Private AI and Self-Hosted LLMs: Your Data, Your Keys, Your Control

Send one prompt to a hosted US cloud API and a copy of your data leaves your jurisdiction. We design and operate private AI that stays inside your perimeter: self-hosted LLMs, RAG copilots and AI agents on infrastructure you control. We are open-source-first and vendor-neutral, building around open standards like the OpenAI-compatible inference API, GGUF model weights and the Model Context Protocol rather than locking you to one tool. The result is GDPR and EU AI Act alignment by design, not bolted on afterwards.

What we build

  • Self-hosted LLM serving on open-weight models (e.g. Llama, Mistral, Mixtral, Qwen, DeepSeek), sized to your accuracy, latency and budget, served through inference engines we work across such as vLLM, Ollama, llama.cpp, SGLang, LocalAI and Hugging Face TGI
  • Private RAG copilots grounded in your own documents, wikis and databases, with retrieval and vector search running entirely on your infrastructure (e.g. pgvector, Qdrant, Weaviate, Milvus or Chroma, orchestrated with LangChain or LlamaIndex)
  • AI agents that act on your systems and tools through open interfaces like the Model Context Protocol, with no data sent to third-party APIs
  • Air-gapped and isolated deployments for regulated workloads in healthcare, legal, finance and the public sector
  • Model selection, fine-tuning and evaluation so you ship the right model for the job, and we adapt to your existing stack rather than imposing ours

Privacy and compliance built in

  • A PII protection layer that detects and redacts names, emails, financial and health data before prompts reach the model, built on open tooling (e.g. Microsoft Presidio) with optional reversible tokenisation so responses stay personalised
  • EU data residency offered as a capability, with engineering based in Europe, so prompts, documents and embeddings stay in your jurisdiction and outside CLOUD Act reach
  • No data ever used to train third-party models, and no telemetry leaving your network
  • GDPR and EU AI Act alignment, with Data Processing Agreements, auditable access controls and prompt and response logging you own
  • Encryption with keys you hold (BYOK/HYOK), on infrastructure you control, with confidential computing where the threat model calls for it

Run it on the right foundation

  • Deploy on your existing cloud, your dedicated GPU servers, or a sovereign open-source private cloud we build and operate for you
  • On-prem GPU infrastructure sized to real usage so the cost case holds over a two- to three-year horizon
  • Portable, vendor-neutral platforms across the CNCF ecosystem (e.g. Kubernetes, KubeVirt, OpenStack, Proxmox VE, Ceph) so there is no hyperscaler lock-in
  • DevOps and AIOps automation, with open observability via OpenTelemetry, to operate, monitor and scale your AI stack
  • Engineered in Europe, delivered from Amsterdam and Dubai, neutral on tooling and matched to your sovereignty and compliance needs
FAQ
Is ChatGPT GDPR compliant for business use?

The consumer version of ChatGPT is generally not GDPR compliant, because conversations may be retained and used for training with no Data Processing Agreement or EU data residency guarantee. A self-hosted or private LLM avoids this by keeping every prompt and document inside infrastructure you control, so no personal data leaves EU jurisdiction. We build the GDPR-compliant alternative around open models and open standards, not a single vendor.

What is private AI?

Private AI means running large language models, RAG pipelines and AI agents on infrastructure you control, on-premise or in a dedicated EU environment, rather than sending data to external cloud APIs. Your prompts, documents and model weights never leave your perimeter and are never used to train someone else's model, giving you full data sovereignty and alignment with GDPR and the EU AI Act by design.

Which open-source models and tools can run on-premise?

Capable open-weight models such as Llama, Mistral, Mixtral, Qwen and DeepSeek run well on your own GPU servers, with smaller models on a single 24GB GPU and 70B-class models on multi-GPU setups. We serve them through whichever inference engine fits, for example vLLM, Ollama, llama.cpp, SGLang, LocalAI or Hugging Face TGI, all exposing the OpenAI-compatible API so you are never locked in. We help you select, fine-tune and deploy the right combination for your accuracy, latency and budget.

How do you stop sensitive data and PII from leaking into an LLM?

We add a PII protection layer, typically built on open tooling like Microsoft Presidio, that detects and redacts names, emails, financial and health data before prompts reach the model, with optional reversible tokenisation so responses stay personalised. Combined with on-premise hosting and a local RAG and vector store, no sensitive information ever leaves your network.

Is self-hosting an LLM cheaper than using cloud APIs?

It depends on usage. For low or sporadic volume, cloud APIs are cheaper; for sustained, high-volume workloads, on-premise typically wins on total cost over a two- to three-year horizon, and the data-sovereignty benefit is structural rather than a line item. We size the hardware and architecture to your actual usage so the break-even works in your favour.
