JetBrains' First Loss: A Financing Swing and a Margin Squeeze

What happened

JetBrains, the Prague-based maker of IntelliJ IDEA, PyCharm and the Kotlin language, has reported its first net loss in two decades of public filings. Statutory accounts filed in the Czech business register show record 2025 revenue of CZK 16,008 million, up 6.3%. The company still finished the year CZK 315 million in the red. This is the first loss in filings going back to 2005 2. One widely shared commentary converted the figure to roughly $14 million 3.

The news set off a lively Hacker News thread. Moderators retitled the discussion twice: first because the original framing was too gloomy for a company in no financial danger, and then, arguably, to something too rosy 1. That back-and-forth captures the core problem with this story. The headline number is real, but what it means depends on which line of the income statement you read.

The loss came mostly below the operating line

The most important detail is where the red ink appeared. JetBrains still made an operating profit (EBIT) of about CZK 751 million 2. The loss came from net financing costs of CZK 1,078 million, compared with a financing gain of CZK 810 million the year before. That swing of nearly CZK 1.9 billion was enough to push pre-tax income below zero 2. The available figures don't say what drove the financing line. JetBrains also ended the year with net cash of CZK 7,584 million, which is hardly the balance sheet of a distressed business 2.

On a strict reading, then, the claim that JetBrains "lost money chasing AI" doesn't match the accounts. Without the financing reversal, the company would have reported a profit.

But the operating picture is genuinely tighter

That doesn't mean nothing changed. EBITDA fell to CZK 918 million, a margin of just 5.7% 2. Gross margin has dropped to 10.7%, down from 53.7% in 2021, even though revenue grew every year in between 2. Costs are rising much faster than sales. Staff expenses rose 34.2% and operating expenses rose 26.5%, against revenue growth of about 6% 1.

Those numbers fit a company spending heavily to find its place in an AI-shaped future for software development. Nobody yet knows what that future looks like, which makes the bet harder 1. JetBrains itself has not linked the margin squeeze to AI costs. Arguments that the cost of serving AI features is to blame remain analysts' inference for now 2.

The AI bet, and the competition

The more pessimistic reading treats the loss as evidence that the IDE era is ending 3. In this view, agentic tools that work from the terminal are taking over. Claude Code, OpenAI's rebuilt Codex CLI and Gemini CLI can read a whole repository, run commands and iterate on test failures without an editor open 3. The same piece contrasts JetBrains' loss with Cursor reportedly reaching $4 billion in annual recurring revenue. It lists JetBrains' answers:

• Junie, a coding agent built into its IDEs, with a reported 343,000 users
• Mellum, an open-sourced coding model
• Air, an "Agentic Development Environment" launched in March 2026, in which developers guide and review agents rather than write code 3

Air supports several third-party agents, including Codex, Claude, Gemini CLI and Junie, through the Agent Client Protocol. It also adds team coordination and governance features covering policy, auditing and cost control 3.

A JetBrains representative pushed back on one common complaint: that AI work has pulled resources away from the core IntelliJ platform. Junie involves roughly 30 to 40 people, the representative said, while IntelliJ headcount runs into the thousands 1. That doesn't settle where the overall cost growth is going. It does undercut the idea that a small agent team is hollowing out the flagship product.

The reading

Both extreme takes miss the mark. "First-ever loss" overstates the immediate trouble, because the accounting swing was financial, not operational, and JetBrains has plenty of cash. "Record revenue, nothing to see" ignores a multi-year margin collapse and costs rising far faster than sales.

The fairer conclusion is that JetBrains is in a costly transition. It is spending on headcount and AI products to stay relevant as agents change how code gets written. Its revenue growth is modest next to AI-native rivals. Its strategy with Air is to become the coordinating layer for agents from many vendors rather than compete with them head-on. Whether that works will show up in the operating margin, not the financing line. That margin is the number to watch in next year's filing.
