SonarSource Sàrl

SonarSource Sàrl builds automated code review and code quality and security tooling, positioned as a trust and verification layer for code that is human-written, generated by AI assistants, or drawn from third-party libraries. Founded in 2008, the company grew out of a free, open-source continuous code quality inspection tool that became an industry standard for automated code review; it is now trusted by over 7 million developers and 400,000 organisations. Its integrated code quality and security platform supports more than 30 programming languages, frameworks and infrastructure technologies, catching issues before they reach production. Customers include NASA, Microsoft, the Department of Defense and MasterCard.

Technical work spans static code analysis, code quality inspection, code security, automated code review, verification of AI-generated code and DevOps continuous inspection tooling. The company operates across the software development, developer tooling, AI code generation and verification, and application security fields.

SonarSource is organised as a team-based structure with minimal hierarchy, empowering autonomous teams to deliver work independently. The company describes a culture built from its founding, with an open-source heritage and core values of transparency, continuous innovation and collective intelligence. Hub offices are located in Switzerland, the United States, the United Kingdom, Singapore and Germany.
