Chainguard, a cybersecurity company focused on securing open source software, has raised $280m in growth financing from General Catalyst’s CVF.
The latest investment follows Chainguard’s Series D round in April and brings its total raised in the past six months to $636m, with $892m secured to date. The company will use the new capital to meet surging demand for trustworthy open source software and strengthen its position as a leader in software supply chain security.
Founded to make open source software “trustworthy by default,” Chainguard provides hardened, secure, and production-ready builds of popular open source packages. As open source now represents 90% of code used by organisations worldwide, the company’s mission addresses growing concerns over vulnerabilities that could expose critical infrastructure to cyber threats.
Chainguard plans to channel the new funds towards expanding its go-to-market operations while maintaining a disciplined growth strategy. The company said the investment structure allows it to accelerate sales and marketing efforts without diluting equity, while continuing to invest in its core product and engineering innovation.
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. Dan is a standout founder who has built the business with incredible unit economics and intelligent capital allocation decisions.”
Chainguard chief financial officer Eyal Bar said, “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. This structure allows our commercial motion to fund its own growth while giving us the flexibility to double down on product and engineering — where our differentiation lies, and build the operational scale and financial profile required for the next stage of growth.”
The company recently achieved several milestones, including launching Chainguard Libraries for JavaScript, Java, and Python; introducing Chainguard VMs for secure container deployment; surpassing 1,700 zero-CVE images in its Chainguard Containers catalogue; and expanding its availability across major cloud marketplaces including Microsoft Azure, AWS, and GCP. Chainguard has also strengthened its leadership team with new appointments and earned recognition on the Forbes Cloud 100 and Fortune Best Workplaces in Technology lists.
Chainguard’s Series D fundraise earlier this year marked a key step in its growth trajectory, and this latest financing underscores continued confidence in its mission to make open source software safe and reliable for global enterprises.
