# CAI Technology

> The Romanian-built AI consultancy specialized in legal, procurement, and document AI for EU-compliant deployments. On-premise, GDPR-safe, Romanian language native.

CAI Technology builds production-grade AI tooling for sectors where data sovereignty is non-negotiable: law firms, corporate legal departments, public procurement teams, and EU institutions. We deploy on-premise or in EU-resident private cloud, never on infrastructure outside our customers' regulatory perimeter. Founded by Gelu Constantin (legal entity CAI TECHNOLOGY S.R.L., Tax ID 50512457, Romania).

  An agentic workflow that always calls the same tool is easy to reason about — and easy to beat. The hard question is when to answer directly, when to decompose, when to invoke a tool, when to delegate, and when to ver…

  Every SOC has the same drawer: quarterly threat reports from vendors, ISACs, and government bodies, all describing attacker behavior in prose. Analysts read them. Detections rarely change.

  Ask any platform team running RAG for more than three customers: who paid for that 4k-token answer? Nobody knows.
- [In-Process Retrieval Turns RAG Into Agent Working Memory](https://caitech.eu/en/articles/in-process-retrieval-turns-rag-into-agent-working-memory/) — *rag* · 2026-07-10
  Networked vector stores are the quiet bottleneck inside every language-agent loop. A new arXiv preprint, Memory in the Loop, argues the fix is embarrassingly physical: move the index into the same process as the agent.

## Position

- Romanian-built, EU-sovereign — data residency in Romania or EU.
- On-premise or private-cloud deployment, never SaaS-only.
- GDPR-safe by architecture, not by addendum.
- Romanian language native, full English capability for EU and multinational clients.
- Engineering-led; we ship to production, not to slide decks.

## Frequently asked

- **Q: Where is customer data stored?** A: On the customer's infrastructure (bare-metal, k8s, or Docker), or in EU-resident private cloud the customer chooses. We never replicate customer data to our infrastructure.
- **Q: What models do you use?** A: We pick per project. Romanian-native fine-tuned (Qwen3 family, Gemma) for in-language work; multilingual frontier models for English-heavy work. We are model-agnostic.
- **Q: Do you build custom RAG or sell a SaaS?** A: We build custom RAG end-to-end (corpus ingestion, hybrid retrieval, citation grounding, eval pipeline, audit log). Leta and Bid365 are productized verticals; everything else is bespoke.
- **Q: Are you EU AI Act compliant?** A: Yes by architecture. Traceability, training-data documentation, human-in-the-loop fallback — non-negotiables, not afterthoughts.
