About the Company
At JetBrains, code is our passion. Ever since we started back in 2000, we have been striving to make the world's most robust and effective developer tools. By automating routine checks and corrections, our tools speed up production, freeing developers to grow, discover, and create. We are now building services and agentic tools that provide AI coding agents and end users with deeper context about codebases. Our code retrieval service already delivers meaningful improvements in agent speed and task performance, and we aim to push this further - extracting richer insights than snippets alone at the scale of several hundred thousand repositories.
