In February, AI coding startup Windsurf was once in talks to boost a large new spherical at a $2.85 billion valuation led by means of Kleiner Perkins, at double the valuation it hit six months previous, resources instructed TechCrunch on the time. That deal didn’t occur, in line with a supply aware of the topic. As an alternative, information broke in April that the startup deliberate to promote itself to OpenAI for more or less the similar valuation: $3 billion.
Whilst that deal famously fell aside, one larger query stays: if the startup was once rising that speedy and attracting VC passion, why wouldn’t it promote in any respect?
Insiders inform TechCrunch that for all of the reputation and hype round AI coding assistants they may be able to in fact be vastly money-losing companies. Vibe coders normally, and Windsurf specifically, will have such pricey constructions that their gross margins are “very adverse,” one individual acquainted with reference to Windsurf instructed TechCrunch. That means it value extra to run the product than the startup may just fee for it.
That is because of the prime prices of the usage of huge language fashions, the individual defined. AI coding assistants are in particular confused to at all times be offering the newest, maximum complicated, and most costly LLMs as a result of type makers are in particular fine-tuning their newest fashions for enhancements in coding and similar duties like debugging.
This can be a problem compounded by means of fierce pageant within the vibe coding and code-assist marketplace. Opponents come with firms that have already got massive buyer bases like Anysphere Cursor and GitHub CoPilot.
The most simple trail to making improvements to margins on this industry comes to the startups development their very own fashions, thereby getting rid of prices of paying providers like Anthropic and OpenAI.
“It’s an excessively pricey industry to run in the event you’re now not going to be within the type recreation,” mentioned the individual.

However that concept comes with its personal dangers. Windsurf’s co-founder and CEO, Varun Mohan in the long run made up our minds in opposition to development its personal type — a pricey endeavor, the individual mentioned.
As well as, type makers are already competing without delay. Anthropic provides Claude Code and OpenAI provides Codex, as an example.
Promoting the industry was once a strategic transfer to fasten in a prime go back ahead of it may well be undermined by means of the very firms that equipped its AI, together with OpenAI and Anthropic, which have been additionally getting into the AI coding marketplace.
More than one other people imagine that the similar force on margins Windsurf confronted may well be impacting Anysphere, the maker of Cursor, in addition to vibe coders like Adorable, Replit and others.
“Margins on all the ‘code gen’ merchandise are both impartial or adverse. They’re completely abysmal,” mentioned Nicholas Charriere, founding father of Mocha, a vibe coding startup and backend webhosting resolution serving small and medium companies (SMBs). He added that he believes the variable prices for all of the startups within the sector are very shut, most probably inside 10% to fifteen% of each other.
Not like Windsurf, Anysphere has been rising so speedy that it intends to stay an unbiased corporate, having already grew to become down acquisition provides, together with, stories say, from OpenAI.
And Anysphere introduced in January that it is trying to construct its personal type, which might give it extra keep watch over over its bills. In July, the startup employed two leaders from Anthropic’s Claude Code workforce, the Knowledge reported, however two weeks later, those staff returned to paintings at Anthropic.
Along with development a type, Anysphere may just be expecting the price of LLMs to lower through the years.
“That’s what everybody’s banking on,” mentioned Eric Nordlander, a basic spouse at Google Ventures. “The inference value lately, that’s the most costly it’s ever going to be.”
It’s now not completely transparent how true this is. Relatively than falling as anticipated, the value of one of the crucial newest AI fashions has risen, as they use extra time and computational assets to maintain sophisticated, multi-step duties.
When that may alternate is still noticed. On Thursday, as an example, OpenAI presented a brand new flagship type GPT-5 with charges which can be considerably lower than its competitor, Anthropic’s Claude Opus 4.1. And Anysphere instantly presented this type as a call for Cursor customers.
Anysphere has additionally just lately modified its pricing construction to go alongside the larger prices of operating Anthropic’s newest Claude type, in particular to its maximum energetic customers. The transfer stuck a few of Cursor shoppers by means of wonder, since they didn’t be expecting further fees on best of its $20-per-month Professional plan. Anysphere CEO Michael Truell later apologized for unclear conversation concerning the pricing alternate in a weblog submit.
That is the rock and the exhausting position. Even supposing Cursor is without doubt one of the most well liked AI programs, having reached $500 million in ARR in June, the corporate’s person base will not be so dependable to the product if every other corporate develops a device this is awesome to Cursor, buyers say.
Anysphere didn’t reply to a request for remark.
Given the aggressive panorama and the prices, Windsurf’s resolution to get out might end up to be comprehensible. After the OpenAI deal fell via, the founders and key staff left to sign up for Google in a deal that ended in a $2.4 billion payout to key shareholders. The rest industry then bought itself to Cognition.
Whilst many, together with distinguished VCs, criticized Mohan for leaving roughly 200 staff with out roles at Google, a supply aware of the deal insisted the purchase in fact maximized the results for all staff.
Past Cursor, different AI coding gear also are some of the quickest rising startups of the LLM technology like Replit, Adorable, Bolt and they all depend on type makers, as smartly.
Moreover, if this very talked-about industry sector, already producing masses of hundreds of thousands in income or extra a 12 months, has problem development on best of type makers, what may it imply for different, extra nascent industries?
