Chainguard, Inc.

Chainguard, Inc. is a privately held cybersecurity company founded in 2021 with a mission to make open-source software trustworthy by default and secure the software supply chain. Headquartered in Kirkland, Washington, the company operates with a remote-first model, though its registered corporate office is located there. Chainguard champions a "start left" philosophy, embedding security from the initial stages of the development lifecycle rather than as an afterthought.

Chainguard provides a suite of products and services designed to reduce software supply chain risk. Its core offerings include hardened, minimal container images with zero known vulnerabilities (0CVEs), malware-resistant language libraries (Chainguard Libraries), and secure virtual machine images (Chainguard VMs). These products are built and continuously updated through the "Chainguard Factory," a system that ensures end-to-end integrity and provides Software Bill of Materials (SBOMs) and attestations for transparency. The company also offers educational resources through Chainguard Academy and supports open-source projects via Chainguard EmeritOSS.

Chainguard has experienced rapid growth, securing $280 million in growth financing in October 2025, following a $356 million Series D round in April 2025, bringing its total funding to approximately $892 million and valuing the company at $3.5 billion. The company reported annual recurring revenue (ARR) of $40 million in fiscal year 2025, with projections to exceed $100 million before fiscal year 2026. Led by CEO and co-founder Dan Lorenc, Chainguard is recognized as a leader in the cybersecurity space, particularly for its focus on securing open-source software in the age of AI. Its recent launch of Zero-CVE EKS Add-Ons on AWS Marketplace caters to regulated industries requiring FIPS-validated container images, further solidifying its market position.
