Sourcery is a London-based software company specializing in AI-powered code review and code improvement tools. Its main product is an AI code reviewer that provides instant, actionable feedback, detects bugs and security issues, and suggests improvements for software developers and engineering teams. Sourcery integrates with popular developer platforms such as GitHub, GitLab, and IDEs, and supports reviews across 30+ programming languages.
Sourcery was founded in 2018 by Brendan Maginnis, Timothy Gilboy, and Nicholas Thapen. The company's vision is to use advanced program analysis, machine learning, and interactive feedback loops to transform how software is developed—making code reviews faster, higher quality, and more collaborative. The company has grown as a trusted partner to developers, aiming to reduce the billions of hours spent annually on reviewing and refactoring code.
Sourcery has raised a total of $1.87 million over two funding rounds. The most recent, a seed round in January 2022, secured $1.75 million from investors including Forward Partners, Runa Capital, Techstars Ventures, Acequia Capital, CapitalX, Angel Invest Ventures, and others. Valuation specifics have not been publicly disclosed, but the funding rounds suggest steady investor confidence in the company's innovative products and growth prospects

Sourcery is guided by the belief that software should evolve organically through collaboration between human developers and intelligent automation. The company’s mission emphasizes empowering teams, fostering innovation, and reducing friction in software development. From its leadership to its product focus, Sourcery values transparency, security (including no code retention and self-hosting), and continuous learning and improvement.
Sourcery’s user base consists primarily of software developers, engineering teams, and quality assurance engineers. The product is used by developers across a broad spectrum of roles—backend, frontend, full-stack, test automation, and infrastructure. The company’s freemium model attracts open source projects and individual developers, while its team and enterprise features appeal to larger organizations seeking automation and code quality improvements. The company maintains a small but global team (2–10 employees) and a vibrant community of users who contribute feedback and participate in closed betas for emerging features.
