Cloudsmith: Funding Rounds, Investors & CEO

About Cloudsmith

Cloudsmith sells a fully managed artifact management platform to software teams at large companies. Artifacts are the packages, containers and AI models that developers build software from. Cloudsmith keeps them in one cloud repository that supports more than 30 formats, including npm, Python, Maven and Docker. It scans each artifact for malware, vulnerabilities and license problems, blocks anything that breaks a customer's policies, and delivers software to developers and customers from 600 network locations worldwide.

Alan Carson and Lee Skillen founded Cloudsmith in Belfast, Northern Ireland, in 2016. Carson is now chief strategy officer and Skillen is CTO. Glenn Weinstein, formerly Twilio's chief customer officer, became CEO in 2023. Its customers include Thrivent, Carta, PagerDuty, Font Awesome, Diligent and RabbitMQ. In 2025, 75% of Cloudsmith's revenue came from U.S. customers. It had 130 employees in April 2026, most of them in Belfast, according to the BBC.

Why Investors Backed Cloudsmith

Investors backed Cloudsmith because it sits where outside code enters a company's software. AI coding agents now add packages faster than people can review them, so that entry point needs automatic checks. Cloudsmith runs those checks in a cloud registry, and many customers moved to it from JFrog and Sonatype. TCV led its Series B in 2025 and its $72 million Series C in April 2026.

The problem it targets

In 2025, over 90% of a typical enterprise application came from open-source and third-party code. Attackers know this. In March 2025, the tj-actions/changed-files compromise hit more than 23,000 code repositories. In April 2026, attackers pushed malicious releases of Axios, an npm package with about 100 million weekly downloads. Regulation adds pressure, too. From September 2026, the EU Cyber Resilience Act requires sellers to report exploited flaws within 24 hours, Diginomica reported.

What the product does

Cloudsmith keeps every package, container and model a company uses in one cloud repository. It also proxies and caches public registries such as npm and PyPI, which shields teams from outages there. Cloudsmith scans each package on upload and checks it again as new threats appear. Customers write policies in OPA Rego to block or quarantine risky packages. For example, a cooldown policy holds back new releases until they reach a minimum age. Cloudsmith runs as one shared, multi-tenant cloud service. Its CEO wrote in 2023 that JFrog's and Sonatype's tools still ran one instance per customer.

Progress so far

Cloudsmith's annual recurring revenue grew 103% year-over-year. That followed growth of nearly 150% in 2024. In 2025, package deliveries rose 352% and headcount rose 92%. Some customers came from the incumbents. For example, ConstructConnect and an unnamed electronics company both switched from JFrog. PagerDuty gets 50% cost savings with Cloudsmith.

Who backs it

Frontline Ventures led the £2.1 million seed round in 2019, with MMC Ventures and Techstart Ventures. Tiger Global led the $15 million Series A in 2021, and MMC led an $11 million Series A2 in 2023. TCV then led both later rounds, and Insight Partners joined each time. Cloudsmith has raised $124 million in total. TCV partner Morgan Gerlak joined the board with the Series B, Frontline wrote. MMC co-founder Bruce Macfarlane is also a director. Gerlak says TCV sees Cloudsmith as "defining artifact management for the AI era."

How the market is moving

The main incumbent is growing, and it is moving to the cloud. On August 6, 2026, JFrog reported second-quarter revenue of $163.8 million, up 29% from a year earlier. Its cloud revenue rose 53% to $87.5 million. JFrog's CEO said AI is accelerating the volume of software artifacts flowing into production. Vendors are also teaming up on security. In September 2026, Cloudsmith joined Athena, a Chainguard-led coalition whose members include JPMorgan Chase, Cisco and Docker. Cloudsmith also cites Gartner research that 44% of organizations plan to significantly increase spending on supply chain cybersecurity.
