How Deutsche Telekom, PhysicsX & Nvidia are Fueling Industry

How Deutsche Telekom, PhysicsX & nvidia are fueling industry. PhysicsX's AI-native engineering platform has been made available on Deutsche Telekom's Industrial AI Cloud, powered by NVIDIA accelerated computing PhysicsX has formed a partnership with Deutsche Telekom and NVIDIA in a bid to connect Europe's advanced industries. The partnership comes amid a fragmented global market and aims to strengthen European infrastructure. By blending AI platforms, cloud capability and digital infrastructure, the collaboration aims to boost manufacturing resilience. Establishing AI infrastructure. PhysicsX is a physical AI company which builds new software to deliver AI enablement across an entire engineering lifecycle. It partners with leaders in aerospace and defence, automotive, semiconductors, materials & energy and renewables. Now, its AI-native engineering platform is available to use across Deutsche Telekom's Industrial AI Cloud. The Industrial AI Cloud is Europe's new industrial AI infrastructure, which is powered by NVIDIA accelerated computing. By partnering together to blend technologies and infrastructure, PhysicsX is turning cloud capability into real-world engineering impact for Europe's industry. It is doing this through the connecting of sovereign infrastructure, enterprise-grade interoperability and an AI-native software stack. The joint venture marks the first step in Europe's journey towards establishing its own AI gigafactories, which are high performance spaces where physics-based AI will speed how industries design, test and manufacture intricate systems and specialised machines. Each company brings its own innovation and technology: * PhysicsX has the AI application * NVIDIA has the accelerated computing capacity * Deutsche Telekom powers the infrastructure, operations and security Through the merging of these three companies and skillsets, the initiative aims to help Europe's industries accelerate production cycles and scale innovation. Jacomo Corbo, CEO and Co-Founder of PhysicsX, says: "Industrial competitiveness increasingly hinges on AI enablement - and that, in turn, makes access to scaled GPU compute infrastructure a sovereign imperative. Deutsche Telekom and NVIDIA are building the world's first Industrial AI Cloud for European manufacturers, and we're thrilled that the PhysicsX platform will be a core part of its software stack." "Together with Deutsche Telekom, NVIDIA and Siemens, our shared mission is to make the most powerful AI both available and consumable to industrial enterprises - to hyper-accelerate every stage of the product lifecycle, from engineering to manufacturing to operations." Building resilience. The PhysicsX AI-native platform is a meeting point for data, models and compute. It brings NVIDIA AI infrastructure to industrial organisations, enabling integration of governed product data, training of physics-informed models and their deployment into engineering workflows. Through integrations to Siemens, PhysicsX fits into how engineers already work. It provides seamless data integration to avoid workflow disruption and connects to Teamcenter for product data management, access control and change processes. This lets it operate within CAE environments to automate data generation, enable simulation-in-the-loop learning and support cross-disciplinary collaboration. PhysicsX runs natively on NVIDIA accelerated computing and integrates with NVIDIA systems and the wider PhysicsX stack. Together, these make production-ready physical AI possible, delivering real-time inference, high-fidelity digital twins and agentic generative workflows that continuously improve. The result is a data-driven loop spanning design, simulation and validation through to continuous manufacturing and operations. It strengthens supply chain and production resilience and allows businesses to deploy industrial AI at pace. "Artificial intelligence is the backbone of the next industrial revolution," says Ferri Abolhassan, Board member at Deutsche Telekom and CEO T-Systems International GmbH. "The strength of Europe and Germany will be determined by whether we design the necessary infrastructure and measures ourselves," "With the Industrial AI Cloud, we have reached a milestone today - together with our partners and first customers - for a sovereign future." Through this partnership, the companies are working to turn cloud capability into real-world engineering impact across Europe's manufacturing industry. By integrating these systems, manufacturers could see new levels of efficiency and business resilience.
