Mistral-Backed Clastix Raises $3.2M to Build Europe's Sovereign Kubernetes

Jan de Vries · 2026-09-24

Clastix just closed its first outside funding round — and it's a signal worth paying attention to if you care about where AI infrastructure is heading. The Naples-based company raised €2.9 million (about $3.2 million) in a Seed round led by CDP Venture Capital Sgr. Mistral and Vertis SGR also joined in through the Vertis Venture 6 Digital Sud fund, which gets partial backing from the European Union's Next-Generation EU program. Not bad for a team that started out solving a problem most people hadn't even named yet. ### What Clastix Actually Does (And Why It Matters) Founded in 2020 by Adriano Pezzuto and Dario Tranchitella, Clastix builds infrastructure software that makes running Kubernetes at scale less of a headache. Both founders spent years managing Kubernetes deployments inside big enterprises, so they knew exactly where the pain points were. Their first project, Capsule, brought native multi-tenancy to Kubernetes. Then came Kamaji, which lets tenant control planes run as pods on shared infrastructure instead of dedicated machines. Clastix calls this eliminating the "control plane tax" — and honestly, that's a pretty good way to put it. Since then, they've rolled both technologies into a single commercial platform called kMetal. It's already running in production with infrastructure teams at AI labs, telecom companies, cloud providers, and public sector organizations. Their customer list includes Fastweb, NVIDIA, and Mistral. ### Why Mistral Backed This Round When Mistral's co-founder and CTO Timothée Lacroix talks about Clastix, he doesn't mince words. > "Clastix is the backbone of our Kubernetes infrastructure — their work on multi-tenancy and managed control planes helps us enable our training and inference clusters at scale, with the efficiency that frontier AI demands. By backing Clastix, we're investing in Europe's AI stack. A sovereign AI ecosystem isn't just about models — it's about the infrastructure layer that makes them run." That last part is key. The next phase of AI won't be decided by models alone. It'll be decided by who controls the infrastructure underneath them. ### The Bigger Picture: Europe's Infrastructure Play Clastix is positioning itself as a European alternative to hyperscaler-dependent infrastructure. The pitch? Give enterprises and AI-focused organizations hyperscaler-grade Kubernetes operations while keeping control over their own hardware and data. Alessandro Scortecci, Chief Investment Officer for Direct Investments at CDP Venture Capital, put it this way: "We are proud to support a team that combines engineering excellence, market vision, and global ambition. This investment reflects CDP Venture Capital's commitment to backing strategic technologies developed in Italy that can strengthen Europe's technological sovereignty and long-term competitiveness." ### What's Next for Clastix The fresh capital will go toward product development, customer success, solutions engineering, and go-to-market expansion as the company scales kMetal. Over the next three years, Clastix plans to grow its headcount to meet rising customer demand and build out capabilities for larger enterprise teams. They'll also keep investing in Kamaji, their open-source Hosted Control Plane engine, which stays free and unchanged under the Apache 2.0 license. As Pezzuto put it: "The next phase of AI won't be decided by models alone but by who controls the infrastructure layer beneath them. This funding goes toward building that layer for what's coming: expanding our R&D to better support AI-scale workloads, and growing our team to bring it into new markets as they build their AI infrastructure." ### The Bottom Line Clastix isn't trying to be the flashiest company in the room. They're building the unglamorous plumbing that makes AI work at scale — and they're doing it from Naples, not Silicon Valley. If Mistral's backing is any indication, that plumbing might end up being pretty valuable.
