Belfast-based Cloudsmith has raised a $72m (£53.4m) Series C round to accelerate product development and expand its go-to-market capabilities.

Cloudsmith is a cloud-native artifact management platform ‘built for the age of AI’. As AI coding agents transform the pace and scale of software development, Cloudsmith gives engineering teams the infrastructure to manage, secure and govern packages across different formats and environments.

The firm says the artifact management market has been fundamentally reshaped by AI agentic software development. As AI coding agents generate code at unprecedented velocity and volume, the software artifacts and dependencies they produce introduce an increasing threat.

Cloudsmith strives to remedy this, with its platform giving engineering teams the scale and visibility needed to govern every package.

“AI agents generate so much software so fast [that] it’s nearly impossible for humans to carefully review it all,” says Glenn Weinstein, CEO of Cloudsmith. 

“Cloudsmith has the scale and the broad view across the open-source ecosystem to protect enterprises against the new kinds of threats that AI-driven development introduces.”

The Series C round was led by TCV and with participation from Insight Partners, along with investments from other existing investors. It follows Cloudsmith’s successful £18m Series B round a year ago.
