AI-based code editor Cursor's maker, Anysphere has acquired AI-based coding assistant Supermaven for an undisclosed amount.

The acquisition was announced in a blog posting on Cursor by Anysphere CEO Michael Truell. The acquisition allows Anysphere to introduce a newer version of its Tab AI model, which is "fast, context-aware and highly intelligent," he said, especially at sequences of long code.

Truell said that Supermaven's plugins will remain supported, but Cursor will be the core focus going forward.

"This is roughly the same as the old Supermaven plan: the team had shifted focus to an editor because extension APIs were blocking the next useful things that they wanted to build," wrote Truell in his post. "Why join forces? We have a lot to do, and it seems like we can build a more useful product, faster, together."

Superrmaven is founded by Jacob Jackson, former co-founder of the AI coding assistant known as Tabnine. Jackson had sold his Tabnine to Codata in 2019 before joining OpenAI as an intern in 2022.

Another AI coding platform is Supermaven-but like Tabnine, it has a quality of life and technical upgrades. Their in-house generative AI model is called Babble, said to be able to understand a lot of code at once and with an architecture that's extremely low-latency.

By September, more than 35,000 developers signed up for Supermaven. And Supermaven did well for itself raising $12 million from some investors: among them, Bessemer Venture Partners, OpenAI co-founder John Schulman, and Perplexity co-founder Denis Yarats.
Maven was founded in February. But it hadn't planned an exit. It was a good time, Jackson says.

"As Supermaven matured, we realized that the next step for the product wasn't just smarter models but new capabilities co-designed with the user interface to access those capabilities," he wrote in a post on Supermaven's blog. "Initially, we were building our own editor, but we were in touch with the Cursor team as well, and gradually coming to know them I felt that we could build a much more useful product together than Supermaven could build alone."

The Supermaven team will be able to design the editor UI together with the models under Cursor, Jackson added.

The acquisition comes after the company said it had received unsolicited offers valuing the company at as much as $2.5 billion from Benchmark, Index Ventures, Andreessen Horowitz, and more, sources exclusively told TechCrunch. Interest in the company, founded by Truell, Sualeh Asif, Arvid Lunnemark, and Aman Sanger in 2022, has skyrocketed in the past few weeks.

The market of AI coding tools is massive and will only increase, according to Polaris Research projections, whose value will stand at $27.17 billion by 2032. The vast majority of respondents in GitHub's latest dev poll report that they have adopted AI tools in some form. More than 1.8 million people —and ~50,000 businesses— pay for GitHub Copilot.

Plenty of AI-assisted coding startups exist, see Augment, Codeium, Magic, and Poolside. But Cursor is among the most popular options. According to our sources, now it brings $4 million a month.
