Chainguard Raises $280M to Expand Trusted Open-Source Security Platform

Chainguard, a cybersecurity startup focused on securing open-source software supply chains, has raised $280 million in growth financing from General Catalyst's Customer Value Fund (CVF), following a $356 million Series D round earlier in 2025. This latest funding brings its total capital raised to $892 million since its founding in 2021 and will be used to expand go-to-market operations, including sales and marketing teams across the U.S., Europe, and Asia. Chainguard provides hardened, production-ready open-source software components with minimal vulnerabilities, addressing significant risks in software supply chains that now comprise about 90% of enterprise application code. CEO Dan Lorenc emphasized that Chainguard aims to flip the traditional risk associated with open source by providing trusted, secure software that enables engineering teams to build safely and compliantly at scale. The financing structure allows Chainguard to preserve equity while investing aggressively in growth and R&D, especially as AI accelerates the adoption of new open-source projects in major regulated companies. With a valuation exceeding $3.5 billion and a forecasted $100 million in annual recurring revenue for 2025, Chainguard is positioned as a leading player in the modern infrastructure category of trusted open-source software solutions.
