What changes for you

Meta AI you own outright

Self-hosted meta AI on your infrastructure data residency, ownership, no lock-in.

  • Predictable inference cost

    We size the GPU cluster for your workload, instrument utilisation, and give you a fixed monthly infra cost before we deploy. No per-token surprises. Scale up by adding nodes, not by negotiating a new pricing tier.

  • Domain accuracy via fine-tuning

    We fine-tune on your proprietary dataset - with an eval harness that proves the fine-tuned model outperforms the base model on your actual tasks before it touches production. Accuracy is a metric, not a feeling.

  • You own everything

    The weights, the fine-tuning data, the prompts, the eval suite, the deployment config. If you want to take it in-house on day 180, you walk away with everything. No royalty, no lock-in.

Where most integrations break

Why public LLM APIs don’t fit

Vendor lock-in, unpredictable inference bills, and data residency rules rule out public APIs.

Who we work with

Built for the infrastructure owner

Whoever owns inference and data: we deploy meta AI where your data must stay.

CTO · VP Engineering

We need GPT-4o quality without GPT-4o's vendor lock-in.

We deploy Llama with the same eval rigour, observability and handoff docs just on your infra, with your keys, on your bill.
  • Model selection · quantisation · GPU sizing
  • Eval harness · CI/CD · LangSmith tracing
  • Full IP transfer · runbooks · on-call docs
CIO · IT Director

Legal says no data outside our Azure tenant.

Llama in your tenant. Your region, your keys, your audit logs. We've done this on AWS, Azure, GCP and bare-metal.
  • VPC deployment · no external API calls
  • SOC 2 controls · data redaction at the edge
  • Vendor risk documentation for your review board
CFO · Finance Director

Our AI inference bill is growing faster than our revenue.

We model the break-even between per-token pricing and self-hosted infra at your current volume. If Llama wins the economics, we build the business case with you.
  • Fixed monthly infra cost · no per-token billing
  • Break-even model before we start
  • Typically 60–80% cost reduction vs GPT-4o at scale
Head of Legal

Our clients' data cannot touch any cloud AI vendor.

Llama on your hardware means zero egress, zero subprocessor risk, zero vendor data-handling agreement to explain to clients.
  • Air-gapped deployment options available
  • No external API calls at any point in the pipeline
  • Data stays within your legal jurisdiction
VP Product

We need domain-specific accuracy our current model can't match.

Every engagement ships with a baseline, a target and a dashboard. ROI is a number, not a narrative.
  • QLoRA fine-tuning on your proprietary data
  • Eval-proven accuracy before production access
  • Retraining pipeline included at handoff
CISO · Head of Security

We can't pass a vendor risk assessment for any public LLM API.

Zero vendor risk - Llama is open-weight. You hold the weights, you control the serving, you own the audit logs.
  • No vendor subprocessor · no data sharing
  • You own the model weights and deployment config
  • Full audit trail within your own infrastructure

Word of mouth

What clients tell their peers.

Real names, real companies, real numbers. Video on the left, written notes on the right - choose whichever feels more honest.
