A European ChatGPT alternative for organizations that need a European counterparty, not a rebadged endpoint of a US service. French company under EU law, EU-hosted customer database, native GDPR Article 28 DPA, hardware-sealed in Intel TDX.
Forrester estimates Europe will spend €1.5 trillion on cloud and AI infrastructure by 2030. Where that money goes determines who controls European data.
01, THE €1.5T SOVEREIGNTY PROBLEM
Forrester estimates European organizations will spend €1.5 trillion on cloud and AI infrastructure between now and 2030. The vast majority of that spend currently flows to three US hyperscalers and OpenAI. The result is a strategic dependence comparable to historical energy imports, except this time the dependency is on inference pipelines that handle Europe's most sensitive data.
VoltageGPU is one of the European alternatives. We are not the largest. We do not claim to replace OpenAI for every workload. But for the workloads that actually require EU sovereignty, regulated industries, public sector, professional services handling client data, we provide a real alternative with hardware confidentiality US providers cannot match.
02, WHAT MAKES VOLTAGEGPU EU-SOVEREIGN
European controller, European staff
VOLTAGE EI is a French company headquartered in Solaize, near Lyon. SIREN 943 808 824. Founder and primary engineer based in France.
Provider-blind inference for confidential workloads
Every prompt runs inside an Intel TDX trust domain, encrypted with CPU-fused keys. The GPU provider is named in the DPA and sits outside the trust domain, so no operator in the path can read your prompt in clear.
Native GDPR Article 28 DPA
Data Processing Agreement is the default contract on every plan, free or paid. No negotiation required.
Intel TDX hardware sealing
AES-256 memory encryption fused into CPU silicon. Even VoltageGPU staff cannot read active inference sessions.
Provider-blind by design
No prompt logging, no training on user data, ECDSA-signed attestation evidence available per session.
No US parent, no US dependency
No corporate parent in the US. No CLOUD Act or FISA 702 exposure. Independent of US hyperscalers for confidential inference.

05, FAQ
Is VoltageGPU actually a European company?
European company. VOLTAGE EI is a French sole proprietorship registered with SIREN 943 808 824, based in Solaize, France. Founder Julien Aubry. There is no US parent, no US holding, no CLOUD Act or FISA 702 exposure for our confidential inference platform.
Why is the EU AI sovereignty conversation important?
Forrester estimates European organizations will spend €1.5 trillion on cloud and AI infrastructure by 2030, with most of that flowing to three US hyperscalers and OpenAI. That creates strategic dependence comparable to energy imports. EU alternatives, including VoltageGPU, Mistral, OVHcloud, Scaleway, exist to give European companies real choice.
How is VoltageGPU different from Mistral Le Chat?
Both are EU-based and refuse training on user prompts. The differentiator is hardware: Mistral runs on standard cloud VMs and a Mistral operator with infrastructure access could technically inspect inference memory. VoltageGPU runs every confidential session inside an Intel TDX enclave, memory is encrypted with AES-256 keys fused into the CPU, even our own engineers cannot read prompts.
Will my existing ChatGPT prompts work?
Yes. The chat experience is intentionally familiar. Most ChatGPT prompts work without modification on Qwen3.5-397B-TEE. We also provide an OpenAI-compatible API endpoint, so developers migrating from gpt-4o or gpt-4o-mini only need to change the base URL and model name.
Does VoltageGPU comply with the EU AI Act?
Yes. We publish transparency notices, model cards for every TEE model, and provide human oversight features. Because we are an EU-located controller and our core business is regulated AI infrastructure, we are positioned for the AI Act's obligations on general-purpose AI providers and high-risk deployers.
