Kerys Software, a startup focused on IT infrastructure, has raised €6.2 million (US$7.3 million) in pre-seed funding.

The funding round was led by Daphni, Seedcamp, and Backtrace, with contributions from Kima Ventures and individual investors.

Founded in 2024 by Thomas Brethomé, Sébastien Domergue, Sylvain Cassier, and joined by Thomas Girard in 2025, Kerys aims to improve IT infrastructure efficiency and reduce environmental impact.

The company specializes in virtualizing workloads, allowing multiple environments to share a single workstation or server.

The funding will be used to expand Kerys’ team, develop its products, and support international growth.

🧠 Food for thought

1️⃣ The decades-long evolution of virtualization technology

KERYS Software’s approach builds on a long history of infrastructure consolidation that began in the 1970s when IBM first introduced virtual machines that could run multiple operating systems on a single physical computer 1.

This evolution continued through several distinct phases: from basic virtualization to Converged Infrastructure (integrating pre-packaged servers, storage, and networking), then to Hyper-Converged Infrastructure (software-defined architecture), and finally to Composable Infrastructure (dynamically allocated resource pools) 2.

The persistent challenge throughout this evolution has been the same one KERYS aims to solve: traditional IT infrastructure typically runs at very low utilization rates, with servers spending much of their lifetime idling, creating enormous inefficiency 3.

Statistically, IT sprawl can consume up to two-thirds of an organization’s technology budget in traditional environments, leaving limited resources for innovation and new initiatives 4.

KERYS’s virtualization approach represents the latest iteration in this evolution, with their focus on workload consolidation specifically designed to address both cost and carbon emission challenges simultaneously.

2️⃣ Regulatory compliance driving new infrastructure requirements

The EU’s NIS2 Directive, which came into force in January 2023, is creating urgent compliance requirements across 18 industry sectors, pushing organizations to implement stronger cybersecurity measures and more resilient IT systems 5.

The directive introduces substantial penalties for non-compliance, including fines of up to €10 million or 2% of global annual turnover, creating significant financial incentives for organizations to update their IT infrastructure 6.
