Edge computing and DDoS protection at 300+ cities. Cache, compute, and secure traffic before it hits your origin.

Vector database that turns embeddings into retrieval. Stop hallucinating—ground your LLM in actual documents.

European LLM provider cutting inference costs and vendor lock-in. Open-weight models + commercial API for operators who need speed, privacy, and control.
