Vates Raises €30M to Scale Open Source Virtualization

The virtualization market has moved from grumbling about VMware to budgeting for alternatives. That shift creates an opening for vendors with credible software, but it also raises the standard: infrastructure teams need a platform, migration path, support organization, and partner network strong enough to carry systems that do not get weekends off.

Vates has raised €30M in its first institutional financing, approximately $33.8M at the October 6, 2026 European Central Bank reference rate. IRIS invested through its Growth fund and Bpifrance invested through its Large Venture fund. The Grenoble company says it has been profitable and self-funded since 2016.

The financing matters because Vates is promising acceleration without changing the ownership and licensing conditions that support its pitch. Co-founders Olivier Lambert, Nithida Vialle, and Julien Fontanet remain majority shareholders. Vates says XCP-ng and Xen Orchestra will remain open source under their existing licenses, while the company continues selling support and services around the same software available to non-subscribers.

What Vates Raised and Who Backed It

Vates announced the transaction on October 6, 2026. Official releases from Vates and Bpifrance describe it as the company's first funding round, but they do not assign a named series. La Tribune called it a Series A. Because the official investors are backing Vates through growth vehicles and the company is already profitable at international scale, the cleaner description is first institutional growth financing rather than a confident Series A label.

The Bpifrance announcement says the founders remain majority shareholders after the deal. No valuation, ownership percentages, or precise allocation of proceeds was disclosed. That leaves the transaction's governance message clearer than its pricing: the founders accepted outside capital without surrendering control.

Olivier Lambert remains CEO. Vates' current company history identifies Nithida Vialle and Julien Fontanet as the other co-founders, and the company's current team material lists them as Chief Administrative Officer and Chief Operations Officer, respectively. Older third-party posts use different executive titles, so those historical labels should not be carried into the current record.

Why Open-Source Virtualization Has a Window

Broadcom's acquisition of VMware in 2023 changed the economics and decision-making around a platform many enterprises had treated as permanent. Licensing changes, product packaging, and higher reported costs pushed infrastructure teams to reexamine how much control they retained over a foundational layer of their technology stack. The search for alternatives is now about more than finding another hypervisor. Buyers are measuring migration risk, interoperability, support depth, cost predictability, and whether they can leave the next vendor without repeating the same exercise.

Vates builds Vates VMS around two core open-source products. XCP-ng provides the server-virtualization platform based on the Xen hypervisor. Xen Orchestra provides management, orchestration, and backup. The company earns revenue from subscriptions, support, and services rather than placing a different core product behind the paying tier.

That model makes reversibility part of the commercial proposition. Open code does not eliminate switching costs, skills gaps, or implementation risk, but it changes what happens when a vendor alters its strategy. Customers retain access to the software and can continue operating or build from source while they decide what comes next. For public-sector organizations and European companies concerned about infrastructure sovereignty, that distinction is becoming a procurement issue rather than an ideological preference.

The Business Vates Is Trying to Scale

Vates reports more than 1,000 customers across about 100 countries, more than 65% growth in 2025, 90% of revenue outside France, and North America close to 50% of its business. The company says it has about 150 employees and more than 2M software downloads. These figures are company-reported rather than independently audited, but same-day reporting from Journal du Net and La Tribune corroborates the company's profitability, headcount, international footprint, and growth context.

The customer base places Vates beyond the stage where funding exists to prove basic demand. The money is intended to reduce the tradeoffs created by financing expansion only through current revenue. Vates can invest in engineering, commercial coverage, partner enablement, and enterprise support at the same time instead of forcing each priority to wait for the last one to pay back.

Independent reporting also supplies a useful restraint. Vates is benefiting from VMware disruption, but it does not yet offer the same breadth as the incumbent ecosystem. Winning a migration decision requires enough product coverage and enough operational confidence that an infrastructure team can accept the work of moving. The funding buys time and capacity to close those gaps while the market is actively reviewing alternatives.

Where the €30M Will Go

Vates says most of the financing will support technology. Planned work includes performance, storage, security, automation, and management for virtualization environments at larger scale, including new requirements created by AI workloads. Those priorities extend beyond feature competition. They determine whether the platform can support demanding environments without asking customers to assemble too much of the operating system around it themselves.

The second priority is international growth. North America is already Vates' largest market, and the company plans to strengthen sales and marketing there and across its main European markets. The third priority is the partner ecosystem, including distributors, integrators, service providers, and technology partners capable of delivering larger migration and transformation projects.

Partner capacity may decide how far the financing travels. Enterprise infrastructure changes are implemented through inventories, dependency mapping, backup plans, testing, training, and support coverage. A strong product can create demand, but service providers and integrators turn that demand into completed migrations. Vates needs both the software and the delivery network to scale together.

What the Financing Puts on the Record

The round gives Vates a stronger position during a rare period when virtualization buyers are willing to revisit foundational choices. It also makes the company's commitments easier to measure. Customers can watch whether XCP-ng and Xen Orchestra remain open under the same licenses, whether product investments land in the public stack, and whether the support model stays aligned with the software rather than becoming a path to restriction.

IRIS and Bpifrance are backing more than a European VMware alternative. They are backing the claim that an open-source infrastructure company can grow into a global enterprise vendor without weakening the control it offers customers. Vates has already built the product, revenue base, and international demand required to make that claim credible. The financing now moves the evidence into migrations, partner delivery, and the daily reliability of production systems.

For Europe, the opportunity is concrete. A regional infrastructure champion will not be created by describing sovereignty more passionately. It will be created when organizations can move critical workloads, obtain serious support, preserve an exit route, and keep operating after the strategy presentation has ended. Vates now has €30M to make that experience available at a much larger scale.
