy interface prototyping, and Bolt.new “shines in full stack prototyping and fast mission setups”.
Nevertheless, Coedium’s Windsurf has emerged as the largest menace to Cursor. Not too long ago, a number of builders have been reportedly transitioning to Windsurf.
“Windsurf outperforms Cursor when working inside an current large-scale codebase. Cursor struggles to keep up context as tasks develop,” stated Corey Sutton, an engineer in a weblog publish evaluating each platforms. He additionally stated that Windsurf was higher at managing API modifications, whereas Cursor struggles to keep up consistency in TypeScript-heavy environments.
On the finish of 2024, Sacra estimates Codeium to have earned $12 million in income.
Moreover standalone merchandise, Cursor additionally faces competitors from frontier mannequin makers. Not too long ago, Anthriopic launched its coding agent, the Claude Code. A developer on Reddit in contrast the 2, and stated that the code high quality of Claude Code “blows Cursor out of the water”.
As revealed by the founders in a podcast episode with Lex Fridman, Cursor faces important challenges associated to each infrastructure and mannequin administration. As utilization grows, system parts like caching and databases encounter sudden points.
Cursor processes code within the cloud, however it should additionally keep in sync with the native surroundings. “One of many technical challenges is all the time ensuring that the native index, and the native code base state is identical because the state that’s on the server,” stated Sualeh.
Nevertheless, Cursor has grown exponentially over the previous few months. The founders additionally stated that the ceiling is ‘extremely’ excessive for innovation and that Cursor’s benefit comes not simply from integrating newer fashions but in addition from the depth at which it’s built-in into the software. “You don’t realise [how the AI models] are working for you in each aspect of the product, in addition to the actually considerate UX with each single function,” stated Sanger.
