Chainguard
Chainguard is a Cloud & Application Security company founded in 2021 and based in Kirkland, United States. It has raised $892M in total funding, most recently a Series D in 2025 at a $3.5B valuation.
Founded in 2021 by Dan Lorenc, Kim Lewandowski, Matt Moore, Ville Aikas, and Scott Nichols, Chainguard set out to be 'the safe source for all open source.' Its flagship Chainguard Images are minimal, hardened container images built from source on a continuously-updated, low-to-zero-CVE distribution (Wolfi), giving enterprises a trusted supply of base images, language libraries, and VMs. The founding team came out of Google, where several created the open-source supply-chain projects Sigstore and SLSA. Chainguard raised a $356M Series D in April 2025 at a $3.5B valuation, then added $280M in growth financing from General Catalyst in October 2025, bringing total funding to roughly $892M.
After high-profile supply-chain attacks like SolarWinds and Log4Shell, Chainguard turned 'secure-by-default open source' into a fast-growing business and a category-defining bet on hardened software provenance.
