Chainguard, the cybersecurity firm laser-focused on locking down software supply chains, has raised more than $800 million to stop cyberattacks before they start. The company’s total funding now sits at approximately $892 million, with a valuation of $3.5 billion.

The funding breakdown

Chainguard closed a $356 million Series D round on April 23, 2025, which established its $3.5 billion valuation. Then in October 2025, it tacked on another $280 million in a growth round.

Kleiner Perkins, Sequoia, IVP, and General Catalyst have all backed the company.

Founded in 2021 by Dan Lorenc and Matt Moore, both former Google engineers, Chainguard is headquartered in Kirkland, Washington. Lorenc previously worked on sigstore, an open source project designed to make software signing and verification easier.

The company’s annual recurring revenue reached $40 million, with projections to surpass $100 million by the end of fiscal year 2026.

Why software supply chains matter to crypto

Chainguard provides hardened container images, language libraries, and virtual machine images that are engineered to eliminate known vulnerabilities. The approach is particularly relevant for blockchain infrastructure, as supply chain compromises have targeted npm packages, Python libraries, and other components commonly used in crypto development.

AI-driven threats have added another layer of complexity. As large language models get better at generating convincing code contributions, the risk of malicious code being introduced through seemingly legitimate open source pull requests has increased.

What this means for the broader security market

Chainguard was recognized as a Leader in the 2026 Gartner Magic Quadrant for Software Supply Chain Security.

The timing of this funding also coincides with intensifying regulatory scrutiny around open source software consumption. Governments worldwide are increasingly requiring organizations to maintain software bills of materials, essentially ingredient lists for the code running their systems.
