## History

JetBrains, initially called IntelliJ Software, was founded in 2000 in Prague by three Russian software developers: Sergey Dmitriev, Valentin Kipyatkov and Eugene Belyaev. The company's first product was IntelliJ Renamer, a tool for code refactoring in Java.
In 2012 CEO Sergey Dmitriev was replaced by Oleg Stepanov and Maxim Shafirov.
In 2021 The New York Times stated that unknown parties might have embedded malware in JetBrains' TeamCity CI/CD software that led to the SolarWinds hack and other widespread security compromises. In a press release, JetBrains said they had not been contacted by any government or security agency and had not "taken part or been involved in this attack in any way". The CEO of one of the affected companies, SolarWinds, "asked about the possibility that software tools made by JetBrains, which speeds the development and testing of code, was the pathway, Mr. Ramakrishna said there was still no evidence".
In response to the 2022 Russian invasion of Ukraine, the company suspended sales and R&D activities in Russia indefinitely as well as sales in Belarus. JetBrains' Russian legal entity was liquidated on 21 February 2023.
Effective 1 February 2024, Kirill Skrygan replaced Max Shafirov as CEO.
