Secure AI Infrastructure

Private AI infrastructure built for European organizations that need full control over their AI stack. From LLM gateways to vector databases to secure pipelines.

LLM Gateway

LiteLLM-based gateway with unified API for all major LLM providers. Rate limiting, cost tracking, per-user access control, and fallback chains.

Vector Databases

ChromaDB and pgvector integration for RAG pipelines. Embedding management, similarity search, and document indexing under your control.

Secure Pipelines

End-to-end encrypted AI inference pipelines. No data leaves your infrastructure. Full audit trails and compliance logging.

Why self-hosted AI infrastructure?

Using cloud-based AI services like OpenAI API means sending your proprietary data to third parties. For regulated industries and EU organizations, this creates GDPR and AI Act compliance risks.

Self-hosted AI infrastructure gives you full control over data, models, and access. You decide which models run, who can use them, and where the data is stored.
