Vates raises €30M growth round to scale open source virtualisation

Vates, the Grenoble company behind XCP-ng and Xen Orchestra, has raised a €30M growth round led by IRIS with Bpifrance – its first external funding in 14 years – to scale open source virtualisation for enterprises rethinking their VMware estates.

The round, announced by the company on 6 October 2026, is led by IRIS through its Growth fund, with Bpifrance investing from its Large Venture vehicle. And there is a detail in the announcement worth more than the headline number: the co-founders keep majority ownership, and every licence in the stack stays open source.

Fourteen years bootstrapped, one cheque

Vates has been profitable and self-funded since 2016 (company announcement, Oct 2026), so this is not a runway story. The money goes three ways: a next-generation platform covering performance, storage, security, automation and AI workloads; international expansion focused on North America and key European markets; and a partner ecosystem of distributors, integrators and service providers.

“We are not raising to change strategy, but to accelerate the one we have pursued from the beginning,” said CEO and co-founder Olivier Lambert in the announcement. Nicolas Herschtel, partner at IRIS, put the investor case just as plainly: Vates demonstrates that open source can meet market requirements.

From side project to Gartner’s quadrant

Vates was founded in Grenoble in 2012 as a software integrator. Xen Orchestra began as an internal tool before becoming an AGPLv3-licensed management product with paid support, and the XCP-ng platform the company built around it has been hosted under the Linux Foundation’s Xen Project since 2020 (company announcement, Oct 2026).

The numbers that convinced a growth fund, all from the same announcement: more than 1,000 customers across roughly 100 countries, more than 2 million downloads, growth above 65% in 2025, and 90% of revenue earned outside France – about half of it in North America. The team is 150 people. In 2026, Vates entered the Gartner Magic Quadrant for Server Virtualization Platforms for the first time, one of the few European vendors on it.

An $11.7bn market with a licensing problem

The segment Vates sells into is unusually easy to size, and unusually restless. The global server virtualisation market is projected to reach $11.7bn by 2030, growing at a 7.0% CAGR from 2024 (Lucintel, May 2026). The growth rate is not the story – the churn is. Vates frames the demand politely: licensing model changes, rising infrastructure costs and increasingly complex architectures are sending enterprises and public bodies looking for control over a layer that had not moved in a decade (company announcement, Oct 2026).

For scale against our own records this same week: Namespace raised $42M for AI coding infrastructure and Spiko raised $90M for tokenised cash funds. A €30M first round for a 14-year-old profitable company sits comfortably in that cohort – with rather less burn behind it.

The sovereignty trade is moving down the stack

So what does this round signal? We have spent two years talking about European sovereignty in AI models and cloud regions. The capital is now moving a layer down, to the software that runs the servers themselves. Bpifrance’s Large Venture fund sitting next to a growth investor in a Grenoble virtualisation vendor is the same pattern Europe’s defence and chip rounds have traced: when a layer becomes strategic, state-adjacent capital shows up – preferably before the next licensing invoice does.

I keep hearing that open source cannot be a venture-scale business in Europe. A bootstrapped company earning 90% of its revenue from exports, half of it in North America, is a decent counter-example (company figures, Oct 2026). The good news is that the buyer’s motivation here is not patriotism – it is price and control. That tends to last longer than a policy cycle.

What to watch next, in our fundraising data and beyond: whether Vates converts VMware migration projects into durable European platform share, and whether the Gartner placement turns inbound curiosity into enterprise standardisation. Europe keeps asking where its infrastructure champions will come from. Sometimes they have been sitting in Grenoble for 14 years, quietly profitable, waiting for the market to come to them. Keep watching this layer – the migration has only started!
