Vates Makes Open Source Virtualization an Enterprise Bet

Vates is building an open-source virtualization stack for organizations that want control over the software beneath their servers. The Grenoble company develops XCP-ng, a type-1 hypervisor based on Xen, and Xen Orchestra, the browser-based layer for management, backup, disaster recovery, monitoring, and automation.

Olivier Lambert, CEO, Nithida Vialle, Chief Administrative Officer, and Julien Fontanet, Chief Operations Officer, co-founded Vates in 2012. The company has grown from three founders in the French Alps into a distributed team of nearly 150 people serving more than 1,000 customers in about 100 countries, according to Vates.

Vates matters now because enterprise virtualization is open for argument again. Broadcom's acquisition of VMware turned licensing, packaging, partner access, and migration risk into board-level infrastructure questions. Vates is betting that open code, direct engineering support, and the ability to leave without begging a vendor for permission can become a serious enterprise buying case.

About Vates

Vates began in Grenoble in 2012 as a small open-source software company. Xen Orchestra started as an internal tool, attracted early customer interest, and became a supported open-source product. The company later took stewardship of XCP-ng, combining the hypervisor and management layers into a broader platform.

The result is Vates VMS, a stack that joins XCP-ng and Xen Orchestra with XO Lite, XOSTOR, and XO Proxy. XCP-ng runs virtual machines on physical servers. Xen Orchestra gives infrastructure teams a web interface and API for managing pools, storage, networking, migration, replication, backup, and recovery. XOSTOR adds hyperconverged storage, while XO Proxy supports large or distributed backup environments.

The architecture matters because replacing a virtualization incumbent takes more than installing another hypervisor. Enterprise teams need lifecycle management, backup, automation, hardware compatibility, support, and a migration path that does not turn every weekend into a hostage negotiation with the maintenance window.

The Open-Source Business Model

Vates publishes its stack openly and sells support and services. The code, documentation, roadmap, and development activity are visible, while commercial customers can buy enterprise support and reach the engineers maintaining the products.

That model creates a different contract with customers. Organizations can inspect the technology, run it themselves, and retain an exit path. Vates still has to earn subscription revenue, but it cannot rely on obscurity or artificial lock-in as the moat. Product quality, support, and operating trust have to do the work.

The company says XCP-ng and Xen Orchestra have accumulated more than 2M downloads. Vates also reports more than 1,000 customers across about 100 countries, more than 65% growth in 2025, 90% of revenue outside France, and North America at close to half of the business. Those figures are not independently audited, but together they describe a business that has moved well beyond an open-source side project.

Why Virtualization Is Moving Again

Virtualization spent years looking like settled infrastructure. Then Broadcom completed its VMware acquisition in November 2023 and changed the economics around product bundles, licensing, support, and partner access. Customers started examining alternatives because a platform decision that once felt boring became financially and operationally visible.

Vates enters that opening with a sovereignty argument and a practical stack. Openness gives customers auditability and reversibility. The integrated platform gives operators the functions required to manage real infrastructure. The combination is the pitch: freedom is useful only when the system can survive production at 3 a.m.

The limits deserve equal attention. VMware built enormous product breadth, certification coverage, and an enterprise ecosystem over decades. Vates does not need to reproduce every feature, but it does need to prove migration reliability, hardware coverage, security response, partner delivery, and support at global scale.

Leadership, Funding, and the Next Test

Lambert, Vialle, and Fontanet remain at the center of Vates. On October 6, 2026, the founders announced the company's first institutional financing, a €30M investment from IRIS Growth and Bpifrance Large Venture. The three founders remain majority shareholders, and Vates says the existing open-source licenses and support model will remain in place.

The capital is intended to accelerate engineering, North American and European expansion, the distributor and integration ecosystem, and hiring. That makes the round less about discovering a market than serving one that arrived abruptly. Vates has spent more than a decade building the product. Now it has to compress several years of enterprise scaling into the window created by a dominant competitor's disruption.

The financing also raises the standard. Open source earns attention, but enterprise buyers pay for predictable upgrades, resilient backups, qualified partners, timely support, and a migration plan with fewer surprises than the contract they are leaving.

Culture and the Hiring Signal

Vates lists kindness, openness, solidarity, and freedom as its core values. The company supports 100% remote work and describes a distributed team centered in Grenoble with people and partners in the United States, India, England, and other markets.

The current careers page shows where the operating pressure sits. Vates is hiring for XCP-ng development, solution engineering, hardware compatibility and ecosystem leadership, technical support aligned with U.S. time zones, and education partnerships. Those are not decorative roles. They map directly to product depth, deployment expertise, channel growth, international support, and the next generation of open-source infrastructure talent.

Hiring is therefore a market signal, not a careers-page footnote. Vates is staffing the parts of the company that turn an alternative into infrastructure an enterprise can trust.

What Vates Has to Prove

Vates has a timely thesis: infrastructure buyers want more leverage over cost, architecture, and exit. It also has a real product stack, long operating history, active community, international customers, and fresh capital.

The next proof will come from migrations, production reliability, partner execution, and customer support. Vates must grow without diluting the open development and direct engineering access that made the company credible in the first place.

The virtualization market is no longer asking whether enterprises are willing to evaluate alternatives. It is asking which alternatives can carry the operational weight. Vates now has the money, market opening, and product foundation to answer that question in public.
