JetBrains

Twenty-six years in, JetBrains is still privately held and bootstrapped, which shows up in how they make product decisions: as a private company, they're not driven by short-term targets or external expectations. The lineup spans the IntelliJ IDEA family of language-specific IDEs, the Kotlin programming language they created, TeamCity, YouTrack, Qodana, Fleet, and a growing AI stack including Junie and the Mellum model. Dogfooding is not a slogan here, it's literal: teams ship JetBrains tools by building with JetBrains tools.

The company runs a 15-office network across Europe, the US, and Asia, anchored by its Amsterdam holding entity and the original Prague engineering hub. Hiring leans on what you can do over where you went to school, and people turnover runs at less than half the industry norm, so teams stay together long enough to actually finish hard things.
