Belfast’s Cloudsmith Raises $72M Series C Led by TCV
April 23, 2026 – 9:18 am
TCV led the Series B investment one year ago and now doubles down on the Series C. Insight Partners also returns. The focus? AI coding agents are rapidly generating software at such volume that traditional human code review is no longer sufficient, demanding a new approach to enterprise artifact management as the primary control and security layer.
Cloudsmith’s Solution:
Cloudsmith, the Belfast-based artifact management platform, has secured $72 million in a Series C round led by TCV, with participation from Insight Partners and other existing investors. The Series C follows their $23 million Series B investment just 13 months ago, highlighting strong belief in the company’s future.
The funds will support product development and global market expansion. Founded in Belfast in 2016 by Lee Skillen (CTO) and Alan Carson (now Chief Strategy Officer), Cloudsmith CEO Glenn Weinstein (formerly Chief Customer Officer at Twilio) is leading the charge.
The Investment Thesis:
The investment thesis centers on a pressing issue in enterprise software development: managing and securing an ever-growing number of "artifacts" generated by AI coding agents.
AI coding agents are creating code at unprecedented speeds and volumes, expanding the threat surface with open-source dependencies, novel vulnerability patterns, and increased regulatory scrutiny for demonstrating "secure by design" practices.
Cloudsmith’s cloud-native private registry and artifact management platform addresses these challenges:
- Hosting and distributing internal software packages
- Mirroring public registries in a controlled environment
- Applying security scanning, policy enforcement, and access controls to every package entering or leaving build pipelines
Cloudsmith differentiates itself from competitors like JFrog Artifactory and Sonatype Nexus by arguing that these tools are outdated for the AI-driven development paradigm. Recent product additions include an ML Model Registry and an Enterprise Policy Manager for supply chain-wide policy enforcement.
CEO Glenn Weinstein emphasized the Series C as a response to a fundamental shift in software creation:
"AI agents generate so much software, so fast, it’s nearly impossible for humans to carefully review everything."
