Cloud-Private or On-Site · Zero External Leakage

Nerdster Vault

Custom AI built around your workflows, deployed where your data already lives. Run it on a dedicated cloud silo we set up and manage for you, or fully on-site air-gapped on hardware you own. Either way, your data never trains a public model and never leaves your perimeter.

Your data. Your model. Your cloud or your building.

We don't deploy a generic LLM behind your firewall. We train the model on your proprietary data, documents, policies, case files, and processes, so the AI has complete domain understanding before it touches a live workflow.
📚

Trained on Your Data

Your documents, contracts, policies and case files are ingested and used to fine-tune the model inside your perimeter, never externally. The AI learns your terminology, your precedents, your processes.

Cloud Silo or On-Site

Two deployment modes. We can run Vault in a dedicated cloud silo (AWS London, Azure UK South or your own tenant) and manage it for you, or install it fully on-site air-gapped on hardware you own. Same model, same controls, you choose where it lives.

Purpose-Built Agents

Custom workflow agents built on your trained model. Understands your document types, approval flows and compliance obligations, not generic chatbot behaviour.
