Your data never leaves

Private AI Chatbot

For some organisations the blocker is not capability. It is that no data may leave the tenancy, jurisdiction or, in some cases, the building.

The problem

When a private deployment is genuinely necessary

Often it is not — and we will say so, because self-hosting carries real cost.

Managed enterprise API endpoints already offer data-residency options, no-training guarantees and contractual protections that satisfy many risk teams. Where they do, using them is cheaper, faster and better-performing.

A private deployment is warranted when a regulator, a contract or a national data law requires that data never transit a third-party service; when you operate in an air-gapped environment; or when volume is high enough that self-hosted inference economics beat per-token pricing. We help you determine which situation you are actually in before you commit to the GPU bill.

  • Regulatory or contractual prohibition on third-party processing
  • Air-gapped or restricted network environments
  • National data-residency law with no compliant managed region
  • Classified or highly sensitive material
  • Volume high enough for self-hosted economics to win
  • Sector policy that forbids external model APIs outright
Architecture

What a private deployment involves

01 Model selectionOpen-weight models sized to your hardware and quality bar — the capability gap versus frontier models is real and we quantify it.
02 Inference infrastructureGPU provisioning, serving stack, batching, quantisation and autoscaling within your environment.
03 Retrieval layerVector store and search running entirely inside the boundary.
04 ApplicationChat interface and APIs on private endpoints with your SSO.
05 OperationsMonitoring, model updates, capacity planning and a support arrangement.
06 Cost modelTotal cost of ownership — GPU, storage, operations and staffing — compared against managed alternatives.
  • No inference traffic leaves your boundary
  • Your identity provider, your network controls
  • Honest quality comparison before commitment
  • Handover with runbooks if you operate it yourself
How we deliver

Ten stages from first call to a system your team trusts

Every AI engagement runs this sequence. Small projects compress stages; regulated projects expand them. Nothing gets skipped silently.

Discovery

A working session with your operations and engineering leads to map the process, the systems it touches, and where the cost actually sits.

AI Opportunity Assessment

We score candidate use cases on data readiness, volume, error tolerance and payback, then rank them. Some come back "do not use AI for this" — you get that answer too.

Solution Architecture

Model selection, retrieval design, tool boundaries, data flow, failure modes and hosting topology, documented before code.

Proof of Concept

A narrow build against your real data to prove accuracy on the cases that matter, typically 2–4 weeks. Go / no-go decision at the end.

MVP

One workflow, end to end, in the hands of real users. Evaluation sets and quality thresholds are defined here, not retrofitted.

Production Development

Hardening: error handling, retries, fallbacks, cost controls, rate limits, observability, and a human escalation path for every automated decision.

Integration

Wiring into your CRM, ERP, HRMS, data warehouse, ticketing and messaging channels through APIs, webhooks and event queues.

Security Testing

Prompt-injection testing, access-control verification, PII handling review, dependency scanning and penetration testing before go-live.

Deployment

Staged rollout on your cloud or ours, with CI/CD, versioned prompts and models, and rollback in place from day one.

Monitoring & Optimization

Quality dashboards, drift detection, cost-per-transaction tracking and a retraining or re-prompting cadence agreed in writing.

Security & Governance

Security-conscious architecture, from the first design review

Enterprise AI fails on governance more often than on models. Every system we build is designed to support enterprise security requirements and to give your risk team answers rather than assurances.

Data privacy & residency

Your data stays in the region and tenancy you nominate. We architect for no-training-on-your-data configurations and document exactly which vendor endpoints see which fields.

Role-based access control

Retrieval and tool permissions inherit your existing roles. A user cannot surface a document through the AI that they could not open directly.

Authentication & authorization

SSO via OIDC/SAML, short-lived tokens for agent tool calls, and per-tool scopes so an agent holds the narrowest possible privilege.

Encryption

TLS in transit, AES-256 at rest, managed keys via your cloud KMS, and encrypted vector stores for embedded content.

API security

Gateway-level authentication, signed webhooks, IP allowlisting, request validation and quota enforcement on every exposed endpoint.

Audit logging

Every prompt, retrieval, tool call, model version and human override is logged with a trace ID, so any output can be reconstructed months later.

Data isolation

Per-tenant separation at the storage, index and key level for multi-entity groups and regulated environments.

Secure prompt handling

System instructions are server-side, user content is treated as untrusted input, and we test against prompt-injection and tool-abuse patterns.

PII protection

Detection, masking or tokenisation of personal data before it reaches a model, with configurable redaction policies per field.

Human approval workflows

High-impact actions — payments, refunds, contract sends, record deletion — route to a named approver instead of executing autonomously.

Monitoring & anomaly detection

Alerting on unusual tool usage, cost spikes, refusal rates and quality regressions.

Rate limiting & abuse control

Per-user and per-tenant throttles, spend caps and circuit breakers so a runaway loop cannot become a runaway invoice.

Secure deployment

Private networking, secrets in a managed vault, immutable builds, dependency scanning, and infrastructure as code.

FAQ

Questions enterprise buyers ask us first

Can an AI chatbot run entirely on our own infrastructure?
Yes. Open-weight models such as Llama and Mistral run in your cloud tenancy or on-premises with GPU capacity, with the retrieval layer and application alongside. No inference traffic leaves your boundary.
How does quality compare to a frontier model API?
For retrieval-grounded question answering over your own documents, a well-deployed open-weight model performs closer to frontier models than most people expect, because the facts come from retrieval rather than the model. For complex multi-step reasoning the gap is larger. We benchmark both against your evaluation set so the decision is evidence-based.
What does a private deployment cost?
Build cost is comparable to a managed deployment; infrastructure is where it differs. GPU capacity typically runs from a few thousand dollars a month upward depending on model size and concurrency, plus operational overhead. We model total cost of ownership against managed alternatives before you commit.
Do we need our own ML operations team?
Not necessarily. We can operate the deployment under a support arrangement, or hand over with runbooks, monitoring and documentation for your infrastructure team. Both are common.
