Headquartered in Occitanie (France) with cross-border operations in Germany, Altwy delivers 100% European software innovation to decouple compute growth from energy grid constraints.
Solving the Global Datacenter Grid & Resource Crisis
The rapid growth of AI, cloud workloads, and digital services is pushing physical infrastructure to its limits around the world. Communities are increasingly challenging new hyperscale data-centre developments because of well-founded concerns about grid capacity, high electricity demand, and pressure on local water resources. At the same time, enterprise infrastructure teams face rising legacy-software licensing costs and increasingly unpredictable pricing models.
At Altwy, we believe the answer is not simply to build more data centres, but to make the ones that already exist more productive, efficient, and sustainable.
Through intelligent hardware modernisation—a technology refresh that combines energy-efficient ARM, RISC-V, and x86 silicon with Altwy's lightweight software-defined stack—we help organisations increase compute density within their existing facilities. By delivering up to 4x greater performance per watt, depending on workload and configuration, we can unlock valuable rack space and power capacity. The result is more usable capacity from existing infrastructure, a lower carbon footprint, and less need for new megawatt-scale facilities.
Leadership Perspectives
“The AI revolution cannot happen on 20-year-old cloud architecture. We built Altwy to extract 4x more compute per watt, transforming existing datacenters from energy-guzzling bottlenecks into hyper-efficient powerhouses.”
Christophe Lambert
CEO, Altwy
“Before, IT was the answer to every problem. Today, it’s seen as the source of many. Let's flip the script once more so that computing becomes the solution again, not the problem.”

Proudly rooted in Occitanie, Altwy is supported by Bpifrance, France 2030, and the Occitanie Region. Operating across France and Germany, Altwy was selected by the French and German governments to represent the future of European cloud infrastructure at the Digital Sovereignty Summit in Berlin.
100% of our core R&D is conducted in Europe. Our software stack provides complete infrastructure independence with zero dependency on US hyperscalers or extraterritorial laws, offering ultimate data security for European, Asian, and security-conscious organizations globally.
Replacing legacy server footprints with high-efficiency multi-core architectures (ARM, RISC-V, next-gen x86) powered by Altwy frees up physical rack space and up to 75% of power capacity. You extract significantly more compute from your existing footprint without building new walls.
Say goodbye to massive hypervisor price hikes and public cloud cost spikes. Altwy brings the agility of cloud-native software directly to private and sovereign infrastructure at a fraction of the cost.
Transformation shouldn't mean operational risk. From allowing sysadmins and DevOps teams to test locally on workstations with Altwy One, to turning single servers into autonomous mini-datacenters with Altwy Access, up to multi-node orchestration, our modular software suite accompanies your growth step-by-step.
At Altwy, we believe that breakthrough technology is built by thriving teams in harmony with their environment.
As a 100% remote-first organization, we place absolute trust in our talent across France, Germany, and Europe. We offer complete geographical flexibility, eliminating unnecessary daily commutes to drastically reduce our collective carbon footprint while fostering true work-life balance and psychological wellbeing.
We prove every day that a hyper-growth tech company can operate with deep respect for natural resources. By minimizing our physical office infrastructure, optimizing our internal digital operations, and building energy-frugal software, we align our internal corporate culture with our core product promise: delivering maximum value with a minimal environmental footprint.
