JetBrains

JetBrains is a Czech software company founded in 2000 that develops integrated development environments (IDEs) and developer productivity tools used by software engineers worldwide. Its flagship product, IntelliJ IDEA, is one of the most widely adopted Java and JVM IDEs in the industry, while its ecosystem includes PyCharm (Python), WebStorm (JavaScript/TypeScript), GoLand (Go), CLion (C/C++), Rider (.NET), DataGrip (databases), and Fleet (next-generation multi-language IDE). JetBrains also created and maintains Kotlin, a statically typed programming language that is now the preferred language for Android development and is widely adopted for backend services. The company has expanded into AI-powered tooling with JetBrains AI Assistant and Junie, an autonomous AI coding agent. As of 2025, JetBrains serves more than 12.5 million recurring active users globally, including engineering teams at 88 of the Fortune Global Top 100 companies. The company operates from 13 offices across Europe, the Americas, and Asia, and remains privately held and bootstrapped with no external venture funding — operating profitably on subscription and license revenue since its founding.
