Chainguard, a company providing trusted open-source software solutions, has raised $280m in growth financing from General Catalyst’s Customer Value Fund (CVF).
The latest capital injection follows the firm’s Series D fundraise in April and brings its total secured funding to $892m. The company has raised $636m in just the past six months, highlighting accelerating investor confidence in its mission to make open-source software trustworthy by default.
Based in the US, Chainguard delivers secure, hardened, and production-ready builds of open-source software used by developers globally. Its solutions help organisations address the increasing risks within software supply chains, as open-source components now make up around 90% of the code used in enterprise applications.
The newly raised funds will be used to expand Chainguard’s go-to-market capabilities and accelerate product and engineering innovation. The company plans to strengthen its financial profile and operational scale while maintaining its focus on long-term value creation. The funding structure from General Catalyst also allows Chainguard to preserve equity while investing in strategic growth initiatives.
Chainguard CEO and co-founder Dan Lorenc said, “Open source powers the world, but the way it’s delivered and deployed often introduces risk. At Chainguard, we’re flipping that script: we guard open source from all the things that can go wrong with it, so engineering teams can build anything they want with it. We’re building the best, trusted source for open source. With this strategic capital, we can accelerate the adoption of Chainguard across more companies, helping engineering teams build faster, stay compliant, and eliminate risk.”
General Catalyst managing director and co-head of CVF Pranav Singhvi said, “Chainguard is defining a new category at the heart of modern infrastructure: trusted open source software. By solving one of the most pressing challenges in software development and deployment, the company is setting a new standard for engineering teams.”
Chainguard CFO Eyal Bar added, “This growth capital reflects the strength of Chainguard’s business, and how we’re scaling rapidly, operating with discipline, and planning for the long term. Our partnership with General Catalyst’s Customer Value Fund (CVF) is an important part of that strategy: it enables us to scale go-to-market investment without diluting ownership or slowing innovation.”
The company has achieved several milestones in recent months, including launching Chainguard Libraries for JavaScript, Java, and Python, and releasing Chainguard VMs for secure cloud-native deployments. It has also surpassed 1,700 zero-CVE images in its Containers catalogue and is now available on major cloud marketplaces including AWS, Microsoft Azure, and Google Cloud Platform.
Chainguard was recently listed in the Forbes Cloud 100 and recognised in Fortune’s Best Workplaces in Technology, underscoring its leadership in secure software innovation.
