Chainguard, a leader in software supply chain security, has secured $356 million in a Series D funding round, pushing its valuation to $3.5 billion. This significant investment highlights the growing demand for safer software development practices.

The round was co-led by Kleiner Perkins, a new investor, and IVP, an existing backer. Other participants included Salesforce Ventures, Datadog Ventures, and all prior investors.

This new valuation is over three times higher than Chainguard’s previous $1.12 billion mark following its $140 million Series C.

Chainguard helps businesses build and maintain secure software by offering trusted open-source tools and preventing vulnerabilities in the development pipeline. The company reports $40 million in annual recurring revenue (ARR) and aims to surpass $100 million by the end of fiscal year 2026.

“Chainguard was founded on the belief that security shouldn’t slow innovation,” said CEO and co-founder Dan Lorenc. “We’re committed to making secure, reliable open-source software the industry standard.”

Founded in 2021, Chainguard has now raised a total of $612 million.

Cybersecurity Funding on the Rise
Chainguard’s growth reflects a broader trend in the cybersecurity sector. Just last week, Exaforce announced a $75 million Series A round led by Khosla Ventures, Mayfield Fund, and Thomvest Ventures.

In the first quarter of 2025, venture-backed cybersecurity startups raised over $2.7 billion—up 29% from the previous quarter.
