The self-funded software company behind IntelliJ IDEA, the Kotlin language, and the Junie AI coding agent.
Everyone argues about the AI that writes code. Fewer people ask where the code actually gets written. For a large share of professional developers, the answer is a JetBrains window.
JetBrains builds integrated development environments - the software developers live inside all day. Its flagship, IntelliJ IDEA, launched in 2001 and set the company's reputation: not a text editor, but an environment that understands an entire project. It reads your code, flags mistakes as you type, refactors safely across thousands of files, profiles performance, and debugs line by line.
From that base, JetBrains built a family. PyCharm for Python. WebStorm for JavaScript and TypeScript. Rider for .NET and game development. GoLand, CLion, PhpStorm, RustRover. Each is tuned to a language rather than trying to be everything to everyone - a deliberate contrast to the one-editor-fits-all approach of lighter tools.
In 2011 the company did something unusual for a tools vendor: it created a programming language. Kotlin was designed to be a cleaner, safer companion to Java on the JVM. JetBrains then gave it away as open source. Google announced first-class Kotlin support for Android in 2017 and named it the preferred Android language in 2019.
Beyond editors, JetBrains ships the plumbing that follows code to production - TeamCity for continuous integration, YouTrack for issue tracking, and Qodana for automated code-quality checks. In 2025 it moved hard into AI with Junie, an agentic assistant that plans and executes multi-step coding tasks.
Professional software developers and engineering teams across nearly every industry - from startups to banks to Fortune 500 engineering organizations - plus students and educators. JetBrains reports more than 11 million recurring active users and gives free professional licenses to over 1.8 million students each year.
Writing software is repetitive and error-prone. JetBrains tools automate the boring parts - renaming across a codebase, catching bugs before they run, generating boilerplate - so developers spend energy on the actual problem. The team tools reduce the friction between "code written" and "code shipped," and AI now handles a growing slice of routine tasks.
One company quietly powers a large slice of professional coding. A look at the lineup.
The flagship IDE for Java, Kotlin and JVM languages. Unified into a single distribution in late 2025.
Open-source, cross-platform language created by JetBrains. Google's preferred language for Android.
IDE for Python and data science, with deep support for scientific and web workflows.
IDE for JavaScript, TypeScript and modern web development.
Cross-platform IDE for .NET, C# and Unity / Unreal game development.
The productivity extension for Microsoft Visual Studio that first put JetBrains in the .NET world.
CI/CD server for build automation and continuous delivery.
Issue tracking and agile project management for software teams.
Agentic AI coding assistant that plans and executes multi-step tasks - now integrated with GitHub.
Free code editors are everywhere. JetBrains sells something else: an environment that understands your whole project, not just the file on screen.
The distinction is real. A lightweight editor shows you text. A JetBrains IDE indexes your entire codebase, so its refactoring, inspections, and navigation know how every piece connects. That is what people are actually paying for - and why the tools feel heavier and smarter than free alternatives.
The business runs on subscriptions. Individuals and organizations pay annual or monthly fees, often through the All Products Pack bundle. Open-source projects, students and educators get free licenses - a long game that teaches the next generation on JetBrains tools. Kotlin stays free and open, driving the ecosystem rather than the revenue.
Then there is the money question. JetBrains has never raised venture capital. It reached an estimated $600M+ in revenue by selling something developers were happy to buy. Because no board demands quarterly growth, the company can optimize for product quality over the metrics a growth committee would chase.
Its AI strategy reflects that independence. Rather than making AI a separate paid island, JetBrains put a free tier into every IDE license in 2025 - unlimited completion, local models, and credit-based access to Junie - then layered a unified subscription on top. It went where developers already lived.

JetBrains launches the Junie AI coding agent, a free AI tier across all IDEs, and unifies IntelliJ IDEA.
The developer-tools market runs from free editors to AI copilots. JetBrains sits at the professional, deeply-integrated end of it.
Microsoft's Visual Studio and VS Code, GitHub Copilot, Cursor, Eclipse and cloud IDEs like Replit all compete for developer attention. In AI coding agents, Junie lines up against Cursor, Copilot and Claude Code. JetBrains' edge is decades of language-aware tooling underneath the AI layer.
JetBrains' core competence is program analysis - understanding code deeply enough to refactor it safely and catch errors before they run. Creating and stewarding Kotlin proved it could operate at the language level, not just the tooling level. That foundation is now the base its AI features build on.

No. JetBrains is privately held and has never raised external funding, financing its growth entirely through product sales.
Yes. JetBrains created Kotlin in 2011. Google announced first-class Android support in 2017 and named it the preferred Android language in 2019.
Junie is JetBrains' agentic AI coding assistant, launched in 2025, that can plan and execute multi-step coding tasks inside JetBrains IDEs and directly from GitHub.
