For organisations with strict data requirements or deep automation ambitions, self-hosting your own LLMs and AI agents gives you complete control over privacy, performance, and cost.

We design, deploy, and maintain a production-ready AI environment behind your firewalls inside your cloud or on-prem infrastructure.

Best for regulated, sensitive-data, enterprise or scale-up organisations that need total control, customisation, and the foundation for advanced multi-agent AI systems.

CREATING HOSTED AI SOLUTIONS IN PARTNERSHIP WITH

What is Self-hosted LLMS & AI Agents

elf-Hosted LLMs & Agents deliver a fully sovereign AI platform, deployed in your chosen environment (AWS, Azure, GCP, or on-prem). Your organisation needs:

AI Assistants - Running your internal workflows, content workflows, analysis, and decision support - with zero external data exposure.

AI Agents - Executing multi-step processes, interacting with your systems through APIs, retrieving data, updating records, and performing actions autonomously.

Your Own LLM Capacity - You choose the models (open-source, proprietary, fine-tuned) and maintain complete control over:

  • Data residency

  • Compliance

  • Cost per token

  • Operational security

  • Scaling

  • Evaluation, tuning, and updates

This is the highest level of AI control available today.

Why Choose Self-Hosted

Self-hosting isn’t for everyone - but for the right organisation, it is essential:

  1. Data never leaves your environment
    Essential for healthcare, finance, legal, government, insurance, infrastructure, and enterprise contracts.

  2. Predictable, lower long-term cost
    High-volume inference becomes dramatically cheaper when you control the runtime.

  3. Maximum control over model behaviour
    Modify, restrict, or fine-tune models to match your exact workflows and guardrails.

  4. Unlimited agent depth
    Agents can perform far more sophisticated actions when running inside your own network and connected to your systems natively.

  5. Multi-agent orchestration for mission-critical processes
    Agents coordinating tasks across systems becomes safer, faster, and more controllable when hosted internally.

  6. Zero dependency on third-party AI APIs
    No vendor lock-in. No pricing surprises. No data exposure.

If hosted is the smart choice for 80 percent of companies, self-hosted is the right choice for those with regulatory, operational, or strategic sovereignty needs.

How It Works

Our five-step implementation framework, ensures you get the right behind-the-firewall AI for your organisation.

1. Readiness, Compliance & Security Assessment

We work with your IT, security and data teams to define:

  • Compliance and regulatory requirements

  • Data boundaries & classification

  • Access controls & RBAC

  • Network topology

  • Approved models & hosting options

  • Integration inventory

  • Risk management & threat modelling

2. Architecture & Model Strategy Design

We design the full technical stack for your environment:

  • Model selection (Llama 3, Mistral, Mixtral, Phi, fine-tunes, hybrids)

  • GPU/CPU load planning & scaling strategy

  • Containerisation/orchestration (Kubernetes or equivalent)

  • RAG architecture (vector DB selection, ingestion pipelines)

  • Agent design + capability scoping

  • Observability & logging

  • Monitoring, safety, evaluation, and fallback logic

3. Assistant, Agent & Knowledge Engineering

We build the intelligence layer inside your environment:

  • Custom AI assistants

  • AI agents for task execution and multi-step workflows

  • RAG pipelines integrated with internal systems

  • Secure connectors & API interfaces

  • Fine-tuning or LoRA-tuning where appropriate

  • Departmental workflows (Support, Sales, Ops, Finance, HR)

  • Tone-of-voice, policy enforcement and reasoning guardrails

4. Private Deployment In Your Environment

We deploy your full AI stack inside your cloud or on-prem:

  • LLM hosting (GPU clusters or managed inference servers)

  • Vector database and embeddings

  • Safe tool use and agent execution sandbox

  • Access management + authentication

  • Audit logs, observability & alerting

  • Dashboards for usage, cost, and accuracy

  • Internal access interfaces (web, Slack, Teams, CRM, API)

5. Training, Rollout & Change Management

We ensure adoption across the organisation through:

  • Live onboarding sessions

  • Role-specific training

  • Change management planning

  • SOPs, playbooks and usage guidelines

  • Performance monitoring in early rollout

Continuous Optimisation & Multi-Agent Evolution

We continuously improve your AI system:

  • Add new agents

  • Add new multi-step workflows

  • Expand integrations

  • Improve accuracy

  • Tune prompts and behaviours

  • Evaluate and update models

  • Introduce multi-agent orchestration when appropriate

  • Quarterly roadmap reviews
