JetBrains Net Loss Explained: Margins, Financing and Warp's Rise

A record year that ended in the red

JetBrains, the Prague-based maker of IntelliJ IDEA, PyCharm and Kotlin, grew revenue 6.3% in 2025 to a record CZK 16,008 million. It still closed the year with a net loss of CZK 315 million, its first loss in filings going back to 2005, according to statutory accounts in the Czech business register compiled by Helgi Library 2. One developer-focused write-up converts that loss to roughly $14 million and frames it as the price of "chasing AI" while rivals such as Cursor scaled 5.

That framing captures part of the story but not the most immediate cause. Operating profit (EBIT) was still around CZK 751 million 2. The swing to a loss happened below the operating line. Net financing costs were CZK 1,078 million, compared with a CZK 810 million financing gain the year before, and that pushed pre-tax income negative 2. The accounts summary doesn't break those costs down. A jump of that size in a company holding large cash reserves points toward currency or investment-valuation effects rather than operational distress, but that is an inference, not something the filings spell out. JetBrains also ended the year with CZK 7,584 million in net cash, which makes it hard to call the company distressed 2.

The margin squeeze is real, though

The longer trend is less comforting than the headline loss. Gross margin fell to 10.7%, down from 53.7% in 2021, even though revenue rose every year in between 2. EBITDA dropped to CZK 918 million, a 5.7% margin 2. Commenters reading the same figures pointed to staff expenses rising 34.2% and a sharp increase in cash outflow from investing activities. They read this as a company hiring aggressively and putting money into something sizable 1. Others in that discussion suspected AI inference costs show up in a rising cost of services rather than in the investing line. They also noted that total assets grew even as net income fell 1.

The likely destination of that spending is visible. JetBrains has built Junie, a coding agent now embedded across its IDEs with a reported 343,000 users; Mellum, an open-sourced coding model; and Air, a standalone agentic environment launched in March 2026 5. The company says its AI tools passed six figures of active paid users in Q4 2025 2. Air is designed for a workflow in which developers mostly direct and review agents rather than type code. It supports Codex, Claude, Gemini CLI and Junie through the Agent Client Protocol, with components for in-IDE orchestration, team coordination and governance 5.

AI is therefore central to why JetBrains' margins have eroded. It just isn't the direct reason the 2025 bottom line turned negative.

Why the terminal matters

The more consequential question is strategic: where coding agents will actually live. One argument is that the terminal, not the IDE, is becoming the default home for agentic work 5. Tools like Claude Code read whole repositories, run shell commands, edit files and iterate on test failures without an editor open. OpenAI has rebuilt Codex CLI into a full-screen interface with parallel agent management. Gemini CLI competes on a generous free tier 5.

Warp is the clearest example of a terminal-native company taking advantage of that shift. It spent years with a large free user base and no business model, raising capital while essentially pre-revenue 4. Accounts of its early funding differ slightly. One describes a $23 million Series A led by GV with Figma's Dylan Field 4, while another lists a $6 million GV-led seed and a separate $17 million Series A led by Field 3. Both agree on a $50 million Sequoia-led Series B in June 2023 34. Warp reportedly took about 300 days to reach $1 million in annual recurring revenue and then began adding $1 million every 10 days 4. It reports nearly one million developers, customers including Docker, Ramp and Peloton, and use inside more than half the Fortune 500 4.

In April 2026, Warp open-sourced its terminal emulator and its Oz cloud-agent orchestration platform under MIT and AGPL licences, with financial support from OpenAI. Cloud products such as Warp Drive stay closed 3.

The reading

JetBrains is not collapsing. Its 2025 loss came mostly from financing swings, and it has a substantial cash cushion. The structural erosion of its margins is the real warning sign. It is spending heavily to turn a profitable IDE franchise into an agent platform, while terminal-first competitors with venture backing and open-source distribution chase the same developers. JetBrains' interoperable approach with Air hedges well against that. Whether it can restore margins while paying for AI is the question its 2026 accounts will need to answer.
