Belfast tech firm Cloudsmith has raised £53 million in Series C funding.
Cloudsmith has built a platform for the era of AI-driven software development and is used by some of the world’s leading enterprises.
It only raised Series B funding a year ago and both rounds were led by TCV.
Cloudsmith says it is seeing increasing numbers of existing customers, including Fortune 500 and Global 2000 companies, replacing legacy tools and upgrading to its cloud-native platform.
According to the firm, enterprises that adopt AI-coding agents are also turning to it to provide the guardrails and governance their software supply chains require.
The fresh financing included participation from Insight Partners and other existing investors.
“Cloudsmith is the only platform built for the way software is being developed today — by AI agents. We’re never going back to hand-crafted software,” said Glenn Weinstein, CEO of Cloudsmith.
“AI agents generate so much software, so fast, it’s nearly impossible for humans to carefully review it all. 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.
“TCV and Insight Partners both recognise this profound shift, and their backing is helping Cloudsmith scale up for the massive wave of adoption of AI agents across enterprise software teams.”

Morgan Gerlak, partner at TCV, said: “Having led Cloudsmith’s Series B and now its Series C, TCV is proud to deepen our partnership with a company we see as defining artifact management for the AI era.
“As AI shapes the software supply chain, we believe Cloudsmith is uniquely positioned to become a platform enterprises rely on for compliance, control, and security at global scale.”
Thomas Krane, managing director at Insight Partners, added: “In an era increasingly defined by AI-driven development, securing the software supply chain is critical.
“As a cloud-native offering, Cloudsmith is well positioned to do this – providing the scale and reliability needed to help power enterprise and AI-driven builds and mitigate emerging risks.
“We believe in Cloudsmith’s vision to secure the software supply chain by serving as a curated, AI-ready solution for enterprises of all sizes.”
